Abstract

Power System Stabilizers (PSS) are added to excitation systems, in order to enhance the damping of electric power system during low frequency oscillations. For large scale power systems comprising of many interconnected machines, the PSS parameter tuning is a complex exercise due to the presence of several poorly damped modes of oscillation. The problem is further being complicated by continuous variation in power system operating conditions. In the simultaneous tuning approach, exhaustive computational tools are required to obtain optim um parameter settings for the PSS, while in the case of sequential tuning, although the computational load is fewer, evaluating the tuning sequence is an additional requirement. There is a further problem of eigenvalue drift. This research proposes the PSS model based on IEEE Standard 421.5 PSS 4B for designing robust power system stabilizers for a multi machine system. Simulations were carried out using several fault tests at transmission line on a Two-Area Multimachine Power System. As a reference the PSS model, Delta w PSS and Delta Pa PSS has been used for comparison with the PSS under consideration. The result shows that power transfer response using the model is more robust than Delta w PSS and Delta Pa PSS, especially for three phase faults and phase to ground faults.

Abstract

Sumber energi terbarukan yang sangat potensial adalah energi mikrohidro dan surya. Dalam aplikasinya, diperlukan suatu pembangkit listrik berukuran kecil dengan beban listrik yang sesuai yang dapat digunakan secara fleksibel. Dalam penelitian ini dibahas performa pembangkit listrik hibrid tenaga surya dan mikrohidro portable. Pembangkit listrik hybrid tersebut dirancang dengan kapasitas maksimum 1100 watt. Pembangkit listrik yang dirancang adalah bersifat portable, sehingga dapat dibawa dan dipindahkan dengan mudah sesuai lokasi yang sesuai. Lokasi yang sesuai untuk operasional pembangkit listrik ini adalah saluran irigasi, sungai kecil, atau selokan dengan area terbuka. Hal ini dimaksudkan agar pembangkit listrik ini menghasilkan daya listrik yang optimal, karena selain mendapatkan aliran air untuk menggerakkan mikrohidro juga mendapatkan paparan sinar matahari yang cukup. Ujicoba pembangkit listrik ini telah dilakukan untuk uji tanpa beban dan menghasilkan keluaran tegangan yang memadai. Pengujian telah dilakukan untuk pulley turbin mikrohidro berukuran 45 mm dan 100 mm. Hasil pengujian menunjukkan bahwa pulley turbin mikrohidro berukuran 45 mm menghasilkan daya listrik yang lebih tinggi dibanding pulley 100 mm.
