The starting characteristic of the high-voltage motor is calculated based on the numerical method. In addition, this paper analyses the influence of the load changes on the starting characteristic. Compared with the steady-state characteristic curve, the result is much closer to the practical situation. This method provides more accurate references for the high-voltage motor design and the determination of starting mode.","PeriodicalId":20466,"journal":{"name":"Proceedings of 2011 6th International Forum on Strategic Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77967603","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}

For the present there is not possibility to create the detailed power network models of the trance-national power grids, which could be available for open access, because of the well-known national safety reasons. This paper illustrates the way to overcome partly the barriers for team-work of experts from different countries by the example of EU-Russia power network model.
