Problems solved by technology

[0002] In my country, Class I and Class II wind energy resource areas have relatively good resources, and the wind speed can often reach about 30m / s during high wind periods. Cut out the wind speed, stop protection in case of strong wind, the fan is always in the shutdown state in the wind speed range of 25m / s ~ 30m / s, and cannot fully utilize the resources of the strong wind, but with the continuous improvement of the technology research and development level of domestic fan machine manufacturers, the fan It is completely possible to realize safe operation under greater wind speed

Abstract

The invention provides a controlling method for improving strong wind generating capacity of wind turbines. According to power management given output values, the wind turbines operate based on the following manners: when the measured average wind speed exceeds 25 meters per second, the given power is reduced at a fixed rate for running; when the wind speed is maintained at 25-30 meters per second, a fan operates at low power; when the average wind speed is greater than 30 meters per second, the fan is stopped for safety; and when the average wind speed is less than 24 meters per second, the given power begins to increase to the power output given power at a fixed rate. The number of available hours of the fan is increased and the amount of generating capacity is enhanced by means of the method.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a control method for increasing wind power generating capacity of wind turbines. Background technique [0002] In my country, Class I and Class II wind energy resource areas have relatively good resources, and the wind speed can often reach about 30m / s during high wind periods. Cut out the wind speed, stop protection in case of strong wind, the fan is always in the shutdown state in the wind speed range of 25m / s~30m / s, and cannot fully utilize the resources of the strong wind, but with the continuous improvement of the technical research and development level of domestic fan manufacturers, Safe operation under greater wind speed can be realized completely. In recent years, the country has continuously adjusted the benchmark on-grid electricity price of onshore wind power and the introduction of the "5.18 New Deal". The wind power industry will develop in the direction of high ...
