Design of self-contained emergency power supply scheme in Jingfu Company
Jingfu Company did not consider the emergency standby power supply during the construction,and there were potential safety hazards.Therefore,in order to prevent and curb the unplanned large-scale power outages in coal mines and ensure the safe lifting of underground staff,it was decided to add self-provided emergency power supply in the mine.According to the actual situation of Jingfu Company,this paper selects the type of self-provided emergency power supply,selects the large-capacity static energy storage device EPS as the self-provided emergency power supply,and calculates the specifications of the energy storage device and the arrangement of related systems according to the information such as the required load.The practice shows that the designed 7.15 MW/10 kV step-up integrated unit and 8.08 MWh energy storage battery system run well,which can ensure the normal operation of Jingfu company's important underground power load under the condition of sudden power failure,achieve the expected purpose,and ensure the safe and efficient production of Jingfu company.
