The hardware structure and extended instructions of a floating vector processor (FVP) which realize simulation speed up are presented. Experimental results of a sparse matrix calculation and a power flow calculation lead to the following results: (1) the sparse matrix calculation, by the FVP is completed about 1.6 times faster than by a conventional array processor; (2) the processing speed of the FVP is ten to fifteen times faster than that of the general purpose supermini- computer Hitachi V90/50 Control Computer on the conditions that the programming style of the programs executed by the FVP is microprogramming fit to the FVP architecture, and the programs executed by the V90/50 are programmed in Fortran with simple optimization; and (3) the speed of the total power flow calculation by the V90/50 with FVP is 2.6 times faster than that by the V90/50 alone.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"48 4 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":"115784440","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}

This new trend, calls for a rational basis for utilities to compute payments for third party producers. This paper investigates two schemes, one based on the system incremental cost (SIC) (System Lambda) and the other based on optimum Busload Incremental Costs (BIC's) defined as the minimum additional operating cost due to a unit magnitude of energy increment at all system buses taken one at a time. We show here that, unlike the SIC, the BIC's provide the true cost of electricity at all system buses under all operating conditions. Hence, these should prove an excellent basis for a unified policy in the tariffication of economy interchanges.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"64 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":"114789706","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}

A menu driven operating system makes the system user-friendly and avoids the tedium of primitive computer graphics and data calls. The students write programs that share memory with the operating system to manipulate acquired data. This allows the user to call system subroutines to control power supplies and acquire data from their programs as well as reach several utilities from the system menu. The system is under continued expansion as resources allow. The system and, more important, the laboratory course that uses the system are well received by the students.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"50 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":"127420049","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 this paper a low order dynamic model is introduced which retains fully detailed and precise representation of the critical components (such as strong backbone lines like EHV or weak tie lines) where the interest is focused and reduces the detail of representation of other parts of the system gradually with their distance from the spotlighted sections where details are needed. The result is a low order and hence very fast computation with not only detailed but also quite precise results for those parts of the system which are critical. This approach is very flexible, it can be used to compute tie line load and frequency swings on an interconnection of areas or static loads on the tie lines of such a system affecting third parties in a power trading situation. It can be used to compute precisely and fast the EHV system loads or any combinations of such elements. The operator is quite free to choose what should be represented in precise detail.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"104 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":"124046610","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 particular, optimal response digital filters, such as Kalman filters, can be implemented on presently available devices. Optimal filters are not yet extensively applied because they appear complex and engineers have not become familiar with their use. This paper presents the basics of the Kalman filtering technique in power systems terminology and illustrates its use for estimating rotating phasors. Sample designs are presented for voltage and current phasor estimation during system transients. A method for including decaying dc and harmonic frequency components in the filter design is also described and sample results are presented.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"942 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":"116431255","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}
