1200KW Baudouin Natural Gas Electric Generator CHP Cogeneration
Power Generator
Description
Gas Generators
Weichai 16M33D1280NG gas engines and mecc alte ECO46 alternators
are selected. In one canopy, one 1.2MW gas generator, one
horizontal cooling system and one control system are integrated.
The canopy is sand and catkin proof. The temperature zone control
design enables the generator be normally operated at temperature
range -30℃ to 50℃.
Total power plant capacity is 12MW and all generators are combined.
Any of the generators can be backup set which enables urgent shift
of any other generator. An isolate switch is installed for each of
the generator which will isolate any gas generator when necessary.
Generator Model: EW-1200NGB-1/4A.
1.2MW Gas Generator Design
Canopy
The 30-feet long canopy is exclusively designed for the 1.2MW
generator. The surface is coated by polyurethane which is shining
and wear-resisting. In the canopy, there are control cabinet,
generator cabin, air inlet/outlet filtering system. On the top of
the canopy, there is horizontal cooling system. Gas supply is set
at one end and power cable is connected from another end. This
layout makes site gas pipe and cable arrangement easy and
convenient.
Gas Engine
Baudouin 16M33D1289NG gas engine is selected. The gas engine is
deeply developed in fuel control systems to improve its electric
efficiency, reliability and fuel adaptivity for certain working
conditions. The development also give consideration for dynamic
responsiveness, fuel economy, reliability and safety.
Proven gas engine is controlled by imported gas close-loop
lean-burn control system which includes latest Woodward control
system, Hoerbiger intelligent ignition system, ABB high efficient
turbocharger, single cylinder in-dependant compactive ignition,
electrical speed regulating system, fuel close-loop control system,
environment self-adaptation system and self diagnose and protection
system. All these systems will ensure accurate and reliable control
of gas engine and ensure its economic, dynamic and environmental
performances. The systems are also optimized by our company to
achieve high reliability and efficiency.
Cooling System
High-low temperature horizontal cooling system, high efficient, low
power electrical fans, inter-cooler and jacket water cooling
capacity close-cycle control are equipped to enable the generator
being used in different ambient temperature.

Alternator
Mecc Alte ECO46 brushless synchronous alternating-current generator
with strengthen moving components is selected to improve the
alternators resistance to load impact and interference and to
ensure its long term reliable and stable operation.
Generator Set Control System
Generator control system is DEIF intelligent generator control
system which realizes automatic start, speed up, switching on,
parallel, load allocation, brake separation, cooling and halt.
Remote control and monitoring system is also available.

1. The data is based on heat value on or above 35.88MJ/Nm3 natural
gas which conform to ISO8528/1, ISO3046/1 and BS5514/1 standards. | ||
The gas generators are started by 24V DC battery. No other diesel generator or grid power supply needed.
There are manual emergent stop and automatic failure emergency stop in the cases of natural gas leakage, overcurrent etc.
One-button control, air-fuel ratio auto adjustment, power factor
auto control, automatic load increase and decrease can be realized
on the generator.
Generator Control System: The control cabinet has one displayer. In
the cabinet, there are controllers, relays, fuses, meters,
adjusting buttons, indicators and emergent stop button to monitor
and control the generator’s working process.
The control system has protection functions and sound/light
alarmings for over load, over current, short circuit, reverse
power, underfrequency, overfrequency, undervoltage, overvoltage,
over speed etc.
For slight failures like high temperature of cooling water, low
pressure of lubricant, over load, fail startup, there will be light
and sound alarming and auto or manual stop is allowed.
For severe failure like high temperature of engine, low lubricant
pressure, over speed etc, it will stop automatically and alarming
will be sent out.
Guarantee period will be 12 months from EXW date or 3000 hours of operation, whichever comes first. Manufacturer will provide gas generator user manual and train buyer’s engineers. Any damages caused by misoperation or improper operation shall be responsibility of buyer.
