A Research On The Several Electromagnetic Field Calculation Problems Based On FEPG

Based on the FEPG system of Feijian, the solutions of static electric field, quasi-static electric field and time-harmonic field are researched. Then virtual dielectric constant method is adopted to calculate the electric field distribution with floating electrodes, and equivalent conductance rate method is adopted to calculate the electric field distribution with surface filth or local puncture in the insulator, furthermore the value scope of virtual conductance rate and equivalent conductance rate are discussed and some useful results are got .For the solution of vortex loss of silicon steel sheets concerning current transformer, the H solution has also been put forward rather than traditional A ?(p method in order to reduce calculation load. In addition, based on the developing platform of FEPG, three-dimensional electric field analysis software has been developed, the main interface of which is written in visual C++, while the core calculation procedures are written in visual Fortran.Huang Cheng (Electric power system and automation)Directed by Prof. Wang Zezhong...
