The Study Of Parameter Measurement Of Transmission Line Under Operation Based On GPS

The transmission line is one of the main components of the power system, and the parameter measurement of transmission line is of great important. This article has studied the deficiency and shortcoming of various kinds of methods of the parameter measurement of transmission line at present, proposed the measurement under operation on the basis of GPS, researched GPS application way and error that may appear in the power system synchronal sampling, put forward the parameter computing technology based on the information of both sides of transmission line, which solved some problems that exist in the parameter measurement, especially the problem that exist in the zero-sequence parameter measurement of transmission line with mutual inductance. The hardware and software of the measurement equipment have been designed, which based on the GN79 GPS receiver and SCM.
