The feeder topology includes two line sections feeding a critical load, which are supplied by the “Thiess” and “Sub #3” substations. A main-tie-main pole top solution, along with line end voltage regulation, was implemented to minimize the potential impact on the load caused by any fault at the substation or on the feeder. The production process at the critical load facilities required the system to perform any source transfer operation within 6–7 cycles. Therefore, in the event of a fault on the line section with the critical load, the protection system was required to immediately isolate the line section to minimize the impact on the entire distribution system. Due to this requirement, the system employed fast acting differential protection instead of conventional time coordinated curves. Further analysis indicated that the transfer event might cause a significant voltage drop at the line end when both line sections are fed from a single source. The solution for this was to adjust the substation voltage regulators based on the line end voltage. This functionality required a real time interaction between the reclosers in the field and voltage regulators in the substation. This was achieved using decentralized logic architecture and IEC61850 peer-to-peer communication protocol with GOOSE messaging between all devices. The paper will discuss the following: ◾ Source transfer sequences; ◾ Fault isolation concept using jDiffTM differential protection; ◾ Voltage regulation logic; ◾ System design testing and commissioning steps; ◾ Communication and SCADA integration; Field test results.","PeriodicalId":6568,"journal":{"name":"2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"49 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84856418","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}

Initially, a method is discussed which utilizes the availability/reliability of power system components for selecting the optimal locations for PMU placement. The PMU placement problem gives multiple solutions with same number of PMUs for complete observability. Against every solution a bus index called reliability index is evaluated for each bus. Next, overall system index (OSI) is obtained by averaging the reliability index for each optimal solution. The optimal solution having maximum OSI has been selected for PMU placement. This index determines the overall insight of observability for wide area monitoring system. Finally, an index called as Reliability Observability Criteria (ROC) is proposed and evaluated for each PMU installed bus using reliability index. ROC shows the contribution of PMU installed bus in enhancing the observability of the network. The proposed technique has been demonstrated on Eastern Region Indian Power Grid (ERIPG 90 bus system).","PeriodicalId":6568,"journal":{"name":"2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"63 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86141603","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}

Ampirical has upgraded the transmittal of this design data to a more accurate and more efficient interface which utilizes currently available technologies. All design location information can be visualized in a geographical computer software platform such as Google Earth. The most up to date construction statuses are represented with icons and colors.

As more switching devices are deployed on distribution systems, traditional protection schemes are giving way to more advanced, and sometimes centrally coordinated, protection schemes that rely on communications infrastructure. With these communications-dependent systems, the behaviors of the protection with and without the communications infrastructure must be examined. This work has evaluated the impacts of loss of communication in centrally coordinated protection schemes. Two test cases were examined: a sequence of similar faults on a feeder before and after a topology reconfiguration, and a feeder with a photovoltaic (PV) fault current contribution. Both simulations are run in the GridLAB-D™ simulation environment. A simple connectivity model is used to represent communication status. The results reveal that a failure of the communication system can cause significantly different protection behavior. This analysis can be used as a basis for utility engineers to make an informed decision on the impacts of communication losses on their system, as well as evaluating ways to mitigate its impact on the resiliency of the system.","PeriodicalId":6568,"journal":{"name":"2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"74 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90928240","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}

Historically, the use of esters was primarily driven by the need for improved fire safety, with the added benefit of lower environmental impact if spills or leaks occurred. The use of a liquid with a high fire point also allowed more compact, lighter designs which can provide higher power output for a given weight. This principle has been used for many years in applications such as rolling stock and wind turbines, where synthetic esters now dominate. At higher voltages, above 100kV, the use of ester-based insulating liquids has increased substantially in the last 20 years. It is now the case that large power transformers used for transmission and generation projects at 400kV plus can be successfully designed, built and filled with esters. This opens the door to innovation in mobile transformers at ever higher voltage levels, where the ability to gain greater power from a smaller footprint is vital. Coupled with high temperature solid insulation, ester liquids offer an excellent solution for large transformers which can be built within road haulage weight limits.","PeriodicalId":6568,"journal":{"name":"2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"21 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85009427","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}

DWPT has the potential to increase driving range as well as reduce charging time while managing battery related factors including weight, form factor and prohibitive costs. A novel integrated DWPT model for EV charging in Matlab/Simulink was developed to investigate three inductive power transfer (IPT) charging coil configurations: long loop, sectional loop and spaced loop at low, medium and high EV densities (number of EVs per km) in the Caribbean twin island Republic of Trinidad and Tobago. The Highway Fuel Economy Test (HWFET) driving cycle was applied. Simulations of regenerative braking and DWPT using three charging configurations at three levels of EV densities without regenerative braking were compared. The results revealed that the sectional loop and long loop charging configurations offered the greatest benefits; the sectional loop allowed for a 280.1% and 13.1% increase in driving range and a 68.75% and 9.5% reduction in battery capacity for the low and medium EV density cases respectively while the long loop configuration allowed for a 43.2% increase in driving range and 27.5% reduction in battery capacity for the high EV density case.","PeriodicalId":6568,"journal":{"name":"2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"935 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85546898","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}
