Performance Analysis of a 2 kW Wind Turbine in the Southern Beach of Bantul

Abstract

This paper presents performance analysis of a 2 kW wind turbine in the Southern Beach of Bantul. The Government of the Republic of Indonesia through the Ministry of Energy and Mineral Resources targets by 2025 of at least 23% of the total national electricity supply comes from renewable energy sources. 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, 2015 at the Baru Beach, Srandakan, Bantul. The test results on September 5, 2015 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 2015 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.
