Rs. Kuruneru et A. Bose, FEASIBILITY STUDY OF TRANSIENT STABILITY ANALYSIS FOR OPERATOR TRAINING SIMULATORS, IEE proceedings. Generation, transmission and distribution, 144(5), 1997, pp. 510-514
The existing operator training simulators (OTSs) simulate the slow dyn
amics of power systems in real time but this limits the capability of
simulating accurate dynamic behaviour after a disturbance. A feasibili
ty study for the modelling of real time transient stability behaviour
in the OTS is described. The goal was to analyse not only the CPU timi
ng for the OTS simulation cycle with real time transient stability ana
lysis but to also investigate the resulting improvements in the qualit
y of the OTS. The results confirm that the transient stability can be
simulated in real time for systems of realistic size on readily availa
ble workstations. More importantly, the results show significant diffe
rences in the dynamic behaviour when transient stability is simulated,
strongly suggesting that the present OTSs do not provide enough accur
acy for training under certain conditions.
