  "textContent": "A voltage control system for a wind turbine generator 110 is disclosed. The system includes a reactive power regulator 240 configured to control reactive power production by the wind turbine generator by adjusting a voltage setpoint for the generator. The reactive power regulator 240 may have a first time constant and the voltage setpoint may be defined between an upper limit and a lower limit. The system also includes a voltage limit regulator 248 configured to adjust at least one of the upper limit or the lower limit for the voltage setpoint based on a voltage-related parameter of the system. In addition, the system includes a voltage regulator 270 coupled to the reactive power regulator 240. The voltage regulator 270 may be configured to control real power production by the wind turbine generator based on the voltage setpoint. The voltage regulator 270 may have a second time constant, wherein the first time constant is numerically greater than the second time constant.",
