The first "wind-solar firewood storage" microgrid of the No. 2 Oil Production Plant of Changqing Oilfield has been put into operation for one month at the Mu 165 well site in the Fanjiachuan operating area. The indicators are normal. This project is the first zero-carbon well site successfully constructed in Changqing Oilfield and is expected to save 10.4 tons of diesel per year.
The "wind, solar and diesel storage" microgrid includes photovoltaics, horizontal axis wind turbines, vertical axis wind turbines, energy storage batteries, and diesel generators. The project is designed in an off-grid mode. In addition to photovoltaic and wind energy, the plant's first energy storage lead-acid battery is also used. Lead-acid batteries have the advantages of low cost and high safety. Scientific research experiments on peak and frequency regulation in microgrids have shown that batteries can be used to generate electricity for more than 24 hours on rainy days. The standby 35kW diesel generator can completely avoid the special situation of being unable to generate electricity during long-term rainy weather and keep the pumping unit in a normally open state.
It is reported that this project is the first new energy project developed and constructed by the Second Oil Production Plant in cooperation with its sister unit Bohai Equipment. It implements the concept of green and low-carbon development and has a good demonstration and leading role.
