  • The paper was based on the 1000pF capacitance coupling generator partial discharge monitoring system used at Ling’aO II, Hongyanhe and Ningde nuclear power stations. The application status of the mainstream wide band generator partial discharge on-line monitoring system at present was introduced. By means of the research of off-line calibration and software-hardware design, the general method of software parametric filtering according to the commissioning and startup practice of recent several newly-built nuclear power turbine generator was obtained. Then lots of real typical partial discharge pattern data from home and board were collected and studied. The induction and summarization of typical fault analysis and location method for the 2D-partial discharge pattern was completed. This paper also supplied a reference and guidance at the area of insulation judging and fault diagnosis for newly-built and on-line unit startup and operation. we have mastered parameter adjustment of local online monitor system of electric motor, high frequency filtering and photograph analysis, process of measured photograph.
