| Abstract: | This paper advanles a method for VAR compensation using a device of thyistor switch series transformer changing capacitance voltage. The principle of the compensation device is described and power characteristic is analysised. Only a little power passing through thyristor is pointed out, so the less capacity of thyristor is needed. Overvoltage and overcurrent in the proceeding of thyristor switch converted is estimated. Indicate it is possibility for reducing overvoltage and overcurrent. By comparing with TSC, points out the cost of device is less than TSC. The device is suit to high voltage power network. |
