Calculation and Analysis of Bundle Conductors ＇AC Corona Loss in Corona Cage
摘要
Abstract
In order to establish a calculation model of conductor corona loss in corona cage,AC conductor was simulated by line charges,and charges were mirrored by square section cage walls.Considering the impact of space charges,the effect of conductor surface electric field strength in-homogeneity on corona charge was calculated.Meanwhile,emission,migration,and recombination of charges were simulated,and energy loss of charge movement was calculated.Moreover,corona loss of bundle conductors was measured in the 8 m×8 m square cross section UHV cage,the test voltage was 200~600 kV,and corona loss of bundle conductors 8×LGJ-500/35 was 0~680 W/m.According to experience,the roughness parameter was 0.85,and the corona loss was calculated.The research results show that,charge simulation method can be adopted to establish corona loss calculation model of single conductor,bundle conductors,and the corona loss calculation model can compute the AC composite electric field strength including space charge,reflect the fundamental physics process of conductor corona loss,and simulate and calculate corona cage bundle conductors corona loss.关键词
