Operational State Analysis Software Research On 500kV Transformer Station

In this thesis, the author analyses the deficiency in detecting andcontrolling function of the computer detecting and controlling systemutilized in present transfOrming station.The strategy of design of software onoperation and direction of 5 00kV transformer station is presented.It points out that we can deduce the mathematic analytical formula usingthe current,voltage and power of two terminals of transmission line asinput.On this basis,we do realtime calculation of 500kV transmission line'sparameter.We can also deduce the linear analytical formula of three-windingautotransformer's resistence using its current,voltage and power as input.Thecorresponding software is programmed on this basis.The result of research show that according to the characteristics of 500kVtransformer station,extending the function of detecting and controllingsystem has important practical sense to safe operation of transformer station.
