[Abstract]:In the field error verification of 1000kV UHV GIS current transformer, due to its long test loop and large impedance, the conventional test methods have difficulty in raising current and complicated operation. Based on the analysis of the structure characteristics of UHV GIS current transformer and many years of field work experience, this paper designs and implements an intelligent verification system for 1000kV UHV GIS current transformer field error, and discusses the composition and implementation scheme of the verification system. The series technology of power electronic power supply and electrical power supply, adaptive reactive power compensation technology and intelligent verification technology are put forward. The software and hardware design method of intelligent power frequency power supply is introduced, and the realization method of multi-combination reactive power compensation device is given. The field verification experiment of 1000kV current transformer at UHV Nanjing Station and Taizhou Station shows that the calibration system can accurately calculate the electrical parameters of the current transformer, compensate reactive power automatically, and automatically realize resonance boost and error calibration. The technical level and working efficiency of field verification are improved.
