Abstract

In the last chapter, the method of the nonlinear excitation control (NEC) design and its effects have been presented. It has been manifested that adopting the NEC scheme brings higher-level stability and better dynamic performance of power systems. However, the improvement of transient stability is limited due to the ceiling excitation voltages and the voltage response time limit. In order to make further improvement on the transient stability, the nonlinear control theory should be applied to the control on valve opening of steam turbines or hydroturbines [1–8]. Because of the water hammer effect, using the water gate opening control to improve the transient stability is not so effective. In this chapter, the nonlinear steam valving control will be studied.
