分布式电能质量智能优化装置

1, product introduction

      Distributed power quality intelligent optimization device (referred to as UPDS) is suitable for solving the distribution network exists low voltage, three-phase unbalance, low power factor and harmonic problems. The use of advanced synchronous rectification technology, with anti-voltage disturbance ability, accurate compensation, high-speed dynamic response and so on. To the distribution network voltage (120V ~ 260V) fluctuations in the user to provide standard 220V ± 3% voltage.

2, Features


Bidirectional regulation of voltage: When the input voltage of the device is between 120V ~ 260V, the output voltage is stable to 220V ± 3%, the distortion rate is less than 3%. At the same time the device supports single-phase or three-phase connection.

 

Three-phase unbalanced management: Both active and reactive power required by the user side are provided by the DC support capacitor. Based on the synchronous rectification technology, the capacitor obtains active power from the grid without injecting reactive power and unbalanced current into the grid. When the user load is asymmetric, the transformer side is still balanced three-phase output.


Seamless Bypass Switching: The Distributed Power Quality Optimizer incorporates a bypass switch that intelligently determines when power is applied to the grid, switching bypass mode or online mode. Mode switching, the output voltage amplitude, phase and input voltage exactly the same, to achieve no current switching.

 

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, can access the power grid SCADA system, real-time monitoring of power grid voltage, current, power and other state, to achieve the daily maintenance of equipment and management.

 

Expansion: The device has reserved a new energy interface that can accept new energy such as photovoltaic, wind power or biogas power access. The new energy power access can effectively solve the capacity shortage of distribution transformers, ease the peak of power consumption and improve the stability of power distribution.
