Managing the widely distributed wood pole assets owned by typical electric power utilities in the USA is challenging in the absence of appropriate analytical tools. The traditional method of inspecting poles by headquarters or strictly age is insufficient for effective management since natural hazards cause the largest instantaneous pole replacements. A probabilistic framework is developed and presented...
In this paper a methodology for calculation of the optimum size of a stand-alone hybrid wind/photovoltaic (wind/PV) system is developed. The collection of six months of data of wind speed and ambient temperature recorded for every hour of the day and an estimate of solar irradiance were used. These data and manufacturer's specifications on a wind turbine and a PV module were used to calculate the...
This paper presents a new methodology of sizing optimization of a stand-alone hybrid renewable energy system. The developed approach makes use of a deterministic algorithm to minimize the life cycle cost of the system while guaranteeing the availability of the energy. Firstly, the mathematical modeling of the principal elements of the hybrid wind/PV system is exposed showing the main sizing variables...
This paper discusses in detail the design, installation and operation of an independent power system for a UHF repeater operated by the Canadian Broadcast Corporation. This remote, helicopter-access-only, site is located on Pigeon Mountain in Exshaw, Alberta, above the Trans-Canada Highway. At 9000 feet elevation with a 2000 foot cliff surrounding three sides this site experiences very high winids...
