Abstract

The generator is a source of electrical energy that will be distributed to the substation which will then be channeled back to consumers. The separator is the equipment at the substation which supports the performance of the equipment. Maintenance on the separator should be maintained on a regular basis which consists of cleaning and testing. One of the tests is contact resistance. This test is carried out to determine the resistance value of the Separator contact according to the standard. Power loss is affected by a high resistance value, because the power loss is the square of the current multiplied by the resistance of the contact. This study was conducted to determine the value of contact resistance against power loss by comparing the value of contact resistance in 2020 and 2021. The power loss obtained is relatively small, namely the highest power loss is in the 2021 phase R, which is 6.417 Watt or 0.006417 kW. Meanwhile, the lowest power loss is in phase T in 2020, which is 2.603 Watt or 0.002603 kW. The effect of contact resistance in this study is that if it is found that the contact resistance value exceeds the standard so that a high contact resistance value is obtained, it will be able to cause the equipment to become hot, and when it reaches its melting point, it will be able to melt the separating knife or disconnecting switch, so that the temperature does not change. can be held back by the contact resistance according to its ability, there will be an explosion at the Separator contact which will cause a trip.

Abstract

It is undeniable that the low value of the power factor can cause problems with the electrical load in the form of power consumed that does not match the installed power. A low power factor can cause power usage to be less than optimal and current increase so that it can result in increased heat losses in the cable. From the data, there are still many customers who have a power factor of 0.5 to 0.7 meaning they are below the standard, for this reason it is necessary to improve the power factor value by installing capacitors where it is necessary to calculate the capacitor’s capacity according to the installed power, so as to optimize the distribution of funds and reduce heat losses from the conductor so that the distribution condition is more stable. The diagram method is used, a diagram showing the kVAR value is needed before and after compensation. With the improvement of the power factor in accordance with the standard, a more optimal use of electric power is obtained. From the results of the calculations, the average capacity of the capacitor used for household customers with a power of 6600 VA is or 37.4 F.

Abstract

Every measurement of electrical energy has a vital and very decisive role. Kilo Watt Hour (kWh) meter is an equipment used to measure a value or price of electricity usage (watt hour) in the period of time used. The problem of losses that occur in the kWh Meter is one of the problems. The problem faced is how to make readings and measurements of the use of electricity measured properly. In this study, the objectives to be achieved are to find out when the kWh meter deviation calculation shows results of no more than the permissible kWh deviation tolerance, namely -2% and +2% results and to correct electrical energy losses, ranging from technical and non-technical kWh meter errors. technical. Based on the results of research conducted using manual calculations and using special software. With the software makes it easier for studies to be carried out. In this case, it is the non-technical determination of kWh that usually accounts for the biggest losses, because this is not 100% pure damage from the kWh Meter, but there are PLN Consumers who are not responsible for the losses given. From the results of technical testing of the 3 kWh Meter which obtained data and specifications up to the deviation of the kWh Meter and from the results of studies conducted on non-technical testing, it turns out that this is what contributes to losses on a large scale.

Abstract

Pusat pengatur beban menggunakan Automatic Generation Controller (AGC) sebagai regulasi frekuensi real time untuk memastikan keseimbangan antara permintaan beban dengan ketersediaan pembangkitan. Ketidakpastian variasi beban, dan adanya keterbatasan respon pembangkit (GRC) mempengaruhi respon dinamik frekuensi sistem dalam periode menit. Sistem Jawa Bali menerapkan AGC menggunakan metode integrator dengan 51,18 % partisipasi aktif pembangkit. Penelitian ini mengusulkan AGC menggunakan metode PID controller dengan mempertimbangkan variasi karakteristik beban dan keterbatasan ramp rate up/down pembangkit. Pemodelan AGC menggunakan PID controller memberikan respon pemulihan lebih cepat 2,3 detik dibandingkan metode eksisting dan mengelola kenaikan pembebanan lebih besar pada pembangki dengan biaya lebih rendah. Pembatasan ramp rate up/down pembangkit mengakibatkan perbedaan waktu dalam respon pemulihan dan berpengaruh pada fluktuasi frekuensi sistem, sedangkan variasi karakteristik beban tidak banyak mempengaruhi respon dinamik frekuensi sistem. Metode yang diusulkan disimulasikan dengan menggunakan Matlab Simulink dengan pemodelan untuk 2 pembangkit pada kontrol area tunggal dengan variasi karakteristik beban dan pembatasan pembangkit menggunakan data-data Sistem Jawa Bali

Abstract

Transformer efficiency is defined as the ratio of the incoming power to the outgoing electric power. Even so the ideal transformer has 100% efficiency, this ideal transformer does not exist, because the energy that goes out is always less than the energy that goes in, meaning that there is energy loss. Load imbalance in an electric power distribution system always occurs and the imbalance is in single-phase loads in low-voltage network subscribers. Due to the load imbalance, a current appears in the neutral of the transformer. Perform analysis and compare efficiency. Analysis of used load capacity is not efficient. Analysis of the results of current and voltage measurements at the substation to obtain efficiency, and transformer losses in day and night conditions using LWBP and WBP methods. In this study, observations were made regarding the transformer efficiency analysis using the Outside Peak Load Time (LWBP) and Peak Load Time (WBP) methods. The LWBP method is carried out during the day for 20 hours, while the WBP method is carried out at night for 4 hours, from 18.00 to 22.00. Then measurements were made at PT. PLN (Persero) UP3 Garut. For the highest percentage of loading which is close to the standard of 80%, namely the afternoon loading at the PDDK substation, which is 50.93%, the load used is 50.93 kVA. The night load at the CITL substation is 77.49%, the load used is 77.49 kVA. For the lowest percentage of loading that deviates from the standard 80%, namely the daytime loading at the SJRK substation, which is 16.32%, the load used is 16.32 kVA. The night load at the SJRK substation is 21.52%, the load used is 21.52 kVA. Based on observations, it is not efficient because the unused load is very large, it is recommended to use a smaller transformer capacity. The highest efficiency in the LWBP method is at the CITK substation 97.87%, the lowest at the PDDK substation 94.55%. The highest efficiency in the WBP method is at SJRK substations 95.5%, the lowest at PDDK substations is 92.1%.
