PERFORMANCE ANALYSIS OF A WIND TURBINE WITH PERMANENT MAGNET SYNCHRONOUS GENERATOR

摘要

This paper presents performance analysis of a 2 kW wind turbine with permanent magnet synchronous generator. The Government of the Republic of Indonesia through the Ministry of Energy and Mineral Resources (ESDM) targets by 2025 of at least 23% of the total national electricity supply comes from renewable energy sources. Government programs must be supported by all regions to help build renewable energy power plants to its potential of each. In this case, the district of Bantul, Yogyakarta Special Region Province, Indonesia, particularly the southern coastal region is very likely to be developed wind power plant. In this research, the create-designing and testing of wind power with maximum capacity of 2 kW is done. The test has been carried out on September 5 and 6, 2016 at the Baru Beach, Srandakan, Bantul. The test results on September 5, 2016 showed that the highest power generator occurred at 12:40 PM is 768.96 watts, with a wind speed of 8.76 m/s, AC voltage of generator is 40.00 volts, the DC voltage generator after rectified be 53.40 volts, and the load current is 14.40 ampere. In this condition, the 2 kW wind turbine has the efficiency of 38.4%. Furthermore, the test results dated 6 September 2016 found that the highest power generator at 10:50 PM is 842.20 watts, with a wind speed 9.53 m/s. At this peak condition resulting AC voltage of generator of 39.00 volts, the DC voltage of 49.60 volts, the load current of 17.00 amperes, and resulting in efficiency of 42.1%. The research results indicate that wind turbine is an alternative solution in the southern coastal region of Bantul for the supply of renewable energy sources.
