Con Edison's distribution systems supply power to more than 3 million customers in New York City and Westchester County. About 85% of the load in the Con Edison service territory is supplied by underground low-voltage network systems. The reliability of underground low-voltage network systems is extremely high and Con Edison uses Network Reliability Index (NRI) programs - the Contingency program and...
This paper presents methods for estimation of the value of the 3-phase bolted short circuit current of induction distributed generators. It justifies new, quick, and fairly simple way for approximation of the value of peak currents during the first several cycles of the fault. During the study, numerical simulations of the fault have been performed and compared to the results from the estimation....
This paper describes the design and implementation of a unit substation demand estimator (USDE). The paper presents various methods for the estimation of missing data measurements in a 4kV distribution network. Each method is tested in detail to validate the accuracy of the estimated data and an estimation process strategy is suggested. By using the successive estimation methods and Microsoft Excel...
