Technical Features

FC filtering compensation device

SVC static reactive power compensation device

SVC (Static Var Compensator) is a typical flexible AC transmission device developed on the basis of mechanical switching capacitors and reactors, using high-capacity thyristors instead of mechanical switches. In terms of external characteristics, SVC static reactive power compensation device can be regarded as a controllable capacitive or inductive reactance connected in parallel to the system or load. By quickly changing the reactive power it emits, it has strong reactive power regulation capability, providing dynamic reactive power supply for the power system, improving power factor, and stabilizing system voltage.

SVG Static Var Generator

SVG (Static Var Generator) is a self commutation bridge circuit composed of switchable high-power power electronic devices (such as IGBT), which is connected in parallel to the power grid through a reactor. By appropriately adjusting the amplitude and phase of the AC output voltage of the bridge circuit or directly controlling its AC current, the circuit can absorb or emit reactive current that meets the requirements, achieving the purpose of dynamic reactive power compensation.

Low voltage ride through test device

It can be designed and manufactured according to user needs using fixed or mobile layout methods; By adopting impedance voltage division, various fault simulations of three-phase/two-phase/single-phase can be achieved, and the specific form can be designed and manufactured according to user requirements; It can achieve a drop amplitude from 0% Un to 100% Un. The deviation of the drop amplitude can be less than 5% Un; It can meet the low voltage ride through test requirements for various types of wind turbines with a rated capacity range of 1.5MW-8MW.

Active power filter (APF)

The APF active filtering device injects compensation current into the system through a three-phase parallel converter composed of large capacity IGBT tubes. The compensation current is equal in magnitude to the harmonic current in the load current, opposite in direction, and cancels each other out, achieving the function of filtering out harmonics and ensuring that the final current flowing into the system is a sine wave.

DC ice melting device DEICER

The DC defrosting and SVC device uses high-power power electronic devices to generate DC current, which heats the wire to melt the line icing. The device has the advantages of high reliability and minimal impact on the system, and is suitable for melting ice on large capacity and long-distance power lines The fixed DC defrosting and SVC device can switch between DC defrosting and SVC working modes as needed. When there is no defrosting requirement, the device is converted into a static reactive power compensator through main wiring reconstruction, which improves system stability and transmission capacity, greatly increasing the utilization rate of the device
