Operation Strategy of Electric Motors for Water Pumping On Malang City Regional Water Supply Company (Pdam Kota Malang) For Electrical Energy Efficiency Improvement
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 3
Abstract
PDAM Kota Malang (Malang City Regional Water Supply Company) has several pumping stations that operate the water pump motors 24/7 with no breakdown period, while others operate the motors in rolling breakdown timing. Badut Pumping Station, Sumbersari Pumping Station, Supit Urang Pumping Station, and Istana Dieng Pumping Station use no breakdown period, since those utilize single or dual unit of motors. Wendit Pumping Station and Mojolangu Pumping Station use rolling breakdown timing, which using seven out of nine, or four out of six, available pump motors. In rolling breakdown timing, each pump motor operates in 1,000- hour start-and-stop sequence. This study analyzed the electrical energy consumption as well as water production, with the pipeline infrastructure and water reserving system excluded. The energy is limited to the PLN (state electrical company) source, regardless of every pumping station owns their diesel generator due to reliability of PLN as electrical power source. This study is based on assumption that lighting usage is negligible. Efficiency of the electrical energy usage is where this study focused on. Variables involved are mainly about power quality, power factor, motor efficiency, and the ratio of energy consumption on water production (specific energy consumption). Finally, the expected result of this research is to provide useful recommendation for PDAM Kota Malang about the energy consumption efficiency and water production management
