UPQC Technical Parameters
- Voltage Sag Compensation Parameters: Under rated power, the device requires a compensation time of no less than 3s, the minimum residual voltage that can be protected is 0V (0% Un), the response time from voltage fluctuation occurrence to protection activation is ≤1ms, and the output voltage during inverter protection is rated voltage 0.4KV (100% Un).
- Voltage Swell Compensation Parameters: Under rated power, the grid voltage residual of 130% is reduced to 100% grid voltage, capable of continuous long-term operation.
- Features harmonic filtering and automatic power factor compensation. When the mains voltage is normal, the mains supply powers the load through a thyristor; when the mains voltage exceeds the set value, the thyristor disconnects, and the inverter draws energy from the supercapacitor to supply the load with a standard sine AC voltage, with the entire process not exceeding 1ms.
- The comprehensive power quality management device is mainly composed of power electronic components, realizing the switching between supercapacitor energy storage power supply and mains power supply. It can quickly compensate for voltage sags, swells, fluctuations, and other issues in the supply voltage, featuring automatic voltage stabilization.
- Input Voltage Range: -20%~+20%.
- Overall Response Time (from voltage dip occurrence to recovery to rated voltage): ≤2ms.
- Voltage Unbalance: Under compensation state, load side voltage unbalance <4%.
- Output Current Distortion Rate: ≤3% (under linear load conditions).
- Output Current Accuracy ≤±1%.
- Voltage Distortion Rate (THDu): <2.5% (under linear conditions).
- Frequency Tracking Error: Frequency tracking error less than ±0.2Hz.
- Losses: Device losses in electronic bypass state do not exceed 2% of the rated compensation capacity.
- Maximum Operating Efficiency: ≥99%.
- Voltage Compensation Accuracy: Voltage compensation error less than 1% of the set value.
- Minimum Compensation Interval Time: Minimum compensation interval time less than 5s.
- Short-Circuit Current Withstand Capability: 125% can withstand 10 minutes; 150% can withstand 1 minute; 500% can withstand 1 second; 2000% can withstand 200ms.
- The control system adopts an FPGA multi-core processor architecture, fully utilizing FPGA's hardware parallelism advantages to improve data acquisition and computation speed, solving issues such as poor electromagnetic compatibility and frequent crashes of serial software DSP processing technology.
- Features overload and short-circuit protection functions; the device can automatically operate after the overload or short-circuit fault state in the power supply system disappears.
- The device uses Modbus protocol and has a 485 communication interface to integrate into monitoring systems for viewing alarm information and device status. Users can directly access the device and download related event records.
