Abstract
A voltage control system for a wind turbine generator may include a reactive power regulator configured to control reactive power production by the wind turbine generator by adjusting a voltage setpoint for the generator. The reactive power regulator may have a first time constant and the voltage setpoint may be defined between an upper limit and a lower limit. The system may also include a voltage limit regulator configured to adjust at least one of the upper limit or the lower limit for the voltage setpoint based on a voltage-related parameter. In addition, the system may include a voltage regulator coupled to the reactive power regulator. The voltage regulator may be configured to control real power production by the wind turbine generator based on the voltage setpoint. The voltage regulator may have a second time constant, wherein the first time constant is numerically greater than the second time constant.
