چکیده
This paper presents part of the work carried out within the framework of a research project entitled Application of variable speed and intelligent control technologies to hydropower generation. Specifically, it is focused on the activities performed in order to achieve one of the main objectives of the project: the design of a water level control system for a low-head run-of-river variable speed small hydropower plant. A speed-based water level control system has been implemented in a laboratory plant and manages successfully to control the water level in the head pond. In addition, a model of the control system has been developed using Matlab-Simulink®, the validity of which has been verified by comparing experimental measurements with simulations results.

Stability Analysis of a Run-of-River Diversion Hydropower Plant with Surge Tank and Spillway in the Head Pond
Run-of-river hydropower plants usually lack significant storage capacity; therefore, the more adequate control strategy would consist of keeping a constant water level at the intake pond in order to harness the maximum amount of energy from the river flow or to reduce the surface flooded in the head pond. In this paper, a standard PI control system of a run-of-river diversion hydropower plant w...
متن کاملGovernor design for hydropower plants by intelligent sliding mode variable structure control
This work proposes a neural-fuzzy sliding mode control scheme for a hydro-turbine speed governor system. Considering the assumption of elastic water hammer, a nonlinear mode of the hydro-turbine governor system is established. By linearizing this mode, a sliding mode controller is designed. The linearized mode is subject to uncertainties. The uncertainties are generated in the process of linear...
