Abstract

The invention provides a semi-physical inverter controller test platform. A digital model for testing an inverter controller is built on an upper computer, wherein the upper computer is connected withan emulator through an Ethernet port, the emulator is in communication connection with interface equipment through an optical fiber, the interface equipment is in electric signal communication with atested inverter controller through a connecting wire, and is in optical signal communication with the tested inverter controller through the optical fiber. The digital model is used for replacing part of physical modules in a traditional physical platform, the investment cost is effectively reduced, and the simulation precision of actual engineering is improved; an I / O module with good expandability and good compatibility is provided, and the requirement for simultaneous testing of the aborticide equipment can be met; the method has good editability and equipment adaptability, and different detection items of the inverter and even different power electronic components can be tested by modifying a digital model; and offline simulation can be supported, theoretical testing can be carried out when spare part equipment is not connected, and the risk of equipment damage is reduced.

Description

Technical field [0001] The invention relates to a monitoring system for new energy power electronic equipment, in particular to a test platform for a semi-physical inverter controller. Background technique [0002] With the development of distributed power generation technology, micro grids composed of power electronic equipment such as photovoltaic power generation systems, wind power generation systems, energy storage systems, and loads have gradually been widely used. When the microgrid is connected to the distribution network, it needs to coordinate with the distribution network to adjust the grounding, communication, power control, and relay protection. It can be seen that after the micro grid is connected to the distribution network, the distribution network becomes more complicated. Therefore, it is necessary to check the safety, stability, and grid connection characteristics of the microgrid before it is connected. In some places, a mature standard system for microgrid ...
