无刷双馈风力发电系统变阻尼无源性控制
Passivity-based control of brushless doubly-fed wind power generation system with flexible damping
摘要
Abstract
As wind speed varies randomly , intermittently and uncertainly in the wind farm , wind turbines maximum power output tracking control can be achieved by regulating rotor speed according to the wind speed .Base on the anal-ysis abc three-phase axis model of brushless doubly-fed generator ( BDFG) , theα-βtwo-phase static axis equations of the winding voltage were derived , and the Euler-Lagrange model of BDFG was constructed .The passivity of the elec-trical subsystem and mechanical subsystem of BDFG were analyzed from the energy viewpoint .The passivity-based controller was designed to regulate the speed of BDFG .The flexible damping was added into the controller to improve the system dynamic response and reduce the interference from parameter variations in control system .Modeling on Matlab/Simulink platform and contrasting with vector control and constant damping , and the simulation results show that passivity-based controller with flexible damping could faster track the desired value of speed and have better ro -bustness and dynamic performance .关键词
