Voltage Stability Study on Radial Distribution System Incorporating Induction Motor Loads

This paper presents a computationally efficient approach to perform load flow analysis on radial distribution systems. Further, a study has been conducted on the mercurial voltage profile of a distribution system when an Induction Motor with varying load is incorporated into the distribution system. The impact on the voltage profile of the system has been assessed when the induction motor uses star and delta configured stator connections. The voltage profile study is being extended for improvement with the employment of permanently connected capacitors across stator windings. Modeled objects were implemented in MATLAB programming, a high-performance language for technical computing, and tested with 33-bus radial distribution network.
