Feasibility study of transient stability analysis for operator training simulators

Abstract

The existing operator training simulators (OTSs) simulate the slow dynamics of power systems in real time but this limits the capability of simulating accurate dynamic behaviour after a disturbance. A feasibility study for the modelling of real time transient stability behaviour in the OTS is described. The goal was to analyse not only the CPU timing for the OTS simulation cycle with real time transient stability analysis but to also investigate the resulting improvements in the quality of the OTS. The results confirm that the transient stability can be simulated in real time for systems of realistic size on readily available workstations. More importantly, the results show significant differences in the dynamic behaviour when transient stability is simulated, strongly suggesting that the present OTSs do not provide enough accuracy for training under certain conditions.
