Mobile Dual-Fuel Power System
Cat power plant allows switch between diesel, gas; no recalibration required
Caterpillar Inc. has introduced the XQ2000 power module with dynamic gas blending (DGB) system, the company’s first integrated dual-fuel mobile power plant.
Designed for use with the 50 Hz XQ2000 power module driven by the Cat 3516B engine, the DGB advanced control system automatically adjusts to changes in incoming fuel quality and pressure. Cat said the engine can run on a wide variety of fuels, from associated gas to vaporized liquefied natural gas (LNG), with no loss of performance integrity.
The DGB solution includes the EMCP4.3 and AGC-4 paralleling controller, which integrates the engine, generator and gas blending system.
Additional features of the control system include multiple operational modes; base-load, power factor, load sharing and synchronization controls; auto start/stop control and generator circuit breaker control; engine protection shutdown/startup ability with custom programmable alarms; SCADA and plant level control systems compatibility; fuel level indications and alarms; fuel tank fuel transfer control; voltage and frequency adjustment; plain text display of fault codes; and compatibility with the company’s Product Link remote monitoring solution
The XQ2000 with DGB will be available for shipment in the third quarter of 2014 through the global Cat dealer network and designated international power projects (IPP) providers to meet short or long-term power demands, the company said.
