兆瓦级变速恒频风力发电系统控制策略研究
Research on the control strategy of megawatt variable speed constant frequency wind power system
摘要
Abstract
Based on the working principle of the double-fed induction generator (DFIG),a mathematical model of the DFIG in the two-phase synchronous rotation dq coordinate is derived,and a decoupling control method of the active and reactive output power of the variable speed constant frequency (VSCF) doubly-fed wind power system is presented based on the stator flux oriented vector control strategy.Then a double closed loop control system of the rotor-side converter of the DFIG is designed.To verify the correct and valid of the control model,a simulation test is built under MATLAB/Simulink platform,which takes UP77/1500 IIA LT 1.5MW VSCF doubly-fed wind turbine as the research object.The simulation results show that under the proposed vector control strategy,the double-fed wind power system has satisfactory dynamic characteristics.关键词
