Title: Oscilation Properties of the Mathematical Model of Hydro Turbine with a long Penstock - Part 1
Keywords: Water turbine, speed control, long penstock modeling, Pade approximation, water column compensation

Abstract: In this paper a detailed model of the system hydro-turbine generating unit with a long penstock is described. Different model approximations are investigated. They are based on the Pade approximation of the time delay and on the approximation of the hyperbolic function in the model description. A speed and power control system using LQR technique is designed. The controller structure incorporates a conventional PID control and a water column compensation. Different water column compensations based on the approximation of the hyperbolic function are investigated. An exact water column compensation is proposed. It is shown that a water column compensation improves the stability margins and dynamic performance.
