1. Wind Power Integration in Power Systems with Transmission Bottlenecks
Abstract : During the last two decades, the increase in electricity demand and environmental concern resulted in fast growth of power production from renewable sources. Wind power is one of the most efficient alternatives. READ MORE

2. CFD of Air Flow in Hydro Power Generators
Abstract : The air flow through a generator has been numerically investigated with different rotor and stator designs to give a better understanding of the flow for cooling purposes. A simple rotor design has been chosen to start with, and modified through a set of changes, where stepwisemodifications have been imposed to the design of the rotor and the stator. READ MORE

3. Power System Damping - Structural Aspects of Controlling Active Power
Abstract : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. READ MORE

4. Ventilation of a Model Hydro-Generator, An Experimental and Numerical Study
Abstract : Generators are sophisticated machines used to convert the mechanical energy of a prime mover into electrical energy. Electromagnetic and mechanical losses accompany this energy conversion process. Cooling systems remove the heat, generated by losses, from these machines. READ MORE

5. Ventilation Flow Field Characteristics of a Hydro-Generator Model- An experimental and Numerical Study
Abstract : Hydro-generators are complex machines used to convert the mechanical energy of the water turbine into electrical energy. Electromagnetic and mechanical losses accompany this energy conversion process which will cause heat generation and temperature increase. Cooling systems are needed to remove this excess heat from hydro-generators. READ MORE
