An Efficient Method for Real-Time Simulation of Large Power System Disturbances

The need for real-time simulation stems from the fact that in many practical situations it is desirable to analyze the dynamic behavior of a large power system with advanced equipment that has complex and high-speed performance. Analog simulators are effective, however they impose serious limitations on the size of the system that is being modeled. We have studied and developed a realtime digital simulator using a hypercube computer, and realized a realtime performance available for the analysis of large power systems. Now as the second step of our study, we developed a digital/analog conversion interface for testing actual power instruments. The interface exchanges the variables of fundamental frequency domain in the real-time digital simulator, and the variables of exact time domain in the analog equipments connected to the simulator.In this paper, we describe the detail of our developed digital/analog conversion interface of real-time digital simulator for testing advanced power instruments. Its conversion algorithm, system configuration of the simulator with the interface, experimental results are also presented in it.
