EP-Based Optimisation for Estimating Synchronising and Damping Torque Coefficients

This paper presents Evolutionary Programming (EP) based optimisation technique for estimating synchronising torque coefficients, Ks and damping torque coefficients, Kd of a synchronous machine. These coefficients are used to identify the angle stability of a system. Initially, a Simulink model was utilised to generate the time domain response of rotor angle under various loading conditions. EP was then implemented to optimise the values of Ks and Kd within the same loading conditions. Result obtained from the experiment are very promising and revealed that it outperformed the Least Square (LS) and Artificial Immune System (AIS) methods during the comparative studies. Validation with respect to eigenvalues determination confirmed that the proposed technique is feasible to solve the angle stability problems.
