Novel Stand-Alone Small Hydro Renewable Energy System;Outline;The Hydro Power Advantage;Canada’s Role as a Hydro – Power Producer;The Classification of the Hydro-Electric Systems;The Capacity-wise Categorization;By Types of Installation;Type of Turbines ;Reaction Type Turbines;Kaplan Turbines;Impulse Type Turbines;Turbines can be split into four main groupings (although they do of course overlap and one may disagree on where one group starts and ends).;The Nominal Power Capacity of a Small Hydro Power System;Starting the Simple Power Calculations;AN EXAMPLE OF A TYPICAL CALCULATION [Lower Kotmale Project, Sri Lanka];Why Hydro – Power is renewable? Hydropower is considered a renewable resource because water, which nature makes available each year through the hydrologic cycle, is used as the energy source to generate power. Rural Electrification Policy ? The important part of Rural Electrification is the mobilization of Renewable Energy (RE) sources, where they are cost-effective, and the promotion of RE technologies ;How to Electrify Rural Areas or Best Sources for a Stand-Alone System ;Again, the Small Stand-Alone Hydro Power Systems can be divided into TWO Main categories :;The Traditional way of achieving (CV – CF) Constant Voltage, Constant Frequency in Stand-alone Asynchronous Generator run Hydro Power System ;The Research Tasks;The Sample VV – VF Stand-Alone Small Hydro System System has Linear, Non Linear and machine Loads How you solve the Reactive Power problem, as you are dealing with an asynchronous generator? Where are those Traditional Dumb Loads? Why Matlab / Simulink? But, not Matlab, C or Fortran programming?;Sample Study Stand–Alone Small Hydro Power System;The Hybrid Load Centre;The Modulated Power Filter and Capacitor Compensator [MPF / CC] How you select R? The Carrier Frequency? Why IGBTs/Mosfets? Can’t I go for GTOs or Thyristors or IGBTs?;The New Proposed Way : Novel Modulated / Switched Power Filter and Compensator Capacitor ;;The Pow
