The article focuses on the issues of Load Frequency Control (LFC) under non-linear strategies in multi source multi area hydro thermal system. On practical perspective dead band, boiler dynamics, reheat steam turbine along with hydro turbine operating under two different area capacities are considered in the system. When subjected to random load variations in both the areas, the system exhibits...

This paper presents a new approach to Load Frequency Control (LFC) for a hydro-power plant. The control algorithm combines sliding mode control with H∞ technique. The dynamic model of an entire hydro-power plant has been developed. The sliding hyperplane is constructed by H∞ full state feedback control method. The ideal lossless turbine-penstock model is used in this paper to conduct the simula...

The recent increased number of black outs in the power system has been largely due to growing competition and deregulation among the power industry. Power systems are complex nonlinear systems and often exhibit low frequency electro-mechanical oscillations due to insufficient damping caused by severe operating conditions. This needs an advanced modeling and control techniques for effective cont...

Hydroelectric power plants are known for their ability to cover variations of the consumption in electrical power networks. In order to follow this changing demand, hydraulic machines are subject to off-design operation. In that case, the swirling flow leaving the runner of a Francis turbine may act under given conditions as an excitation source for the whole hydraulic system. In high load oper...

Unlike conventional hydro and tidal barrage installations, water current turbines in open flow can generate power from flowing water with almost zero environmental impact, over a much wider range of sites than those available for conventional tidal power generation. Recent developments in current turbine design are reviewed and some potential advantages of ducted or “diffuser-augmented” current...

Nearly two billion people worldwide have no reliable access to electricity, a vital part of the path to development. Micro wind power is one promising solution. Micro wind installations offer environmental sustainability, low capital costs, and excellent adaptability to diverse environmental and cultural situations. Yet, electrification projects in the developing world, including small-scale wi...

In this work a response surface approach was used for predicting the hill chart of a small horizontal shaft Kaplan turbine. To this aim, artificial neural networks (ANN) were chosen as a fast, reliable, and computationally inexpensive tool. The training of the ANN was based on computational fluid dynamics (CFD). The optimization of the runner-guide vane stagger correlation is a time consuming a...

Micro-hydro Power Plant (MHPP) is a small-scale power plant that uses hydroelectric as its driving force, such irrigation canals, rivers or natural waterfalls using the height of waterfall (head) and amount water discharge. Yeh Dikis River, Banjar Lebah, Tabanan Regency supporting location for construction Micro Hydro which useful in planning tourism development around river. The results measur...

This study aims to develop a simple-practical design procedure determine the appropriate size of turbine's outer radius for any given internal parameters according available flow rate through numerical calculation. The calculation is performed using python programming language by combining existing model Archimedes turbine, including power model, turbine capacity, and losses modeling, into proc...
