| Popis: | Geothermal power plant (GPP) technology is one of the prospective renewable energy technologies and a priority in the development of national electricity today. The Electricity Supply Business Plan (RUPTL) 2018-2027 shows the plan to increase GPP capacity in the period of 4.583 GW, or 8% of all national power plants development, and 30% of all new & renewable energy-based power generation. Until 1st quarter 2018, the installed GPP capacity of 1.924 GW and all of them are imported technology. So efforts to develop national GPP technology are very strategic to support national energy independence in the future. AgencyfortheAssessmentandApplicationof Technology(BPPT) has developed and operated a 3 MW GPP of condensing type technology in Kamojang - Indonesia, which is the first prototype GPP manufactured by national company. The GPP design is based on KMJ-68 well data characteristics, owned by Pertamina Geothermal Energy, and steam turbine specifications designed in reverse engineering. The manufacturing process of the main components of the plant such as turbines, generators, condensers, etc. carried out by the national industry. In this paper it is discussed about the process of test operation in the early stage, starting from the preparation of SOP, conducting free load generator test, dummy load testing, and load testing. Until early 2018, the BPPT’s GPP has generated 15,572 kWh of electricity, with the highest load of 1.3 MW. During testing all process parameters, particularly vibrations, bearing temperatures and lubricants, all within safe limit. The thermal efficiency of the turbine-generator system reaches 13% for loads of about 1 MW. |
