Temporary Generator Data

Figure 1: Temporary Generator Data Dialog Box

Option Description
Model

The generator bus type used in modeling the power flow simulation. When you choose a model, those fields which are unavailable are dimmed.

  • Swing: A swing bus holds the bus voltage and angle constant. To do this there cannot be limits on the amount of MW or MVAR the swing machine can accept or provide.
  • PV: Constant power, constant voltage generator. This is also known as a regulated generator. This model tries to hold a user-specified bus voltage within generator MVAR limits.
  • PQG: Constant power, constant var generator. This is also known as an unregulated generator. This model holds the MVAR generation within given voltage limits.
Ctrl kV PU

The desired control voltage for a regulated generator (PV). The generator will try to control the voltage at the controlled bus to a given value. If the generator bus is the swing bus, this voltage serves as the reference voltage. The voltage is entered in per-unit.

Ctrl Angle

Controlled angle is used only when a generator is designated as a swing generator. The value is entered in degrees.

MW

The generator output MW. This may be actual operating or a rated value. This applies only to a PV or PQG generator.

MVAR

The generator output MVAR. This is only used when the generator is a constant power, constant var (PQG) machine or when a PV generator MVAR limit has been reached and the machine automatically switches to PQG.

MVAR Limits

The minimum and maximum MVAR limits for regulated generators (PV). The generator will switch to type PQG if these limits are violated.
