Abstract
The present invention relates to a monitoring and controlling system and method for megawatt level battery energy storage power plant, which includes a central monitoring and controlling module and local monitoring and controlling modules, between the two modules adopts real time and non real time communication parallel network structure to communicate with each other. The central monitoring and controlling module is configured to read the data of the battery energy storage power plant through the communication network, and store and manage the data, determine the total power demand of the battery energy storage power plant, determine all the power demand values of the energy storage substation, and send to all the local monitoring and controlling modules, calculate all the power demand values of the energy storage units, and send to the energy storage units, and then send all the power demand values of the energy storage units, real time and non real time data to the central monitoring and controlling module for unified storage and management. The monitoring system and method meets the requirements of cluster real-time rapid control and thousands of transmission data monitoring, and ensures the healthy operation of the battery to battery energy storage power station more security and stability.
