This research uses an Artificial Neural Network (ANN) method to estimate fault location based on the coordinate point. The 150 kV transmission system is modeled using the Matlab R2016a software. The modeled transmission system is the transmission from Koto Panjang (KP) bus to Garuda Sakti (GS) bus in Riau Province with 64,11017 Km length. Min – max normalization method is used to process the peak value of the voltage phase (VA, VB, VC), current (IA, IB, IC) and zero sequence current (INOL). ANN estimation is used to estimate the coordinate point of fault that occurs on electrical transmission line. The training and testing data are generated by simulating each type of short circuit in Matlab/Simulink R2016a with variation of fault location. Variation of fault location are based on distance of tower from the KP bus. The obtained result from 10 ANN estimation testing are coordinate point estimation in latitude and longitude form. The ANN model that has smallest average error percentage is the ACG fault ANN model, which is 0,004013 % and the largest is the ABG fault ANN model, which is 0,78527 %. The output of the ANN estimation then denormalized and plotted to the actual map using ArcMap 10.4.1.

Along with the growth of society and the improvement of technology, the need for electric power continues to increase. However, the development of the electric power system is not sufficient to supply the required electrical energy needs. For this reason, it is necessary to regulate and manage a good electricity distribution system so that the current growing needs of the community are met and have high reliability. Installation failure in the electric power system cannot be avoided because the distance between the generator and the substation is very far, this causes the voltage on the receiving side to decrease. To increase the voltage and power factor it is necessary to install a capacitor bank. Capacitor bank installed in parallel to the substation load. The results of research and simulation of Matlab Simulink capacitor bank condition 2 Ã— 25 MVAr with output voltage is 146 kV, current is 470 A and power factor is 0.93 lagging.

Solar cells as one of the new renewable energy sources have an important role in terms of meeting the needs of energy. For this reason, solar cells are employed as an alternative source of electricity generation, both in an off-grid or on-grid state. In this papers presents a step-by-step simulation of a three-phase circuit connected to a network with a solar cell source. The capacity of the solar cell to be simulated is 100 kWp. In this study, solar cells as an alternative generator that will generate three-phase AC loads. This requires a DC-DC boost converter to increase the output voltage of the solar cell and keep the voltage stable during the generation process by tracking the maximum power point using MPPT to extract the maximum power obtained from solar irradiation and channel it to the network. In systems based on solar cells, the inverter is a very critical component for controlling the flow of electricity by converting DC voltage to AC voltage and a grid load of 20 kV. In this case the distribution transformer load is 20 kV. Based on the simulation results with different levels of solar irradiation the voltage obtained is 19,473 V, then the expected voltage to generate a three-phase AC load that is the distribution load of the 20 kV transformer is reached. Simulation models are proposed in Matlab / Simulink 2016a Keywords: Solar Cells, Maximum Power Point Tracking, DC-DC Boost Converter, Grid

The aim of this research is to design a Distributed Generation (DG) connected system with solar cell source using Matlab/Simulink R2016a, build a Phasor Measurement Unit (PMU) connected to DG using Matlab/Simulink R2016a, operate a DG system connected to solar cell for monitoring voltage and phasor currents through PMU. This research was conducted using simulations found in the Matlab R2016a application where the system consists of 4 buses, 2 loads with a voltage of 20 kV, 2 voltage boosters, 20 kV, and 4 transmission lines. The results showed that the impact of the DG system using this PMU has improved the quality of the power generated from both sources, namely the 150-kV network and the DG supplied at both loads. In addition, the results of this data prove that DG has a role in maintaining power at a stable load and increasing energy efficiency by reducing power losses in this DG connected system. The DG connected to the system has an effect on increasing the current in each bus, so that the load current has increased from before, giving an effect on increasing the voltage in each bus, so that the voltage on both loads has increased from before. This comparison also shows the results of the positive sequence value of phasor currents and phasor voltages before and after DG Keywords: Distributed Generation, Phasor Measurement Unit, solar cell

Renewable energy from solar cells is a type of alternative energy for consumers, especially those far from electricity, and saves electrical energy. This research developed an innovative tool for portable solar power generators as a source of energy, which stores electrical energy in two ways, namely solar cells and transformers. Furthermore, this research is expected to improve innovation tools for more efficient electricity supply and energy use, especially for rural communities. It also uses a variety of battery capacities to test portable power supplies. The results showed that the power supply using 100 Wp solar cells produced a capacity of 20 Ah, 60 Ah, and 100 Ah on the battery. Charging with a solar energy source on a 20 Ah battery takes a duration of 5 hours to be fully charged, while 60 Ah and 100 Ah batteries cannot be fully charged in one day. Charging a battery that has been run at a full level takes a duration of 15 hours at a temperature of 30oC to 34oC. Finally, this tool is expected to add variety to locally manufactured products.

In this topic research was provided about the backpropagation neural network to detect fault location in transmission line 150 kV between substation to substation. The distance relay is one of the good protective device and safety devices that often used on transmission line 150 kV. The disturbances in power system are used distance relay protection equipment in the transmission line. However, it needs more increasing large load and network systems are increasing complex. The protection system use the digital control, in order to avoid the error calculation of the distance relay impedance settings and spent time will be more efficient. Then backpropagation neural network is a computational model that uses the training process that can be used to solve the problem of work limitations of distance protection relays. The backpropagation neural network does not have limitations cause of the impedance range setting. If the output gives the wrong result, so the correct of the weights can be minimized and also the response of galat, the backpropagation neural network is expected to be closer to the correct value. In the end, backpropagation neural network modeling is expected to detect the fault location and identify operational output current circuit breaker was tripped it.
