[Abstract]:The purpose of this paper is to develop a set of monitoring and control software for energy storage power station, to process and analyze the internal data in time, and to realize the monitoring, management, control and dispatch of the energy storage power station. And real-time alarm. The system is based on lithium-ion battery storage equipment and consists of 294 container battery modules. The single battery module is managed by XMC4500 controller and consists of 18650 lithium ion batteries with seven layers. The output voltage is 600V and the energy can reach 2.2 MWh. The central control host obtains the basic information of battery module and the working environment state information of storage power station through Ethernet communication, and processes and analyzes the data, intelligently manages and controls the charge and discharge of battery module. The central control host has a visual interactive interface to update and display the status of the energy storage power station in real time, and the central control host records and stores the status data of the energy storage power station, the alarm data, the operation information of the staff and so on, in the operation process. For calling, querying. The main contents of this paper are as follows: (1) introduce the development of the energy storage power station system at home and abroad, introduce the related technology and typical structure of the energy storage power station monitoring system, (2) analyze the actual requirement of the monitoring and control software of the energy storage power station, design the network communication structure, Make the software development plan; (3) according to the software demand, carry on the design to the software overall frame, divide the software function structure meticulously, design the multithread, solve the problem of thread synchronization concretely, design and realize the interactive interface, network communication, business logic, etc. This paper also designs the discharge control scheduling algorithm of energy storage power station. (4) the communication mode and transmission mode between the central main control system and the lower controller are introduced. The communication protocol between the central master control system and the lower controller is designed in detail. Combining with the application, the format of the function code and the parameters are designed, and the error code is explained. (5) the characteristics of the internal data information of the energy storage power station are analyzed in detail, and the entity is abstracted. Establish entity contact model, analyze the basic attributes of entity object, establish the database application system of energy storage power station; (6) analyze the function characteristics, data characteristics, communication characteristics of the controller in the inner working environment of the box, and put forward the test requirements. Design test methods, build test platform, write test cases, process and analyze test data, and summarize the test. As the brain of the energy storage power station system, the monitoring and control software of the energy storage power station is of great significance for the intelligent management and safe and reliable operation of the energy storage power station. At present, the software has entered the stage of practical adjustment, which is the key link of the whole system test of the energy storage power station.
