Abstract

Motor induksi merupakan salah satu motor listrik yang luas penggunaannya. Dalam kondisi tertentu motor induksi tak jarang mengalami kerusakan yang disebabkan oleh beban berlebih, hubung singkat di dalam kumparan, maupun kondisi lingkungan yang membuat motor induksi bekerja diluar batas kemampuannya. Salah satu akibat dari kerusakan pada motor induksi adalah kondisi kumparan yang tidak memungkinkan untuk digunakan lagi sehingga harus dilakukan rewinding. Setiap tipe belitan stator motor induksi akan menghasilkan distribusi magnetomotive force (MMF) pada celah udara yang berbeda. MMF yang dihasilkan terdiri dari komponen fundamental dan komponen harmonisanya. Jumlah komponen harmonisa pada distribusi MMF celah udara menimbulkan torsi parasit yang akan berpengaruh pada unjuk kerja motor induksi. Pada penelitian ini akan dilakukan penelitian perbandingan bentuk distribusi MMF celah udara terhadap dua tipe belitan yang berbeda yakni terbagi-screw (Motor A) dan terpusat-terditribusi (Motor B) pada motor induksi 1 fasa dengan kapasitas 1 kW 1000 rpm. Dari analisis harmonisa dan berbeban Motor A memiliki komponen harmonisa lebih tinggi dibanding Motor B sehingga Motor B memiliki peforma yang baik dalam hal torsi sebesar 4,608 Nm dibanding Motor A sebesar 3,37 Nm.

Abstract

Single phase induction motors are one of the most frequently used types of motors because of their economical, sturdy, simple and easy maintenance advantages. One application is for electric vehicles. When single phase induction motors are applied to electric vehicles there are problems related to torque regulation based on vehicle operating conditions where when operating on light road conditions the torque produced by the motor remains high. In this research, a single-phase induction motor was made to have the same proportion of torque produced by the main coil and auxiliary coil or a 1kW 1000 rpm symmetrical two-phase induction motor. The type of winding applied to the stator is divided screws with the main and auxiliary coils each occupying 18 stator slots, 45 conductors per slots,, with a conductor diameter of 1.2 mm. As a phase shifter at start and operation so that they differ by 90°, a capacitance of 505.51 µF is used. As a result of the winding modification, the induction motor parameter values ​​for each stator winding are the same. So the starting torque of the main and auxiliary coils is 3.89 Nm and 3.88 Nm respectively and the nominal torque produced by the main and auxiliary coils is 4.28 Nm and 4.29 Nm respectively.

Abstract

Load imbalance in electrical distribution transformers can lead to significant power losses and decreased efficiency in electrical distribution systems. This study focuses on the load imbalance problem at the Unicora feeder of PT PLN (Persero) ULP Singosari, which hinders optimal operational efficiency. The purpose of this research is to evaluate the extent of load imbalance, its impact on power losses, and the effectiveness of load balancing interventions in mitigating these losses. The methodology includes phase load measurements from February to September 2021, analysis of load imbalance, and power loss simulations using ETAP 12.6.0 software. The study's important findings indicate that the average load imbalance decreased from 34% to 21% after implementing load balancing interventions. Concurrently, power losses in the neutral conductor were reduced from 106.3 kW to 78.0 kW. ETAP simulations revealed a total power loss of 773.5 kW in the Unicora feeder, underscoring the significant impact of load imbalance on system efficiency. The implications of this research are crucial for operational practices at PT PLN (Persero) ULP Singosari. The findings demonstrate that effective load balancing can significantly enhance distribution efficiency, reduce operational costs, and improve the reliability of electricity provision.

Abstract

Transformers are considered important equipment in the power distribution system. Determining the state of the distribution network loading curve a network model to analyze the impact of the rooftop PV system penetration level. The assumption of penetration is 10% - 100% and based on the amount of transformer power according to the nameplate, which is 160 kVA. The transformer that used is GTT BB1215, which is one of the distribution transformers in the PT PLN (Persero) UP3 South Surabaya. The loading curve modeling uses DIgSILENT PowerFactory 2021 software with the Quasi-Dynamic Simulation feature. Based on the average loading curve of GTT BB1215 for 14 days, there is a fluctuation, starting at 00.00 a.m - 06.00 a.m the load will decrease, the load will increase again at 06.00 a.m – 07.00 p.m, and the peak load at 06.00 p.m - 07.00 p.m with a current of 140 A (96 kW) or 60% of the transformer capacity load. The lowest load occurs at 06.00 a.m with a current of 94 A (65 kW) or 40% of the transformer capacity load. At a penetration level of 10% - 40%, the transformer load decreases significantly. However, when the penetration level exceeds 40%, there is a reverse power flow from the rooftop PV system to the transformer. This condition make the current to continue flowing even though the load on the transformer has reached 0, because the current represents the power flow from the rooftop PV system to the network, not from the customer load.

Abstract

Kecamatan Jabung memiliki penduduk dengan beragam profesi, di mana 19% bekerja sebagai petani dan peternak, berdasarkan data survei penduduk Kabupaten Malang tahun 2021. Komoditas utama peternakan di Jabung adalah sapi perah, yang mampu menghasilkan 10.000 liter susu per hari. Selain sapi perah, beberapa warga juga memelihara kambing perah. Susu kambing dikumpulkan setiap pagi dan sore, lalu disalurkan ke pabrik pengolahan melalui stasiun pengumpul yang dikelola oleh CV Amanah, yang juga bertindak sebagai distributor. Namun, warga Jabung masih menggunakan cara manual dalam memerah susu kambing, yang kadang menyebabkan kualitas susu yang dikirim ke stasiun pengumpul tidak memenuhi standar, sehingga nilai ekonominya menurun. Untuk mengatasi masalah ini, dilakukan pemberdayaan masyarakat melalui penyediaan peralatan perah bertenaga listrik portabel bagi peternak kecil di Desa Kemantren, Kecamatan Jabung. Alat ini menggunakan baterai dengan kapasitas 7 liter/jam, yang diharapkan dapat mempermudah pekerjaan memerah susu pada peternak kecil dengan aset 1-3 ekor kambing atau sapi. Pemberdayaan ini bertujuan untuk meningkatkan kesejahteraan masyarakat dan menjaga kualitas susu yang dihasilkan.
