VISUALIZATION SYSTEM OF A HYDRO-ELECTRIC GENERATING UNIT AND ITS OPERATIONS
Yitao Chen · Proceedings of the CSEE · 2005
In order to reduce the equipment downtime and the maintenance cost, the maintenance strategy in hydro power plants have to be progressively changed from time-based maintenance (TBM) to condition-based maintenance (CBM). Correct analysis and diagnosis on the basis of the collected information is essential for right maintenance decisions. Visualization Decision Support System (VDSS) of HGU is presented, which focuses on the applications of virtual reality on HGU, with 3D modeling technique adopted in this system. Besides the paper describes the virtual reality and the interaction of HGU 3D modules. The visualization can be performed in the virtual reality where the action is driven by the system information acquired from real units. This developed system can provide vital indications about the HGU equipments condition, and give warnings of latent problems. This greatly improves the understanding of a Hydroelectric Generating Unit (HGU) and its operations, especially their mechanical interactions. This tool is also extremely valuable for the training of maintenance engineers.
