Abstract

As a new type of multiband power system stabilizer, PSS4B has good engineering application prospects due to the huge potential of its inhibition of oscillation in different frequency bands. Aim at the shortcoming of lacking general applicability for PSS4B typical parameters, a hybrid particle swarm optimization algorithm is introduced into the optimization process for PSS4B parameters based on the method of center frequency in this paper, and good phase compensation effect is obtained. By testing the phase frequency characteristic without compensation of self shunt excitation system of Sanjiangkou No.1 generator, PSS4B functional verification test is carried out on the new generation of excitation regulator EXC9200 for the first time. Finally, PSS4B field parameter setting method and the process is summarized, which provides an effective way for PSS4B putting into operation.
