Description

≡Attributes (10)

alias : [1..1] — An alternative name used by a system, project, or user community that differs from the default or preferred name. {F9DC1A02-F831-45d2-8A40-7A7AAA16D13F}
device : [1..1] — A name used to identify a device, component, or object instance within a vendor system, device platform, or operational system. Such names are typically assigned by manufacturers, device firmware, automation systems, metering systems, or enterprise applications (e.g., ERP, asset management, monitoring platforms) and are used for configuration, monitoring, or asset tracking. Note: Device names are often defined within the scope of a particular vendor, system, or installation and are therefore typically unique only within that system context. Example: "IED_BAY3_01", "Meter_102394", "SAP_EQ_000457812" {93B6D6C3-4034-4163-BAEB-48DD192223E3}
eic : [1..1] — An Energy Identification Code name, typically used in European energy market and interoperability contexts. Example: "10YNO-0--------C" {FCF21086-192A-43aa-BE76-AB29C18810CE}
iec61850 : [1..1] — A name used in IEC 61850 contexts (e.g., IED name, logical node naming, object references, or related 61850 naming forms as specified by the profile).Example: "LD0/XCBR1.Pos.stVal" {B3F83D03-1CA2-4c48-8B8E-5B3955D0028C}
label : [1..1] — A short name primarily intended for local display, compact user interfaces, and single-line diagrams. A label is generally preferred to be short and readable rather than globally unique. Example: "T1", "Bay3" {B094413D-CB11-4fbb-AB92-5EA8CE716CF5}
local : [1..1] — A name used within a local naming scope (site, system, organisation, or sub-hierarchy) where meaning is derived from the local context. The name shall be unique inside the container, e.g. substation. {FA364C1A-C75D-465d-A6F6-E0DCF4AB3443}
path : [1..1] — A hierarchical name constructed from a sequence of name segments representing containment, structure, or functional decomposition. Example: "SubstationA/Bay3/Breakder1" {0FBB7809-BD6C-4aca-9F31-B6345C5EE91E}
rds : [1..1] — A name following the Reference Designation System (RDS) defined in IEC 81346, used to uniquely identify systems, functions, and equipment within engineering documentation and technical installations. RDS names express the position or role of an object within a structured engineering hierarchy and are widely used in electrical engineering documentation, drawings, and plant documentation. Note: The Reference Designation System (RDS) provides a structured identification scheme where each segment represents an aspect of an object such as function ("="), product ("-"), or location ("+").Example: "=N01+SA1-Q01" {84174F58-EEAD-4b3a-A561-B719CD5605C8}
urn : [1..1] — A name expressed as a Uniform Resource Name (URN), a persistent identifier defined using a registered namespace according to IETF RFC 8141.URN namespaces provide globally unique identifiers without requiring a resolvable URL and are commonly defined by standards bodies, industry communities, or organisations. Note: URN identifiers use the general structure: "urn:<namespace>:<identifier>" where <namespace> identifies a registered namespace and <identifier> is the value assigned within that namespace. Example: Object Identifier (OID) "urn:oid:1.3.6.1.4.1.4555", UUID namespace "urn:uuid:550e8400-e29b-41d4-a716-446655440000", EIC namespace "urn:eic:10YNO-0--------C"{6069EBFC-69EA-445a-BC89-1F72E55EAD73}
uuid : [1..1] — A designation expressed as a Universally Unique Identifier (UUID) as defined in IETF RFC 4122 (and its successor RFC 9562). UUIDs are 128-bit identifiers designed to be globally unique without requiring a central registration authority. UUID names are commonly used in software systems and data exchanges to provide stable identifiers across distributed systems. Note: A UUID is typically represented as a 36-character string consisting of hexadecimal digits grouped in five sections separated by hyphens. Example: "550e8400-e29b-41d4-a716-446655440000" {2A263A27-A329-4023-916D-E288389864BA}

▶⚙Namei

Description (destination, redlined)

~~The Name class, in possible combination with a name type and a naming authority provides the means to define any number of names or alternative identifiers for an object.~~ The Name class allows for the introduction of one of more alternative names or alternative identifiers for an object identified by association to IdentifiedObject, which need to have associated NameType or nameKind. Example: display label such as “T1”; alternative mRID; alternative address text; serial number of the device; etc.

