Research on power system real-time simulation

Real-time simulation has proved to be an effective tool for research,test,plan,operation and security situation assess of power systems.Real-time simulation of power systems technology development experienced physical simulation,digital physical mixed simulation and digital simulation throughout the three stages.This paper introduces the general definition, development and present situation of power system real-time simulation and highlightens the real-time characteristics of this technology.Meanwhile,it illustrates the theory basis,the algorithms involved and implement methods of real-time simulation technology,compares and summaries three simulation technologies to the power system real-time simulation.Because they have their own advantages and disadvantages,they need to be employed selectively in practical application.Digital physical mixed simulation technology in the simulation applications has more advantages and is emphasized.Finally,the scheme of solving the problem of power system real-time simulation technology is put forward.
