Analisis Probabilitas Kecepatan Angin untuk Pesisir Cilacap dengan Menerapkan Distribusi Weibull dan Rayleigh
Abstract: Wind characteristics
especially the event probability have been more studied in the relation to wind
energy availability in an area. Nevertheless, in the relation to coastal
structure, it is still rare to be unveiled in a paper particulary in Indonesia.
In this article, therefore, it is studied probability distribution commonly
used to wind energy analysis i.e. Weibull and Rayleigh distribution. The
distribution is applied to analyze wind data in Cilacap Coast. Wind data
analyzed is from Board of Meteorology, Climatology and Geophysics, Cilacap
branch, along two years (2009 – 2011). Mean, varians and standard deviation are
founded to calculate shape factor (k) and scale factor (c) which must be
available to arrange distribution function of Weibull and Rayleigh. In the
region, it gains a result that wind speed probabilities follow Weibull and
Rayleigh function fairly. Shape parameter value has been gotten k = 3,26, while
scale parameter has been gotten respectively c = 3,64 for Weibull and Cr = 2,44
for Rayleigh. Value of k ≥ 3 indicates the region has regular and steady wind.
Besides, mean speed of wind is 3,3 m/s.
