RotatingMachineDynamics

Type: object

Abstract parent class for all synchronous and asynchronous machine standard models.

 No Additional Properties

root Ravens.CimObjectType
Type: string

Used in RAVENS Schema to identify the corresponding CIM Object Type of the JSON object.

root DynamicsFunctionBlock.enabled
Type: boolean

Function block used indicator.
true = use of function block is enabled
false = use of function block is disabled.

root RotatingMachineDynamics.damping
Type: number

Damping torque coefficient (D) (>= 0). A proportionality constant that, when multiplied by the angular velocity of the rotor poles with respect to the magnetic field (frequency), results in the damping torque. This value is often zero when the sources of damping torques (generator damper windings, load damping effects, etc.) are modelled in detail. Typical value = 0.

root RotatingMachineDynamics.inertia
Type: object or number

Inertia constant of generator or motor and mechanical load (H) (> 0). This is the specification for the stored energy in the rotating mass when operating at rated speed. For a generator, this includes the generator plus all other elements (turbine, exciter) on the same shaft and has units of MW x s. For a motor, it includes the motor plus its mechanical load. Conventional units are PU on the generator MVA base, usually expressed as MW x s / MVA or just s. This value is used in the accelerating power reference frame for operator training simulator solutions. Typical value = 3.

root AsynchronousMachineUserDefined.proprietary
Type: boolean

true = user-defined model is proprietary with behaviour mutually understood by sending and receiving applications and parameters passed as general attributes
false = user-defined model is explicitly defined in terms of control blocks and their input and output signals.

root IdentifiedObject.aliasName
Type: string

The aliasName is free text human readable name of the object alternative to IdentifiedObject.name. It may be non unique and may not correlate to a naming hierarchy.
The attribute aliasName is retained because of backwards compatibility between CIM relases. It is however recommended to replace aliasName with the Name class as aliasName is planned for retirement at a future time.

root IdentifiedObject.mRID
Type: string

Master resource identifier issued by a model authority. The mRID is unique within an exchange context. Global uniqueness is easily achieved by using a UUID, as specified in RFC 4122, for the mRID. The use of UUID is strongly recommended.
For CIMXML data files in RDF syntax conforming to IEC 61970-552, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements.

root IdentifiedObject.name
Type: string

The name is any free human readable and possibly non unique text naming the object.
