Guizhou Coal Mine 2.5 MW Energy Storage Project: 20 VGID POWER SP125HCPS Units in Parallel, Strengthening the Mine Area's Power Safety Line

At a coal mine plant area in Jinsha County, Bijie, Guizhou, a 2.5 MW energy storage system composed of 20 VGID POWER SP125HCPS microgrid energy storage converters has been put into stable operation.
The project is centered on multi-unit parallel technology, providing efficient and reliable power support for the mine area and making it a benchmark case for energy storage applications in industrial and mining scenarios.

1. Robust Configuration: 20 Units of 125 kW in Parallel, Building a 2.5 MW Large-Capacity System

The project adopts 20 VGID POWER SP125HCPS energy storage converters, each with a rated power of 125 kW, for a total installed capacity of 2.5 MW.

Based on mature multi-unit parallel technology, the system enables multiple units to operate in synchronous coordination, with precise current sharing and excellent circulating current suppression, perfectly matching the mine area's high-power, high-impact power demand.

2. Operating Condition Adaptation: Reliable Assurance Tailored for Coal Mine Scenarios

Coal mine plant areas impose stringent requirements on the stability and safety of power systems, and the SP125HCPS series was optimized specifically from the outset of its design:

High Overload and Unbalance Tolerance: supports 125% long-term overload and 135% short-term overload, and can withstand 100% three-phase unbalance conditions, adapting to the complex load characteristics of the mine area;

Wide Voltage Adaptation: supports a battery voltage range of 680 V-950 V, and can accommodate second-life batteries or dedicated energy storage batteries, improving resource utilization;

High Environmental Adaptability: IP20 protection rating (IP5X for the core control section) + intelligent air cooling, adapting to the mine area's dusty environment and large temperature differences;

3. Value Delivery: Injecting a "Stable Core" into the Mine Area's Power Safety

After the project is put into operation, it will bring multiple benefits to the mine area:

Peak Shaving and Valley Filling, Reducing Electricity Costs: optimizes power usage by leveraging peak-valley electricity price differences, reducing basic electricity fee expenditures;

Emergency Backup Power, Ensuring Production Safety: provides rapid power supply when the mains is interrupted, ensuring continuous operation of key equipment such as ventilation and drainage;
Grid Support, Improving Power Supply Quality: actively participates in voltage and frequency regulation, suppressing power quality issues caused by load fluctuations.

The VGID POWER SP125HCPS series microgrid energy storage converters, with their modular design, high reliability, and excellent parallel capability, provide efficient energy storage solutions for small and medium-sized commercial and industrial, and industrial and mining scenarios.
The successful implementation of this Guizhou coal mine project once again verifies the product's stability and adaptability under complex operating conditions, providing a replicable benchmark solution for the power safety upgrades of more industrial and mining enterprises.
