新型混合无功补偿装置的控制方法

提出以配电静止无功发生器（DSTATCOM）容量上限作为约束条件将无功进行分配,在先求出DSTATCOM补偿容量的前提下求出晶闸管投切并联电容器（TSC）的投入组数,使混合无功补偿装置能够进行精确的补．仿真分析表明,新的控制方法对混合无功补偿装置的控制具有可行性、有效．

New Hybrid Reactive Power Compensation Device Control Method

The hybrid var compensator consists of a group of small-capacity distribution static synchronouscompensator（ DSTATCOM ） and multiple thyristor switched capacitors （TSC） composition. DSTATCOM as a deviceof continuous subsystems, TSC as discrete device subsystems, can be seen in the hybrid var compensator totalcompensation capacity of both the algebraic sum of the respective compensation capacity. This paper presented anew control method to DSTATCOM maximum capacity as a constraint would have var allocated. First find thepremise DSTATCOM compensation capacity then to calculate TSC investment group number, so that the hybrid varcompensator can be accurately compensated. Simulation results show that the new control method for the hybrid varcompensator control has feasibility and effectiveness.
