2MW Natural Gas Engine Generator Power Plant

2000GF10-T(2000kW) natural gas generating set are powered by model L20V190ZLT-1 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 "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.Engine Design
This natural gas generator adopts -L20V190ZLT-1 engine, which is one sort of highly intelligent, low heat consumption, high reliability, low emission, long lifetime 20V gas engine. L20V190ZLT-1 electrical control and external mix engine owns speed 1000r/min, single unit power 2200kW.
L20V190ZLT-1 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 genset 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.With large power reverse, the engine can be used to assemble 2000kW natural gas generator set and equipped machinery. It owns 40.4% generation efficiency, low maintenance cost and yearly 8000 running hours.

Characteristics of Control system                                    

1.American WOODWARD E6 control system
The E6 control system consists of hardware and software, including LECM controller,TecJet valve,ProAct valve,oxygen sensor and various other sensors. Software is a program installed in a computer that is connected to the hardware by a data wire. The operator controls the action of the hardware by operating the computer and sending instructions to the hardware.
2. Advantages of E6 control system:
E6 control system has perfect uniformity.Previous control systems include air-fuel ratio control system,speed regulation system,instrument monitoring system,ignition system and knock control system,etc. There are many kinds and poor uniformity. E6 control system integrates various independent control modules to realize various functions.
3.LECM controller is the control unit in E6 control system, which adopts the design method combining modularization and integration.
4.Modularization: LECM controller consists of three modules: main control module,EID module and auxiliary module. Each module has its own CPU and memory.
5.Integration: LECM controller can be used by two or three integration between the three modules. After integration, each module can share sensors such as speed and phase, and the data can be Shared through internal bus interconnection.
Characteristics of Control panel                                            
local control panel
Main functions of local control panel: The main configuration of local control screen includes: 15-inch touch screen (HMI), button, switch, indicator light, generator management module, network switch, etc.
HMI is mainly responsible for collecting and displaying the parameters of E6 control system,monitoring instrument,unit management module and generator excitation system. Starting,closing,loading and unloading of the unit can be controlled by HMI. Alternator management module can automatically check the synchronization, meet the requirements of grid-connected control, and can dynamically display the operation of the unit, with the measurement and protection of various electrical parameters of the unit, operation parameter query, alarm information query, historical data query and other functions, to ensure the safe and reliable operation of the generator set.
The local control panel is equipped with imported (COMAP, Heinz or Denver) automatic paralleling /grid module and paralleling/grid selective button, which is easy for users to adjust the power supply flexibly. If the paralleling function is selected, five sets may realize the automatic paralleling and automatic load sharing; if parallel function is selected, the automatic paralleling of single unit and the setting of system power can be realized. The automatic module is equipped with the LED display, with Chinese operation interface. The running status of whole system may be displayed realtime, with the functions of measurement and protection for various electrical parameters of unit and varies of running parameters, alarming information and historical data to ensure the safety and reliable running of generator set. The module has telecommunication interface.
The revolving speed and voltage of genset can be adjusted automatically by electronic speed control system and excitation system, and can also adjust the RPM potentiometers and voltage knob. The control panel is equipped with a float charging device, which can utilize the self-generation of the generator set to charge the battery that supplies power to the control panel.
The control panel may monitor the following parameters:
