Product Features
Overview
Unified power quality control device (AVC) device consists of an AC-DC-AC converter, a circuit breaker QF, a contactor KM, and a compensation transformer. The AC-DC-AC converter employs fully-controlled power electronic devices, enabling bidirectional power flow. The bypass switch is used to switch to the bypass state during maintenance. The contactor KM is used to disconnect or connect the load under the compensation state. The AVC device samples the grid voltage and monitors in real time whether the grid voltage deviates from the set value. Once a deviation is detected, it controls the ACDC-AC converter to output a voltage with the same or opposite polarity as the grid voltage, thereby adjusting the magnitude and polarity of the voltage across the compensation transformer which is connected in series in the main circuit, so as to ensure the stability of the load-side voltage.
Performance characteristics
(1) Real time control of AC-DC-AC converter output voltage to ensure stable load terminal voltage.
(2) Voltage stepless regulation, high regulation accuracy, and uninterrupted regulation process.
(3) The amplitude and speed of the compensation voltage can be controlled, and the output voltage can be controlled by phase separation to adapt to severely unbalanced loads.
(4) The converter adopts modular design, which is easy to maintain and has good scalability.
(5) Equipped with overload protection, software/hardware overcurrent protection, power grid overvoltage/undervoltage protection, over temperature protection, frequency anomaly protection, etc., to improve the reliability of power supply.
(6) It has fault alarm and memory functions, and can store fault records for 30 fault days.There is no limit to the number of records within the storage range.
