A power station has to supply load as follows:   Draw the load curve Draw the load-duration curve Give a scheme of suitable generating units to supply the level Calculate load factor, capacity of the plant and plant capacity factor.

Need ASAP thank you

A geothermal resource/aquifer has been tested and confirmed to continuously produce saturated liquid water at 230°C. It is desired to construct a 60 MW geothermal power plant, which will utilize this resource. Two designs are proposed: a) a single flash unit and b) a dual-flash unit. A nearby cooling pond may supply sufficient cooling water to keep the condenser of the plant at 40°C. For the two types of units under consideration calculate: a) The total amount of steam that needs to be produced. b) The total amount of water the wells must provide. c) If each well produces 60 kg/s of water, what is the number of wells that must be drilled?

Power generation using steam is one of the most common method which can be found around the world. In these type of power plants, steam goes through a basic thermodynamic cycle called Rankine cycle which is shown in the following figure. Steam flow Boiler Qin Pump Wout Win Condenser •Qout For the proper operation of the cycle, water should be pumped to the boiler using pump which required work input (Wm) generate steam and then high pressure steam is fed to the turbine. By extracting the energy from high pressure steam, turbine is producing work output (Wout). Because of this, the steam pressure is reduced and low pressure steam is flowing into the condenser. Condenser removes heat energy from steam further (Qout) and steam is converted into liquid water. The liquid water can be pumped into the boiler again and the cycle continues. Performance of a Ranking cycle can be evaluated by using thermal efficiency (nth)which is determined from; the cycle. Heat energy should be supplied to the…
