Communication interruption self-reset control method and device for wind turbines

Abstract

Provided are a communication interruption self-reset control method and device for a wind power generator. The wind turbine includes a pitch controller and a main control controller that are connected in communication, and the communication interruption self-reset control method includes: when the communication between the pitch controller and the main control controller is interrupted, The heartbeat pulse signal, the DP port status of the main control controller, and the CRC check value of the communication data between the pitch controller and the main control controller are detected; according to the detection results, it is determined that the pitch control unit is faulty and / or the main control control unit When no fault occurs, determine whether the communication interruption is a short-term single interruption; when the communication interruption is a short-term single interruption, the automatic reset operation is performed for the communication interruption, so as to realize the pitch controller and main control controller of the wind turbine. The automatic reset of the communication interruption between them ensures the safe operation of the wind turbine, while avoiding frequent startup and shutdown, and at the same time reducing the downtime.

Description

technical field [0001] The present disclosure relates to the technical field of wind power. More specifically, the present disclosure relates to a communication interruption self-reset control method and device for a wind turbine. Background technique [0002] Energy is the main material basis of social economy and human life, and the driving force of social development. However, the reserves of non-renewable energy sources such as oil, coal, and natural gas, which are the main pillars of the world's energy, are decreasing day by day. Every country in the world is developing wind power generation. As a new energy source, wind power generation has formed a mature scale. [0003] Wind turbine is a device that converts wind energy into electrical energy. Wind energy drives the main shaft, gearbox and generator to convert into electrical energy through the impeller, and through grid-connected control, the electrical energy generated by the wind turbine is transmitted to the gri...
