Abstract Renewable Energy Sources (RES) is the spearhead of current global energy and technological market. However, RES has been part our everyday life for many decades. Hydroelectric energy, prime RES’s, had a pioneer presence at non-interconnected island Crete, where Small Power Plant (SHPP) Agia ceased its operation after eighty years service. Subsequently, owner plant decided to grant perm...

The hydro turbine dynamics have a considerable influence on the dynamic stability of power system. In the study of dynamic stability, the system is modeled by the linear differential equations (small  signal analysis). Small signal stability of power systems is needed in all conditions and only is dependent on the conditions of power system performance before commotion occurrence. This paper pr...

Recently, many countries have paid substantial attention to power generation from biomass gasification, particularly through small-scale plants. A number of power plant models have been suggested and analyzed; however, certainly, desirable configurations have not been identified yet. Moreover, their performances are ordinarily difficult to compare, especially owing to the fact that working ...

machine harvesting of legumes in iran is not being done due to unsuitable variety of the plant, lack of farmers' technical knowledge and farms of small scale sizes.currently the plant is harvested by hand and carried to the thresher: yet application of these threshers is not common; they are few in number, and not very suitable for iran. this presentation shows the design and construction ...
