This paper presents a discussion of the principal control strategies for frequency control in hydro-turbines and their performance under nonlinearities. Practical considerations for the dynamic modeling of the control systems in hydro-turbines are introduced. Actuator dynamics and their importance in the control loop are analyzed. A study is also performed on an exemplifying small hydro system to...
In this paper, actuator fault detection and isolation is designed for two-area Automatic Generation Control (AGC) system. To isolate and estimate the possible actuator faults a bank of Sliding Mode Observer (SMO) is designed. Based on the designed observers, bank of residuals are defined correspondingly. The actuator faults can be isolated if only one residual goes to zero while the others do not...
