Embodiment Construction

[0047] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0048] Embodiment of the method for estimating wind power generation in the present invention

[0049] The wind power generation estimation method of the present invention is as follows: figure 1 As shown, the wind measurement data are firstly counted to obtain the Weibull parameters of the wind speed distribution; then the corresponding Weibull cumulative probability distribution function is determined by using the obtained Weibull parameter, and the corresponding wind speed points are determined according to the Weibull cumulative probability distribution function Distribution probability; then calculate the annual theoretical power generation of the wind farm according to the wind speed-power curve and the distribution probability of each wind speed point; finally estimate the actual power generation of the entire wind farm according to t...

Abstract

The invention relates to a wind power station generating capacity estimation method and system, and belongs to the technical field of wind resource evaluation. According to the invention, a distribution probability of each wind speed point is obtained according to a Weibull parameter of wind speed distribution, and an annual theoretical generating capacity of a wind generation set is obtained by utilizing a wind speed and power curve and the distribution probability of each wind speed point; the whole estimation process is simple, convenient and rapid; the generating capacity of a wind power station can be accurately estimated; and the wind power station generating capacity estimation method and system have very important significance for carrying out primary evaluation on wind energy resources of the wind power station, reducing time cost of developing the wind power station and providing data support for decisions on construction of the wind power station.

Description

technical field [0001] The invention relates to a method and system for estimating the power generation of a wind farm, and belongs to the technical field of wind resource evaluation. Background technique [0002] In recent years, with the rapid development of the wind power industry, Class I, Class II, and even Class III areas with better wind resources have been exhausted. At the same time, due to the rapid development of wind farms and the lag of supporting facilities, the problem of wind power consumption in the "Three North" regions with better wind resources is becoming more and more serious, and the wind abandonment rate remains high. For this reason, the relevant state departments have also stopped the approval of new projects in areas with a high wind curtailment rate, and guided the construction of wind farms from the policy to the southern mountainous wind farms and the central wind speed areas. The construction of wind farms in mountainous or light wind speed ar...
