Abstract

The invention provides a processing method and system for communication flash breakdown of a wind driven generator. The processing method comprises the following steps that a variable-pitch controllerreceives a generator rotating speed value sent by a main controller through a first communication line; when the variable-pitch controller is used for determining that communication flash breakdown is generated on a second communication line between the variable-pitch controller and the main controller, a pitch adjustment control command is generated according to the rotation speed value of the generator, and pitch adjustment control is carried out according to the pitch adjustment control command. According to the processing method and system, when communication flash breakdown is generatedon the second communication line between the variable-pitch controller and the main controller, the variable-pitch controller is ensured to receive the accurate generator rotating speed value, pitch adjustment control is continued so that the communication flash breakdown crossing function can be realized in a guaranteed mode, furthermore, a wind generating set is prevented from being stopped, malfunctions of a variable-pitch system are avoided, the generating capacity of the wind driven generator is guaranteed, the wind driven generator is prevented from being stopped due to frequent failures, and the utilization rate of the wind driven generator is improved.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, in particular to a method and system for processing communication interruption of a wind power generator. Background technique [0002] As a new energy source, wind power generation has been well applied. When the wind turbine is in normal power generation operation, the pitch system needs to track the maximum power. At this time, the pitch angle needs to be opened to the zero position to absorb the maximum wind energy. The pitch system can also control the pitch system to adjust the pitch angle after the main control system performs PID calculation according to the target speed value and the actual speed value after the wind turbine enters the constant speed operation area or power operation area, and then adjusts the pitch Control to achieve the purpose of stabilizing the generator speed. [0003] In the pitch control of the wind turbine pitch system, the main controller ...
