An expert system prototype was developed for assisting distribution system dispatchers in their responsibility of restoring electric service to affected customers, whenever an outage occurs. It is intended to monitor the system and advise the operator of the location of the protective device most likely to be out of service. The benefits of using a system like this will be improved dispatching of repair crews and potential improved economics for the electric utilities. After intensive validation and testing of the prototype using actual feeder files, results were consistent, and within acceptable computational time.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.

The updated voltage and current vectors are the estimates of the 60 Hz phasor quantities obtained using a recursive optimal estimation algorithm. The distance to the fault is then estimated using a method based on the apparent impedance approach and the updated voltage and current vectors. Another consideration is the ability to determine the fault location on a lateral. A simulation of an actual rural distribution feeder using the electromagnetic transients program (EMTP) is used to illustrate the concepts of the approach and to show the accuracy and speed of this fault location technique, even on a temporary fault that lasts only for a few cycles.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.

The survey revealed a considerable interest by the cooperative segment of the US power industry in distribution automation. Cost, however, is the key factor that will determine whether this interest will turn into implementation. The survey also revealed that a moderate number of cooperatives now have distribution SCADA (supervisory control and data acquisition). It also uncovered some clear patterns among cooperatives in the perceived performance of, and preference for, communication systems for distribution SCADA and distribution automation.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.

It also provides intangible benefits such as improved public image and market advantages. A utility should evaluate the benefits and costs of such a system before committing funds. The expenditure for distribution automation is economical when justified by the deferral of a capacity increase, a decrease in peak power demand, or a reduction in O&M requirements. The three modules of a distribution automation system are examined along with the costs of distribution automation.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.

The survey form was similar to one used by Cornhusker Public District in 1985. The format permitted entry of the data into a Lotus 123 spreadsheet for summary and analyses. Questions were included to identify general characteristics of the customer's needs or concerns. The customers also rated the quality of service of their public power district. Future agricultural developments were identified. The surveys were sent out in the January-April period of 1989 as selected by each power district. There were 3822 surveys returned of the 7020 sent out. In the 1985 survey of Cornhusker 2940 responses were received. The combination of the two surveys represents 6762 rural households. The graphical results of the survey which are presented are the combined results for the four public power districts, Butler, Polk, Seward and York.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.

The authors summarize the major power quality problems experienced at the various industrial sites and present some of the significant results of an across Canada questionnaire survey on 'On-farm Electrical Power Disturbances.' The results of these surveys will provide a basis for mitigating actions by the utilities and their rural industrial customers by enhancing their ability to identify possible origins of power supply disturbances affecting the performance of electronic and electrical equipment at the various farm industrial sites.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.
