Abstract

The invention provides yaw control equipment of a wind driven generator set and a yaw control method of the wind driven generator set. The yaw control equipment of the wind driven generator set comprises a first obtaining unit, an optimizing unit, a second obtaining unit, a difference value determining unit and a yaw control unit. The first obtaining unit is used for obtaining historical wind regime data of the wind driven generator set within a preset time period; the optimizing unit is used for determining a yaw error angle threshold value and a time delay threshold value by a preset optimizing algorithm according to the historical wind regime data and a simulation model of the wind driven generator set; the second obtaining is used for obtaining the wind direction of the position wherethe wind driven generator set is located at and the position of a cabin of the wind driven generator set in real time; the difference value determining unit is used for determining the difference value between the wind direction and the position of the cabin; and the yaw control unit is used for controlling the yaw of the wind driven generator set when the difference value is greater than the yawerror angle threshold value and the duration exceeds the time delay threshold value. The equipment is an offline optimizing manner, so that the equipment is capable of adapting to more complicated wind field condition, flexible in utilization, strong in versatility and good in expandability.

Description

technical field [0001] The invention relates to the field of control of wind power generators. More specifically, it relates to a yaw control device of a wind power generating set. Background technique [0002] The active yaw of the wind turbine is that the yaw controller controls the yaw action according to the output signal of the wind direction sensor and the yaw control strategy. For example, when the error between the wind direction and the position of the nacelle exceeds the set allowable range, the yaw controller will issue a yaw command to control the yaw motor to drive the yaw ring gear to perform a yaw correction action so that the nacelle faces the wind accurately. [0003] The existing yaw control strategy is relatively simple and not widely applicable. Contents of the invention [0004] The object of the present invention is to provide a yaw control device and method for a wind power generating set, so as to solve the problem that the existing yaw control st...
