Muscat Electricity Distribution Co. engaged Toshiba Transmission & Distribution Systems Asia (Toshiba) to customize, integrate, design, supply, and deliver 11-kilovolt, air-insulated switchgear for the Al Khoudh and Al Hail substations, the two primary power distributors for Sultan Qaboos University, the Palace of Oman, and Qaboos University Hospital. The USD 735,515 project required Toshiba to address unique operational, interlock, and protection schemes for the switchgear system to optimize power supply reliability. To meet these complex challenges, Toshiba needed flexible and accurate electrical system design software.
Toshiba relied on MicroStation and Promis.e for the secondary schematic control circuit design consisting of 50 panels of distribution switchgear for both substations. The automation and customization functionalities of Promis.e enabled Toshiba to expedite design and production of drawings, accurately extract devices for bills of material (BOM) and issuance of purchase orders, and minimize errors to optimize and reinforce power supply reliability to the Muscat regions.
Using Promis.e Toshiba accelerated project delivery, reducing wiring rework by 30 percent and troubleshooting by 25 percent. The ability of Promis.e to generate accurate, customized BOM reduced project costs by 20 percent. Bentley’s interoperable software accommodated various file formats facilitating information mobility and enhancing collaboration with the mechanical team and the client. With Promis.e providing high-accuracy deliverables, Toshiba expects a 10 percent ROI within 18 months of the substations’ operations, and a 50 to 60 percent ROI once the solution reaches full maturity.
Developing an intelligent model capable of cross-referencing schematics using Promis.e, Toshiba reduced drawing production time by 25 percent. The batch printing function in Promis.e reduced printing time by 50 percent while the ability to automate BOM quantity takeoffs with zero error improved device purchasing efficiency, saving significant time and money. Using Bentley software enabled Toshiba to design a state of the art secondary control circuit protection scheme that will ensure continuous power supply vital to the rapid development of Oman.
