Optimization of MV distribution system designs

Abstract

This paper will present new approach that is advantageous to medium voltage (MV) distribution design configurations for large industrial and power distribution system configurations (specifically Main-Tie-Main) for large industrial and power station installations. Sixty years of traditional low cost design approaches (typical MTM and operated with open tiebreaker) are re-evaluated to demonstrate that traditional low capital cost design may miss improvement opportunities. Those opportunities can be: major capital expenditure (CAPEX) reduction; power quality improvement; MV motor soft starter deletion; improved system stability to name a few. Many designers may not have considered the component interrelationships and/or their tradeoffs when in an integrated system.
