Detection test system for energy storage power station grid connection

Abstract

The invention relates to a detection test system for energy storage power station grid connection. The detection test system comprises an equipment layer and a centralized control layer. The equipment layer comprises an electric energy quality on-line monitoring device, an on-site measuring and controlling device, a relay protection tester and a communication manager. The electric energy quality on-line monitoring device is connected with a communication processor of the centralized control layer through a communication network. The on-site measuring and controlling device and the relay protection tester are connected with the communication manager through a field bus, so that the detection test result is converted into a corresponding data format through the communication manager. The communication manager is connected with the communication processor of the centralized control layer through the communication network and uploads the detection test result to a computer of the centralized control layer. The centralized control layer comprises the communication processor and the computer connected with the communication processor, the computer is used for controlling the detection test process, carrying out data analysis and processing on the detection test result uploaded by the equipment layer and generating a graphic report. The system can carry out a detection test on the grid connection index of an energy storage power station, and is simple in structure, complete in function and good in use effect.

Description

technical field [0001] The invention relates to the technical field of grid-connected detection and test of energy storage power stations, in particular to a grid-connected detection and test system of energy storage power stations. Background technique [0002] The non-renewability of traditional energy has promoted the rapid development of new energy. With the expansion of new energy power generation and grid-connected scale, its impact on the grid and its impact on power quality cannot be ignored. Therefore, energy storage technology has been rapidly developed as an effective method to solve this problem. At the same time, energy storage technology also plays a huge role in the construction of smart grid. In terms of power consumption and transformation, the energy storage system can realize peak shaving and valley filling, delaying the upgrading of high-cost power grids; it can improve the power quality of civil, commercial and industrial power consumption; it can prov...
