Project

The Guangdong Qingyuan Pumped Storage Power Station in Qingyuan City was constructed for China Southern Power Grid by the Guangdong Hydropower Planning & Design Institute. The power station represented an investment of USD 0.8 billion and has an installed capacity of 1,280 megawatts. It consists of four vertical, single-stage, reversible, mixed-flow pump turbines – with single unit capacity of 320 megawatts – in underground factories.

Solution

Using Bentley software, the Institute constructed a sophisticated 3D model of the power station that was used to perform multidiscipline clash detection and resolution, optimize and improve the design, and guide construction work, especially for the complex network of underground cabling on this project. The labor-intensive and costly challenge of laying cable was managed with Bentley Raceway and Cable Management, which did 80% of the work in choosing the length and path for all the cables.

Outcome

This power station will adjust power supply peaks and valleys, modulate frequencies and phases, and serve as a standby station under emergency conditions. Guangdong Hydropower Planning & Design Institute realized substantial benefits from applying Bentley technology to the cable management on this project, including a one-month shorter schedule, a 90% reduction in errors, and a 60% reduction in labor costs. In addition, the use of ProjectWise made multi-discipline collaboration as much as 20% more efficient.

Software

Bentley’s collaborative platform was used to optimize the design process, improve project quality, enhance design efficiency, reduce design cost, and facilitate communication with the owner. Products implemented on the project included OpenBuildings Designer, OpenCities Map, OpenRoads, MicroStation, OpenPlant, ProjectWise, Promis.e, ProSteel, Bentley Raceway and Cable Management.
