n some fatal cases like insulation breakdown in VCB insulator posts, short circuit of tripping/closing coils, etc., the rectification usually requires hours or even days depending upon the availability. Power interruption for lengthy periods is not a very desirable situation whatever the condition inside the substation. In such cases, the operators must be intuitive enough to think out of the box to resume power supply via a temporary solution vis Diesel Generator.

2. INTRODUCTION
Diesel engine is the prime mover, which drives an alternator to produce
electrical energy
a) diesel engine and its accessories.
b) The AC Generator.
c) The control systems and switchgear.
d) The foundation and power house civil works.
e) The connected load with its own components

4. Advantages of adopting Diesel Power
■ Low installation cost
■ Short delivery periods and installation period
■ Higher efficiency (as high as 43 – 45 %)
■ More efficient plant performance under part
loads
■ Minimum cooling water requirements,
■ Adopted with air cooled heat exchanger in areas
where water is not available
■ Short start up time

8. Energy Saving Measures for DG Sets
• Ensure steady load conditions on the DG set, and
provide cold, dust free air at intake
• Improve air filtration.
• Consider fuel oil additives in case they benefit fuel oil
properties for DG set usage.
• Calibrate fuel injection pumps frequently.
• Ensure steady load conditions, avoiding fluctuations,
imbalance in phases, harmonic loads.
• Carryout regular field trials to monitor DG set
performance, and maintenance planning as per
requirements.

9. Maintenance Aspects
• Battery Set
• Coolant
• Lubrication
