1200kW Natural Gas Generator Silent Type

Description

1200kW Natural Gas Generator Silent Type

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.
