Abstract

Auto-parametric resonance has not been detected nor observed in a real power system, probably because the problem-oriented instrumentation network is not available today. It has been confirmed by our research group from the viewpoint of theory, digital simulations, and artificial transmission system with rotating machines that the auto-parametric resonance may come out in a power system where certain types of resonance conditions are satisfied as when the initial transient impact such as line opening, generator tripping, and a line-to-ground fault has been applied.<br>The objective of this paper is to confirm the auto-parametric resonance phenomena on a large-scale advanced-type power system simulator (APSA) which features various functions which are very close to those of a real power system, and to promote the instrumentation techniques needed to record and analyze such infrequent phenomena.
