Abstract
A kind of nonlinear optimal governor additional control was put forward in the paper by using feedback of power angle and rotator speed. Because the design of governor in real system is complex, it is useful to consider the affection of the original feedback of rotator speed. It will be easy and feasible to adopt the additional control method for improving generator stability in real system. The dynamic simulating test of restraining low frequency oscillation and three phases short circuit in one-machine infinite-bus power system have been done by adopting NOGAC. The results of the test show that it is able to improve the static stability and transient stability of turbine generator, it can be used to restore synchronous operation of generator, the output of NOGAC is continuous, and the character of NOGAC is better than that of fast-valving.关键词
