These \"tailored\" APPs leveraged shared and utilityspecific content to meet the specific needs of each utility, while remaining affordable to small providers. The documents offered guidance on avian management and mitigation to improve avian safety and system reliability, and made use of the best mapping and data collection tools of the day. In 2014, the Utah Associated Municipal Power Systems (UAMPS) contracted EDM International, Inc (EDM) to develop tailored APPs on behalf of 19 member utilities. The UAMPS project used CartoPac Mobile software for field data collection. CartoPac incorporated EDM's project-specific user interface to calculate relative pole hazard in real time, based on key input variables described in the peerreviewed literature, CartoPac also captured pole locations and recorded structure-specific retrofit recommendations. The project achieved significant cost savings by sharing relevant document content, streamlining project management, field work efficiencies, and using the CartoPac platform for mobile data collection. The savings made the benefits of a comprehensive and innovative APP accessible even to small utilities, and provided utility-specific guidance for each operator. These 19 tailored APPs should improve system reliability and reduce violations of federal avian protections laws. The tailored APP approach, with mobile field data collection for the ARA, is a potential template for statewide or regional groups of rural electric cooperatives or other small electricity providers.","PeriodicalId":431136,"journal":{"name":"2016 IEEE Rural Electric Power Conference (REPC)","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127569595","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}

Through the data provided by SCADA systems, investor-owned utilities have been able to improve grid reliability, proactively detect and resolve problems, meet power quality requirements, and support strategic decisions. However, SCADA systems no longer need to be relegated to control room settings that support large systems with dedicated staff. The basic technology that supports SCADA can now be cost-effectively scaled to smaller systems with as few as just one substation. This paper will highlight how smaller utilities may benefit from SCADA functionality, perceived barriers to implementation, typical requirements, technical considerations, and best practices for engaging engineering and construction partners from recent projects.","PeriodicalId":431136,"journal":{"name":"2016 IEEE Rural Electric Power Conference (REPC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115331513","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}

{"title":"Affordable Cable System Reliability and Life Extension Strategy","authors":"B. Lanz, D. Byrne, M. Spalding","doi":"10.1109/REPC.2016.16","DOIUrl":"https://doi.org/10.1109/REPC.2016.16","url":null,"abstract":"Today, there is increased pressure for electric distribution cooperatives to maintain system reliability without increasing membership costs. This challenge is further compounded by the need to maximize existing legacy infrastructure. While membership reliability is a key consideration, a static economy, a commitment to a lower carbon footprint and the need for rate stability are also key factors that translate into increased operating costs. Many consider age to be the silent killer of America's critical infrastructure. The large fleets of equipment deployed by electric utilities and limited real-time monitoring makes it nearly impossible to know the duty each specific piece of equipment has experienced, thus age alone is used as the main determinant of remaining life. The economic and staffing requirements to replace these aged fleets based solely on in-service life is untenable. The need to find a lean approach to better address this challenge has lead to new technologies that provide detailed information about the equipment's true health or condition to allow the right measure of asset rehabilitation, replacement or extended deployment using actual condition assessment. There are millions of miles underground power distribution systems in service today that are operating beyond the original accounting defined depreciation life and failing at an ever increasing rate. Until recently, management of these underground assets was particularly challenging because once put into service, their concealment prevents visible inspection. A new cable life extension process is revolutionizing the industry by providing a means to field assess, rehabilitate and then certify cable systems to like new status. The proven assessment technology has certified more than 90,000 underground cable systems around the world and has shown that over 75% of aged assets still perform as well or better today as they did when they were first installed, decades ago. The Federal Energy Regulatory Commission's (\"FERC\") decision to allow capitalization of this new cable life extension technology is prompting many utilities and electric cooperatives coast to coast to reduce cable replacement budgets and make a positive impact on membership costs. These forward looking utilities have experienced extended capital reach, lowered operating and maintenance (O&M) expenditures, efficient resource utilization, minimal property intrusion and a dramatic real-time improvement in cable system reliability.","PeriodicalId":431136,"journal":{"name":"2016 IEEE Rural Electric Power Conference (REPC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133436946","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 paper considers a synchrophasor system implemented on a distribution feeder that uses two different wireless communications technologies to transmit synchrophasor measurement data simultaneously. This system was implemented to demonstrate advanced distributed generation control and its impacts in terms of grid support on the broader electrical feeder. A wireless serial communications solution and a 3G cellular solution were implemented, allowing a comparison of the performance of these different technologies. Because phasor measurement unit data are continuously streamed at up to 60 messages per second, these data provide a means to continuously evaluate the communications systems. Performance data were measured and archived over a one-week period, providing detailed information to compare the wireless communications technologies implemented. Using this information, recommendations are made in this paper about which wireless technology may be better suited for a variety of utility applications.","PeriodicalId":431136,"journal":{"name":"2016 IEEE Rural Electric Power Conference (REPC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115313362","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}

{"title":"Describing Arc Flash Incident Energy Per Feeder Length in the Presence of Distributed Resources","authors":"Tom Chambers","doi":"10.1109/REPC.2016.17","DOIUrl":"https://doi.org/10.1109/REPC.2016.17","url":null,"abstract":"An approach for arc flash hazard analysis in the presence of distributed resources based on the use of TCC curve equations is proposed in this paper. Determining the available arc flash incident energy and appropriate protective clothing to wear while working on an energized distribution feeder can be a time consuming task. Utilities typically refer to a single, worst-case incident energy per feeder over its entire length to simplify clothing requirements, it is therefore necessary to determine the maximum incident energy present on all feeders that may be worked on energized. The interplay between arcing current and over current protection characteristics makes determining the maximum incident energy and the location of its occurrence a lengthy problem to solve. This is further complicated to a significant degree in the presence of distributed resources. This paper introduces a proposed method that removes the need for an iterative approach in calculating incident energy at several locations on a feeder in a systematic attempt to determine the maximum energy, and introduces the concept of plotting incident energy as a function of system impedance (and so feeder length). This is achieved via an interface to the IEEE 1584 Arc Flash Hazard Calculator correlating discreet impedance increments and available fault current to the time component of TCC curve equations, and plotting the associated arc flash incident energy.","PeriodicalId":431136,"journal":{"name":"2016 IEEE Rural Electric Power Conference (REPC)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115750779","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}

Additionally, they require a relatively large and permanent amount of land with a design life of 40 years and are typically only economical when designed for a specific propose for its distribution of power. However, these designs are not conducive to the requirements of the relatively short-term and/or mobile loads associated with industrial oil and gas production. The use of open-air substations with this type of short-term load can leave the utility with a large stranded investment in equipment that cannot be easily relocated when the short-term load is no longer needed.
