Pengujian kinerja turbin selain diuji di lapangan dapat pula dilakukan dengan menggunakan fasilitas terowongan angin. Tujuan penelitian ini adalah mengetahui sebuah sistem akuisisi data yang handal yang diperlukan dalam pengujian kinerja turbin angin ini.

Besides on-site test, the turbine performance can also be tested by using wind tunnel facilities.The purpose of this study was to determine a reliable data acquisition system that is required in this wind turbine performance testing. The concept of a user friendly, real-time, distributed-integrated and embedded hardware-based data acquisition system is applied. This concept leads to a simple and practical data acquisition process without leaving main rules of power performance testing according to IEC 61400-12-1 standard.</p><strong><strong></strong></strong><p>Keywords<span style="font-family: Arial,Arial; font-size: xx-small;">: data acquisition, wind tunnel, wind turbine, power performance. </span></p>
