Investigation and Mitigation of Various Voltage Issues at a Rural Manufacturing Facility with a Unique Configuration

This paper investigates various voltage issues at a rural manufacturing facility connected to a 115 kV transmission system. Low voltage issues during and following the tripping of an on-site generator and high and low voltages during the switching of a nearby mechanically-switched shunt capacitor bank have caused challenges to the operations of the facility. Through dynamic simulation for scenarios from past events combined with some potential transmission configurations, the voltage issues are presented and a possible solution is proposed to mitigate these issues.
