1000 MW Turbines in Shougang Power Plant
Elastic Support of two 1000 MW Turbines in Shougang Power Plant, China
Shandong Shouguang Power Plant is located in Yangkou town, Shouguang county-level city of Weifang city, Shandong province. It includes two ultra-supercritical coal fired turbine generator units. The
turbine foundation length is approx. 46 m, width 16 m at turbine side and 11 m at generator side. The turbogenerator sets are supported on a vibration isolation system. Total spring supported weight amounts to about 5000 metric tons for 1 unit.
- Turbine manufacturer Shanghai Electric Power Generation Equipment Co. Ltd Turbine Plant
- Turbine type N1000 with Siemens technology
- Generator type QFSN-1000
- Supplied by Shanghai Electric Power Generation Equipment Co. Ltd Generator Plant
Challenge
The seismic input (see figure right) required a detailed investigation of the complete structure. The usual turbine hall layout considered a direct substructure below the vibration isolation system and parallel columns, supporting the adjacent structure. Space for piping arrangement was limited – thus, an optimization of the layout was required. A conventional machine building requires significant space for placement of all machinery and equipment. The first idea of an elastically uncoupled machine foundation was even not enough to satisfy all conditions. The integration of the substructure into the machine building became necessary, but local project partners and designers had no experience in this context so far. Technical exchange with GERB experts was essential to overcome all upcoming challenges.
Solution
The reinforced concrete deck is supported on Spring-Viscodamper® combinations. The substructure below the elastic support system is integrated into the adjecent machine house structure. The columns (see picture on the right) are supporting not only the spring devices, they also support upper floors. This integration improves the overall seismic behaviour of the structures and optimizes the required space (e.g. for pipework systems), which is very valuable in a power plant.
3-D Finite element analyses are performed for the dynamic and static analysis of the important machine foundation as well as the connection and integration interfaces.
Result
The project was completed in 2014 and unit one began operating in July 2016, unit 2 in November 2016.
Achieved advantages:
- Substructure integrated with machine building (first application of this type of layout time in China)
- Improved behaviour of the building and machine foundation during seismic events
- Space-savings (area of substructure) and cost reduction for construction
