This paper investigates the effect of static var compensators(svc) on the dynamic stability of an alternator connected to a long transmission line. Frequency response methods are used to assess the closed loop system stability and to define the parameters of a control scheme in accordance with which the svc is controlled to improve the dynamic stability performance of the system. The effect of this form of control on all modes of oscillation including the shaft torsional modes is considered. It is shown that if the VAR consumption of the compensator is controlled in accordance with a terminal voltage signal,the torsional modes of oscillation may be aggravated. However, a scheme incorporating an additional current signal will ensure wider dynamic stability limits and at the same time will improve the damping of the torsional modes. The paper investigates also the compatibility of an excitation control scheme, used to achieve the same goal,and the svc control scheme. |
