Recent Developments in Digital Real Time Simulation for Power Systems

摘要

This paper introduces important new developments in digital real time simulation of electrical power systems and their complex components. Particular emphasis is placed on two recent developments, the voltage source converter (VSC) model and the phase domain frequency dependent transmission line model. Various issues such as background, algorithms, implementations, applications and validation have been described and included in the paper.The paper also provides insight into the specific challenges faced when real time digital simulation is considered. Approaches commonly used in non real time simulation programs are not always possible when real time operation is required. For this reason accurate and efficient alternative methods must often be developed, implemented and validated.
