Abstract
Based on the investigation on the properties of the water turbine governing system, an adaptive control strategy is proposed. The most important feature of this control strategy is that its control law is adjusted according to the operating modes of the system. A new control algorithm for a water turbine governing system in its unloaded unsynchronized operation is developed. Instead of using identification routine, a practical procedure for determining the controller parameters is established. A new load-change method is presented by combining the feedback and feedforward concept. This can bring some convenience to the operators of the power plant, economic benefit and stabilizing factor to the network. A new robustness stability design algorithm based on pole-shifting technique is developed for the case when the hydro-electric generating unit is operating in the synchronous mode. It can provide stability in the entire operation range. Simulation studies are performed with the proposed control strategy on a water turbine governing system. It is observed that better system response is achieved using the proposed strategy in comparison to the conventional control.
