Research And Implementation Of Electronic Current Transducer Based On IEC61850

In the coming decades, the new type digital transducer based on air coil is expected to be more widely used in substation automation system than traditional current transformer, for its unparalleled superiority such as linear characteristic. This paper goes into the details of the digital part design of this kind of transducer, on which there are already several good published IEEE standards such as IEC60044-8 and IEC61850. The main content of this dissertation includes the following parts:Chapter1: makes a thorough investigation about electronic current transducer based on air coil.Chapter2: describes the modeling of current transducer defined in IEC61850.Chapter3: explains the mapping of current transducer information model.Chapter4: introduces the realization of this electronic device.Xu Libao(electric power system and automation) Directed by Prof. Chen Gangjie...
