WECC Wind Type 4A Model (including the plant controller) - WTG4B - on infinite bus
Extends from Icons.Example (Icon for runnable examples).
Information
This test case consists in one simplified drive train model Wind Turbine park connected to an infinite bus which voltage is reduced to 0.5 pu from t = 1 s to t = 2 s, and which frequency is increased to 1.01 pu from t = 6 s to t = 6.5 s. This is a way to observe the behavior of the drive train of a Wind Turbine type 4A park in response to a voltage and frequency variation at its terminal.In this improved version, the type A drive train model with constant mechanical power (Pm) is replaced by the type B model (WTGT_B), a two-mass equivalent model including a lag block between electrical power (Pe) and mechanical power (Pm). This lag mimics the effect of pitch control after disturbances, allowing Pm to adapt and preventing steady-state errors in Pe without modeling the full pitch control loop.
