2 Diesel Generator – Working Principle © P2Power Solutions Pvt. Ltd DIESEL ENGINE ALTERNATOR LOAD chemical mechanical electrical

3 Diesel Generator – Fuel Consumption Pattern © P2Power Solutions Pvt. Ltd maximum >70% loading efficiency increases with DG size

4 © P2Power Solutions Pvt. Ltd Ensure steady load conditions Minimize load fluctuations Ensure balanced loading Minimize load harmonic distortions Ensure optimum loading (>70%) Ensure air at generator intake is cold and dust free Ensure fuel oil storage, handling and preparation as per manufacturers' guidelines Calibrate fuel injection pumps frequently Diesel Generator – Operating Guidelines

5 © P2Power Solutions Pvt. Ltd Diesel Generator – Load Characteristics Increased current demand Increased winding losses Underutilization of capacity: increased capital expenditure, lower efficiency. Unbalanced output voltages Heating in alternator windings Underutilization of capacity Overstressing of generators Distorted voltage profile Heating in alternator windings Underutilization of capacity
