Abstract

The invention discloses a wind generator set electric control cabinet and a decondensation control method thereof. The method comprises the following steps: obtaining power-off time difference of an electric control cabinet and temperature value in the electric control cabinet after the power-on initialization of an electric control system is completed; judging whether to carry out decondensation heating control according to the obtained power-off time difference of the electric control cabinet and the temperature value in the electric control cabinet; determining the decondensation heating time of the electric control cabinet if the decondensation heating control is carried out; and controlling a heater in the electric control cabinet to continuously heat according to the determined decondensation heating time of the electric control cabinet. Through the wind generator set electric control cabinet and the decondensation control method thereof, the problem that devices in the electric control cabinet are short-circuited after the electric control cabinet is powered on because of condensation which is easily generated when the electric control cabinet of the wind generator set such as offshore wind power and the like is powered off in high-temperature and high-humidity environment can be solved; and the cost of an electric control system is not increased.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an electric control cabinet of a wind power generating set and a decondensation control method thereof. Background technique [0002] The operating environment of wind turbines is special, and the natural environment such as air humidity has a major impact on the stability of the system. For the wind power pitch system operating in areas with relatively high air humidity, especially in coastal areas, the pitch system cabinet is very easy to change day and night. Condensation is formed during the alternating process, and electrical equipment has strict requirements on insulation. In an environment with high humidity, the insulation performance is greatly reduced. Therefore, the operation of pitch electrical equipment in this environment has a large performance risk. [0003] Most of the existing pitch systems do not take measures to deal with the high humidity in th...
