Outage Management System
An outage management system (OMS) is a computer system used by operators of electric distribution systems to assist in restoration of power. Major functions of an OMS Major functions usually found in an OMS include: * Prediction of location of transformer, fused, recloser or breaker that opened upon failure. * Prioritizing restoration efforts and managing resources based upon criteria such as locations of emergency facilities, size of outages, and duration of outages. * Providing information on extent of outages and number of customers impacted to management, media and regulators. * Calculation of estimation of restoration times. * Management of crews assisting in restoration. * Calculation of crews required for restoration. OMS principles and integration requirements At the core of a modern outage management system is a detailed network model of the distribution system. The utility's geographic information system (GIS) is usually the source of this network model. By combining ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Distribution Systems
Electric power distribution is the final stage in the Power delivery, delivery of electric power; it carries electricity from the Electric power transmission, transmission system to individual consumers. Distribution Electrical substation, substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between and with the use of transformers. ''Primary'' distribution lines carry this medium voltage power to distribution transformers located near the customer's premises. Distribution transformers again lower the voltage to the utilization voltage used by lighting, industrial equipment and household appliances. Often several customers are supplied from one transformer through ''secondary'' distribution lines. Commercial and residential customers are connected to the secondary distribution lines through service drops. Customers demanding a much larger amount of power may be connected directly to the primary distribution level or the subtr ...
