The Design Of Pulse Power Source For Substation Grounding Measurement System

In this thesis ,aiming at the system of electricity performance analysis and faultdiagnosis in the grounding grid of substation , a pulse source is designed .Based onelectical and electron technology ,the structure of the source and parts' parameterare designed or calculated .At the end ,we designed the model machine.By emulation and model's debugging in laboratory, the model machine canwork in low frequency and high frequency .We carried on an experiment thatmeasuring ground electric potential of a grounding grid by the pulse source in northchina electric university .The data from this measurement is consistent with theresult of grid analysis .By high voltage and high power ,the pulse source also can beapplied for the measurement of soil resistivity.
