Abstract

The invention discloses a control method, a main controller and a converter controller for a wind generating set; the main controller is in communication connection with the converter controller; themethod comprises the following steps of: generating and sending a first command for controlling the converter network side of the wind generating set to stop working to the converter controller when the main controller determines that the wind generating set reaches a preset shutdown condition; receiving the first command by the converter controller and controling the converter network side to stop working according to the first command. According to the control method, the main controller and the converter controller for the wind generating set provided by the invention, the converter networkside is not always in a working state, so that power consumption can be saved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a control method for a wind power generating set, a main controller and a variable flow controller. Background technique [0002] The states of the wind turbine mainly include: stop state, standby state, start state and power generation operation state. Only when the wind power is relatively sufficient, the wind turbine will be in the state of power generation and connected to the grid for power generation. [0003] However, during the entire operation period of the wind power generating set, there will be quite a long time, and the wind power is not sufficient. The wind turbine is in a shutdown state or a standby state. When the wind power generating set is in a shutdown state or a standby state, not only the wind power generating set cannot generate electric energy, but some subsystems of the wind power generating set consume electricity. Such as variable flow ...
