Abstract

Peningkatan kebutuhan listrik setiap tahun, khususnya di pulau Jawa, mengharuskan pemerintah melalui PT. PLN (Persero) melakukan pengembangan kapasitas dan produksi energi listrik guna mengatasinya. Pada sistem kelistrikan Jawa-Bali ditambahkan generator baru di Grati. Generator tersebut berjumlah tiga unit, terdiri dari dua unit generator turbin gas berkapasitas 207 MVA dan satu unit generator turbin uap berkapasitas 248,75 MVA. Penambahan pembangkit baru tersebut mengharuskan dilakukannya analisis ulang terhadap kinerja sistem secara keseluruhan. Kajian ini menganalisis stabilitas transien dalam kondisi beban puncak dan beban dasar. Hasil simulasi stabilitas transien menggunakan software ETAP menunjukkan bahwa untuk kondisi beban puncak dan beban dasar, kasus lepasnya generator dan hubung singkat tiga fasa pada saluran transmisi selama 150 milidetik tidak menyebabkan sistem lepas sinkron. Pada kasus generator lepas, daya supply yang hilang hanya sebesar 4,71% dari kondisi beban puncak dan 6,69% dari beban dasar daya pembangkitan. Pada kasus gangguan hubung singkat tiga fasa pada saluran transmisi selama 150 milidetik pada kondisi beban puncak dan beban dasar, hasil respon sudut rotor, frekuensi dan tegangan menunjukkan sistem tetap stabil. Namun, pada kondisi beban puncak terjadi drop tegangan sampai 104,632 kV dan pada beban dasar terjadi drop tegangan sampai 114,479 kV. Waktu pemutusan kritis pada kondisi beban puncak lebih cepat jika dibandingkan dengan pada kondisi beban dasar.

Abstract

Micro hydro power plants (PLTMH) have the potential as an alternative source of electrical energy, especially in rural areas or remote areas that have abundant air potential. However, the PLTMH also has a problem, namely the electric power which produces a small connection with the distance of the generator is far from the point of load so that problems such as power lossand voltage drop arise so that it is necessary to do a power loss analysis to find out the condition of the power loss and voltage drop to increase the reliability of the system by This research was conducted at the Andungbiru Village PLTMH, Tiris District, Probolinggo. With power loss analysis using the Newton Raphson method, using Matlab software to obtain a large channelpower loss value and efficiency using the Newton Raphson method with an R phase of 918.21 Watt with an efficiency of 61.54%. The S phase is 1098.40 Watt with an efficiency of 55.76%. Phase T is 1073.5 Watt, with an efficiency of 57.14%. Then do a load simulation using the Etap software for the Probolinggo PLTMH, get the value of the power loss and efficiency of the R, S, T phases before being installed. The purchase is the R phase with a loss of 702.94 watts and an efficiency of 70.556%, for the S phase with a loss of 819.90 watts and an efficiency of 67.034%, for phase T with a power loss value of 756.98 and an efficiency of 69.78% after that we simulated adding bank purchases to the PLTMH and getting the most optimal bank placement at the end of the channel, namely for phase R on the bus 6 R with a power loss of 616.13 watts with an efficiency of 74.192%, then phase S is located on the 5S bus with a loss value of 748.08 Watts and an efficiency of 69.923%. Then the T phase is located on the 5 T bus with a power loss of 680.27 Watt and an efficiency of 72.848%. Keywords: PLTMH, Newton-Raphson, efficiency, loss, power

Abstract

Distance between power plant and load, growth in industrial sector, and population growth are several reason for the increase in voltage drop on a distribution electrical system. In some cases, voltage drop that happened sometimes can lead to the voltage drop beyond the specific limit which is 10%. One of the solutions we can use to prevent this is Optimum Capacitor Placement(OCP). OCP is a method which using the capacitor bank to supply the reactive power for the compensate for reactive power due to the load. In this research, the problem refers to Sentral Feeder of GI Rangkas which have 35 Distribution Transformer. Power flow analysis and OCP in this research will be done with the help of ETAP 12.6. in this research the optimation will be performed with maximum load. The result from Power flow analysis shows that at the maximum load, there is 10 buses which the voltage drop beyond the limit, hence OCP will be needed so the voltage drop can rise again beyond the limit of 10%. The OCP on ETAP 12.6. generates 4 bus candidates for the placement of capacitor bank, after 3 400 kVAR capacitor banks installed on STO bus, voltage drops reduces until the point where no buses on this system have voltage drop passing the limit. Power losses on the system also got reduced from 285 kW to 211 kW and 83 kVAR to 62 kVAR. Keywords—Voltage drop, Power flow analysis, Optimum Capacitor Placement(OCP), ETAP 12.6

Abstract

Bus-bus beban selama ini hanya dianggap sebagai beban saja tanpa dianggap sebagai elemen jaringan. Menganggap beban sebagai elemen jaringan berarti bus-bus beban dapat dimasukkan ke dalam admitansi atau impedansi jaringan. Hasil iterasi untuk mencapai konvergen, analisis aliran daya dengan menganggap beban sebagai elemen jaringan (170 iterasi) lebih banyak dibandingkan analisis daya standar (168 iterasi). Ini membuktikan analisis daya standar pada sistem jaringan IEEE 14 Bus mempunyai tingkat iterasi yang lebih baik. Kecepatan iterasi untuk mencapai konvergensi berbanding lurus dengan tingkat iterasinya, semakin sedikit tingkat iterasinya maka semakin cepat untuk mencapai konvergen. Total rugi-rugi daya, pada pada kedua metode adalah sebesar 0.4315 + 0.6764i (pu) dengan nilai konvergensi sebesar 0.00001.
