Micro-Grid System Application In Green Power Oil Fields

This scheme adopts a microgrid system with a hybrid power supply of wind and solar energy storage and municipal electricity. It can use wind and solar energy to drive the entire oil extraction system, and the municipal electricity serves as a backup unit or supplementary energy source; The system is equipped with an energy storage system, which can achieve power supply for the reciprocating movement of the oil extraction machine and charge and discharge management during the reverse power transmission process. At the same time, the system has a high power factor, wide frequency conversion and speed regulation range, effectively matching the operating stroke frequency and working conditions of the oil extraction machine. At the same time, the energy storage system can provide heating and insulation power supply for the system, achieving significant energy conservation and environmental protection in the oil field to ensure production and increase.

For oil extraction plants with existing municipal power supply systems, the existing system can be retained and photovoltaic modules and small wind turbines can be arranged in an open field for power generation. Wind and solar power generation, direct drive technology, energy storage technology, variable frequency speed regulation technology, and multi unit group control technology of oil extraction motors can be used to significantly reduce system energy consumption pulsation and maximize the utilization of photovoltaic energy. Municipal electricity can complement each other in real-time when necessary, significantly reducing the operating time of municipal electricity, It is estimated that it can reduce the daily energy consumption of the system by 70-80%, save system operating costs, and improve the quality of power grid operation.

Compared with the existing mains power supply system, this scheme has the advantages of multiple power supplies, significantly optimizing the operating conditions of oil extraction machines, reducing oil production costs, and reducing carbon emissions, making the oil extraction system safer, more reliable, and more economical.
