摘要:
针对小型风力异步发电机机端特性的不稳定,提出了带储能系统的异步发电机稳压稳频控制方法。在直流侧并联铅酸蓄电池系统进行储能,通过控制整流器实现直流侧有功和无功的双向流动。该控制方法包括电压外环和频率内环两个控制环,电压和频率控制器都采用的是PI控制器,用改进的锁相环法实时检测系统的频率变化。为了验证控制方法的有效性,进行了MATLAB/Simulink控制系统仿真和实验。结果表明:采用带储能系统的稳压稳频控制可以提高异步发电机的机端特性,改善独立供电系统的电能质量。
Abstract:
This paper deals with the voltage and frequency controllers of a micro wind asynchronous generator with an energy storage system.The system,along with an energy storage equipment,charges or discharges at its direct current link.The proposed controllers have bidirectionally active and reactive powers flow capability by which it controls the system voltage and frequency with different consumer loads.The control method includes voltage and frequency loops.The voltage and frequency controllers are both PI controllers.The real-time detection system of the frequency variation adopts a PLL improved method.A set of new VF controllers are designed and their performance is simulated in the MATLAB/Simulink and experimented to verify the correctness of the control method.The result shows the control strategy can improve the asynchronous generator port characteristics and the power quality of the system.
