Abstract
Dewasa ini, Tuned Mass Damper (TMD) merupakan salah satu alat kontrol getaran yang paling mudah dan paling terpercaya untuk mengurangi efek getar yang terjadi pada struktur pendukung turbin. Massa sistem yang terdistribusi secara seragam lebih efektif dalam mengurangi puncak faktor pembesaran dinamis dan massa sistem yang terdistribusi secara linear lebih kuat selama tidak terpasang sesuai.
Pada umumnya penambahan TMD diterapkan pada sejumlah gedung tinggi bertingkat. Namun pada tugas akhir ini dilakukan simulasi pada sistem turbin angin tipe WES 80. TMD dirancang dengan volume sebesar 0.6 x 0.4 x 0.4 m. Pemodelan dinamis sistem dengan penambahan TMD disimulasikan pada software Simulink MATLAB. Ada 3 variasi Kecepatan kerja awal angin yang digunakan (Vo) adalah 5 m/s, 12 m/s, dan 18 m/s. Massa peredam (Ma) sebesar 5%, 7%, dan 9% dari massa utama (menara dan nacelle) disimulasikan dengan input sinusoidal yang mewakili rata-rata beban angin, dan input bump modified mewakili perubahan kecepatan angin mendadak tinggi.
Dari hasil simulasi didapatkan TMD dengan Massa Peredam 7% dan 9%, mampu mereduksi getaran paling baik di seluruh kecepatan angin. Sistem turbin angin TMD dengan input bump modified memiliki respon transient lebih lama daripada sistem tanpa TMD. Sistem TMD tidak efektif bekerja untuk mereduksi getaran saat ada perubahan kecepatan angin mendadak tinggi sesaat.
==========================================================
Currently, Tuned Mass Damper (TMD) is one of the easiest and most reliable vibration control devices to reduce the vibration effects that occur in wind turbine support structures. The mass of uniformly distributed systems is more effective in reducing the peak of dynamic enlargement factors and the linearly distributed mass of the system more robust as long as it is not installed accordingly.
In general, the addition of TMD is applied to a number of high rise buildings. However, in this final project simulation on wind turbine system type WES 80. TMD has been designed with the volume of 0.6 x 0.4 x 0.4 m. Dynamic modeling of systems with the addition of TMD is simulated on MATLAB Simulink software. There are 3 variations of the working speed of the wind used (Vo) is 5 m / s, 12 m / s, and 18 m / s. Mass dampers (Ma) of 5%, 7%, and 9% of the main mass (tower and nacelle) are simulated with sinusoidal inputs representing the average wind load, and the modified bump input represents a sudden high wind speed change.
From the simulation results obtained TMD with Mask Damper 7% and 9%, able to reduce the best vibrations in all variations of wind speed. The TMD wind turbine system with modified bump input has a longer transient response than a system without TMD. The TMD system does not work effectively to reduce vibration when there is a sudden high speed change in the wind speed.
