Safety is the top priority of mining, chemical and other enterprises! Power supply safety is not only a part of production safety but also the basis of production safety. When the power grid is cut off, the use of emergency power supply can effectively ensure the power supply of critical loads and avoid safety accidents.
1.project introduction
A coal mine in Northeast China based on the overall situation of building "industry leader", standing in the historical starting point of "100 years of coal mining, output value exceeding 10 billion, entering the province's top 100", always unswervingly take the road of safe and efficient development. In order to comprehensively build a safe, green, intelligent and efficient mine and improve the reliability of power supply, the 6KV high-voltage emergency energy storage system produced by FGI is selected after comprehensive evaluation. The energy storage system is a stationary coal mine emergency power supply and is connected to the system bus through the switch cabinet.
2.System configuration scheme
FGI cascade energy storage system has the advantages of single cluster operation of battery clusters, no circulation between battery clusters, high safety, good economy, single set of large capacity, high efficiency, small footprint, etc. The topology is shown as follows.
3.System advantages
Emergency power supply: provide double circuit external backup power supply, when the power grid is cut off, increase the safeguard measures for mine electricity.
Peak and valley arbitrage: The use of local electricity price difference, through charging and discharging to achieve peak and valley arbitrage, gain benefits.
Reactive power compensation: with reactive power compensation ability, improve power factor, stable voltage.
Four-quadrant operation: with the ability of four-quadrant output, real-time energy transmission and receiving, to ensure the stability of the output voltage, the main fan fast anti-risk control system.
Automated operation: unattended, automated, intelligent operation and maintenance is simple.
Energy saving and environmental protection: environmental protection and pollution-free, in line with the requirements of green mine construction, in line with the development trend of science and technology.
