A method for constructing a dynamic equivalent model of a wind farm based on terrain distribution influence

Abstract

A kind of wind farm dynamic equivalent model construction method based on terrain distribution influence belongs to power system optimization operation technical field, the present wind power generation field dynamic equivalent model is constructed to solve the problem that actual power and the difference in operating state caused by complex terrain distribution are not considered, error is larger in the case of complex wind environment of wind farm.It includes: selecting wind turbine of same model parameter in wind power generation field to form wind turbine generator unit, obtaining power variation and variation rate of each wind turbine in wind turbine generator unit;Obtain the relative sensitivity of wind condition change influence of wind turbine, and the relative sensitivity of wind condition change influence is used as representation index to obtain the relationship between transient potential derivative and relative sensitivity;Obtain the equivalent parameter of equivalent unit in wind condition change dynamic process, and construct wind farm dynamic equivalent model according to equivalent parameter.The present application is used for the construction of wind turbine group equivalent model of same parameter.
