The invention relates to an integrated grid-connected detection system and detection method of an energy storage power station, which includes a data acquisition unit, a function test unit and a centralized control unit; the data acquisition unit is used to receive the analog signal input by the energy storage system, and then perform corresponding Filtering and converting them into digital signals, and then sending them to the centralized control unit and functional test unit respectively; the centralized control unit is used for GPS time synchronization, and automatically loads or recognizes the manually input data after receiving the digital signal sent by the data acquisition unit. The project parameter N corresponding to the functional test unit automatically loads the test parameters of the corresponding functional test unit, and stores the detection results of the functional test unit. The invention has the characteristics of high integration, convenient operation, high detection efficiency, high degree of automation, and the detection program of each detection item can be automatically loaded after one-time wiring is completed, which avoids the detection of each detection item during the grid-connected detection process of the energy storage system. Finally, it is necessary to manually set the cumbersome process of the detection program.
Description
technical field [0001] The invention belongs to the technical field of new energy and energy storage, and in particular relates to an integrated grid-connected detection system and detection method of an energy storage power station. Background technique [0002] In order to avoid the impact of energy storage system access on the grid in terms of power quality, safe and reliable operation, and to better play the role of energy storage systems, it is necessary to carry out research on key technologies for new energy-oriented energy storage system access grid detection. Conduct in-depth research on detection technologies such as charging and discharging mode switching, power control, voltage regulation capability, charging and discharging characteristics, and power quality of the system, and promote the development of detection technology for energy storage systems connected to the grid. [0003] However, some existing detection devices are not designed specifically for the gr...
