摘要:A new solution to eliminate inter-area low frequency oscillation through accurate control of absolute generator rotor angles is put forward recently. The new solution can achieve no deviating regulation of frequency and absolute rotor angles. As a result, low frequency oscillations can be eliminated. This paper presents the state matrix for a single-machine infinite bus system and a two machine system when the angle controller is applied. Analysis shows that both local and inter area oscillations exist in the two machine system. Increasing the proportional coefficient will decrease the damping ratio for these oscillations, while increasing the differential coefficient will increase the damping ratio. Besides, integration time in the new governor must be big enough, otherwise the system may become unstable. Simulation also shows that, the proportional coefficient should be set to a value as high as possible. This way, angle controller will be more effective, since angle swing caused by disturbance will be restricted to the local area. © 2013 IEEE.
