Wind power generation control method and device for continuous power generation under gale

Abstract

The invention provides a wind power generation control method for continuous power generation under gale, and relates to the technical field of electric power. The method comprises the following steps: when operation parameters of a wind driven generator meet present normal operation conditions, the output power of the wind driven generator is adjusted according to a preset first power curve, so that the wind driven generator is operated by tracking the first power curve; when the wind driven generator is operated by tracking the first power curve, and when the operation parameters of the winddriven generator meet preset first power curve cutaway conditions, the output power of the wind driven generator is adjusted according to a preset second power curve, so that the wind driven generator is operated by tracking the second power curve; and when the wind driven generator is operated by tracking the second power curve, and when the operation parameters of the wind driven generator meetpreset second power curve cutaway conditions, the output power of the wind driven generator is adjusted, so that the wind driven generator is operated by tracking the first power curve. The method can realize continuous power generation of the wind driven generator under the gale.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a wind power generation control method and device for continuous power generation under strong wind. Background technique [0002] Wind power generation technology is a technology that converts wind energy into electrical energy, which can effectively realize the utilization of clean energy wind energy. [0003] The existing wind power generation technology is to use the wind power generation system to convert wind energy into electrical energy. The wind power generator system includes a wind power generator and a control unit. A set of power curves will be stored in the control unit. The relationship between the maximum output power of wind turbines. When the wind speed is between the cut-in wind speed and the cut-out wind speed, the control unit controls the output power of the wind generator to follow the power curve. When the wind speed is greater than the cut-out w...

Problems solved by technology

[0004] However, under strong wind conditions, when the wind speed exceeds the cut-out wind speed and the wind turbine is shut down, the wind speed needs to be reduced to the cut-in recovery wind speed before the wind turbine can resume operation. When the wind speed weakens to less than the cut-out wind speed, but keeps for a long time between the cut-out wind speed and the cut-in recovery wind speed, the wind turbine will also remain shut down, which will cause the wind turbine to shut down for a long time and reduce the wind power generation. Machine availability and power generation

At the same time, under strong wind conditions, the wind speed will often exceed the cut-out wind speed, resulting in frequent start-up and shutdown operations of the wind turbine, which affects the service life of the wind turbine
