The eigenvalues of the system are obtained and classified. The modes which play the most Important role in the system dynamics are identified and related to the system control loops. The effects of the nonlinearities are assessed by their position in the control loops. It is shown that the adverse effects of the nonlinearities are pronounced when the linear model at operating point, has lightly damped critical modes. The effects of the nonlinearities can be minimized by increasing the damping of these modes using methods outlined in the paper.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"24 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116556043","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}

The new technique uses successive reflections generated by faults. Using a differentiator and smoother the slopes of the transients are computed. Furthermore, the best estimated peaks of the slopes for the first two consecutive transients are obtained. The time interval between these two peaks is proportional to the fault location. The new technique is referred to as simple passive reflectometer (SPR). Field data obtained at the Celilo converter station of the Pacific HVDC Intertie (see the companion paper [1]) are used to evaluate the SPR. The agreement with a two-ended system is within one mile over the length of the 850-mile Pacific HVDC Intertie transmission line.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115894858","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}

The increasing complexity of the power network, the sophistication of the computerized control centers, and the operation of the system closer to its limits, have focussed attention on the effectiveness of this training. It has become obvious that the training curriculum must be carefully designed to meet all the objectives of trainee performance. In this paper, a step-by-step method to develop training curricula using the instructional systems development approach is presented. This approach, developed principally in the U.S. Department of Defense, has been successfully used by NASA, the airlines and other industrial sectors. The experience in using this method to develop a training curriculum for the Arizona Public Service Co. is described.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122593694","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}

The simulation results show that overvoltages could reach 2000 kV, while the maximum breaking current is as low as 5 kA rms. Since these overvoltage values far exceed the IEC specifications (1500 kV), direct and synthetic out-of-phase interrupting tests were performed on two types of breaker: a conventional air-blast circuit breaker of the type already in service and a modern improved design of the same type. The aim of the test program was to qualify high-voltage circuit breakers for the James Bay power system. The paper focuses on the analysis of the test results and deals especially with the decrease in dielectric strength of the breaker with the time that elapses after current interruption.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134615053","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}
