The Development of Trash Diverter System for Tenom Pangi Hydro Power Station Intake, Sabah

Hazha Bin Abdul Hamid and Mohd. Khairul Zaki Bin Abdullah

Abstract:
Clogging of water intakes caused by accumulation of floating trash is a common problem experiencing by many run-off-river hydro power plants. Tenom Pangi Hydro Station is significantly affected by it which leads to reduction of power generation or sometime station shutdown. A trash diverter system was developed to prevent the clogging and to accommodate existing station operational constraints. The development involves mainly a brainstorming session to finalize the conceptual design, and computer modeling. Commercial computational fluid dynamic program was utilized to create computer model to analyse and evaluate the river flow characteristics due to trash diverter installation in order to determine the trash diverter location for effective diversion of trashes and minimum flow resistance into the water intakes. Finite element analysis program was used to do stress analysis on the trash diverter structure. The power station requirement, the design of existing water intakes from other local hydropower and water treatment plants were also considered in finding the effective solution. The results from the modeling and analysis were used to establish preventive measures for preventing existing water intakes clogging and specification for the construction of the trash diverter system.
