| Popis: | This paper presents a hybrid-type stability control method based on fuzzy control to improve power system stability. The proposed method consists of a speed deviation input fuzzy controller (F1), an electrical power deviation input analog-type PSS (ΔP-type PSS), and a fuzzy judgment mechanism (F2). By using the membership function of the magnitude of speed deviation/acceleration of the generator, the following control schemes are considered. If the magnitude is large, then the supplementary stabilizing signal computed by F1 is used to damp oscillations as fast as possible. Otherwise, the output signal of ΔP-type PSS is used to avoid undesirable noise effect due to noisy input signal of the speed deviation of F1. The proposed control method increases the power system stability greatly, and it is simple to implement. The effectiveness of the method is demonstrated by one-machine infinite-bus and multi-machine model systems. |
