Application Details
Product Introduction:
This equipment is used to solve power quality problems such as voltage sags/drags in low-voltage distribution networks (single-phase/three-phase). It primarily targets low voltage issues in remote rural areas and grid overvoltages caused by unauthorized residential photovoltaic power generation. Traditional grid upgrades are costly and time-consuming. This equipment can effectively restore normal voltage for users in such scenarios and simultaneously resolve power quality issues such as harmonics, reactive power, and power imbalances within a safety margin.
This equipment boasts advantages such as strong resistance to grid disturbances, high compensation accuracy, fast dynamic response, and strong scalability. It can quickly provide standardized power supply to users during distribution network voltage fluctuations and reduce distribution area losses through multi-energy coordinated control technology, thereby improving the economic efficiency of grid operation.

Low-Voltage Demonstration Project in one county.
This project installed a single-phase 25kW flexible power quality control device. During peak hours, the grid voltage dropped as low as 167.3V. After the device was installed, the voltage on the user side was effectively increased to 225.9V, significantly improving power quality and ensuring user safety.
This project serves 8 households. During the peak electricity consumption period in the summer of 2024, evening electricity consumption was particularly high.
