集中式电能质量智能优化装置

1, product introduction

     The centralized power quality intelligent optimization device (BPF) is installed at the head of the transformer to realize the balance of the output power of the three phases of the transformer, compensate the reactive current and harmonic current generated by the distribution line, and improve the carrying capacity of the transformer. Adjust the output of the transformer Voltage, to ensure the quality of power supply.

2, working principle

BPF (Balance Power Filter) adopts advanced three-level circuit topology (low loss, low noise), through the three-phase line asymmetric active power energy exchange and current compensation technology to achieve three Phase power balance, reactive power compensation and harmonic current elimination.

3, Features

Three-phase unbalanced management: three-phase intelligent regulation of active power, to achieve three-phase transformer current balance output; to avoid when the load is unbalanced distribution, resulting in single-phase transformer overload; the same time, three-phase balanced output can effectively reduce transformer losses.

 

Power factor adjustment: Compared with the traditional capacitor compensation, the device real-time tracking high-speed changes in load reactive power, accurate tracking compensation, and can effectively suppress the harmonic voltage and current systems. By adjusting the reactive power, system voltage fluctuations can be reduced.

 

Filter function: Multi-DSP collaborative control, high filtering accuracy, fast response; the target harmonic, the effective filtering capacity of up to 95%, while filtering a variety of harmonics, the maximum can be filtered to the 50th harmonic; Settable harmonic fractional compensation.

 

Modular design: Taking into account the growth of the user load characteristics, the device uses a modular design. Customers can configure the capacity according to different needs, the need for expansion or replacement, the increase or decrease can be easily replaced, thereby reducing duplication of investment.

 

Structural Design: The device supports outdoor pillar installation or indoor installation, the protection grade is IP54, which can be installed on the existing poles or distribution room.

 

Communication system design: Equipment with RS232 / 485 and GPRS interface, access to power system ACADA system, real-time monitoring of power grid voltage, current, power and other state, to achieve the daily maintenance of equipment and management.

 

Extended functions: The device is reserved for the I / O interface, on-load regulator, compensation capacitor bank and other equipment for integrated control.
