Research on Corona Loss of UHV AC Double Circuits Test Line on the Same Tower Under Rain
摘要
Abstract
In order to obtain key data of corona loss of UHV AC double circuits transmission line under rain,two methods,namely,double circuits test line and UHV corona cage,were adopted,moreover,the optical fiber data measurement method was applied to monitor rainy corona loss of UHV AC double circuits test line in UHV corona cage,and 8×LGJ-630 bundle conductors' corona loss was measured under artificial rainfall rates of 12mm/h,16mm/h,and 20mm/h.Then the reduced corona loss equivalent calculation method was used based on the test results of corona cage and test line.The corona loss results of corona cage and test line were basically equivalent,and corona loss equivalent error was controlled in ±6.5% range.The research results verify that,the test results of bundle conductors' corona loss in corona cage are consistent with monitoring rainy corona loss of UHV AC double circuits test line,and the reduced corona loss equivalent calculation method is an effective way to convert bundle conductors' rainy corona loss in corona cage into the one of UHV AC line.The research results can provide a reference for UHV AC double circuits transmission line's corona loss evaluation.关键词
