In general, a substation is an electrical system that functions to convert electrical energy to be distributed to consumers in general where electricity centers are connected to air transmission lines, and air transmission lines are susceptible to interference from outside the system, one of which is a lightning strike. Where in the operation of a substation there are several important equipment, one of which is a transformer, so a protection system must be installed on the transformer to minimize interference. Lightning strikes are dangerous for the components contained in the power center. The protection system is used to protect the power system and the equipment itself from lightning surges and short circuits. To maintain reliability and ensure normal operation, specifications for arresters installed on the HV side of the Tragi Binjai substation power transformer unit with a nominal voltage of 150 kV, have been in accordance with system requirements. The maximum distance between arresters and power transformers is 28.5 meters. The distance in the field is 3 meters, the voltage that arrives at the power transformer is 480 kV and is still below the value of the transformer's basic isolation level, so that the protection of the power transformer against lightning surges is very good

This study aims to study the performance of the safety system used in distribution transformers that reduce the voltage from 20 kV to 230/400 V with a fuse cout out safety device. Where the problem that often arises in the field is a disturbance in the electrical energy distribution system which results in blackouts. The methods used in this research are field surveys which are compared with simulations in the laboratory of the electric power protection system, which aims to determine the performance of theaelectricapoweraprotectionisystem of fuse cut out in network security. Data is taken from cases that occurred at the ST 87 substation TP.02 ULP Stabat. Where the research results obtained are the magnitude of the fault current which is equal to the current rating of the installed fuse link. So that at the end of the study, several results were found where the amount of fault current had exceeded the existing transformer resistance limit, so that the transformer was damaged and disrupted the 20 kv network system.

Solar panels or solar cells are one of the renewable energy sources. Solar cells can convert sunlight into dc electrical energy. However, the main problem with solar cells is that the energy produced is not stable. The surface of the Solar cell board has a maximum temperature which affects the output of the solar cell. From this research, the writer will make the surface cooling of the solar cell board using a heatsink fan. The maximum surface temperature of the solar cell board reaches an average of 45 oC. If the temperature exceeds 45 oC it will reduce the output of the solar cell. In this study, the average temperature on the surface of the solar cell board, from 9 am to 3 pm was around 50.14oC and the average output of the solar cell reached 18.80 Volts. Meanwhile, the average temperature of the solar cell with the use of heatsink cooling is 36oC. The average output of the panel is 19.11 volts. Thus, by using a solar cell surface board cooling system using a heatsink, it has an average temperature decrease of 28.20% and an increase in output (Output) can be increased by 1.64% from the efficiency of the Solar cell which is only 12.1%.

The Generator Set consists of the Engine (Motor Propulsion) and also the Generator / Alternator, as previously explained. This engine uses fuel in the form of Diesel (Diesel Engine) or can also use Gasoline, while the Generator itself is a coil of wire made of copper consisting of a static coil or stator and is also equipped with a rotating coil or rotor. In the process of working, according to physics, the engine rotates the rotor in a generator which then causes a magnetic field in the coil section of the generator. Furthermore, this magnetic field will then interact with the rotor which will then rotate and will produce an electric current which is in accordance with Lorentz's law.

This study describes the effect of the collector cross-sectional area on the capacitance value of the four graphene super capacitors using a digital multimeter. In the first experiment, the graphene square super capacitor with a cross-sectional area of 25 cm2 resulted in a capacitance of 0.842 F. Especially the super capacitor, which is called a double layer electric capacitor (EDLC) or ultra capacitors, meet the standards for high power applications. The use of supercapacitors is very rare because of the high cost of manufacture. The graphene super capacitor that has the best capacitance is Square. The graphene super capacitor in this study was designed in several stages. Synthesis of graphene as electrode was obtained by mixing H2SO4, H3PO4, KMnO4, Graphite Powder, dried for 12 hours at 110ºC

Indonesia's electricity demand is predicted to increase every year, this can cause Indonesia to become an energy importer in the coming year. These problems can be overcome by developing alternative energy, one of which is by utilizing waste vibration energy or pressure energy from the movement of motorized vehicles, cars and pedestrians and even wind gusts in the use of piezoelectric speed bumps. Piezoelectricity is an energy harvester. Piezoelectric with cantilever mechanism produces vibration and deflection repeatedly, causing an electric voltage. The piezoelectric speed bump designed in this study consists of a speed bump system that serves to receive input from motorized vehicle pressure, piezoelectric cantilever system as a component producing electrical energy and energy harvesting system as energy harvester from piezoelectric materials. One system module consists of a parallel piezoelectric circuit connected to the MB39C811 buck converter. This paper will discuss the mechanism of design analysis and modeling of a piezoelectric power generation system on a body bluff-based speed bump with a cantilever system for variations in motor vehicle speed by means of physical modeling. In the piezoelectric bump bluff body, it can be seen that the air flow when passing through the triangular cross section increases in speed so that the resulting vortex has a high speed. This is what causes high vibrations in the piezoelectric so that the maximum voltage and the average voltage have the highest values. The piezoelectric speed bump is capable of generating electric power with an input of 60 times that of a motor vehicle above 2.166mWh with an efficiency of 2.

Direct torque control(DTC) of the induction motor is inclined to a specified value of torque. The torque provided is a speed output regulator, therefore it is mandatory to continue tuning to adjust the Kp, Ki parameters. In conventional proportional-integral (PI) speed controllers, motor performance may differ over time which may lead to torque disturbance uncertainty, causing sluggishness of the flux response so the choice of PID parameters is important for DTC systems. In this paper we present a control technique using Particle Swarm Optimization (PSO) to improve the parameters (Kp, Ki) of the speed controller to reduce torque ripple, stator flux distortion ripple and fast response of rotor speed. Unlike conventional designs, this method is capable of achieving the desired control performance. The closed-loop speed control in DTC for induction motors uses the PSO technique thus providing a practical level of accuracy. The results show good features and strong exemplary in dynamic system response and reduction in motor torque and transients.

In increasing the electrical power capacity of the Wind Power Plant (PLTB) there are several ways, among others, by increasing the number of generators, but the drawback is that the cost is too expensive because they have to build new plants. Another way is to increase the output power efficiency of existing wind power plants. One way is to use Maximum Power Point Tracking (MPPT) technology which functions to increase the output power of the power plant when there is a change in wind speed. In this paper, this technology is in charge of regulating the generator output voltage through a DC-DC converter type Cuk Converter, where the switching technique uses PWM (Pulse Width Modulation) by adjusting the amount of duty cycle. Changes in the value of the duty cycle depending on the size of the wind speed, so that to adjust the value of the duty cycle and speed up the switching response of the PWM control, a modern algorithm called the Fuzzy Logic Controller (FLC) is used. The results showed that FLC-based MPPT technology could increase the percentage of PLTB output power efficiency from 45.5% to 87%.
