Engine & Turbine Technology
Te power supply challenge is most acute in the city of Istanbul, where one fifth of the nation’s population is located.
Loss of systems data A large number of businesses and residents use Türk Telekom’s services – the consequences of a loss of systems data for these customers would be devastating. In order to update its systems, the company replaced the existing emergency power gensets at its Istanbul headquarters. Since July 2011, three Type DS 2595 D5S emergency gensets from MTU Onsite Energy powered by three Type 16V 4000 G63 diesel engines produce 5,190kVA of electric power. Following a market demand analysis for the Turkish communications network, Türk Telekom chose MTU Turkey to completely equip their 144 sq metres underground facility. MTU supplied everything from gensets through switch cabinets to electrical plant and also ensures that the manager receives a text message as soon as a power outage occurs and the gensets have started up. Prior to installation, the units were subjected to
comprehensive and thorough tests involving simulated load imposition on the engine manufacturer’s own test stands at its headquarters in Friedrichshafen. Te gensets run in parallel and each can serve as a back-up for the other. Teir high torque means the engines have rapid and high load imposition capability
Energy systems analysis A
nalysis of power generation or combined heat and power (CHP or cogeneration) systems as an essential aid to the selection of equipment. Analysis will include performance under design and off-design conditions (eg, the effects of part-load operation), the duration of each required condition and control philosophies necessary to achieve such objectives as maximising revenue, minimising fuel consumption, minimising
carbon emissions or making best use of renewable energy. Energy systems comprise
a range of features such as gas turbines, reciprocating engines, steam turbines, heat exchangers, generators and cooling systems. Amongst an array of
design decisions, all of which impact on both performance capital cost, are prime mover performance or efficiency, boiler efficiency, live steam conditions (possibly multiple pressures), condensing pressure, cooling system type and performance, steam extraction pressure for heating (CHP), and possibly absorption cooling (CCP or CCHP), thermal storage, variable flow circuits and condensing heat recovery.

and can achieve operating status, stable voltage and frequency, within nine seconds. Load can be imposed from this point on. Türk
Telekom’s central facility needs around 2,200 kVA of energy per hour. Tirty-three per cent of Turkey’s Internet volume emanates from here. Te station is Türk Telekom’s third biggest in the country and the company has a total of around 5,000 individual stations which are gradually allowing it to adapt to the ever expanding telecommunications scene. Türk Telekom’s use of emergency power technology
from MTU Onsite Energy is not limited to Istanbul. At its location at Erzurum in the east of the country the company has installed two MTU gensets with Series 2000 engines. MTU Onsite Energy is a brand of Rolls-Royce
Power Systems AG. It provides diesel and gas-based power system solutions: from mission-critical to standby power to continuous power, heating and cooling. MTU Onsite Energy power systems are based on diesel engines with up to 3,400kW power output, gas engines up to 2,150kW and gas turbines up to 50,000kW. l

Ultimately the majority are a matter of
choice, but careful analysis is essential to identify where extra design effort and capital investment will bring the most financial, regulatory or environmental benefit and, conversely, where theoretical benefits may be outweighed by issues of practicability, operability and ease of procurement and construction. l