▶⚙NameTypei

Description (destination, redlined)

Type of name. Possible values for attribute 'name' are implementation dependent but standard profiles may specify types. An enterprise may have multiple IT systems each having its own local name for the same object, e.g. a planning system may have different names from an EMS. An object may also have different names within the same IT system, e.g. localName as defined in CIM version 14. The definition from CIM14 is:The localName is a human readable name of the object. It is a free text name local to a node in a naming hierarchy similar to a file directory structure. A power system related naming hierarchy may be: Substation, VoltageLevel, Equipment etc. Children of the same parent in such a hierarchy have names that typically are unique among them. A specification that defines a non-standard name type used to classify and constrain Name object beyond the standardised NameKind enumeration. NameType provides constraints on name object and its relationships. NameType attributes carry constraints that can be used for restriction and validation of Name objects. It is not possible to use profiles to validate Name objects that are not using NameKind enumeration so NameType carries attributes that can provide restrictions on Name objects.

▶Domaini

Description

The domain package defines primitive datatypes that are used by classes in other packages. Stereotypes are used to describe the datatypes. The following stereotypes are defined:<<enumeration>> A list of permissible constant values.<<Primitive>> The most basic data types used to compose all other data types.<<CIMDatatype>> A datatype that contains a value attribute, an optional unit of measure and a unit multiplier. The unit and multiplier may be specified as a static variable initialized to the allowed value.<<Compound>> A composite of Primitive, enumeration, CIMDatatype or other Compound classes, as long as the Compound classes do not recurse.For all datatypes both positive and negative values are allowed unless stated otherwise for a particular datatype.

▶⚙DateTZ«ConstrainedPrimitive»i

Description

A restriction on Date that explicitly requires a time zone reference to ensure consistency across different regions and avoid ambiguity in global contexts. Without a time zone, a date might refer to different 24-hour periods depending on the location, potentially causing misinterpretation in scheduling, record-keeping, and historical data. Example: 2024-12-25Z (Coordinated Universal Time) or 2024-12-25+02:00 (UTC+2).

▶⚙Double«ConstrainedPrimitive»i

Description

Represents positive and negative real numbers with double precision, offering greater accuracy compared to Float. Unlike Float, Double supports special symbols such as NaN (Not a Number), positive infinity, and negative infinity, making it suitable for scientific and engineering applications where such values are required. These special values are essential for handling undefined or unrepresentable mathematical results, such as division by zero (1.0 / 0.0 results in positive infinity) or the square root of a negative number (sqrt(-1.0) results in NaN). Example: 3.141592653589793, 1.79E+308 (maximum positive double), NaN (Not a Number).

▶⚙Token«ConstrainedPrimitive»i

Description

Represents textual values where leading and trailing white space, line breaks, tab characters, and carriage returns are prohibited. In addition, it is not allowed to have multiple internal white space characters. Additionally, multiple consecutive internal white space characters are not valid and should be collapsed into a single space. This constraint ensures consistency in data processing, preventing unintended mismatches in validation and duplicate detection. Unlike Normalised, Token is designed to avoid issues when values are embedded in URIs, filenames, or query strings, where multiple spaces could cause encoding or interpretation problems.Example: "This is an example." is allowed for a Normalised string but not allowed for Token. "This is an example." is allowed for both Token and Normalised.

▶⚙IRI«Primitive»i

Description

An IRI (Internationalized Resource Identifier) within an RDF graph is a Unicode string that conforms to the syntax defined in RFC 3987.The primitive is serialized as rdf:resource in RDFXML.IRIs in the RDF abstract syntax must be absolute, and may contain a fragment identifier.IRI equality: Two IRIs are equal if and only if they are equivalent under Simple String Comparison according to section 5.1 of [RFC3987]. Further normalization must not be performed when comparing IRIs for equality.IRIs are a generalization of URIs [RFC3986] that permits a wider range of Unicode characters. Every absolute URI and URL is an IRI, but not every IRI is an URI. When IRIs are used in operations that are only defined for URIs, they must first be converted according to the mapping defined in section 3.1 of [RFC3987]. A notable example is retrieval over the HTTP protocol. The mapping involves UTF-8 encoding of non-ASCII characters, %-encoding of octets not allowed in URIs, and Punycode-encoding of domain names.

