To meet tourism demand in the autonomous region of Tibet, the Chinese government is launching a project to build a new airport for which Himoinsa has supplied three generators suited to the high altitude and extreme climatic conditions.
Himoinsa supplied three generators: two 3-phase, 50 Hz, 1060 kVA generators and one 50 Hz, 1900 kVA generator, incorporating Mitsubishi engines and Stamford alternators, a Deep Sea controller, battery charger, battery and cable system, preheating water jacket, oil pump, antifreeze and oil.
The generators are capable of starting up within seven seconds of a power failure and of providing more than 250 hours of continuous energy
The new airfield – also part of the national plan to increase economic investment in the area – is 4500 meters above sea level, in one of the most inaccessible areas in the world.
The construction and expansion of Xigaze Airport is one of the largest projects of China´s Civil Aviation Administration, and is regarded as part of National Plan 11 that the government has implemented to boost the economy. The airport has received an investment of 484 million Yuan and its construction has been under way for the last two years.
But the project faces the challenge of having a stable power source to provide a reliable and secure electricity supply in this inaccessible area. The altitude at which the facilities are located is the single most difficult factor hindering the construction and supply of power.
Weather conditions are also extremely harsh, with winter temperatures averaging 6.3 °C during the day, and about -20°C at night. There is also a wide fluctuation in temperature and potential rainfall of 422.2mm.
To achieve an optimal energy supply, the project required installation of generators for the emergency supply of electricity, mainly for airport lighting, terminal building construction and the headquarters building.
The airport environment required generators that could be quickly and easily started in adverse weather conditions; heavy-duty equipment with low energy loss at high altitudes, capable of providing a fast and efficient power supply. The characteristics of the airport made it necessary to have high power supply reliability with guaranteed 24-hour operation and 99% availability, ensuring the supply of electricity under extreme weather conditions
Himoinsa has supplied a product that meets project requirements and is also capable of working under extreme conditions with the quality typical of the brand. Himoinsa´s equipment has obtained a certificate of Quality Inspection and Supervision of Machinery at high altitudes above sea level, as well as an inspection report issued by the Center for Quality Inspection and Supervision of machinery at high altitude above sea level.

Cosworth and Rolls-Royce work on 2 kW generator
Cosworth has been contracted by Rolls-Royce Distributed Generation Systems to demonstrate the potential of its market-leading heavy fuel engine technology.
The companies have entered into a research and development agreement to further the development of Cosworth’s super lightweight engine technology for Rolls-Royce portable and mobile power systems. Systems will be targeted at land defence applications that need smaller, lighter weight solutions than are currently available.
Unlike lightweight heavy fuel engines offered by other suppliers, Cosworth’s engines use true compression ignition, which delivers unbeatable fuel efficiency, the ability to run on a wide range of heavy fuels such as diesel, JP5 and JP8 with varying cetane and octane ratings, and low maintenance.
Ryan Hood, business unit leader at Cosworth, said: “Cosworth is fully committed to a long-term relationship with Rolls-Royce.
“The current focus is on a 2kW ultra lightweight generator. The intent is to develop an affordable volume production engine that is around 70% less mass than currently available engines, with a better fuel consumption rate.”
Cosworth Group was founded in 1958. With headquarters in Northampton, UK, the company employs 350 staff across Europe, the USA and India.
GE’s TM2500+ joins ecomagination product portfolio
GE’s flexible, efficient, trailer-mounted TM2500+ aeroderivative gas turbine recently received ecomagination qualification for its ability to help power cities and industries during environmental, economic and emergency power challenges.
GE’s TM2500+ joins the FlexAero LM6000-PH, LM6000-PCe, LM6000-PF and LMS100 among GE’s growing list of ecomagination-qualified products.
When compared with the previous version, the TM2500, it provides customers with faster, more flexible distributed power generation by combining high efficiency, better fuel gas consumption and fuel flexibility, coupled with lower emissions in both the 50 and 60 Hz segments.
The TM2500+ is a workhorse in the global aeroderivative mobile fleet. With a GE Aviation CF6-6 engine at its core, the TM2500+ resides on two trailers and can provide up to 31 MW of power generation in days due to its unique roll-on, roll-off capabilities for air, ship or road transportation. It is the portable version of the LM2500+ aeroderivative gas turbine, which has been the backbone of the global fleet since it was unveiled in 1969.
“GE’s legacy of innovation and American ingenuity is showcased in the TM2500+,” said Darryl Wilson, president and chief executive of aeroderivative gas turbines for GE Power & Water.
“Our engineers took the successful TM2500 and drove lean, innovative processes to make it even better to meet the needs for fast, emergency or mobile power.”
GE’s two-trailer design was enhanced to include the LM2500+ engine, allowing for higher megawatt output and efficiency performance. The TM2500+ offers multi-fuel flexibility operating on either natural gas or liquid distillate fuels and is easily converted from 50 Hz to 60 Hz. It can reach full power in less than 10 minutes and is capable of achieving nitrous oxide (NOx) emissions down to 25 ppm with water injection.
GE’s TM2500+ aeroderivative gas turbine operating on natural gas at ISO baseload conditions has an efficiency of 37 per cent at 60 Hz and 35 per cent at 50 Hz with water injection for NOx control.
To earn ecomagination qualification, a product is evaluated for its ability to significantly and measurably improve the customer’s environmental and operating performance.
Green Order, a consulting firm, helps verify the rigorous, multi-tiered qualification process to ensure accuracy and thorough documentation of technological performance.
At 60 Hz and when compared to GE’s TM2500 aeroderivative gas turbine operating at ISO baseload conditions, the TM2500+ emits approximately 5700 fewer metric tonnes of carbon dioxide (CO2) per year at 30 MW of output, equivalent to the annual CO2 emissions of approximately 1120 cars on US roads.
MWM introduces a new version of its TCG 2032
After two years of constant development, the new version of the TCG 2032 (the largest MWM genset) was launched in January 2012.
Optimized spark plugs and turbocharger technology have resulted in electrical efficiency of up to 44.2 per cent with an output of 3333 to 4300 kWe (in the V12 and V16 cylinder versions). Thanks to excellent operational experience, the period of operation up to the major overhaul has been increased from 64 000 hours to 80 000 hours.
After the successful launch of the TCG 2020K in April 2010, MWM extended its product range in the autumn of the same year to include the TCG 2020K1 system, which delivers up to 1,000 kWe. This new genset with electrical efficiency of up to 40% can be operated with natural gas under many different environmental conditions. It combines low operating and maintenance costs with the dynamic load response capabilities and robustness of the tried and tested TCG 2020K series. Customers are thus guaranteed an excellent price-performance ratio and a shorter amortization period. Furthermore, nano-coated intercoolers also improve operational safety when the intake air is of poor quality.
MWM recently launched an improved TCG 2016 C which can also be used with biogas. It is available for both 50 and 60 Hz. The TCG 2016 C series is available in the V8, V12 and V16 versions. Systematic optimization of the ignition and the TEM (Total Electronic Management) control system guarantee improved load balancing over all the cylinders. The anti-knocking controller has also undergone further improvement. The combination of optimized throttle valves, a new actuator for the gas mixer and a nano-coated intercooler ensures that the genset lasts even longer and is even less sensitive to external influences.
Thanks to these improvement measures, the new genset achieves a maximum efficiency of 42.8% with biogas.
