Abstract

The invention provides a wind turbine generator control method, a wind turbine generator control device and a wind turbine generator control system. The method comprises the following steps of obtaining a detected low-temperature operation parameter; judging whether a low-temperature operation condition is met or not according to the detected low-temperature operation parameter; when judging that the low-temperature operation condition is met according to the detected low-temperature operation parameter, starting a low-temperature operation mode, wherein the low-temperature operation mode comprises the step of adjusting a blade of a wind turbine generator to be in a windward rotation state; and when judging that the low-temperature operation condition is not met according to the detected low-temperature operation parameter, starting a normal-temperature operation mode. When the low-temperature operation parameter meets the low-temperature operation condition by judgment, the low-temperature operation mode is started to adjust the blade of the wind turbine generator to be in the windward rotation state, so that the wind turbine generator is idle; and all parts of the wind turbine generator are rapidly heated by heat generated by mechanical rotation, the starting time of the wind turbine generator is shortened and the power generation efficiency is improved.

Description

technical field [0001] The present invention relates to automatic control technology, in particular to a wind turbine control method, device and system. Background technique [0002] A wind turbine is a device that converts wind energy into mechanical energy and then into electrical energy by turning the impeller against the wind to drive the generator to rotate. The motor, gearbox and other rotating parts in the wind turbine need to be lubricated to reduce wear. A sufficient amount of lubricating oil can ensure effective lubrication of the rotating parts and ensure the stable operation of the wind turbine. Therefore, during the operation of the wind turbine, lubricate The detection of oil quantity is very necessary. [0003] The wind turbine needs to detect the liquid level of the lubricating oil before starting. For example, a switch liquid level sensor is used to detect the liquid level of the gear oil, and the liquid level signal is transmitted to the controller of the ...
