The Problem(s) We live in a country where energy shortage is huge problemWith every increasing day the demand of electricity is increasing and Unfortunately the generation is at a standstill As a result the shortfall for power is increasing every day
Energy crisis in Pakistan worsens day by day. Supply and Demand of Electricity in Pakistan Supply and Demand Position: 2008-2015 (MW) 2008 2009 2010 2011 2012 2013 2014 2015 Existing 15,903 15,903 15,903 15,903 15,903 15,903 15,903 15,903Generation Expected Available 13,146 16,110 18,503 20,814 21,167 23,368 23,538 24,408Generation Demand(Summer 16,484 17,868 19,352 20,874 22,460 24,126 25,919 28,029 Peak) Surplus/ Deficit -3,338 -1,758 -849 -60 -1,293 -758 -2,381 -3,621Generation
SecondaryPrimary Problem Problem Overloading Of The Increased bills due to Power Grid electricity wastage.
The Approach to solve the problem There are two ways to solve the problem. • requires large investments Increased and government Generation initiative, which are currently nonexistent. Decreased • limiting the wastage of energy during operation ofconsumption equipment
An analysis of existent reduced consumption schemes.Product based Transient PF Ripple energy Voltage Surge improvement Control:conservation: Suppressor: method: In domestic and commercial loads This is a LOAD Only useful for Expensive as institutions or MANAGEMENT industries markets the surges method. are short lived For such short- Will not benefit if Do not make a lived surges a very installed on Only applicable by sufficient small amount of domestic or loads utility. difference energy is like institutions or conserved offices.
Our Scheme • Overcome the human error in energy wasted during turning loads on and off We • For example in classroomsintend to where there is a set routine to turn the loads on and off • Or offices where there are set times for load usage.
Let us take the example of PNECWe wish to carry out the practical experiment in PNEC• Since PNEC is an institution where loads are scheduled• But it has been seen that electricity is wasted between the periods and in free periods• Hence we plan to record the usage of electric energy for some time.• Then install our system and record the results• We have evaluated the amount of electricity wasted in PNEC in one month• These are only calculations and evaluations the correct view will only come when we implement a recording system
A Rough Analysis Of Wasted Energy.• The total load per class is 40*6 + 60*6 = 600 W or . 6kW• It is observed the energy wasted for 2 hrs. then 2 *.6 = 1.2 kWh• 1.2 kWh * 24 * 5 * 4 = 576 kWh• .6 * 24 * 5 * 4 * 5 = 1440 kWh• total energy 576 + 1440 = 2016• Wasted energy = 576 / 2016 = .28• Which makes 28 % energy conservation.
Hence.• It is our aim to test the project in a section of PNEC at least.• Then display the result of the saved energy• Compare it with proposed saved energy• The result will be used to further enhance the boundaries of our project into a product. Pilot R&D Production Phase
