摘要
建立了串联电压控制器的系统分析模型,研究了采用前馈控制和闭环控制策略时变压器的内阻和漏抗对电压补偿特性的影响。在此基础上,提出了串联电压控制器的复合控制策略,不仅能有效地消除变压器内阻和漏抗对电压补偿特性的影响,还能提高其动态响应特性。仿真和实验结果验证了所研究结论的正确性。
The system analysis modei of series voltage controller is built, and the effects of transformer's internai resistance and leakage reactance on its voltage compensation characteristic, when it adopts open-loop and closed-loop control strategies, are investigated, respectively. On the basis of that, a complex control strategy is proposed. The analysis on it shows that using it not only eliminates the effects of the above two factors significantly, but also improves the dynamic response of series voltage controller. The simulation and experiment results test and verify the validity of the conclusions drawn from. this paper.
