    Automation and Integration of Substation Design Work for 230-kilovolt Project

    Kratie and Kampong Cham, Cambodia

Project Summary

Project
Diamond Power Limited awarded a contract to PESTECH International Berhad to design, supply, erect, and commission a substation and transmission system from the town of Kratie to the city of Kampong Cham, Cambodia. The organization is charged with performing the transmission portion and the primary and secondary design of the substation system for the USD 92.2 million project. Once the project is complete, PESTECH will undertake a 25-year contract to operate and maintain the power transmission system.

Solution
PESTECH planned, designed, engineered, manufactured, tested, delivered, installed, and commissioned the 230-kilovolt switchyard in the Kampong Cham substation, the new Kratie substation, and the interconnecting 230-kilovolt duplex ACSR bittern transmission line. Doing this efficiently meant replacing its usual manual design process with Bentley Substation, which provided an integrated platform for 2D electrical and 3D physical substation design. Working with Bentley Channel Partner Hertford MES Sdn. Bhd., the project team also implemented ProjectWise, MicroStation, and Navigator to enhance productivity, facilitate collaboration, minimize errors, and enforce standards.

Outcome
The substation will extend the lifespan and reliability of customers’ transmission and distribution assets and support the fast-developing region’s transportation and building infrastructure. Using Bentley applications enabled the team to cut design work from weeks to days, saving an estimated 70 percent in project time. Schematic drawings that normally take 14 to 21 working days were completed in less than seven working days, and cable schedules that usually take three days to check and document were automatically generated in one hour or less.

Software
Bentley Substation provided the engineering team with a single platform for a unified 3D design environment. It also acted as an intelligent database, eliminating manual data reentry and manual coordination while facilitating cross-discipline collaboration, which minimized errors and rework, and enabled a truly intelligent design. This database also helped the team automate much of the design process – especially the creation of drawings and reports. ProjectWise facilitated document sharing, design collaboration, faster reviews and approvals, and mobile design access.

Outcome/Facts
  • ProjectWise facilitó el uso compartido de documentos entre departamentos y equipos de diseño, simplificando las tareas de comprobación y las revisión del diseño.
  • PESTECH reemplazó el proceso de diseño manual utilizado en proyectos anteriores con Bentley Substation que proporcionó una plataforma integrada para el diseño de subestaciones eléctricas y físicas.
  • Las aplicaciones de Bentley permitieron al equipo reducir el trabajo de diseño de semanas a días, ahorrando un estimado del 70 % en tiempo de proyecto.
  • PESTECH operará y administrará el sistema de transmisión de energía durante 25 años garantizando el buen funcionamiento de Diamond Power.
