Research and realization of CurrentCollection in Digital Substation

摘要：

With the development of network and digitalization,the digital substation has become a hot research for people. This paper introduces the research and realization for acquisition the current signal in substation based on Rogowski coils,describes system composition and working principle,designs the hardware circuit of high voltage side,and specifies the selection of each device. The paper also gives main flow chart of low voltage side signal processing.Making a Rogowski coils,which makes a special design,and is given wiring diagram for test.Experiment results show that,the Rogowski coils have good linearity and less measurement error,can meet the current acquisition in substation.

关键词： digital substation acquisition system hardware circuit design Rogowski coil.
