Computerized procedure for short range planning of a designated distribution area

Presents a computerized procedure for the assessment of distribution system planning. The proposed procedure was developed on a personal computer and is good for a designated area where multiple existing substations and multiple potential sites are considered. This procedure employs load flow analysis and considers the constraints of voltage drops and line flows. Various options are provided to satisfy the load. Losses and costs are evaluated for each case. An example is shown for a designated area and a target year, where the number of new feeders, transformers, substations and associated costs and losses were found for each option. The presented procedure could be deemed as a short-range planning method.<<ETX>>
