Error Intensive Monitoring and Controllable Emergency Control System for Power Management System and Battery Management System

摘要

The present invention determines whether there is an abnormality by performing independent monitoring and control of the data of the power conversion system and the battery management system among the facilities constituting the energy storage device through communication, and controlling the facility in an emergency situation through rapid response. It relates to an emergency control system capable of intensive monitoring and control of abnormalities in the power conversion system and battery management system to prevent the occurrence of fire in the energy storage device. A power management system 20 for storing power of the grid power grid in a battery or controlling the power of the battery to be supplied to the grid power grid; A battery management system 30 that manages a battery for storing power supplied from the grid power grid and performs data communication with the power management system 20; A power conversion system 40 that converts power stored in the battery to AC/DC for charging, or converts the power stored in the battery to DC/AC and supplies it to a grid power grid or a load, and performs data communication with the power management system 20; An energy management system 50 for managing energy by controlling each system through data communication with the power management system 20; And a power meter 60 and other equipment 70; as an emergency control system provided in the energy storage device, the connection between the existing power management system 20 and the battery management system 30 and the power conversion system 40 By using a port separate from the communication port to be used, only the abnormal data of the battery management system 30 and the power conversion system 40 are transmitted, and each facility is controlled to determine whether there is a failure of each facility and to prevent a fire, and the battery It is characterized by consisting of a failure monitoring and control interface 10 that performs independent monitoring and control through data communication between the management system 30 and the power conversion system 30.
