Product Description
Thyristor Switched Capacitor Banks---Tsc/Tsf
Introduction:
Based on DSP control technology and Instantaneous power control theory, Wanlida thyristor switched capacitor banks (TSC/TSF) with high-speed switching capability are designed to support the supply voltage of distribution systems and to correct the power factor and eliminate the harmonic current of connected loads.
Thyristor zero-crossing switching switches are resistant to mechanical wear, operate without noise, and are capable of practically transient-free switching, so it is more safety than contactor switched capacitor banks.
Functions:
Improve power factor
Stabilize busbar voltage and suppress subsynchronous resonance
Eliminate harmonic current
Decrease grid loss
Optimize reactive power
Increase transformer loading capacity
Principles:
Thyristor switched capacitor banks is the compensating device based on switching operation of capacitor banks by thyristor. TSC mainly consists of control system, thyristor, capacitors and reactors. Capacitor banks are divided into multiple units to realize step control. TSC is able to implement step regulating in reactive power, accuracy of regulating depends on numbers of multiple unit.
Thyristor switched capacitor banks (TSC/TSF) apply delta wiring. To optimize effect of reactive power compensating and harmonic filtering, TSC capacity and branch configuration must be designed according to reactive power variation and harmonic components from nonlinear load.
