Principles:
Lowvoltage reactive power compensation device (TSC/TSF) is thecompensating device based on switching operation of capacitor banksby thyristor. TSC mainly consists of control system,thyristor, capacitors and reactors.,Capacitor banks aredivided into multiple units to realize step control. TSC is able toimplement step regulating in reactive power, accuracy of regulatingdepends on numbers of multiple unit.Low voltage reactive powercompensation device (TSC/TSF) apply delta wiring. Tooptimize effect of reactive power compensating and harmonicfiltering, TSC capacity and branch configuration must be designed,according to reactive power variation and harmonic components fromnonlinear load.
Low voltage reactivepower compensation device introduction:
based onDSP(digital signal processing) control technology and Instantaneouspower control theory, Weisite low voltage reactive powercompensation device (TSC/TSF) with high-speed switching capabilityare designed to support the supply voltage of distribution systemsand to correct the power factor and eliminate the harmonic currentof connected loads. Thyristor zero-crossing switching switches areresistant to mechanical wear, operate without noise, and arecapable of practically transient-free switching, so it is moresafety than contactor switched capacitor banks.
