Abstract
Kegagalan turbin angin seringkali memberikan dampak yang buruk bagi industri tenaga angin. Hal ini dikarenakan biaya perawatan saat turbin angin mengalami kegagalan jauh lebih besar dibanding biaya perawatan saat turbin angin belum mengalami kegagalan. Kegagalan pada turbin angin ini dapat diminimalisir dengan melakukan monitoring keandalan turbin angin real-time. Pada makalah ini dilakukan perancangan monitoring keandalan real-time pada turbin angin berdasarkan estimasi kesalahan. Langkah-langkah yang perlu dilakukan adalah studi spesifikasi turbin angin, pemodelan turbin angin, perancangan dan uji algoritma observer serta algoritma monitoring keandalan real-time. Uji observer dan uji monitoring keandalan dilakukan dengan terlebih dahulu memberikan kesalahan sensitivitas pada sensor, sebesar 5%; 7,5%; 10%; dan 12,5%. Berdasarkan hasil uji telah dilakukan, pada kesalahan sensitivitas diberikan pada sensor kecepatan sebesar 5%, 7.5%, 10% dan 12.5%, masing-masing mampu mengestimasi kesalahan yang telah disimulasikan pada detik ke-1300; 1350; 1400; dan 1450. Berdasarkan hasil uji monitoring keandalan real-time, didapatkan bahwa pada kesalahan sensitivitas sensor sebesar 5%; 7,5%; 10%; dan 12,5%, masing-masing nilai keandalan mulai mengalami penurunan pada detik ke-532,6; 532,8; 533,2; dan 533,7.

Failure of wind turbines often has a devastating impact on the wind power industry. This is because the cost of maintenance when the wind turbine failure is much greater than the cost of maintenance when wind turbines have not failed. Failure of this wind turbine can be minimized by monitoring the reliability of real-time wind turbines. In this paper the design of real-time reliability monitoring on wind turbines is based on error estimation. The steps that need to be done are wind turbine specification studies, wind turbine modeling, design and observer test algorithm and real-time reliability monitoring algorithm. The observer test and reliability test are performed by first giving sensitivity error to the sensor, at 5%; 7.5%; 10%; and 12.5%. Based on the test results, the sensitivity error was given at 5%, 7.5%, 10% and 12.5% velocity sensors, each capable of estimating simulated errors at 1300 seconds; 1350; 1400; and 1450. Based on real-time reliability reliability test result, it was found that at sensor sensitivity error of 5%; 7.5%; 10%; and 12.5%, each reliability value starts to decrease at 532.6 seconds; 532.8; 533.2; and 533.7.