▶⚙UnitSymbol«enumeration»i

Description

The derived units defined for usage in the CIM. In some cases, the derived unit is equal to an SI unit. Whenever possible, the standard derived symbol is used instead of the formula for the derived unit. For example, the unit symbol Farad is defined as "F" instead of "CPerV". In cases where a standard symbol does not exist for a derived unit, the formula for the unit is used as the unit symbol. For example, density does not have a standard symbol and so it is represented as "kgPerm^3". With the exception of the "kg", which is an SI unit, the unit symbols do not contain multipliers and therefore represent the base derived unit to which a multiplier can be applied as a whole. Every unit symbol is treated as an unparseable text as if it were a single-letter symbol. The meaning of each unit symbol is defined by the accompanying descriptive text and not by the text contents of the unit symbol.To allow the widest possible range of serializations without requiring special character handling, several substitutions are made which deviate from the format described in IEC 80000-1. The division symbol "/" is replaced by the letters "Per". Exponents are written in plain text after the unit as "m^3". The letters "deg" are used instead of the degree symbol. Any clarification of the meaning for a substitution is included in the description for the unit symbol.Non-SI units are included in list of unit symbols to allow sources of data to be correctly labelled with their non-SI units (for example, a GPS sensor that is reporting numbers that represent feet instead of meters). This allows software to use the unit symbol information correctly convert and scale the raw data of those sources into SI-based units. The integer values are used for harmonization with IEC 61850.

Baseline description

Per length phase impedance matrix entry describes impedance and conductance matrix element values for a specific row and column of the matrix. The phases to which each entry applies can be determined by means of the row and column attributes which bind to a sequence number provided in either ACLineSegmentPhase or WirePosition (which also specify phase). Due to physical symmetry that is reflected in the matrix, only the lower triangle of the matrix is populated with the row and column method. That is, the column attribute is always less than or equal to the row attribute.

▶⚙StaticVarCompensatori

Description (destination, redlined)

A facility for providing variable and controllable shunt reactive power. The SVC typically consists of a stepdown transformer, filter, thyristor-controlled reactor, and thyristor-switched capacitor arms.The SVC may operate in fixed MVar output mode or in voltage control mode. When in voltage control mode, the output of the SVC will be proportional to the deviation of voltage at the controlled bus from the voltage setpoint. The SVC characteristic slope defines the proportion. If the voltage at the controlled bus is equal to the voltage setpoint, the SVC MVar output is zero.

▶Dynamicsi

Description

The CIM dynamic model definitions reflect the most common IEEE or, in the case of wind models, IEC, representations of models as well as models included in some of the transient stability software widely used by utilities. These dynamic models are intended to ensure interoperability between different vendors’ software products currently in use by electric utility energy companies, utilities, Transmission System Operators (TSOs), Regional Transmission Organizations (RTOs), and Independent System Operators (ISOs). It is important to note that each vendor is free to select its own internal implementation of these models. Differences in vendor results, as long as they are within accepted engineering practice, caused by different internal representations, are acceptable.Unless explicitly stated otherwise, the following modelling conventions are followed:- limited integrators are of the non-windup type;- it shall be possible to enter a time constant of zero (where it makes sense).The information in the entire clause "Common Information Model Dynamics package" is reproduced from the UML with the permission of UCAIug.

This subclause describes the standard interconnections for various types of equipment. These interconnections are understood by the application programs and can be identified based on the presence of one of the key classes with a relationship to the static power flow model: SynchronousMachineDynamics, AsynchronousMachineDynamics, EnergyConsumerDynamics or WindTurbineType3or4Dynamics. The relationships between classes expressed in the interconnection diagrams are intended to support dynamic behaviour described by either standard models or user-defined models.In the interconnection diagrams, boxes which are black in colour represent function blocks whose functionality can be provided by one of many standard models or by a user-defined model. Blue boxes represent specific standard models. A dashed box means that the function block or specific standard model is optional.

