Abstract

Motor induksi satu fasa banyak digunakan karena konstruksinya yang kokoh, relatif sederhana, mudah dalam perawatan, dan harga yang murah. Konfigurasi atau tipe belitan stator berpengaruh terhadap nilai impedansi motor. Pada penelitian ini dibuat dua tipe belitan atau  konfigurasi yang berbeda. Tipe belitan yang diteliti adalah terbagi-skrup (Mesin A) dan terpusat terdistribusi (Mesin B). Tujuan dari penelitian adalah untuk mendapatkan tipe belitan yang menghasilkan unjuk kerja motor yang baik. Langkah yang dilakukan adalah mendapatkan beda sudut fasa arus antara kumparan utama dan bantu yang ideal dengan kumparan yang simetri. Beda sudut fasa arus yang ideal adalah sebsesar 90°. Kumparan yang simetri yaitu jumlah kumparan utama dan bantu sama banyaknya. Hal tersebut dapat menghasilkan torsi yang optimum dan arus yang setimbang. Motor yang dirancang dianalisis menggunakan metode elemen berhingga dengan bantuan perangkat lunak FEMM 4.2. Simulasi dilakukan pada keadaan nominal. Kerapatan fluks rata-rata celah udara (Bav) yang didapat dari simulasi digunakan untuk menghitung kapasitas motor. Pada penelitian ini juga dilakukan analisis daya dan torsi dengan perhitungan parameter dan pengujian berbeban. Hasil simulasi dan pengujian menunjukkan Mesin B memiliki torsi yang lebih tinggi dibanding Mesin A. Faktor yang berpengaruh adalah jumlah komponen harmonisa pada gaya gerak magnet (Magnetomotive force-MMF) dan distribusi medan yang dihasilkan kumparan stator.

Abstract

Potential renewable energy source in Indonesia today for hydropower around 75.67 GW and newly used about 4.2 GW. Utilization of energy in the present has been directed to the use of renewable energy in nature. Based on that idea, innovation and testing are done by designing Floating hydro power plant (FHPP) FHPP is designed by utilizing irrigation water sources to meet small-scale power consumption, especially for household consumers with 450-500 watts of power. FHPP design process is done by first analyzing the related data such as planned power and other related variables. After the size and dimensions of FHPP is known the next stage is to make the model FHPP using Ansys 18.00 software, the goal to find the optimal design of FHPP which can generate electrical power between 300-450 watts. While the components of FHPP itself consists of pontoon, waterwheel, permanent magnet generator (GMP) as an electricity generator, voltage rectifier, voltage stabilizer and battery that serves to store voltage generated by GMP. After FHPP design is completed the next stage is the mechanical testing of FHPP by using an electric motor as a substitute for water flow and experimental testing conducted by utilizing irrigation water flow. From this test obtained voltage generated by gmp is direct current (DC) with a maximum power of 480 Watt, 600 gpm rpm rotation with maximum torque of gmp of 0.42 kgm. The resulting voltage is converted to alternating current (AC) by using a converter so that it can be used to meet household electrical needs.

Abstract

Doubly-fed induction generators connected to the power grid are widely used in wind farms as a part of the power system. The wind turbines are in general susceptible to grid disturbance in a form of transient faults which often result in voltage dips. The DFIGs are connected to the grid via conductors whose operating mechanism depends on the grid voltage through an auxiliary transformer. This paper discusses the effects of grid voltage dips on the doubly-fed induction generator and its main contactor. The study focuses on the modeling and simulation of a doubly-fed induction generator and a wind turbine connected to the grid through ac contactors. The model is subjected to various symmetrical voltage dips and their effects on the grid contact mechanism of the DFIG generator during these transient faults are explored to find out the minimum voltage dip which still keeps the contactor engaged. The impacts of the grid transients on the performance behaviour of the doubly-fed induction generator are also observed.
