A real-time simulator is required for analyzing the effect of the addition of new devices to a large power system before final installation is performed. More realistic results are obtained when the actual pieces of equipment are used in the simulations. This requires the real-time simulation of the power system to which the new equipment will be added. In order to achieve this objective, a new digital simulator based on a hypercube type massively parallel computer, the NCube2, has been developed. The new simulator features: Real-time simulation of a large power system which covers transient stability through long term behavior with constant accuracy level in root mean square values. User friendly man-machine interfaces which mimics the actual operating environment including interactive setting of several system parameters and real-time data presentation on a CRT. High speed A/D (Analog to Digital Converter), D/A (Digital to Analog Converter). D/IO (Digital Input and Digital Output) interfaces are used to connect the digital simulator (power system dynamic model) to actual equipment. This paper describes the basic characteristics of the new digital simulator and presents results obtained in real-time simulations.
