Principle & operation of generator :-
• A generator is a machine by which mechanical energy is transformed into electrical energy.
• Generators can be sub-divided into two major categories depending on the electric current produced is alternating current (AC) or direct current (DC)
• The basic principle on which both types of generator works is the same

• The Generator Works upon the Principle of Faraday's law of electromagnetic induction.
• 'when a conductor moves in a magnetic field (cutting the magnetic flux lines), an emf gets induced in the conductor'.
• The direction of induced emf can be determined with help of Fleming's right hand rule

Short Comings of Existing DG SET
• Capacity of installed DG SET is not as per actual load it fulfil the utility requirements of KDM complex.
• Generator is not suitable for environment.• Existing DG SET is not energy efficient.• Fuel consumption is high. • High maintenance required.• Generates high noise (65-75db).

CALCULATION FOR PROPOSED DG SET
• TOTAL EXISTING LOAD: 311 KW
• CONSIDERING POWER FACTOR =0.8 311/0.8 – 388.75 KVA
• THEN EXISTING LOAD IN KVA=388.75
• SAY TOTAL =400 KVA
