Abstract

The present invention provides a method and system for processing communication interruptions of wind power generators, wherein the method includes: the pitch controller receives the generator speed value sent by the main controller through the first communication line; When the second communication line between the pitch controller and the main controller is disconnected, a pitch control command is generated according to the generator speed value, and the pitch control is performed according to the pitch control command. Ensure that when the second communication line between the pitch controller and the main controller has a communication flash, the pitch controller receives the accurate generator speed value and continues to control the pitch, which can ensure communication flash through function, so that the wind turbine will not shut down and the pitch system will not malfunction, which ensures the power generation of the wind turbine, avoids the frequent failure of the wind turbine and stops it, and improves the availability of the wind turbine.

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 ...
