晶闸管投切滤波器TSF的研究

Research of the Thyristor Switched Filters

分析了晶闸管投切滤波器TSF(Thyristor Switched Filters)其主接线和特点,采用专家控制系统来避免投切振荡,从仿真试验和实际运行的结果来看采用新控制系统后,不仅装置的投入过渡过程大大减小,而且负荷的电流波形总畸变率有了明显地降低,功率因数达到国家要求。仿真和实验结果表明了TSF在改善电能质量方面的有效性和可行性。

TSF （Thyristor Switched Filters） main circuit and characteristics is analyzed. Then expert systems are applied to the control system in order to avoid operation surge. According to the results of simulations experiments and actual run, the transition procession current＇s peak value are cut down greatly with new control system. With the TSF was used, the current total harmonic distortion is obviously reduced, and the power factor met the national requirements. The results of simulations and experiments show that TSF is feasible and effective on improving power quality.
