Load Commutated Inverter Modeling: Impacts and Solutions for an Isolated Power System

This paper explores the impact of several medium-voltage load commutated inverter motor drives on an industrial power system. The impacts of load commutated inverter transients on the facility’s power system, the external utility grid, and its remedial protection and control systems are explored through modeling the load commutated drive system, protection devices, and the control system with a real-time control hardware-in-the-loop simulation.
