TSC-Series SCR Reactive Power Compensator
OUTLINE：
TSC-series reactive power compensator uses the high-power controllable silicon static switch to actuate the multi-capacitor banks swiftly and in-transitionally conquers the traditional reactive power compensators' defects in mechanical contact's burnout and surge current to the capacitors, compensates effectively and simultaneously. Adopting three-phase independent controlling technique TSC-W series compensator solves the compensating problems in three-phase unbalanced shock fluctuant load. This compensator is initiative, filling the gap in science and technology in China. TSC-reactive power compensator has high respond speed(less than 20ms) with remarkable saving energy and high power factor. Reducing the losses and stabling the load voltage can enlarge the load range. TSC dynamic reactive power compensator is the renewal and renovation equipment in the field of reactive power compensator. In 1999, our TSC product was awarded "The National Fresh Prominent Product", in 2002, was awarded "A-one brand" in the top-10 nationwide surveys.
WORKING PRINCIPLE：
TSC-series dynamic reactive power compensator adopts the intelligent controlling technique, which consists of controller, Bi-directional thyristor, leak resistors, capacitors, reactors and protective elements. Controller is used to do follow-up measurement the power factor and reactive currents of the loads in real-time. Compare with the pre-established amount and dynamically control the number of imputing capacitor banks; ensure to coordinate the power factors with the pre-established power factor. The measuring process can be completed in one period of time (less than 20ms), and the controller ensure the thyristor trigger though zero, and ensure the capacitors without shock, fluctuating currents and transitional process. TSC not only tracks the changing loads rapidly and dynamically, but prevent the traditional reactive power compensator from its intrinsic defects and the damage of the capacitance.
