Research on Disturbance Test Scheme for Parameters Identification of Synchronous Condenser

Accurate synchronous condenser model and parameters are the basis for analysis, operation and control of AC/DC hybrid power systems, and the appropriate disturbance test scheme is the premise to ensure parameters identification effect of synchronous condenser. Therefore, this paper studies the field test scheme suitable for synchronous condenser, including excitation step disturbance, load rejection disturbance and terminal voltage disturbance caused by switching capacitors. Then, parameters of synchronous condenser are identified using particle swarm optimization algorithm(PSO). The results show that the parameters identification effect is better under the excitation step disturbance with positive pulse and the terminal voltage disturbance. The effect is even better if multiple groups of parameters identification results under three kinds of disturbances are averaged as the final parameters identification result.
