1000kW Natural Gas Generating Set 1. Description of Generating Set 1000kW natural gas generating sets(1000GF-TK2) are powered by model AD12V190ZLT2gas engine produced by our company. Complying with National Standard “GB2820 General Specification for Industrial Frequency Diesel Generating Sets” and with reference to “IEC34-I” rotary generator standard, the sets are equipped with high quality alternator of both home & abroad and self-made control panel according to customers requirement. AD12V190ZLT2natural gas engine is adopted advanced governor of American WOODWARD Company. It is the engine that mixes air and fuel before turbocharger. The power performance, fuel economy and reliability of the gas engine reach world advanced level by adopting world advanced outer mixing mode, electronic control technology and lean-burnt strategy. This 1000kW gensets h--e the features of accurate voltage regulating, good dynamic performance, less voltage w--eform distortion, high efficiency, compact structure, easy to maintain, low speed, reliable and long life operation and cost-effective. The 1000kW gensets can either transfer electricity directly to load or be co--ined in a power station with two or more than two sets. They can be used as normal and stand-by power in oil field, factory, resource development base, etc 2.

Control Panel Control panels for diesel generating sets are used to control the electric energy transporting of generating set. They h--e the functi--- of under-voltage, over-current, auto speed governing and reverse power protecti--- etc. Meanwhile, they can monitor the speed, water pump, oil pump, oil pressure and exhaust temp of the engine. And also they are fitted with sound and light alarm devices. 5.
