Amount

Supplying, Installation, Testing and Commissioning of 50 KVA 140KW at 0.8 power factor, 415 V, 50 Hz, Silent D.G.set conform to ISO 8528 specification and should meet CPCB norms complete as detailed below:-

Ø DIESEL ENGINE:

CUMMINS make engine model 4BTAA3.3-G11, 4 cylinders , inline, 4 stroke cycle, Water cooled turbo charged after cooled, developing 84 BHP at 1500 RPM under NTP conditions of BS:5514. The engine shall be provided with electrical starting arrangement & shall give the electrical output of 50KVA/40KW at 0.8 power factor, 415Volts at the alternator terminal.

Ø ALTERNATOR:

Stamford make single bearing alternator suitable for continuous operation generating 50 KVA at 1500 RPM, 415Volts , 0.8 power factor (lag) suitable for 50 Hz, 3 phase, 4 wire system, confirming to BS 5000/ IS 4722. The alternator is brushless type, screen protected , revolving field, self excited, self regulated through an AVR. The alternator has the following features:

Ø + 1.0% voltage regulation (max.) in static conditions

Ø IP: 23 protection with insulation class H

Ø Permissible overload of 10% for one hour in 12 hours of operation.

Ø 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:

A. PS0500 Controller

B. Aluminium Bus Bars with suitable capacity with in/outgoing terminals

C. Indicating Lamps for 'Load On' and 'Set Running'

D. Instrument fuses duly wired and ferruled

E. MCCB of suitable rating with overload and short circuit protections.

PS 0500: Genset Controller:

Cummins PowerStartTM PS0600 control is a microprocessor based generator set monitoring and control system The control provides a simple operator interface to the generator set, manual and remote start/stop control shutdown fault indication, and an LCD hour 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 harsh environment in which gensets are typically applied.

Features, Functions, Protections

16 character x 2 line alphanumeric LCD display with LED backlight

Operator interface

Provide a record of most recent fault conditions. Fault history stored in the control non volatile memory

Provide Alternator data

Voltage (line to line and line to neutral voltage) -Current (1 ph or 3 ph) -kVA (3 ph and total)-Frequency

Provide Engine data

Starting Battery Voltage Engine running hours Engine Temp.Engine oil pressure

Control includes provision for Service adjustment and calibration of DG control functions.

Engine controls

§ Power Start operates on 12 VDC batteries

§ Auto start mode accepts a ground signal from remote devices to automatically start the DG set. The remote start will also wake up the control system from sleep mode.

§ Engine Starting - The control system supports automatic engine starting, Primary and back up start disconnects are achieved by battery charging alternator feedback or main alternator output frequency.

§ Controller provide configurable time delay of 0-300 sec to start after remote start signal and time delay of 0-600 secs prior to shutdown after stop signal.

§ Sleep mode increase battery life. Configurable current settings from low to minimize current draw when genset is not working.

Engine Protective Functions includes

ù Configurable alarm output

ù Emergency stop: Annunciated whenever an emergency stop signal is received by the control.

ù Low Lube oil pressure warning and shutdown

ù High engine water temperature warning/ shutdown

ù Low coolant temp warning

ù Sensor failure indication

ù Low and high battery voltage warning

ù Weak battery warning

Ù Fail to start shut down

ù Cranking lockout: Control will not allow the starter to engage or to crank the running engine

ù Cyclic cranking : Configurable for the number of starting cycle (1 to 7) and duration of crank and rest periods.

Alternator Protective functions includes

ù High and Low AC voltage shut down

ù Under and over frequency shutdown / warning

ù Loss of sensing voltage input shut down

ESSENTIAL ACCESSORIES:
