Abstract

The invention discloses a wind power generator optimizing control system and a wind power generator optimizing control method based on PI (Proportion Integral) regulation. A yaw system and a variable pitch control system of a wind power generator are combined, and a unified control method is adopted; when wind speed is relatively low, the yaw system automatically regulate the windward direction of the wind power generator, so that the wind power generator can obtain the maximum wind energy; and when the wind speed surpasses rated wind speed, the variable pitch control system starts up to regulate the pitch angles of fan blades, so that the wind power generator always runs at the maximum power.

Description

technical field [0001] The invention belongs to the field of new energy power generation, relates to wind power generation technology and new energy development technology in smart grids, and in particular to a wind power generator optimization control system and control method based on PI regulation. Background technique [0002] The proportion of wind power generation in the power system is increasing day by day. The areas rich in wind power resources in my country are mostly distributed in the central and western regions where the power grid is relatively weak. The grid connection of a large number of wind turbines has brought great challenges to the normal operation of the existing power system. [0003] The yaw system is a unique control system for wind turbines. It is mainly composed of three parts: yaw measurement, yaw drive transmission, and cable protection device. It mainly realizes two functions. One is to make the cabin track the changing and stable wind direction...
