China Suppliers: High-Performance SVC MCR Type for Flicker Harmonic and Dynamic Reactive Compensation - Factory Direct
High-Voltage TSC Device
The high-voltage TSC dynamic reactive power compensation device consists of a control system, triggering system, thyristor monitoring system, pulse transformer, capacitor, reactor, protection unit, etc.
The control system detects the reactive power of the power system in real time, automatically determines the capacitor branch that needs to be switched, and then controls the thyristor valve group of the corresponding branch to achieve the switching of the capacitor group. The above process is completely automated, ensuring no impact, surge, or transition when switching capacitors.
TCR Type SVC Device
The TCR type SVC device mainly consists of two parts: TCR (thyristor controlled reactor) and FC (filter capacitor bank). The FC circuit combines filtering function and can provide fixed capacitive reactive power, while the TCR circuit changes the inductive reactive power output of the phase controlled reactor through thyristor control.
Due to the extremely fast dynamic response speed of thyristors, with a response time of less than 10 milliseconds, real-time dynamic compensation of reactive power can be achieved. Especially for three-phase AC arc furnace loads, the voltage fluctuations and flicker generated can be minimized. At the same time, TCR type SVC has phase separation regulation function, which can balance the unbalanced loads of three-phase AC arc furnaces and other loads, and suppress the negative sequence component of the power grid to the minimum.
