Xianning Chibi 500-kilovolt Substation is a key project in Hubei that will meet Xianning’s power load growth demand, optimizing the power grid to improve power supply reliability. The project presented complex topography, requiring a compact layout, compounded by a short construction period. Faced with coordinating multiple engineering disciplines, POWERCHINA realized that traditional workflows were insufficient to timely deliver the project within budget. Aiming to achieve full lifecycle digitization, they needed integrated 3D/4D modeling and digital twin technology.
POWERCHINA selected Bentley’s 3D/4D modeling and iTwin applications to establish a collaborative digital design environment, 4D visual construction methodology, and a full 3D substation digital twin. The integrated technology solution reduced the project footprint by 0.97 hectares, minimizing farmland impact and saving CNY 2.84 million in costs. Working in a coordinated design and construction management platform, the team avoided more than 50 reworks, reducing the construction period by 30 days. The digital twin facilitates real-time asset insight and smart substation management, setting a benchmark for digitization of the State Grid.
