Research on TSC control strategy based on the average of TCR threephase trigger angles
Due to the continuous development of static reactive compensation device, the coordinated control between different devices becomes more and more important. In this paper, on the basis of the TCR+FC model,a TSC branch as reactive power reserve is added to make up TCR+TSC+FC type SVC. Depending on the relationship between the trigger angles of TCR and the reactive power demand of the system, a TSC control system is designed based on the average of TCR three-phase thyristor trigger angles. Meanwhile, in order to ensure the fast and accurate switching of the TSC capacitors, the triggering control mode of enabling thyristors with positive and negative phase at the same time is also designed when the voltage at both ends of the thyristor crosses zero. The simulation results of PSCAD with an engineering example show that the design scheme is correct and feasible.
