A Real-Time Line Reclosing Analysis Technique Analysis Using Distribution Factors

This paper describes a recently developed real-time computer program at the control center of the Pennsylvania-New Jersey-Maryland Inter- connection (PJM) designed to determine the impact of returning a transmission facility to service. The method is unique in that it incorporates the use of only megawatt flows and distribution factors. The paper discusses the solution algorithm and the applicability of its use in present and future system monitoring analyses.
