As of December 25, the first "Fengfeng Firewood storage" microgrid of the second Oil production plant of Changqing Oilfield has been put into operation for 1 month in the Mu 165 well site of Fanjiachuan operating area, and all indicators are normal. The project is the first zero-carbon well site successfully built in Changqing Oilfield and is expected to save 10.4 tons of diesel fuel per year.
"Wind fuel storage" microgrid includes photovoltaic, horizontal axis fan, vertical axis fan, energy storage battery, diesel generator. The project is designed in accordance with the off-grid mode, and in addition to photovoltaic and wind energy, it also applies the plant's first energy storage lead-acid battery. Lead-acid batteries have the advantages of low cost and high safety. The research experiment of peaking and frequency modulation in the microgrid shows that the battery can be used to generate electricity for more than 24 hours in rainy days. The standby 35 kW diesel generator can completely avoid the special situation of long-term rainy weather can not generate electricity, and keep the pumping unit normally on.
It is reported that this project is the first time that the second oil production plant has cooperated with its brother Bohai Equipment in the development and construction of new energy projects, which has practiced the concept of green and low-carbon development and has a good demonstration and leading role.
