Generators are the essential component in producing electric power. Usually driven by gas or steam turbines, they are used both in power plants and in industrial power generating facilities.
Siemens offers you a broad range of services tailored to your specific needs as operator of an air-cooled generator with an output of up to around 200 MVA.
You can profit from the extensive know-how and the historical experience of our Generator Product Competence Center (PCC) at our location in Essen, Germany, which over the course of decades has acquired and integrated many reputable generator manufacturers.
Our extensive service range offers you as the operator:
Regular maintenance is essential to preventing unscheduled production outages, complying with statutory regulations, and ensuring utmost plant safety and reliability.It enables incipient damage due to natural wear and ageing processes to be detected and eliminated at an early stage, before they can cause major harm.
Siemens offers you:
Siemens offers extensive electrical diagnostic measurements that give a meaningful, reliable picture of your generator's current condition, enabling accurate assessment of physical ageing and performance of service life analyses.
These monitoring capacities include:
Uprating and improving generator efficiency are two desirable factors that help to make your unit more profitable.
Siemens provides comprehensive assistance, from planning to recommissioning of your refurbished components.
Siemens offers you a broad range of upgrading and uprating options, including:
At its Product Competence Center in Essen, Germany, Siemens offers you specialized personnel and sophisticated cutting-edge manufacturing facilities for performing complex repairs and service activities.
The manufacturing facilities at our Essen location comprise:
This recently developed engineering approach combines the cutting edge in generator technology with the interfaces of legacy generator types while ideally catering to the operator's economic interests. The focus is on integrating state-of-the-art active parts as used in today's newly built units to engineer tailored replacement machines that will take over from the original machines within a foreseeable time frame.
These replacement machines are designed to mate with all relevant interfaces (i.e. shaft centerline height, foundations, etc.) of the legacy unit and to facilitate quick exchange.
The footprint approach can be applied to nearly all generators, irrespective of the model and type of cooling, and for all conventional designs on the 50-Hz and 60-Hz markets, for voltages of 6.3 kV, 10.5 kV or 13.0 kV.
Replacement of excitation system
The increasing cost and delivery times for replacement parts and servicing the generator's original excitation systems are economic incentives for upgrading. Replacing the original analog excitation systems with wear-free, state-of-the-art digital systems not only reduces running costs but also improves unit availability.
In a nutshell, our footprint approach offers the operator the following advantages:
