Whether they are due to storms, operating failures or unstable grid systems, temporary outages in public power supply systems are becoming ever more frequent. And when they happen, we depend on on-site power generators to swing into action within a few seconds to restore power and prevent injury to people, damage to property and extensive economic losses.
Under the umbrella of its ’MTU Onsite Energy’ brand cluster, Tognum provides a wide range of diesel and gas-based systems for emergency power generation. These systems can supply everything from smaller premises such as banks or clinics, to entire city districts or nuclear power stations. In addition, MTU Onsite Energy also provides mobile, ready-made and pre-tested container-gensets. These versatile units can be rapidly relocated from one site to another and are capable of generating the power needed less than 15 seconds after receiving the start signal.
At particular times of the day or on particular occasions, demand peaks require increased power generation. On-site system solutions in the Tognum Group’s MTU Onsite Energy program have been specially developed to do just that. In peak load periods, these diesel or gas-driven units can be relied on to supply the power needed and to supply it fast.
Peak load demand can be covered either by feeding power into the public grid (grid parallel operation) or by supplying individual consumers direct (island operation). It may involve a single genset or several units connected in parallel but whatever the configuration, the demands placed on the diesel engine and generator control systems are extremely high, especially with regard to frequency and load stability.
In conjunction with its high-precision diesel engine control system, MTU Onsite Energy also provides custom-tailored control components developed to ensure that operators can be sure of maximum reliability, precision and user-friendliness.
Continuous power generation requires the highest levels of reliability and economic efficiency in equal measure. The Tognum Group’s ‘MTU Onsite Energy’ brand includes diesel and gas-powered generation units which are precisely engineered for this purpose.
MTU diesel gensets are in operation around the world and around the clock, ensuring decentralized power supplies to even the remotest consumers such as desert mining locations.
Many of MTU Onsite Energy’s varied continuous power generation solutions work on the cogeneration (CHP) principle, a particularly environmentally-friendly technology for the combined production of heat and electric power.
CHP plants powered by gas engines utilize natural gas or biogas (amongst others) to generate heat and power for industry as well as for commercial premises and public buildings such as swimming pools and hospitals. They are also in operation utilizing biogas in agricultural applications and at sewage plants and refuse sites.
Gas turbine plants likewise exploit the advantages of cogeneration. At peak performance they can generate enough power to supply around 100,000 households continuously with electricity and around 10,000 single-family homes with thermal energy.
Electronically-controlled high-pressure injection is a key technology in the field of low-emission, low-consumption diesel engines. Cutting-edge systems from L’Orange, the Tognum Group’s injection specialists, make it possible to combine low pollution levels with low fuel consumption – and long service life.
L’Orange was the first company to introduce this key ‘common rail’ injection technology in large diesel engines and it has continued to maintain its lead in the sector. The system involves the high-precision injection of fuel from a common high-pressure accumulator into the cylinders and allows significant reductions of emissions and fuel consumption in diesel engines.
