Abstract

Tegangan yang tidak stabil dalam suatu sistem tenaga listrik dapat menyebabkan terjadinya gangguan dalam pelayanan. Untuk itu diperlukan perencanaan sistem tenaga listrik yang mempertimbangkan stabilitas tegangan. Salah satu metode yang dapat digunakan untuk menganalisa tegangan adalah dengan menggunakan nose curve (kurva P-V). Kurva ini dapat menjelaskan hubungan antara tegangan dan daya aktif pada suatu bus. Perubahan beban akan mempengaruhi nilai tegangan, sehingga dapat diperoleh nilai tegangan kritis untuk pembebanan maksimum. Untuk meningkatkan stabilitas tegangan ditempatkan beberapa unit Distributed Generation (DG) pada bus distribusi atau bus beban.

Abstract

This paper presents a techno-economic analysis and environment assessment of hybrid photovoltaic (PV), wind turbine (WT), and diesel genset (DG) with pumped hydro storage (PHS) for a rural microgrid system. The analysis is carried out for a case study with Mentawai community load demand of 165.44 kWh/day at a peak load of 20.46 kW. The Homer simulation results show that there are eight feasible configurations, which the optimal hybrid system configuration to supply community load is the configuration with PV/DG/PHS. An optimal system has been achieved for the lowest NPC of Indonesian rupiah (IDR) 3,00 B consist of 15 kWp PV modules, 1 unit of PHS and a solar inverter with a size 25 kW. The net present cost and payback period are in accordance with criteria for the economic feasibility analysis method of a project. However, the cost of energy is greater than the electrical utility tariff, but this value can be considered for applications in the remote island area. Therefore, the project still feasible to be implemented. Since the renewable fraction of the system is increased hence this proposed system will have the lowest carbon emission.

Abstract

Hand gesture recognition is a topic that is still investigated by many scientists for numerous useful aspects. This research investigated hand gestures for sign language number zero to nine. The hand gesture recognition was based on finger direction patterns. The finger directions were detected by a Leap Motion Controller. Finger direction pattern modeling was based on two methods: threshold and artificial neural network. Threshold model 1 contained 15 rules based on the range of finger directions on each axis. Threshold model 2 was developed from model 1 based on the behavior of finger movements when the subject performed hand gestures. The ANN model of the system was designed with four neurons at the output layer, 15 neurons at the input layer, seven neurons at the first hidden layer and 5 neurons at the second hidden layer. The artificial neural network used the logsig as the activation function. The result shows that the first threshold model has the lowest accuracy because the rule is too complicated and rigid. The threshold model 2 can improve the threshold model, but it still needs development to reach better accuracy. The ANN model gave the best result among the developed model with 98% accuracy. LMC produces useful biometric data for hand gesture recognition.

Abstract

The 20 kV feeder outages typically caused by short circuit fault. If the setting of over current relay (OCR) in the incoming or outgoing feeder unfavorable, can cause a total blackout. One of the efforts can be done is to evaluate the settings of 20 kV feeder protection relays in distribution substations Pauh Limo, to be well coordinated with each other and expected if an interruption in one of the 20 kV feeders it will not bring interrupt on the other feeders.Based on the short circuit current analysis on each feeder, where the largest short circuit fault current for three-phase fault at feeder Tingga Koto, the fault location 1%, which amounted to 7326.99 Ampere. This is because the line to Koto Tingga shortest compared to other feeders, around 9 km and load current = 230 Ampere. The OCR working time at the feeders id: Kuranji = 0.3 s Koto Tingga = 0.298 s, Teluk Bayur-2 = 0.292 s, Teluk Bayur-1 = 0.3 s, BLKI = 0.3 s, Kandis = 0.3 s and feeder UNAND = 0, 3 s. The relay working time for incoming side is 0.7 seconds. This relay setting can be used as a reference of evaluation and  resetting of  OCR.Keywords : Short circuit fault, Over current relay,  Relay setting.ABSTRAK—Pada penyulang 20 kV biasanya pemadaman disebabkan oleh gangguan hubung singkat. Jika penyetelan over current relay (OCR) di sisi incoming atau di outgoing kurang baik, dapat menyebabkan pemadaman total (black out). Salah satu upaya yang dilakukan adalah dengan mengevaluasi setting relai proteksi pada penyulang distribusi 20 kV gardu induk Pauh Limo, sehingga saling terkoordinasi dengan baik dan diharapkan jika terjadi gangguan pada salah satu penyulang 20 kV maka tidak akan membawa black out pada penyulang yang lain.Berdasarkan analisa arus hubung singkat disetiap penyulang, dimana arus gangguan hubung singkat 3 fasa terbesar yaitu pada penyulang Koto Tingga, dengan lokasi gangguan 1 %, yaitu sebesar 7326,99 Ampere. Hal ini dikarenakan saluran Koto Tingga terpendek dibandingkan dengan penyulang lain, yaitu = 9 km dan arus beban = 230 Amper. Waktu kerja relai pada penyulang (detik) : Kuranji = 0,3, Koto Tingga = 0,298, Teluk Bayur-2 = 0,292, Teluk Bayur-1 = 3, BLKI = 0,3, Kandis = 0,3 dan penyulang UNAND = 0,3. Pada sisi incoming waktu kerja relai adalah 0,7 detik. Setting relai ini dapat digunakan sebagai referensi dalam evaluasi dan setting ulang OCR.Kata Kunci : Gangguan hubung singkat, Relai arus lebih, setting relai..

Abstract

This  paper  presents the  assessment  of  fast  decoupled load flow computation using three linear system solver scheme. The full matrix version of the  fast  decoupled  load flow  based on XB  methods used in this study.  The numerical investigations are carried out  on  the  small and large test systems.  The execution time of small system such as IEEE 14, 30, and 57 are very fast, therefore the computation time can not be compared  for these cases.  Another cases IEEE 118, 300 and TNB 664 produced significant execution speedup. The superLU factorization sparse matrix solver has best performance and speedup of load flow solution as well as in contigency analysis. The invers full matrix solver can solved only for IEEE 118 bus test system in 3.715 second and for another cases take too long time. However for superLU factorization linear solver can solved all of test system in 7.832 second for a largest of test system. Therefore the superLU factorization linear solver can be a viable alternative applied in contingency analysis.Keywords : Fast Decoupled Load Flow, Contigency Analysis, and Linear System Solver
