Power control method of multi-type wind turbine hybrid wind power farm

Abstract

The invention provides a power control method of a multi-type wind turbine hybrid wind power farm. The control method comprises the following steps that firstly, the running parameters of the whole wind power farm and the running parameters of various types of wind turbines are obtained; secondly, according to the running parameters of the whole wind power farm and the running parameters of various types of wind turbines, the adjusting parameter of each type of wind turbines is set; thirdly, according to the running parameters of the wind turbines, the adjusting priorities of all types of windturbines are arranged; fourthly, it is judged whether the difference between the real-time active power value of the wind power farm and a preset target active power value is smaller than a reasonable error range value or not; fifthly, according to the sequence of the adjusting priorities of the wind turbines and the set adjusting parameters of all types of wind turbines, the active power of eachtype of wind turbines is adjusted, and finally the first step is executed. By means of the control method, the hybrid multi-type wind turbines in the wind power farm can be cooperatively controlled,so that the output power of the whole wind power farm meets the grid-connected requirements of the wind power farm.

Description

technical field [0001] The invention relates to the technical field of wind turbines, in particular to a method for controlling the power of a multi-model wind turbine mixed wind farm. Background technique [0002] At present, most domestic wind farms are equipped with field-level energy management platform systems, which have basic power control functions, including active power control and reactive power regulation. The performance indicators are designed in accordance with relevant national standards and optimized with reference to the grid-connected guidelines of regional power grids. Most of the products are mainly developed for the function of a single model, with the whole field as the adjustment unit, and the performance index and adjustment method of the single wind turbine unit have not been considered and designed too much. In the past, there were multiple models coexisting in individual wind farms, which could be different models of the same company or products ...
