    Product introduction

    Unified power quality conditioner UPQC combines modern power electronics technology and automatic control principle technology to achieve dynamic power quality comprehensive management. The series inverter realizes the compensation of the power supply voltage, so that the load obtains a sinusoidal AC voltage; The parallel inverter realizes the compensation of the load current, so that the power supply obtains sinusoidal AC current, and the series inverter and the parallel inverter work together, so as to achieve the load to obtain high-quality sine wave voltage, and the power grid to obtain high-quality sine wave current. Combined improvement of voltage quality (harmonics, amplitude, transients, etc.) and intertransmission of harmful currents in isolated loads.

    Unified power quality conditioner can realize a variety of functions through multi-objective coordinated control:

    (1) Voltage control (voltage sag rise, sag, distortion compensation, etc.) 

    (2) Current control (active dynamic harmonic filtering)

    (3) Power control (active and reactive dynamic compensation)

    (4) Three-phase imbalance compensation

    (5) Stabilize the grid frequency

    Application

    Mainly used in petrochemical, semiconductor, chemical, pharmaceutical, automobile manufacturing, textile and other high-precision industrial fields greatly affected by power quality, as well as industrial and commercial energy storage, microgrid, weak current area power supply and other markets are widely used.

    Technical characteristics

    The Unified power quality conditioner is composed of series inverter, parallel inverter, filter, series transformer, power supply voltage compensation detection, load current compensation detection, and controller. According to the requirements of the compensation amount to issue a control command, so that the series inverter outputs the desired compensation voltage, completes the function of frequency and voltage adjustment, so that the load-side voltage distortion rate does not exceed 2%, the parallel inverter outputs the expected compensation current, so that the grid-side current distortion rate is less than 5%, and the fuzzy control strategy (Fuzzy Control, FC) is adopted, which has strong robustness, especially for nonlinear, time-varying and hysteresis system equipment, with perfect control rules. In the event of an exception, automatic bypass does not affect the continuity and reliability of power supply.
