Wind Farm - Synchronous Generator and Full Scale Converter (Type 4) Detailed Model

Overview

Detailed 10 MW Type 4 wind farm with synchronous generator, diode rectifier, boost converter, and grid-side PWM converter for dynamic and disturbance studies.

This example shows a 10 MW wind farm made of five 2 MW Type 4 wind turbines connected to a 25 kV distribution system and exporting power to a 120 kV grid. It is a valuable model for renewable integration studies and converter-rich wind plant behavior.

Each turbine uses a synchronous generator, diode rectifier, DC-DC PWM boost converter, and DC/AC PWM converter. The detailed converter representation captures harmonics and short-timescale control dynamics.

This model complements the PV example with a utility-scale wind workflow. It is especially useful for discussing fault ride-through behavior, converter stress during voltage sags, and when to use detailed versus average or phasor representations.

Key Features

  • Detailed switching-level Type 4 representation
  • Constant wind-speed benchmark at 15 m/s
  • DC voltage regulation and reactive power control
  • Voltage sag test from a remote 120 kV fault
  • Initial-state setup for steady-state startup

Getting Started

  1. Run the model in steady state and inspect converter and turbine variables.
  2. Observe the programmed voltage sag at 0.03 s.
  3. Track DC bus voltage, output power, and reactive power during disturbance and recovery.
