In this light, the knowledge of what caused particular voltage sags can be invaluable in deciding where to spend a limited capital improvement budget. This article describes an integrated system of databases that correlates voltage sags with transmission line faults and any corresponding lightning strikes that caused the fault. By determining the critical locations for susceptibility to lightning-induced faults, remedial measures can be tactically implemented to improve both the lightning protection and the fault performance of the system. In addition, disturbances not caused by lightning can be identified so that other causes can be determined.","PeriodicalId":435675,"journal":{"name":"IEEE Computer Applications in Power","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123771943","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}

However, utilities cannot adapt to changing business conditions without having a flexible information technology (IT) infrastructure as well as information about and complete control of operational systems. While traditionally the business and power system control functions in an electric utility were run more or less separate and apart from each other, such isolation inhibits efficient operation and inhibits high-level, profit-oriented analysis from occurring. What is needed is a framework that enables data to be quickly shared, coalesced, and transformed into usable information. This framework should be robust enough so that, as new situations arise, information can be exchanged and analyzed in ways not previously anticipated. This article discusses utility application and data integration issues and related standards activities. A summary of work going on within the Electric Power Research Institute's (EPRI) Control Center Application Program Interface (CCAPT) task force, the International Electrotechnical Commission (IEC) working groups 13 and 14, and the Utility Domain task force in the Open Management Group (OMG) is provided. EPRI's Common Information Model (CIM) and Message Bus are described with emphasis on how they can be used to create a powerful and flexible enterprise architecture.","PeriodicalId":435675,"journal":{"name":"IEEE Computer Applications in Power","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127774467","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 same system may have to be modeled and solved in many different ways, depending upon the studied event of interest. It has been desirable to have a single software platform from which several power system analysis functions can be easily activated for the same power system. The network under study may go through changes due to switching events, outages of equipment, generators, or loads. Such changes should be recorded only once and recognized by all applications running under this platform. Each application should have easy access to the results produced by any other application. This allows modular development, updating, or replacement of various applications independent of each other. Power Education Toolbox (PET) is such a software package and has been under development at Texas A&M University for several years. The GUI of PET allows users to create one-line diagrams of systems, specify components and simulation parameters, and view output.","PeriodicalId":435675,"journal":{"name":"IEEE Computer Applications in Power","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132537144","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 these customers, it is important that utilities be able to offer complete solutions to meet their needs. Depending on the customer load requirements, standby generation, uninterruptible power supply, or automatic restoration are possible solutions to improve the system reliability. In addition, utilities are becoming increasingly automated to keep up with the demands of the new business environments. As newly reregulated distribution companies emerge, it is likely that reliability indexes will be one of the key factors for regulators to examine to determine the overall performance of the distribution company. Thus, drivers for distribution automation include: remote control and restoration; targeted regions or customers for improved reliability and operation; performance based rates (PBR); and safety issues for circuit isolation. Whatever the driver for feeder automation, several key issues must be addressed: what automation scheme is required? How are communications implemented? This article addresses these issues with example solutions for overhead feeder automation.","PeriodicalId":435675,"journal":{"name":"IEEE Computer Applications in Power","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121357689","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 good MMI can reduce the chance of making trivial errors that could be detected only very late during the simulation process, resulting in a great deal of wasted time. Nevertheless, in the electrical engineering community, programs that are not optimal on the MMI side are still in use. This article focuses on a study of the MMI main issues for a plotting program to visualize simulation and measurement data effectively.