▶SynchronousMachineDynamicsi

Description

For conventional power generating units (e.g., thermal, hydro, combustion turbine), a synchronous machine model represents the electrical characteristics of the generator and the mechanical characteristics of the turbine-generator rotational inertia. Large industrial motors or groups of similar motors can be represented by individual motor models which are represented as generators with negative active power in the static (power flow) data. The interconnection with the electrical network equations can differ among simulation tools. The tool only needs to know the synchronous machine to establish the correct interconnection. The interconnection with the motor’s equipment could also differ due to input and output signals required by standard models.

▶⚙SynchronousMachineDetailedi

Description

All synchronous machine detailed types use a subset of the same data parameters and input/output variables. The several variations differ in the following ways:- the number of equivalent windings that are included;- the way in which saturation is incorporated into the model;- whether or not “subtransient saliency” (X''q not = X''d) is represented.It is not necessary for each simulation tool to have separate models for each of the model types. The same model can often be used for several types by alternative logic within the model. Also, differences in saturation representation might not result in significant model performance differences so model substitutions are often acceptable.

▶AsynchronousMachineDynamicsi

Description

An asynchronous machine model represents a (induction) generator or motor with no external connection to the rotor windings, e.g. a squirrel-cage induction machine. The interconnection with the electrical network equations can differ among simulation tools. The program only needs to know the terminal to which this asynchronous machine is connected in order to establish the correct interconnection. The interconnection with the motor’s equipment could also differ due to input and output signals required by standard models.The asynchronous machine model is used to model wind generators type 1 and type 2. For these, normal practice is to include the rotor flux transients and neglect the stator flux transients.

▶TurbineGovernorDynamicsi

Description

The turbine-governor model is linked to one or two synchronous generators and determines the shaft mechanical power (Pm) or torque (Tm) for the generator model. Unlike IEEE standard models for other function blocks, the three IEEE turbine-governor standard models (GovHydroIEEE0, GovHydroIEEE2, and GovSteamIEEE1) are documented in IEEE Transactions, not in IEEE standards. For that reason, diagrams are supplied for those models.A 2012 IEEE report, Dynamic Models for Turbine-Governors in Power System Studies, provides updated information on a variety of models including IEEE, vendor and reliability authority models. Fully incorporating the results of that report into the CIM dynamics model is a future effort.

▶OverexcitationLimiterDynamicsi

Description

Overexcitation limiters (OELs) are also referred to as maximum excitation limiters and field current limiters. The possibility of voltage collapse in stressed power systems increases the importance of modelling these limiters in studies of system conditions that cause machines to operate at high levels of excitation for a sustained period, such as voltage collapse or system-islanding. Such events typically occur over a long time frame compared with transient or small-signal stability simulations.

▶VoltageCompensatorDynamicsi

Description

Synchronous machine terminal voltage transducer and current compensator models adjust the terminal voltage feedback to the excitation system by adding a quantity that is proportional to the terminal current of the generator. It is linked to a specific generator (synchronous machine).Several types of compensation are available on most excitation systems. Synchronous machine active and reactive current compensation are the most common. Either reactive droop compensation and/or line-drop compensation can be used, simulating an impedance drop and effectively regulating at some point other than the terminals of the machine. The impedance or range of adjustment and type of compensation should be specified for different types. Care shall be taken to ensure that a consistent PU system is utilized for the compensator parameters and the synchronous machine current base.For further information see IEEE 421.5-2005, 4 and IEEE 421.5-2016, 5.

▶LoadDynamicsi

Description

Dynamic load models are used to represent the dynamic real and reactive load behaviour of a load from the static power flow model. Dynamic load models can be defined as applying either to a single load (energy consumer) or to a group of energy consumers. Large industrial motors or groups of similar motors can be represented by a synchronous machine model (SynchronousMachineDynamics) or an asynchronous machine model (AsynchronousMachineDynamics), which are usually represented as generators with negative active power output in the static (power flow) data.

Both voltage and frequency support can be achieved by various means. These features can minimize solar PV inverters generation potential negative impacts due to remote or local system grid events, voltage and/or frequency. The IEEE 1547-2018 standard enables new DER to have the capabilities for grid-supportive functionality, and the applicable authorities governing interconnection requirements can utilize these advanced features to provide more reliable and resilient energy to their customers as the power system continues to evolve.
