Small hydro schemes
POWER ENGINEERING JOURNAL APRIL 2002 61 I nduction generators are commonly used for small hydro schemes due to advantages such as availability, low cost and robustness. The cost per kW of a single-phase generator is generally higher than a threephase generator. Hence a three-phase generator, which produces a single-phase output, is normally used. In order to minimise further the capital cost, c...
متن کاملSome New Developments in Small Area Estimation
Small area estimation has received a lot of attention in recent years due to growing demand for reliable small area statistics. Traditional area-specific estimators may not provide adequate precision because sample sizes in small areas are seldom large enough. This makes it necessary to employ indirect estimators based on linking models. Basic area level and unit level models have been extensiv...
متن کاملMaximum Efficiency Point Tracking for Adjustable - Speed Small Hydro Power Plant
The paper presents the general scheme and the relevant implementation of a Maximum Efficiency Point Tracking (MEPT) system for a Small Hydro Power (SHP) plant equipped with a variable-speed generator. This last consists of a Doubly Fed Induction Generator (DFIG) and a power electronic converter that independently controls both the rotor speed and the generator power factor. The MEPT is designed...
متن کاملConservation and sustainable exploitation of plant genetic rsources: International developments
Plant Genetic Resources (PGRs) are one of the most valuable natural resources of anycountry. Biotechnology through genetic engineering of plants and the creation of new plantvarieties can increase the value of these resources. Different technical and legalmechanisms such as ex situ/in situ collection of PGRs, and Intellectual Property Rights(IPRs...
متن کاملSimulation Model of Hydro Power Plant Using Matlab/Simulink
Hydropower has now become the best source of electricity on earth. It is produced due to the energy provided by moving or falling water. History proves that the cost of this electricity remains constant over the year. Because of the many advantages, most of the countries now have hydropower as the source of major electricity producer. The most important advantage of hydropower is that t is gree...
