When compensating devices are switched by vacuum switches, if they are switched on group, the inrush current can be controlled by inserting suitable current-restrained reactance in-series. Since the restriking overvoltage is pertinent to the capacity of compensating devices and the time of restriking and igniting, the overvoltage can be restrained by arresters with asterism connection at the entrance of the capacitors. Although switching capacitance devices will bring up high interception cross overvoltage, the metal-oxide arrester can limit this overvoltage in the system designed in the thesis, and naturally the compensating devices can operate normally.

The objective of design optimization for the current loop is to maximize the cross-over frequency. The results show the stability is improved and the capability of suppressing the switching noise is far better than the original. The objective of design optimization for the voltage loop is to minimize the gain of the line ripple voltage.As a result the bandwidth minishes obviously and optimization design excelles in restraining the ripple.
