Construction Industries Solution

Typical Challenges

• Hunting of Diesel Generator even at partial loading condition
• Heating of DG alternator
• Low power factor leading to increased reactive stress

Root Cause Analysis

• Complex load profile of heavy construction machines such as crane and welding demanding high reactive power which DG sets are not designed to supply
• Increased reactive stress on DG due to sudden spikes/jerks in reactive power
• Inflated peak kVA demand due to transitory reactive jerks

Solution

• P2 Power Hybrid Filter at DG incomer (p2p-415-hf3)
• P2 Power Hybrid Filter at DG incomer (p2p-415-hf4) - in case neutral current is high

Benefits

• Reduced reactive stress on generator and therefore reduced peak demand
• Elimination of DG hunting and alternator heating
• Reduced fluctuations in peak power demand on the generator
• Prevention of de-rating of available capacity; generator can be loaded to its maximum capacity
• Lower capacity generators can be used to support entire load thus resulting in significant savings in capital expenditure on over sized DG sets
• Reduced current harmonic distortion
• Same active/hybrid filter installation can be used to improve power factor on grid supply as well
