A site with an average wind velocity of 9 m/s is to be designed using wind turbine as energy source. What is the potential power available in the wind if a 2 meter wind turbine will be installed

5-25 Electric power is to be generated by installing a hydraulic turbine-generator at a site 110 m below the free sur- face of a large water reservoir that can supply water steadily at a rate of 900 kg/s. If the mechanical power output of the turbine is 800 kW and the electric power generation is 750 kW, determine the turbine efficiency and the combined turbine- generator efficiency of this plant. Neglect losses in the pipes.

Using PV Curve explain the effects of more real power, increasing excitation and how this helps maintain frequency. Describe the interlink between load angle and power.

How do the capacitor and inductor support the circuit in power factor improvement?
