Automatic Voltage Regulation 1200kW Natural Gas Generators Electric Governor 3 Phase 4 Wire
Automatic Voltage Regulation 1200kW Natural Gas Generators Electric Governor 3 Phase 4 Wire
1. Description of 1200kW Natural Gas Generating Set:
1200kW natural gas generating sets(1200GF-T1) are powered by model H16V190ZLT-2 gas engine produced by our company. Complying with National Standard “GB2820 General Specification for Industrial Frequency Diesel Generating Sets(eqv ISO 8528)” and with reference to “IEC60034-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.
LE16V190ZLT-2 natural 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 1200Kw gensets have the features of accurate voltage regulating, good dynamic performance, less voltage waveform distortion, high efficiency, compact structure, easy to maintain, low speed, reliable and long life operation and cost-effective.
The 1200Kw gensets can either transfer electricity directly to load or be combined 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

4. Control Panel
The DSE7510 is an Automatic Engine Control Module, designed to provide advanced load share functionality for diesel and gas generating sets that include electronic and non-electronic engines.
The module’s load share functions
include automatic synchronising with built-in synchroscope and closing onto dead bus. Direct and flexible outputs from the module are provided to allow connection to the most commonly used speed governors and automatic voltage regulators (AVRs).
5. Main Specification of Engine
Note: Rated power is the effective power of engine at rated speed under standard environment conditions, according to the standard of GB/T 6072 (idt ISO 3046). The standard environment conditions are: atmospheric pressure: 100kPa, relative humidity: 30%, ambient temperature: 25 degrees Celsius, low heat value of gas: 36MJ/Nm3, max. load,. Otherwise, the engine power shall be corrected through conversion. MN≥80.
