Abstract

Changes in the load of a generator are always changing according to the needs of community demand. On the generator side of the Teluk Sirih PLTU using charcoal brush media as a reinforcing field. Where excitation plays an important role providing DC current to the generator rotor to create an intersection of electromotive forces. Changes in generator load that are always changing can have an impact on damage to equipment such as generators, and excitation. Where on December 6, 2017 the excitation current reads low at 473.7 amperes directly proportional to the armature current of 1404.2 amperes, the resulting power will also be low at 13200000 watts and a frequency of 49.9 Hz, creating a magnetic flux of 0.125 Weber that is larger or feels heavy so that the generator rotation is low at 2999 rpm and vice versa. Therefore the role of excitation takes over in order to provide greater current so that the field strength is maintained stable. Increasing the excitation current (If) results in a greater induced electromotive force (Ea). This increase in Ea also impacts the terminal voltage (Vt), causing it to vary. This relationship demonstrates that higher excitation current leads to an increase in terminal voltage, which is essential for maintaining voltage stability. To stabilize the low terminal voltage resulting from load changes, it is necessary to amplify the field gain current. This can be achieved by increasing the excitation current on the synchronous generator rotor. Understanding the characteristics of the excitation system allows for minimizing and avoiding damage to the generator caused by both overexcitation and underexcitation, ensuring the maintenance of a stable terminal voltage.

Abstract

The greater the power losses, the higher the loss costs for the transformer. These losses can occur due to load, no-load, and load imbalance factors. This study aims to obtain the cost of losses incurred due to these three factors for ten years (2023-2033). The estimated cost of losses due to unbalance is obtained from the calculation of power losses in the neutral of the transformer, the cost of no-load losses is obtained from the losses of the iron core in the transformer, In contrast the cost of load losses is influenced by the development of the load and the interest rate for each year. As a result, the greatest power losses occur under unbalanced conditions with an average load for ten years of 88.68%, followed by no-load conditions of 11.10% and 0.21% load. The total power losses for ten years amounted to Rp. 3,029,196,416.64.

Abstract

Although Indonesia has a considerable potential for New Renewable Energy (EBT), its development has not yet reached the level necessary for future optimization. The Batang Merangin River in Kerinci Regency is a location where a Micro Hydro Power Plant (PLTMH) could be constructed. Calculating the potential output of electrical power is the goal of this study. In order to fully utilize the electrical energy potential in the area around the Batang Merangin River, this research will be very beneficial for achieving regional electricity independence. The PLTMH design, which specifies the kind of water turbine (Francis) and the size of the turbine, is based on the results of measuring the water output and the height of the water fall. The research approach that will be used is a planning approach that makes use of both field research and mathematical computations. The potential power generated is quite great if the created water discharge is sufficient. The research's findings led to a 5,278.272 kW power capacity with a 43.4 m-high water fall. With the right machinery and parts, the power produced improves as more water enters the turbine in the power plant. The study's findings suggest that the effectiveness of each PLTMH component should be prioritized while planning the PLTMH.Keywords : EBT, Microhydro, Electrical Energy, Flow Rate, Francis Type Water Turbine

Abstract

The goal of the research on the effect of beam conductor distance on power losses on the 275 kV Kiliran Jao to Payakumbuh SUTET's 126.4 km long line is to determine the inductive reactance value based on power losses on inductive resistance and reactance rather than distance. The inductive reactance value is not based on the beam conductor distance of XL= 0,3111 km with a total inductive reactance value of Xtotal= 39,323Ω/km , according to the findings of the calculations performed. Based on the beam conductor distances of XR=0.238 km on distance (s)=0.06m, XL=0,3111 Ω/km on phase distance(s) = 0.26m (distance at system),and XL=0,2931 Ω/km on distance (s)=0.46m, the inductance reactance value is calculated. In the meantime, inductive reactance has a value of 34,8 MW in power loss, resistance has a value of 122 MW in power losses and capasitive reactance has a value 31,5MW in power loss. According to the calculation's findings, large currents and resistance can affect the amount of power lost in resistance, whereas the radius of the conductor wire, the spacing between conductors, and the number of layers of conductor wire can affect the amount of power lost in inductive reactance.Keywords : Conducting wire, Inductive reactance value, Power losses

Abstract

One of the most popular electric motors used today is the 3-phase induction motor, which has a sturdy design, is less expensive, and is simple to use. Improvements to the materials used in the rotor or stator of induction motors, raising the number of motor phases, and employing a 3-phase induction motor for 1-phase power are just a few of the ways the motor is now being developed to perform better. These studies are all pricey, though. The goal of this study is to determine how to enhance the motor's performance at a reasonable cost. The suggested remedy was to create a 3-phase induction motor winding with a 1-layer design that resembled a symmetrical 6-phase winding. The primary study topics were the motor's rotor speed, mechanical torque, efficiency, and winding current when it was powered by a three-phase power source. The results of the study show that, although consuming less winding current, the 3-phase induction motor with a new winding design outperforms a traditional 3-phase induction motor in terms of rotor speed, mechanical torque, and efficiency.

Abstract

Utilization of new renewable energy is a solution to meet the increasing electricity demand, one of which is solar power generation technology. Solar panels are a renewable power generator that is environmentally friendly. The relatively low and unstable output voltage of PV is affected by solar irradiation, which becomes a constraint. Therefore, by utilizing a boost converter, the solar panel system is able to work 25% more optimally compared to without using a boost converter. The performance of solar panels when using a boost converter is around 83.3% and without using it, the performance is only about 58.3%. The average output power when using the boost converter is 1,521 W, whereas without using the boost converter, the average output power is 1,172 W. This indicates that the output power is more stable when using the boost converter compared to not using it. This research focuses on a boost converter with PID control as a support, optimizer, and voltage stabilizer where the output power on the solar panel is expected to be more optimal and the output from the solar panel is more stable with more optimal results in various conditions. In this study, 12 solar panels of 125 WP with a capacity of 1.5 KW are used in series-parallel to obtain the required power. If the output from the solar panel is insufficient due to weather conditions, the voltage will be increased by the boost converter towards the inverter so that the voltage remains stable into the inverter with the boost converter. This boost converter uses PID control to keep the output voltage stable.
