Introduction
Power supply system in mining area is a whole which obtains power from the grid or self-built power stations to provide power for the mining area through transmission, transformation and distribution. It consists of power supply, transmission line and power station. The power supply system in mining area should meet the following requirements: Reliability: First of all, it ensures the necessary reliability of all kinds of users, and strive to make the connection of power supply system simple, so as to improve the safety of power supply; Flexibility: Flexible operation, safe operation, convenient maintenance and easy development; Economy: Less investment, less land occupation and low operation cost
There are mainly two types of power supply in the mining area which are internal power supply and external power supply.
The production and construction of mining area mainly relies on external power supply, which is obtained from the nearby regional substation with conditional supply. Internal power supply refers to the power station provided by coal or other related industry department.
Each mining area should have at least two power sources. Two power sources can be interpreted as two independent power stations (or substations) or fed from different bus sections of a power station (or substation). When any power source fails to supply power, the remaining power supply should still be able to bear all the load of the mining area. If the mining area is far away from the power system, it is difficult to introduce external power supply or only one power supply can be obtained from the power system, then internal power supply is needed.
CHINT Group is capable of building its own power station at home and abroad. The mining areas are generally located in remote areas far away from the city. A reliable internal power supply is necessary and CHINT Group has mature experience in this aspect.
