Abstract
The invention provides a reactive voltage control system and method for wind power field of double-fed wind power-generating unit. The system comprises dispatching center equipment, a power management module for the wind power field and a plurality of controllers for the double-fed wind power-generating unit, wherein the dispatching center equipment is used for calculating a reactive power set value of the wind power field; the power management module for the wind power field is used for distributing the reactive power set value in the wind power field; and the controllers for the double-fed wind power-generating unit are used for controlling corresponding double-fed wind power-generating unit to perform reactive power compensation. According to the reactive voltage control system and the reactive voltage control method for the wind power field of the double-fed wind power-generating unit, the reactive output capability of the double-fed wind power-generating unit can be fully exerted.
