REPLACEMENT OF 380 KVA DG SET INSTALLED AT TECHNICAL AREA DRL, TEZPUR

Technical Specifications – DG Sets (380 KVA) Supply, installation, commissioning & testing of Silent Diesel Generating set, AC, 3 Phase, 50 Hz, capacity 380 KVA/256 KW with CPCB IV+ as per ISO Code 8528-V G3 approved accoustic enclosure, radiator cooled , diesel engine developing 395 BHP at 1500 RPM, complete with standard accessories, coupled to alternator rated at 380 KVA/256 KW, 415 volts, mounted on channel iron base frame, complete with fuel tank of capacity 850 ltrs capacity & DEF tank. AMF Control Panel including 2 Nos 12 Volts rechargeable lead acid battery of suitable AH as directed by Engineer-in-Charge. Disconnecting serviceable LT UG cables from existing LT panel board & old DG Set etc and reconnecting to new DG Set & AMF panel as required and directed at site complete as per directed by Engineer-in-Charge. a) Generator Set Specifications: Prime, Power Rating -380 KVA / 304 KW, 3 phases, Output voltage & frequency (V & Hz) - 415 V, 50 Hz, power factor - 0.8 (Lagging), Current (A) -445 Amps.

b) Alternator Specifications: Alternator suitable for continuous operation generating 380 KVA at 1500 RPM, 415 Volts, 0.8 power factor (lag) suitable for 50 Hz, 3 phase, 4 wire system, confirming to BS 5000 / IS 4722. The alternation is brushless type, screen protected, revolving field, self-excited, self-regulated through an AVR. The alternator has the following features: - - + 1.0% voltage regulation (max.) in static conditions. - IP: 23 protection with insulation class H. - Permissible overload of 10% for one hour in 12 hours of operation. c) Control Panel: - The Control Panel is manufactured with 14/16 gauge CRCA sheet and is powered coated for a weather – proof and long-lasting finish. The Control panel consists of the following parts: - - Controller - Aluminium Bus Bars with suitable capacity with in / outgoing terminals. - indicating Lamps for ‘Load on’ and ‘Set Running’. - Instrument fuses duly wired and feruled. - MCCB of suitable rating with overload and short circuit protections.

d) Genset Controller: - Control is microprocessor-based generator set monitoring and control system. The control provides a simple operator interface to generator set, manual and remote start / stop control, shutdown fault indication, and an LCD hours counter. The integration of all functions into a single control system provides enhanced reliability and performance compared to conventional generator set control systems. The control has been designed and tested to meet hars environment in which gensets are typically applied.
