Abstract

The power transmission system is essential for the power scheme to transfer the energy from generators to consumers. The short circuit problem repeatedly occurs in the transmission system, and the main problem is to separate the sources from users. This research has applied two hybrid techniques to predict fault location. The first hybrid technique has involved the Discrete Wavelet Transformation (DWT) and Adaptive Neuro-Fuzzy Inference System (ANFIS), while the second hybrid technique is for DWT grouping and Support Vector Machine (SVM). These hybrid techniques are intended to estimate the fault location of each fault category in a transmission system. The DWT was applied to both D8 and D9 level at the 50 kHz sample frequency. The root mean square (RMS) values of the D8 and D9 coefficients were used for training using ANFIS and SVM techniques. After that, ANFIS and SVM were utilised to detect faults in the phase and ground lines. Several types of fault have been simulated, i.e. fault location, fault resistance, and original point of view. The RMS results from the two hybrid techniques were compared to find the best results. The tests of error estimation were performed for the three bus systems. The comparison of error estimation of the two methods shows that both hybrid techniques can be applied to predict fault locations.

Abstract

PT RAPP is one of the companies that uses a three-phase induction motor in production where the motor is used as a pump, pulp dryer, or conveyor. Some districts in PT RAPP have used VSDs as controllers for three-phase induction motors, but some are still using the DOL system. This study aims to compare the energy use of a three-phase induction motor when it is connected to Direct On-Line (DOL) and when it is controlled by a Variable Speed Drive (VSD). This study also aims to analyze from an economic aspect, namely the total energy tariff per year and the calculation of the Pay Back Period (PBP) or the refund period. This research was conducted by collecting motor work data for a month. The research was conducted by observing the research subject, then collecting data on motor performance. The research data were taken from two districts, namely Fiberline 1 and Fiberline 2, the data that has been obtained will be calculated. There are 3 calculations in this research, namely calculation of total electrical energy, calculation of electricity rates and calculation of PBP. The results of this calculation will produce a large amount of electric energy when a three-phase induction motor is connected to the DOL and when VSD is controlled, savings in electricity rates when using a VSD and a period of return on investment in VSD installation. The results of data analysis on Fiberline 1 show the amount of energy saved when the motor uses a VSD of 802847.665 kWh with a large energy tariff savings of IDR 9,602,764,579,345 and a payback period of 7 months. In Fiberline 2, it shows the amount of energy saved when the motor uses a VSD of 694543.902 kWh with a large energy saving of Rp. 8,307,356,266,554 and a payback period of 13 months.

Abstract

A charger controller is required in the process of charging batteries that use solar energy through solar panels. The battery charging process can use more than one battery, in this study using two batteries. For this reason, it is necessary to design a battery charging automation device with a solar energy source to facilitate the battery charging process. The charging method is run alternately on two batteries that will be charged based on the preset low voltage sensor. The initial voltage value on the battery is used to calculate the battery's State of Charge (SOC) capacity. In this study, we will observe the filling process of two batteries of 12 Volt Lead Acid types, having a battery capacity of 3.5 Ah and 7.2 Ah with a source of 100 Wp solar panels. An Arduino microcontrollers is invoked as control systems for reading voltage and current sensors as detectors during battery charging. The test results obtained that the first battery is filled with 12.3 Volt for battery voltage at 69.4% SOC reading, then 12.82 Volt second battery with 84.9% SOC reader. The duration of the first battery charging is for 90 minutes with an average current value of 0.7 Ampere at 100% battery of SOC. The second battery starts charging after the battery is full when the relay has moved automatically to charge the second battery. The duration of second battery is charging for 60 minutes with an average current of 0.17 Ampere at 94% SOC. All measurement results, during the test are run directly recorded by the data logger and stored on the SD Card.Keywords: Arduino, Control Charge, Data Logger, Current Sensor, Voltage Sensor

Abstract

The power plant is a long way from the center of the load, and this results in considerable power losses and electrical voltage on the distribution of electrical power. This loss is caused by a long electrical transmission line and the type of conductor used. In the distribution of electrical energy through transmission and distribution, a voltage drop will take place throughout the line. This study will evaluate the magnitude of the voltage drop that occurs at the Jendral Sudirman feeder in Pekanbaru, Riau. There are several methods that can be made to improve the voltage drop. So this study will use the Distributed Generation (DG) installation method in the distribution network. In the initial data collection, the voltage drop on the feeder was 18.657 kV, equivalent to 6.72%. The voltage drop value exceeded the PLN standard, which was 5% of the nominal voltage. To improve the voltage drop in DG pair on the distribution network on the general Sudirman road feeder of 19.893 kV. Finally, from the analysis obtained the value of the voltage drop becomes reduced from before the installation of DG with the DG installed. The value of the voltage drop produced is far better at 0.53%, and this value has met the standard PLN that has been set.Keywords: Distributed Generation, Power Flow, Voltage Drop

Abstract

Along with the growth of society and technological improvements, the demand for electricity continues to increase. However, the development of the electric power system is not sufficient to supply the needed electrical energy. For this reason, it is necessary to regulate and manage a good electricity distribution system so that the current growth of community needs is met and has a high enough reliability. The installation failure in the electric power system cannot be avoided due to the long transmission distance. This has a major effect on the flow of power in electric power transmission resulting in a decrease in voltage and loss of electrical power. One of the ways to overcome voltage stability and improve the reliability of the electrical power system is to use a Flexible Alternating Current Transmission System (FACTS). One of the FACTS devices is the Thyristor Controlled Series Compensator (TCSC). The TCSC is installed in series with the transmission line and is used to increase the power capabilities of the transmission line. Regulating the reactance of the transmission line can be done by controlling the reactance of the TCSC so that the power flowing can be increased. After conducting a power flow study using the MATLAB 2016a PSAT toolbox software, it was found that the voltage on the Bangkinang bus was 0.9868 p.u (148.02 kV) and on the Garuda Sakti bus was 0.9637 p.u (144.55 kV). After installing the TCSC on the Riau 150 kV transmission system, the TCSC was installed on the Garuda Sakti transmission line - Balai Pungut. The installed TCSC rating is 24 Mvar. The value of the alpha parameter is 0.2 and (-0.8) radians. After installing the TCSC, voltage stability the Bangkinang bus and the Garuda Sakti bus increased to 0.99008 p.u (148.512kV) and 0.97693 p.u (146.535kV). The percentage increase is 0.4% on the Bangkinang bus, 1.15% on the Garuda Sakti bus, the average stress on the object of research has increased by 1.15%.
