Detailed Description

General model for any prime mover with a PID governor, used primarily for combustion turbine and combined cycle units. This model can be used to represent a variety of prime movers controlled by PID governors. It is suitable, for example, for representation of

Member Data Documentation

◆ aset

IEC61970::Base::Domain::Float IEC61970::Dynamics::StandardModels::TurbineGovernorDynamics::GovCT1::aset

Acceleration limiter setpoint (Aset). Unit = PU/sec. Typical Value = 0.01.

◆ db

IEC61970::Base::Domain::PU IEC61970::Dynamics::StandardModels::TurbineGovernorDynamics::GovCT1::db

Speed governor dead band in per unit speed (db). In the majority of applications, it is recommended that this value be set to zero. Typical Value = 0.

◆ dm

IEC61970::Base::Domain::PU IEC61970::Dynamics::StandardModels::TurbineGovernorDynamics::GovCT1::dm

Speed sensitivity coefficient (Dm). Dm can represent either the variation of the engine power with the shaft speed or the variation of maximum power capability with shaft speed. If it is positive it describes the falling slope of the engine speed verses power characteristic as speed increases. A slightly falling characteristic is typical for reciprocating engines and some aero- derivative turbines. If it is negative the engine power is assumed to be unaffected by the shaft speed, but the maximum permissible fuel flow is taken to fall with falling shaft speed. This is characteristic of single-shaft industrial turbines due to exhaust temperature limits. Typical Value = 0.
