Real-Time Simulation of Electrical Distribution Systems

Abstract

The scope of simulation of electrical systems for nuclear power station training simulators has broadened to keep pace with the demand for larger scope and higher fidelity balance of plant models. This increase in scope has created a need for electrical distribution and grid models that are capable of simulating complex distribution network configurations with many different types of loads and parallel sources. Along with the requirement for increased model scope and fidelity is the desirability of the model to be applicable to various different plant distribution systems, irrespective of voltage level and system topology. Further, the model must be capable of exhibiting symmetrical fault behaviour allowing for the propagation of fault currents throughout the system in the event of fault isolation failures. Presented is a discussion of the techniques employed in the development of such a model suitable for use within a real time training simulator environment.
