Abstract
To solve sampling-data anomalies of smart substations caused by the complex digital sampling circuit links, this paper puts forward a new model transformer protection design method based on regular sampling and GOOSE trip. NPI plugs is used to achieve new sampling circuit and GOOSE information transmission of analog double AD-directly sampling, and coupled with double AD real-time sampling data validation criterion based on sliding data windows, the effectiveness of sampling data is checked. In addition, for UHV transformer inrush current characteristics, it proposes a comprehensive inrush current identification criterion of differential current harmonics blocking each other and discontinuity points opening, the simulation results show that comprehensive inrush current identification criterion can be applied to the new model transformer protection.关键词
