'PREMIUM OPERATING DISTRICTS' PROVIDE SUPERIOR RELIABILITY FOR INDUSTRIAL CUSTOMERS USING THE DV2010 PRIMARY VOLTAGE NETWORK

摘要

Customers equate "reliability" to electric service availability. Radial feeder electric distribution systems deliver levels of perceived reliability that are typically in the range of 99.98% available service, i.e., approximately 100 minutes of annual outage time as indicated by SAIDI. The radial distribution system can be enhanced with automation to increase reliability, but even these options result in short duration power outages. New technology in commercial and industrial processes have created an environment were some customers have a zero tolerance of any type of power interruption, where a one second outage may just as well be a one hour outage because their critical processes have tripped offline and product is lost at a significant cost. Networked power distribution systems provide an answer to the high reliability requirements of these sensitive processes. The primary distribution network that is created from traditional radial distribution feeders, uses new advancements in hardware and software technology, and high-speed communication implemented to establish a multi-source distribution network to provide superior service and reliability to the Premium Operating District, "POD". This paper will discuss the equipment, philosophy and system design that is being deployed at We-Energies using the primary distribution voltage network technology that has been developed as a cooperative R&D effort when 6 utilities across the country joined together to form the Distribution Vision 2010, LLC. We Energies is using the DV2010 design to develop a pilot project in 2004 and create a Premium Power Park within the largest existing industrial park in the state of Wisconsin. The design is being implemented over the existing distribution feeder infrastructure and promises to deliver less than one minute of qualified outages to the customers, or 99.9998% available service.
