Problems solved by technology

[0003] In the existing technology, the power control in wind power generation is often not comprehensive, and it is only to modify the structural nature of a certain link, or to dynamically adjust the output power of the wind turbine, so that the conversion rate of the wind turbine is not high. Very high, it is difficult to make full use of wind energy

Abstract

The invention discloses a power control method applied to a wind generating set, and relates to the technical field of wind power generation. The power control method is used for adjusting and controlling three aspects of the wind generating set, and the three aspects comprise variable pitch control over the wind generating set, yaw control over the wind generating set and generator parameter control over the wind generating set; in variable pitch control over the wind generating set, the angle of blades of a variable pitch generator can be adjusted in the operation process; in yaw control over the wind generating set, a yaw control system is used for tracking changes of the wind direction; and in generator parameter control over the wind generating set, the power of the generator is adjusted. According to the power control method applied to the wind generating set, by aiming at different wind powers, the flexibility of a transmission system of the wind generating set is improved, parameter information of the generator is analyzed and controlled, an optimal power curve is tracked, and the wind generating set has high wind energy conversion efficiency.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a power control method applied to a wind power generating set. Background technique [0002] The principle of wind power technology is to use wind generators to convert wind energy into electrical energy. Nowadays, with the continuous expansion of the application scope of wind power generation technology, wind power generation technology has gradually become more perfect and has been more widely used. The main advantages of using wind power for power generation are: small footprint, sufficient storage capacity, etc. As far as the current situation is concerned, although the cost of wind power generation is slightly lower than that of solar power generation, it is much higher than that of traditional thermal power generation. Therefore, how to control the cost of wind power generation is also an important issue facing the moment. Wind power generation Power control...
