Abstract

The invention relates to a circuit system in a wind power generating system, in particular to a yaw circuit system in the wind power generating system. The yaw circuit system comprises a microprocessor for receiving the sample of output voltage of a fan, a wind direction sensor for inputting a wind direction signal into the microprocessor, a wind speed sensor for inputting a wind speed signal into the microprocessor, a yaw motor steering control module for receiving a signal of the microprocessor and controlling a yaw motor to steer, a keyboard module and a display module which are connected with the microprocessor, and a power conversion module which is respectively connected with the wind direction sensor, the wind speed sensor, the microprocessor and the yaw motor steering control module. A yam system can be quickly and stably aligned with the wind direction, so that a wind wheel can acquire the maximum wind energy.

Description

technical field [0001] The invention relates to a circuit system of a wind power generation system, in particular to a yaw circuit system used in a wind power generation system. Background technique [0002] The yaw system is a unique control system for wind turbines. The yaw control system is mainly composed of three parts: yaw measurement, yaw drive transmission part, and cable protection device. The main functions of the yaw system are: 1. Make the nacelle track the changing and stable wind direction; There are various existing yaw mechanisms, but they all have the function of realizing automatic yaw adjustment. However, the existing yaw system, especially the circuit of the yaw system, is insensitive in action and cannot be aligned with the wind direction quickly and stably. Contents of the invention [0003] The purpose of the present invention is to provide a yaw circuit system in a wind power generation system. The present invention can align the yaw system to the...
