Based on the relevant requirements of IEC62116 "Anti-islanding test method for inverters for photovoltaic well network systems", grid-connected inverter products must strictly undergo factory tests and type tests. Shiying Technology has developed an anti-islanding detection platform for the test requirements of anti-islanding protection tests, which can achieve high-precision type tests and scientific research tests, effectively implement product quality control, and comprehensively and efficiently implement product factory tests and inspections, avoid human detection errors, and meet the requirements of fully automatic detection.

With the implementation of the national carbon neutrality and carbon peak goals, the proportion of new energy sources such as wind and solar energy will become larger and larger, and the power generation of new energy sources such as wind and solar energy will fluctuate greatly due to climate and weather. In addition, due to the influence of various factors on the power grid, local short circuits will occur, or the start and stop of large loads will cause a sudden change in the grid voltage (sudden drop or sudden rise). It is difficult to ensure the transient balance of power generation and consumption.
