MEGAWATT-LEVEL BATTERY ENERGY STORAGE POWER STATION MONITORING SYSTEM AND METHOD THEREFOR

摘要

A megawatt-level battery energy storage power station monitoring system and a method therefor. The system comprises a central monitoring module and local monitoring modules, where two modules employ therebetween a communication network structure having a real-time communication network and a non real-time monotiring communication network running in parallel for communication and connection. The method comprises the following steps: relevant data of a battery energy storage power station is read via communication networks and are stored and managed; a total power demand of the battery energy storage power station is determined; power command values of energy storage substations are determined and are issued to local monitoring modules; power command values of energy storage units in the energy storage substations are calculated and issued to the energy storage units; the power command values, real-time data, and non real-time data of the energy storage units in the local monitoring modules are uploaded to the central monitoring module for unified storage and management. The system and method are capable of satisfying monitoring requirements for clustered-type real-time rapid control of energy storage units and for transmission of a large volume of data, thus ensuring healthy operation of batteries and allowing for improved safety and stability of the energy storage power station.
