voltage control system for a wind turbine generator and method for controlling a wind turbine generator

摘要

voltage control system for a wind turbine generator and method for controlling a wind turbine generator is a voltage set point for a wind turbine generator. The system may include a reactive power regulator configured to control reactive power production by the wind turbine generator by setting a voltage set point for the generator. the reactive power regulator may have a first time constant and the voltage set point may be set 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 or lower limit for the voltage set point based on the system voltage related parameter. In addition, the system may include a voltage regulator coupled to the reactive power regulator. The voltage regulator can be configured to control actual power output by the wind turbine generator based on the voltage set point. the voltage regulator may have a second time constant, wherein the first time constant is numerically greater than the second time constant.
