The Development Of The Dynamic Reactive Power Compensation Equipment Used On 3-Phase 3-Wire Imbalance Load

The thyristor switched capacitor(TSC)is the dynamic reactive power compensation equipment using thyristor as No-contact switch and an important part of the SVC technology.The important parts of the TSC are the dynamic reactive power compensation controller and the thyristor trigger circuit.In the paper,the TSC used on 3-Phase 3-Wire load was discussed in detail,the principle of circuit modules was discussed in detail,presented calculating method of each power parameter at the same time.After experiment,the TSC can measure parameters accurately and act rapidly,it matches the dynamic reactive power compensation technology needs.
