双馈风电机组动力学特性与电力系统动态行为的交互影响分析
Analysis of Interaction Between Dynamics Characteristics of DFIG and Dynamic Behavior of Power System
摘要
Abstract
Wind power generation is currently one of the most effective ways to utilize renewable energy. The impact of the increasing penetration of wind power on power system is becoming more obvious,thus the study on the interaction between the dynamics characteristics of wind power and the dynamic behavior of power system is of significance to en?suring the stable operation of power system. In this paper,based on the complete model of doubly fed induction genera?tor(DFIG),by employing eigenvalue analysis and time-domain simulation analysis,the influences of parameters of DFIG on the dynamic characteristics of power system are studied with an IEEE 4-machine 2-area system as a numerical example,and the influences of parameters of turbine governor(TG)on the system’s dynamic response after the connec?tion of wind power are analyzed;the interaction between DFIG and power system is studied in view of several factors, including the grid connection points and capacity of DFIG,as well as the transmission power of tie line. Results demon?strate that the system’s dynamic response can be improved by adding TG after the connection of DFIG;a proper in?crease in the DFIG’s stator resistance is beneficial to the system stability;the grid connection points of DFIG,the transmission power of tie line,and the output level have varying degrees of influence on the robustness of the system.关键词
