Voltage control for wind generators
First Claim
Patent Images
1. A wind turbine generator control system comprising:
- a reactive power regulator to control reactive power production by the wind turbine generator by adjusting a voltage setpoint to a voltage regulator, the reactive power regulator having a first time constant; and
a voltage regulator coupled with the reactive power regulator to control real power production by the wind turbine generator by generating a signal to indicate a wind turbine rotor current, the voltage regulator having a second time constant, wherein the first time constant is numerically greater than the second time constant.

Abstract
A wind turbine generator control system includes relatively fast regulation of voltage near the individual generators with relatively slower overall reactive power regulation at a substation or wind farm level. The setpoint of the relatively fast voltage regulator is adjusted by the relatively slow reactive power regulator. The fast voltage regulation can be at the generator terminals or at a synthesized remote point.
