Consider you have to set a power plant for powering up the up hilled areas of Nathia-Galli Abbottabad by harvesting the hydro-energy from Nathiya-Galli Water-fall. As a major gas pipeline of SNGPL has already been laid near the water-fall, therefore, to low capacity of hydro-energy, we can also set a Gas turbine based Generating units as standby / peak load plant in combination with hydro-turbine plants.

(1) You have the availability of both types of Gas Turbines i.e Open Cycle & Closed Cycle. Investigate the feasibility for selection of the type of Gas Turbine Power Plant from above-mentioned types, which will be more suitable under following available conditions / resources:

a. Frequently changing Load conditions / constant load conditions

b. Cheap fuel / costlier fuels to be used

c. Nuclear Reactor based Heat exchangers / Combustion Chamber based Heat Exchangers

Part B:

Consider a Pumped storage micro-hydel plant is to be built as a Peak load-plant on above mentioned Nathiya-Galli Water Fall with available head of 39 m and average discharge of 5640 m/hour from the upper pound. The hydraulic efficiency and electrical efficiency of the plant to be 0.86 & 0.92 respectively.

Analyze the following output from the above Pumped Storage Plant:

a. Hydro-Power and Annual Hydro-energy available b. Electrical Power and annual electrical energy units that can be generated from the plant.
