Overview

Three-phase unbalance regulation device, a new product researched by our company for long time and produced, is installed in the head of distribution line in region, used to lessen the unbalanced current of three phases in the front of installation point of the distribution lines (able to limit the unbalance rate within 5%). This device integrates with reactive power optimization, monitoring running status of the distribution zone and etc. this system adopted the international advanced three-potential level technology, able to raise the voltage, lessen three-phase unbalance rate, improve power factor, reduce power loss and save loss, improve electric quality. The device can run stably free from maintenance.

Features

Compensate the three-phase unbalance current

To perform data acquisition and analyze by controller, drive IGBT to take action, transfer the unbalanced current from large current phase to small current phase, limit the unbalance rate of three phases within 5%.

Compensate the reactive current

To perform data acquisition and analyze by controller, calculate the shortage of reactive power, give response within ms, dynamically compensate the reactive current, to keep the power factor more than 0.98, avoid the voltage drop resulted by reactive current of line, reduce line loss.

Regulate the voltage

Sample the voltage from the compensation point, after analyzed by controller, identify the voltage is within the specified range or not, if not, adjust the output current to keep the phase voltage of each phase within the specified range.

Application

1.For the region that has three-phase unbalance current, also large shortage of reactive power

2.For the region that the load of three-phase is much, load change very frequently.

3.For the region that the voltage fluctuates within -20%~+50% (standard value: 220V/380V)
