Yaw control equipment and method of wind generating set

Abstract

The invention provides yaw control equipment and method of a wind generating set. The yaw control equipment comprises a prediction module which is configured to predict current and future feasible yaw action sequences of the wind generating set and predict generating capacity and power consumption generated when the wind generating set executes the feasible yaw action sequences under current and future environmental wind information; the optimal yaw action sequence selection module is configured to select an optimal yaw action sequence from the feasible yaw action sequences by utilizing a model prediction control algorithm according to the generating capacity and the power consumption; and the yaw control strategy determination module is configured to determine a yaw control strategy of the wind generating set based on the optimal yaw action sequence.

Description

technical field [0001] The present disclosure relates to the technical field of wind power generation, and in particular to a yaw control device and method for a wind power generating set. Background technique [0002] The unit yaw control system is composed of yaw motor, yaw reducer, yaw bearing and corresponding sensors (such as wind vane, nacelle position sensor), etc., and is rigidly connected with the nacelle and impeller through the yaw bearing. Usually, after detecting the deviation angle between the wind direction and the position of the nacelle, the control system of the traditional wind turbine sends a control command, starts the yaw motor, and drives the nacelle to yaw in a certain direction through the yaw motor. Make the wind turbine in the wind-facing state to absorb wind energy as much as possible. [0003] However, such a yaw control strategy does not fully take into account the different working conditions of the wind turbine, the distribution of the wind d...
