The new environment includes networked microcomputers, minicomputers, and the corporate mainframe, and provides on-line access to employees outside the energy control center and some WPSC customers. In the late 1980s, WPSC was forecasting an EMS computer upgrade or replacement to address both capacity and technology needs. Reasoning that access to diverse computing resources would best position the company to accommodate the uncertain needs of the energy industry in the 1990s, WPSC chose to investigate an in-place migration to a network of computers, able to support heterogeneous hardware and operating systems. The system was developed in a modular fashion, with individual modules being deployed as soon as they were completed. The functional and technical specification was continuously enhanced as operating experience was gained from each operational module. With the migration off the original computers complete, the networked system DEMAXX (distributed energy management architecture with extensive expandability) has exceeded expectations in the areas of: cost, performance, flexibility, and reliability.","PeriodicalId":294493,"journal":{"name":"Proceedings of Power Industry Computer Applications Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122228688","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}

Published historical data were used in the first phase for validation purposes. Sample results illustrating highly accurate fault impedance estimates for various conditions are reported. The second phase uses voltage and current signals generated by the Alternative Transients Program (ATP) and a sample power system for various first-zone, second-zone and third-zone faults. Results of these studies, confirming the stability and computational efficiency of the algorithm, are presented and discussed. In the third phase, a prototype of the relay was developed and tested using real-time fault data generated from physical models of the transmission lines. Oscillographs for these conditions were recorded. Results of these tests indicating high speed relay operation are also discussed. The performance evaluation studies reported in this paper conclusively demonstrate that the new algorithm provides fast and accurate fault impedance estimates for the three-zone protection of transmission lines.","PeriodicalId":294493,"journal":{"name":"Proceedings of Power Industry Computer Applications Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129648849","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}
