Abstract

The invention discloses a power control method and device for a wind turbine generator system. The method comprises the steps of comparing the environment temperature of the environment in which the wind turbine generator system is located with a preset safety boundary temperature; collecting the temperatures of multiple preset components in the wind turbine generator system in real time when theenvironment temperature is higher than the safety boundary temperature; comparing the real-time temperatures of the preset components with temperature threshold values of the corresponding preset components; and limiting the power of the wind turbine generator system based on comparison results of the real-time temperatures and the temperature threshold values and the types of the preset components. According to the power control method and device, the wind turbine generator system can keep working when the temperature is beyond the safety boundary temperature, and maintain high-temperature electricity generation, thereby expanding the safe operation range, and reducing huge loss caused by a shutdown.

Description

technical field [0001] The invention relates to the technical field of wind power generator power control, in particular to a power control method and device for wind power generators. Background technique [0002] With the development of social economy, power resources have become a necessity of people's life. In addition to traditional thermal power generation and hydropower generation, there are also emerging wind power generation and nuclear power generation methods for power generation. Because wind power has the advantages of being clean, renewable, and not damaging the geographical environment, it has attracted widespread attention. [0003] Ambient temperature has a great influence on the power generation of wind turbines. When the ambient temperature is high, the operation of the wind power generating set becomes unstable, and high temperature shutdown events of the wind power generating set often occur. Therefore, at present, the operators of the wind turbines w...
