Wind generating set and method and device for controlling power of wind generating set

Abstract

The invention discloses a wind generating set and a method and device for controlling power of the wind generating set. The method includes the steps that the current running environment temperature is compared with the preset environment temperature range; whether the wind generating set is in a normal working state or not is judged; when the current running environment temperature is larger than the rated maximum value in the preset environment temperature range and smaller than the practically-required maximum value in the preset environment temperature range and the wind generating set is in the normal working state, capacity reducing control is conducted on the wind generating set according to the output power, corresponding to the current running environment temperature, in the preset high-temperature capacity reducing control table; and when the current running environment temperature is smaller than the rated maximum value, required by capacity increasing, in the preset environment temperature range and the wind generating set is in the normal working state, capacity increasing control is conducted on the wind generating set according to the output power, corresponding to the current running environment temperature, in the preset low-temperature capacity increasing control table.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wind power generator set, a method and a device for controlling the power of the wind power generator set. Background technique [0002] The wind power industry has developed rapidly in recent years, and its role in energy supply has become more and more significant. Wind power manufacturing enterprises and research institutes are constantly making the use of wind energy more and more effective through technological innovation. As the utilization of wind energy becomes more and more mature, it becomes a research direction to obtain wind energy under any different environmental conditions. [0003] At present, the design operating temperature of wind turbines is in the range of -10 to 40°C, which mainly depends on the temperature tolerance range of various systems and components of wind turbines. Under higher ambient temperature conditions, due to the...

Problems solved by technology

However, due to the high temperature environment of 40°C or even above 40°C in high-temperature areas throughout the year, the simple shutdown of wind turbines due to high temperatures will greatly reduce the energy available for the wind turbines in such areas. Rate

[0005] On the other hand, some wind turbines will also operate in low-temperature areas with relatively low ambient temperature all year round. The heat dissipation of the wind turbines in such areas is better, but the wind turbines in this area are still in the same fixed position as the wind turbines in other areas. The rated power is fully developed, and the performance of each component of the wind turbine in such a low temperature area is not exerted
