The experimental circuit of the 1100kV GIS is simulated, and according to various computing resistance formulas of spark channels, the spark generated by disconnecting switch operation is modeled. The simulated voltage waveforms of the load side are compared with the measurement results. The simulated VFTO is obtained when different disconnecting switch spark models are adopted, with low-frequency oscillations of 200 kHz and 6 MHz, high-frequency of 36 MHz and 56 MHz, and the frequency range is basically consistent with the experimental results. The circuit oscillation frequency is mainly the same compared to different high-frequency decay rate with different spark models. The comparison shows that the simulated voltage waveforms of the load side match the experimental data better than others when Kushner model is adopted. However, the high-frequency attenuation rate of the simulated voltage at the load side is slower than that of the measuring voltage when Kushner model is used. Therefore, further developments in Kushner model are needed in order to reproduce with better accuracy the dynamic behavior of the disconnecting switch spark resistance.","PeriodicalId":379448,"journal":{"name":"2011 1st International Conference on Electric Power Equipment - Switching Technology","volume":"54 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121009497","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}

One class of custom power devices is the series-connected device (SC), such as dynamic voltage restorer (DVR) and series active power filter (SAPF). Recently, downstream fault limiting function of series custom power devices have been proposed and integrated in some literatures as an add-on feature, which can limit the flow of large line currents, and therefore restore the point of common coupling (PCC) voltage as well as protect the series custom power devices themselves. Though it sounds straightforward, there are many difficulties in specific implementation, such as it requires a 100% voltage compensation capacity and very quick dynamic control in some existing proposals. So the feasibility and performance of these methods should be carefully examined. But till now there is no literature available to clarify these problems. In this paper, advantages and disadvantages of existing measures are firstly presented and then new methods are proposed to further improve the feasibility and performance. Detailed analysis is presented and conclusions are given.","PeriodicalId":379448,"journal":{"name":"2011 1st International Conference on Electric Power Equipment - Switching Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133784000","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}

SF6 is also one of the strongest greenhouse gases. Due to equipment maintenance and retirement, SF6 gas leakage and emission from electric equipments is unavoidable. Aiming at developing a low carbon power system, SF6usage and leakage should be estimated. This paper reviews and analyzes the ways by which SF6 gas could leak into the atmosphere. On this basis, a model for estimating the amount of SF6emission by electric equipments is presented. Based on the practical data from Guangdong provincial power system, SF6 emission is compared at the value of equivalent carbon dioxide with generation side CO2 emission. Moreover, future SF6 emission is estimated based on Guangdong power system planning scheme. The proposed methodology is helpful to identify the contribution of Greenhouse Gas emission from diffident parts in power system. Useful suggestions for future work about SF6 management are discussed.","PeriodicalId":379448,"journal":{"name":"2011 1st International Conference on Electric Power Equipment - Switching Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134373066","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}
