双馈式风电场抑制电网低频振荡的实时数字仿真仪实验
Experiments on Damping the Low Frequency Oscillation of Power Grid by DFIG-based Wind Farm with RTDS
摘要
Abstract
The hybrid power transmission of doubly-fed induction generators(DFIGs)based wind farms and convention?al power stations is one of the main modes adopted by the development and transmission of large-scale wind power in the future. However,the overall stability of this transmission mode is possibly poor. In this paper,the low frequency oscilla?tion in the hybrid transmission mode of conventional power stations and wind farms was analyzed firstly. Secondly ,the feasibility of using wind farms to damp the low frequency oscillation of conventional power stations was analyzed ,and an additional damping control strategy was proposed together with the fabrication of a prototype. Finally ,real-time simu?lation models including a DFIG model,a synchronous generator model and a"Wind fire binding"model were estab?lished by using a real-time digital simulator(RTDS),and they were further tested in coordination with the prototype. Experimental results illustrated that based on the proposed control strategy,the prototype can exert the transient active power adjusting ability from the wind generators themselves to contribute damping for the grid;it can both improve damping and restrain the low frequency oscillation of power grid effectively.关键词
