Low voltage reactive power compensation controller

This product uses high-performance SCM as the basic hardware, controls the loop with both the reactive power and the power factor, adopts the large-screen LCD monitor, supports compensation of three phases at the same time, compensation of single phase and hybrid compensation, uses the static control and the dynamic control and can realize manual operation and automatic operation, high control precision and no switching oscillation. It can run reliably when the harmonics are severe and the interference is strong in the grid. It has the overvoltage, under-voltage and harmonic out-of-limit protection functions and can display the fault information in Chinese. Configured with RS-485 standard bus interface, it supports Modbus-RTU communication protocol and can control 24 loops of compensation by-pass at most.

Dynamic reactive power compensation hurl-slices switch

With the continuous increase of fast fluctuating load in the power grid, the traditional contactor switching capacitor bank can no longer meet the demand of reactive power compensation. Dynamic reactive power compensation switching switch adopts power electronic device switching, with response speed less than 20ms, which can meet the reactive power compensation demand of fast fluctuating load, and is mainly applied to spot welding machine, rolling mill and other fast fluctuating loads.
