ABSRACT Sliding mode control has received much attention due to its major advantages such as guaranteed stability, robustness against parameter variations, fast dynamic response and simplicity in the implementation and therefore has been widely applied to control nonlinear systems. This paper discus the sliding mode control technic for controlling hydropower system and generalized a model which...

Using hydraulic energy from irrigation flows to become electrical as renewable still needs be conducted. Therefore, this research aims design a pico hydro turbine building powered by water and its tests analyses. The has been simulated with the CFD (Computational Fluid Dynamics). method used in study is solver approach simulation which analyzed flow s imulation applications using kinetic equati...

The paper presents modeling the hydro-turbine governing system with delay in application to turbo-machinery control. originates from wave phenomenon encountered pressure water conduit connected turbine. To facilitate PID control tuning turbine and model is linearized it results linear time referred as neutral system. Particularly, disturbance rejection achieved by response varying power loads. ...

The energy demand in the World is increasing day by day due to rapidly increasing population and advancement in science and technology. But in present era there are too many obstacles which decrease the consumption of electricity for common peoples, high cost of fuel, high demand and low supply of fuel. Fuels like coal, petroleum, CNG, LPG, nuclear energy are depleting day by day and also degra...

Globally faster consumption of hydrocarbon fuel in the transport sector is posing threat to environmental and ecological imbalances and thereby depletion of hydro-carbon fuel is causing another challenge to oil reserves. In view of these issues extensive researches are being carried out to explore the alternative energy source and or to find out appropriate energy conversion system. The atmosph...

The feasibility and sustainable operation of tidal lagoons and barrages has been under scrutiny over uncertainties with regards to their environmental impacts, potential interactions and energy output. A numerical modelling methodology that evaluates their effects on the hydro-environment has been refined to consider technical constraints and specifications associated with variable turbine desi...

The objective of this paper is to investigate the cause of several unexpected high amplitude oscillations that occurred in the surge tank water level of a real hydropower plant during secondary load-frequency control (LFC) maneuvers, after the replacement of the turbine runner, and to propose solutions that allow the power plant to continue providing secondary LFC in a safe and reliable manner....

The availability of non-renewable energy has recently been running low and so impacts electrical energy. Renewable is converted from natural sources to kinetic Double Propeller Water Turbine a water turbine that suitable be applied using small flow head. This research development previous by changing the degree inclination blade angle on turbine, which used determine changes in power efficiency...

This chapter proposes a solution for the control of micro hydro power stations for island operation based on the characteristics of hydraulic turbine nonlinear model with the use of a self-excited induction generator. To control the frequency of the turbine it was considered the non-linear model applied to this type of turbine and the use of a frequency regulator, with characteristics of a prop...

This work analyses the configuration and operation principles of hybrid wind-hydro power plants with pumped storage integrated into autonomous electric grid systems, in order to support high wind energy penetration. The plant consists of wind generation units, combined with a pumped-hydro storage system. It operates on a daily basis, storing the surplus wind production by pumping water in an el...
