Abstract

The invention discloses a platform for testing microgrid converter hardware on a return circuit system. The platform for testing the microgrid converter hardware on the return circuit system comprises a supervisory control computer, a target computer and a platform body for testing the converter hardware on the return circuit system, wherein the supervisory control computer and the target computer are used for the platform body for testing the converter hardware on the return circuit system to achieve simulation of the microgrid converter hardware on the return circuit system. According to the platform for testing the microgrid converter hardware on the return circuit system, a simulation model of a microgrid system replaces an actual microgrid system to be used for testing the performance of a microgrid converter and developing the microgrid converter, the development cycle of the converter is shortened, the development processes of the converter are simplified, development cost of the converter is reduced, automation of testing and developing is achieved, and the application range is wide.

Description

technical field [0001] The invention relates to a micro-grid converter test platform, in particular to a micro-grid converter hardware-in-loop system test platform. technical background [0002] The converter in the power system is a device that converts electrical energy into AC / DC, AC / AC, DC / DC or DC / AC, and the microgrid is based on distributed power generation technology to be close to distributed resources or users Based on small power stations, a small modular and decentralized energy supply network formed by combining end-user power quality management and energy cascade utilization technologies. [0003] With the rapid development of micro-grids, new power electronic equipment, especially the specific application of various converters, play a vital role in energy conversion, and are of great importance to the research, development and testing of converters and their controls. practical significance. [0004] When developing a traditional converter, it is first neces...
