Abstract

ABSTRACT PT PJB UBJ O&M Rembang PLTU is one of the Java Bali steam power plants, which the output that produced by the Rembang PLTU generator is 315 MW. Generator is the core equipment of system which has different of operating characteristics and protection systems. Disturbances in generators include damage to generators or auxiliary devices, single-phase short circuit current, three-phase short-circuit current and imperfect electrical contacts. To avoid such interferences, a protection system is needed, one of which uses differential relay. This device works very fast and does not require time delay by detecting the difference in the current entering the stator coil, if the current accross on the stator coil is different then the differential relay will work. The purpose of this study is to analyze the differential relay settings on generators installed at PT PJB UBJ O&M Rembang PLTU which affect the reliability of the generator. The method used in this study is a quantitative method, where in this method a research approach is widely demanded to use numbers from data collection, processing of data, and appearance of the results. The relay setting obtained from this study is 0.1804 A, which means it is still in good condition, so it can carry out its duties as a protection system.Keywords: Generator, Differential Relay, Short Circuit, Protection System ABSTRAK PT PJB UBJ O&M PLTU Rembang merupakan salah satu pembangkit listrik tenaga uap Jawa Bali, dimana output yang dihasilkan generator PLTU Rembang sebesar 315 MW. Generator merupakan peralatan utama dari sistem pembangkitan yang memiliki karakteristik pengoperasian dan sistem proteksi yang berbeda. Gangguan pada generator diantaranya kerusakan generator atau alat bantu generator, arus hubung singkat satu fasa, arus hubung singkat tiga fasa dan kontak-kontak listrik yang belum sempurna. Untuk menghindari gangguan tersebut diperlukannya sistem proteksi, salah satunya menggunakan rele differensial. Rele differensial ini bekerja dengan sangat cepat dan tidak memerlukan penundaan waktu (time delay) dengan cara mendeteksi perbedaan arus yang masuk melalui kumparan stator, apabila arusnya berbeda maka rele differensial akan bekerja. Tujuan penelitian ini adalah untuk menganalisis penyetelan rele differensial pada generator di PT PJB UBJ O&M PLTU Rembang yang berpengaruh terhadap keandalan pembangkit. Metode yang digunakan pada penelitian ini adalah metode kuantitatif, dimana dalam metode ini dilakukan pendekatan penelitian yang banyak dituntut menggunakan angka dari pengumpulan data, pengolahan terhadap data, serta penampilan hasilnya. Hasil yang didapat dari penelitian ini setelan rele differensialnya sebesar 0,1804 A, yang berarti masih dalam keadaan baik, sehingga dapat menjalankan tugasnya sebagai sistem proteksi.Kata kunci: Generator, Rele Differensial, Hubung Singkat, Sistem Proteksi

Abstract

In the operation of the electric power system, good quality service is needed. One of them is thevoltage value received by the customer does not get a voltage drop. Based on SPLN No.1: 1978, theservice voltage is a maximum of 5% and a minimum of 10% of the nominal voltage of the LowVoltage Network that is 220 Volt. One of the locations experiencing voltage drop problems is on theCentral Pakandangan Village, Sumenep. Based on an analysis do by the PT PLN UP3 PamekasanNetwork division, it turns out that the voltage drop that occurred on Central Pakandangan Villagecaused by the location. The location is to far from the KH 007 distribution substation, which is 643meters. Then, the area around the location also has a high burden due to the many standingresidential settlements. Therefore, it is necessary to break the load on the network. This method isdone by moving or transferring part of the load from the old network to the new network. Which isthe last 5 poles in this line. so the load supported by one line does not have voltage drop. The resultobtained after performing the load break is that the voltage on the receiving side rises to phase R200 Volt, phase S 212 Volt, and phase T 202 Volt. Where previously the value of the voltage on thereceiving side is phase R 189 Volt, phase S 206 Volt, and phase T 194 Volt.

Abstract

It is undeniable that the low value of the power factor can cause problems with the electrical load in the form of power consumed that does not match the installed power. A low power factor can cause power usage to be less than optimal and current increase so that it can result in increased heat losses in the cable. From the data, there are still many customers who have a power factor of 0.5 to 0.7 meaning they are below the standard, for this reason it is necessary to improve the power factor value by installing capacitors where it is necessary to calculate the capacitor’s capacity according to the installed power, so as to optimize the distribution of funds and reduce heat losses from the conductor so that the distribution condition is more stable. The diagram method is used, a diagram showing the kVAR value is needed before and after compensation. With the improvement of the power factor in accordance with the standard, a more optimal use of electric power is obtained. From the results of the calculations, the average capacity of the capacitor used for household customers with a power of 6600 VA is or 37.4 F.

Abstract

PLTS converts electromagnetic energy from sunlight into electrical energy. On-Grid PLTS Design at the Civil Service Police Office of Ende Regency generates 7 kWp of power, with 35 panels used, each with a capacity of 200 Wp. The triangular roof area is 44m2. The inverter used is 1 unit with a capacity of 4 kW. The purpose of this study is to reduce the use of conventional PLN energy to meet energy needs at the Civil Service Police Station, Ende Regency. This plan requires a cost of Rp. 130.935.000. From the average daily load requirement of 35302 W/h, this plan produces 34450 W/h to meet 97% of the needs of the Ende District Civil Service Police Station.

Abstract

This work study voltage correction using capacitor banks on PLN’s network distribution with medium voltage consumer of PT. Panca Agung Sejati. Voltage drop into PT. Panca Agung Sejati network in operation condition is 17.87 kV, it mean happened voltage drop in persentage of 10.65. That is not apropriate to the SPLN 72:1987 standard, that is+ 5%. While, voltage drop on the network of the company is still in the range of SPLN standard when it is not on operation by 19.67 kV (1.65%). Then, efforting to improve the voltage drop the PT. PLN (Persero) has installed capacitor banks on the network at PT. Panca Agung Sejati with a total capacity are 3 x 400 kVAR. This research simulates using ETAP 16.0 software to find out whether the capacitors are still effective for load growth in the next 10 years. Simulation result with the capacitors installed of 3 x 400 kVAR is 19.15 kV (4.25%) that is mean it has already in the range of SPLN standard. For load growth until year of 2030 will be needed five capacitors in capacity of 400 kVAR (5 x 400 kVAR) to correcting the occurred voltage drop.

Abstract

Substation is part of the electric power system that distributes electrical energy from the generator to the load. It is necessary to ensure safety and security guarantees for the installed equipment and humans at the substation. This research discusses the results of measuring grounding resistance on equipment in the switchyard with quantitative methods based on the results of measuring equipment grounding resistance, step voltage, touch voltage. The quantitative method is based on the quality of the equipment grounding resistance at the Angke Substation switchyard. The value of the equipment grounding resistance at the substation must be able to meet the IEEE Std standard 80 – 2000 that is < 1 ?. The smaller the grounding value obtained, the better of the grounding. Based on the results of this study, the value of the grounding resistance of the Angke Substation is 0,13 V. The value of the touch voltage is 651.55 V for humans weighing 70 kg and 481.4 V for humans weighing 50 kg. With the value of the permissible touch voltage is 626 V. The step voltage value is 2135.2 V for a human weighing 70 kg, and 1577.6 V for a human weighing 50 kg. With a permissible step voltage value of 2216 V.
