Abstract

One of the operating disruptions that occur in the synchronous generator is the loss of excitation. Where this interference will cause the generated reactive power generator is reduced even lost so that the synchronous generator must absorb the reactive power of the system. If this condition occurs continuously can cause damage to the stator coil, will occur worsening insulation and the stator end iron so as to cause short circuit, or interruption of soil relations in the future. So to anticipate the impact of such disturbances required a protection system. The protection system used in PLTGU Muara Tawar GT unit 1.3 is a minimum reactance relay. This jurnal discusses how to determine the value of loss excitation protection setting using minimum reactance relay and offset relay mho so that synchronous generator can work optimally. From the research calculation the minimum reactance relay usage will work on XA-setting value zone (-2.55 p.u) with 0.5 seconds delay time, XB-setting (offset) of -0.1156 p.u with 0.5 seconds delay time. As for offset relay mho will work on zone 1 and zone 2 for offset value of -0.109 p.u with delay time 0.1 second. As for zone 1 for the base impedance ( ) of -1.0 p.u with a delay time of 0.1 seconds and zone 2 synchronous reactance value ( of 2.423 p.u with a delay time of 0.5 seconds. From those results it is considered sufficient to detect the loss of excitation in the synchronous generator.

Abstract

A good electric power system must have a voltage value that does not exceed the tolerance limit and small power losses. The tolerable limit for a voltage value (+ 5%; - 10%) of its nominal value. A constant voltage value will optimize the performance of the electrical equipment used by the consumer. While the small power losses will keep the power supply in accordance with the needs of consumers, and can reduce financial losses that occur during the transmission and distribution process. In this thesis will be a study to improve the quality of stress on the distribution network by reconfiguring the network. The process of repair is done on medium voltage network by opening or closing Fuse Cut Out, Load Break Switch, Disconnecting Switch, adding substation insertion, and change the position of Process Tap Changer to provide the most optimum repair value. Improved voltage on this thesis is simulated using ETAP 12.6.0 software. From the simulation results will be obtained the most optimal voltage improvement is in the case study 1 on the most bus end of the Bus GRA 706 with a voltage of 16.12 kV, case study 2 voltage rose to 19.66 kV and case study 3 voltage to 19,661 kV.

Abstract

The power amplifier circuit is a circuit used to amplify or magnify input signals. The use of a transistor as an amplifier is that the current on the base is used to control the larger current given to the collector through the transistor. The small current change on the controlling base is what is called a large change in the current flowing from the collector to the emitter. The advantages of the amplifier transistors can not only amplify the signal, but these transistors can also be used as current amplifiers, voltage amplifiers and power amplifiers.

Abstract

The glycol regeneration process is an integrated part of the glycol dehydration unit (GDU) system. Each plant has a customized configuration to the needs of the process, for the case in this onshore field because the gas produced from the well is good enough with a fairly low water content, then does not use Glycol Contactor. Instead used low temperature separator and glycol generation unit. DCS DeltaV is used to operate, documentation and optimization of gas processes. By using oscillation method and closed loop system obtained PID tuning result with parameter P = 387, I = 57 and D = 53. The response of the control system is conditioned overshoot from its setpoint to accelerate the rise of the temperature plant. When the temperature of glycol regeneration is at 2620 F, the alarm will light Hi limit and Hi Hi limit at 2900 F, while at 2450F the alarm will light low limit and Low Low limit at temperature 00 F.

Abstract

Forecasting. Plans, power plants ,. Electricity needs are increasingly changing daily, so the State Electricity Company (PLN) as a provider of energy must be able to predict daily electricity needs. Short-term forecasting is the prediction of electricity demand for a certain period of time ranging from a few minutes to a week ahead. in shortterm electrical forecasting much of the literature describes the techniques and methods applied in forecasting, Autoregresive Integrated Moving Average (ARIMA), linear regression, and artificial intelligence such as Artificial Neural Networks and fuzzy logic. Short-term forecasting will be done by the authors using time series data that is the data of the use of electric power daily (electrical load) and ARIMA as a method of forecasting. ARIMA method or often called Box-Jenkins technique to find this method is suitable to predict variable costs quickly, simply, and cheaply because it only requires data variables to be predicted. ARIMA can only be used for short-term forecasting. ARIMA is a special linear test, in the form of forecasting this model is completely independent variable variables because this model uses the current model and past values of the dependent variable to produce an accurate short-term forecast.

Abstract

Meningkatnya penggunaan beban non-linier dalam instalasi kelistrikan mengakibatkan masalah distorsi harmonik dalam sistem kelistrikan industrial dan komersial.Beban non-linier yang banyak digunakan dalam operasi minyak dan gas bumi adalah variable speed drive (VSD) dan uninterruptible power supply (UPS). PT Medco E&P Indonesia memberdayakan Electrical Submersible Pump (ESP) sebagai metode produksi minyak bumi yang diterapkan di lapangan produksi Kaji Semoga. Instalasi ESP dilengkapi dengan VSD sebagai pendukung asut dan pengendali kecepatan motor penggerak ESP demi mencapai besaran produksi minyak bumi. Operasi VSD membangkitkan gangguan harmonik yang dapat mengganggu sistem daya listrik seperti panas berlebih dari peralatan listrik, kegagalan prematur pada peralatan berputar dan pembatas arus yang gagal kerja. Pada umumnya untuk mengendalikan masalah ini, harmonic filter dipasang untuk mengkompensasi distorsi harmonik. Instalasi harmonic filter berkontribusi pada biaya pemeliharan kehandalan sistem daya listrik di lapangan produksi Kaji Semoga. Makalah ini menjabarkan metode-metode alternatif untuk mengendalikan distorsi harmonik dalam sistem distribusi daya lsitrik termasuk pemasangan harmonic filter. Metode untuk mengendalikan distorsi harmoniktersebut termasuk penggunaan trafo phase-shifting. Metode lain untuk menanggulangi distorsi harmonik adalah merancang ukuran konduktor selain sebagai proteksi arus beban-lebih juga bisa menerima pengaruhharmonic pada arus beban. Metode-metode alternatif ini bisa mengurangi biaya dari usaha menghilangkan distorsi harmonik secara signifikan.
