The effect of local motor loads on power system stability. Prior, Bruce George


The effect of local motor loads on power system stability is investigated. The power system consists of a synchronous generator supplying a large system through a long transmission line. The loads studied are an induction motor, a synchronous motor, and the combination of the two, although a general case of any number of local induction and synchronous motor leads can be easily formulated. Stability is determined by observing the response of the generator and the motors of the system with a fault at the transmission line. The response is calculated from the mathematical model and is- also observed from tests on a dynamic power system model in the laboratory. It is found from the studies that all the local motor loads improve the stability of a power system.
