Power plant tripping

Increase Productivity through Harmonic Solution

Increase Productivity

Abstract- Harmonic solution is an engineer's approach to total productive maintenance (TPM) to Increase Productivity. No stoppage. No breakdown. No quality rejection. A 3500 TCD sugar milling unit was operating at 3000 TCD due to frequent drive stalling problem with dc mill motor. To increase productivity and sugar recovery, it installed a 2000A passive tuned harmonic filter in 2010, at a 3MW 415V Turbine Generator (TG).

Mitigate VFD Harmonic

VFD Harmonic

Abstract - VFD Harmonic forced a power plant to shutdown due to power quality failure. Starting with drive tripping it blasted switch gear, bus bar & electrical panel. This IPP with a 25mw, 11kV, 50Hz power plant and 5000TCD sugar milling unit had completed its first anniversary without harmonic problem. But during 2nd year's operation, it started-off with a massive blast of a 6300A Air Circuit Breaker (ACB). It was at the incomer of an electrical panel. The 415V PCC panel was supplying to sugar plant's process load.
