摘要
基波阻抗和触发角的关系是可控串补(TCSC)触发控制的关键所在。文章对考虑电抗器支路电阻影响时的TCSC触发特性进行了深入研究,给出了线路电流同步时的触发角和基波阻抗的关系曲线,并运用数字仿真手段验证了该曲线的合理性。文章还根据动模实验的实测数据推导出电抗器支路的实际品质因数,基于该品质因数的仿真结果和动模实验结果比较相符。最后根据前述关系曲线进行了触发仿真,开环调节的结果比较令人满意,进一步证实了该曲线的正确性。
The relation of the impedance of fundamental frequency and the firing angle is the key factor in firing control of TCSC. Considering the influence of resistance in reactor branch, the firing characteristics of TCSC is researched in detail, the relation curve between the firing angle, which is synchronized with line current, and the fundamental frequency impedance is given and the reasonableness of the given curve is verified by digital simulation. The practical quality factor of the reactor branch is deduced according to measured data of dynamic analogue experiment and the simulation result based on this quality factor fully coincides with the result of dynamic analogue experiment. At last, on the basis of the presented relation curve, the simulation of firing is carried out and the result of open-loop regulation is satisfying.
