A practical tracing method of two parameter stability boundary for voltage stability assessment is proposed. In the traditional tracing method of two parameter bifurcation boundary a second order Hessian matrix of power flow equations has to be computed and factorized, which is a difficulty for on-line application of a large scale power system. By using the single parameter trajectory tracing and the bifurcation point seeking and identification alternately, with the computational expenses of some additional points, the proposed method handles the Jacobin matrix and overcomes this difficulty. The preposition of the proposed method is that the interested part of two parameter stability boundary is composed of both the saddle node bifurcation points and the limit induced bifurcation points, without double saddle node bifurcation points. It is satisfied since the interested part of the boundary is limited. The numerical results about a 3187 bus actual system show that the proposed method is very efficient for on-line application.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122122304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kuffel, Z. Li, B. Freimark, T.

If the test setup is shown to be free of corona by this test, then it is considered that the assembly will be free of corona under operating conditions. This method does not appear in any standards, but is used as a generally accepted test method. In spite of its general acceptance, this test method can give erroneous results. This is due to the fact that the inception of corona occurs at a given electric field gradient rather than a given absolute voltage. Under actual operating conditions, the electric field gradient at the conductor/hardware/insulator assembly is a function of phase spacing, the local geometry, and the applied 3-phase voltage. In order to correctly perform such a test in a laboratory, it is essential that the maximum gradients occurring on the conductors in the field be reproduced in the laboratory test. To address this shortcoming in test procedures, the IEEE PES Transmission and Distribution Committee's Lightning and insulator and corona and field effects working groups are engaged in the development of a guide for the performance of visual corona and RIV testing on insulator assemblies and line hardware.This paper describes the theoretical and experimental background upon which the technical development of the guide is based, and the application of the procedures in the guide as used in testing insulator assemblies and hardware for a new design 6-conductor bundle 765 kV transmission system.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124997293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
