From the viewpoint of the equivalent circuit, the interaction mechanism of the ECVT measuring error caused by stray capacity and the interphase interference is quantitatively analyzed. The structure finite element calculation model of the condenser divider of ECVT in 220KV power system is built using the finite element software. The distribution stray capacitance matrix for the voltage divider is measured by simulating its static electric field. The parameters of the condenser divider are optimized by using the ECVT mathematical models established. The experiment results show that the measuring accuracy of ECVT is within 0.2 levels with the nominal capacitance of the condenser divider more than 3500pF.

This commitment has involved several technical, regulatory and operational challenges, but perhaps the most critical of these has been the development of a gas system capable of supplying gas to the 21,667 MW new combined cycles built in Spain since 2002, and the required flexibility to complement and, when required, substitute the unpredictable wind power generation, currently around 15,500 MW and increasing steadily. This gas network system is characterized by the lack of underground storage, the role of the Liquefied Natural Gas (LNG), a competitive gas market, and sharp demand rise, mainly due to the boom of the combined cycles that has led to important investments in new infrastructure during the past years. This paper provides an overview of the Spanish gas market and its implications over the Spanish power system.","PeriodicalId":258632,"journal":{"name":"2009 IEEE Power & Energy Society General Meeting","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129498062","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}

In general, a high power IPMSM and its cooling is designed according to its rated power. Depending upon the application, specific power demand (other than rated) may arise to run the same machine at less or more than rated current. One may like to keep the same machine but change its cooling. Modification in machine cooling can compensate for the increase in machine losses due to its current change. The design of such a machine needs special attention because every machine designed for rated current may not be used continuously at current greater than that. In this paper, the operational range of a baseline machine design is presented and analyzed at less as well as more than rated current, using a cross saturated dq model. It is imperative to consider the demagnetization limit of permanent magnets in the analysis of machine operation. Different machine designs are presented and compared for torque-speed profile and efficiency at different current conditions with increased machine cooling. Machine design with increased width of permanent magnets provides more wider operating region at the cost of reduction in its efficiency for higher speeds.","PeriodicalId":258632,"journal":{"name":"2009 IEEE Power & Energy Society General Meeting","volume":"4 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128225953","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}
