Product Overview

IPSVR intelligent line voltage regulator is designed for high/low voltage regulation in LV distribution
grids. Adopting high frequency PWM technology, high-performance control chips, and full-control power electronic components. It uses the most advanced control theory and algorithms to monitor and adjust the line voltage in real-time. The device consists of power unit and bypass unit (Automatic bypass, maintenance bypass), which are connected in series in the power grid, It is easy to install with low renovation costs, high reliability, and also provides functions such as harmonic management,reactive power compensation, and unbalance compensation.

Type Definition

① Company Code
②Product: SVR - Intelligent (Series Connected) Line Voltage Regulator

③Compensation Capacity: kVA

④Voltage Level: kV
⑤S -In Series p-In parallel T-Transformer Coupling

⑥A- Fan Cooling N - Convection

Working Principle

When the grid voltage is within the normal range, the automatic bypass is closed, the power unit is in standby state, the load is directly powered by the grid;
When the grid input voltage is low or fluctuates, the automatic bypass quickly breaks,the inverter compensates a required voltage value, and continues to provide the rated voltage to the load;
When the grid voltage returns to normal voltage range, the automatic bypass closed, the power unit is converted to standby state, and the load is directly powered by the grid;
When the SVR fails or is maintained, the load will automatically switch to the maintenance bypass Q1.the load is directly powered by the grid.

Applications

Undervoltage Lines

Long distribution feeder(>700m);Agricultural and breeding users far away from living areas; Undervoltage caused by high load during peak hours in morning, noon and evening, Undervoltage caused by seasonal electricity peaks such as holidays, spring irrigation period, summer hot time, etc.

Overvoltage Lines Due to Distributed Generation
After distributed generation is connected to the power grid, if it is not properly planned or operated, it may cause local grid overvoltage problems due to excessive power, reversed power fow, or insuficient power grid capacity.
