Apparatus and method for managing energy storage power station

A method for managing an energy storage power station, comprising:

• using a first main control module to collect battery information of a first priority in an energy storage power station system, and performing protection and control on the energy storage power station system according to the battery information of the first priority;
• the first main control module being communicatively connected with a battery cluster management unit (BCMU);
• using a second main control module to collect battery information of a second priority in the energy storage power station system;
• wherein the first priority is higher than the second priority;
• wherein the second main control module is communicatively connected with the first main control module and the BCMU;
• and
• transmitting, by the second main control module, the battery information of the second priority to the first main control module, and managing, by the first main control module, the battery information of the first priority and the battery information of the second priority in a unified manner, wherein the battery information of the first priority is transmitted to the first main control module through a first CAN channel, and the battery information of the second priority is transmitted to the second main control module through a second CAN channel;
• wherein the second CAN channel includes at least two CAN channels for parallel transmission, and different second CAN channels correspond to different battery management units, and are used to transmit the battery information of the second priority of each battery management unit in parallel
• wherein the battery information of the first priority includes summary information of the battery cluster, fault information and protection action information of the battery management unit and the battery cluster management unit;
• and the battery information of the second priority includes battery voltage information, temperature information and balance information;
• wherein the first main control module is an ARM module, connected with the battery cluster management units through the CAN communications;
• wherein the second main control module is an FPGA module, connected with the bus of the first main control module, and connected with the battery cluster management units through the CAN communications;
• and
• wherein the first main control module operably uploads the battery information of the first priority and the battery information of the second priority to an energy management system (EMS) through Ethernet.
