    Parametric Design Application of Hydropower Engineering

Project Summary

Project
On the River Ntem in Cameroon’s South Region, the Memve’ele Hydropower Station will have a total installed capacity of 211 megawatts with four single-capacity units of 52.75 megawatts and a water reservoir of 82.71 million cubic meters. Designing a reasonable layout scheme was key to the success of this USD 637 million project.

Solution
The station was designed by Beifang Investigation Design & Research (BIDR) using ProjectWise as a collaboration platform, and MicroStation and AECOsim Building Designer for 3D modeling. This environment ensured the use of common standards, simplified configuration management, and enabled comparison of multiple layout schemes. GenerativeComponents was used to explore designs for hydraulic machinery components such as the spiral case and draft tube.

Outcome
The efficient parametric modeling process enabled BIDR to master the layout for this geographically complex station. Modeling saved time and eliminated bottlenecks in the design process. Templates for components such as the spiral case, draft tube, and arch dam freed the engineers for more valuable and creative work. Overall, Bentley solutions shortened the design cycle from three months (using traditional 2D design) to one month, saving about USD 150,000.

Software
In addition to AECOsim Building Designer, Generative Components, and ProjectWise, BIDR applied GEOPAK Civil Engineering Suite for site design and excavation, Bentley Substation for electrical design, and Bentley Navigator for collision detection and review. Developed within the Bentley environment, the 3D information model allowed the engineers to quickly and accurately design the layout of the power plant equipment and adjacent environment.
Outcome/Facts:
  • Common components applied to the 3D information model will serve as design templates on future projects.
  • The 3D information model of the station will be crucial to construction, operation, and maintenance.
  • The arch dam was also modeled in Generative Components, with finite element calculations recorded in Excel for quick modification.
