Abstract

Bus-bus beban selama ini hanya dianggap sebagai beban saja tanpa dianggap sebagai elemen jaringan. Menganggap beban sebagai elemen jaringan berarti bus-bus beban dapat dimasukkan ke dalam admitansi atau impedansi jaringan. Hasil iterasi untuk mencapai konvergen, analisis aliran daya dengan menganggap beban sebagai elemen jaringan (170 iterasi) lebih banyak dibandingkan analisis daya standar (168 iterasi). Ini membuktikan analisis daya standar pada sistem jaringan IEEE 14 Bus mempunyai tingkat iterasi yang lebih baik. Kecepatan iterasi untuk mencapai konvergensi berbanding lurus dengan tingkat iterasinya, semakin sedikit tingkat iterasinya maka semakin cepat untuk mencapai konvergen. Total rugi-rugi daya, pada pada kedua metode adalah sebesar 0.4315 + 0.6764i (pu) dengan nilai konvergensi sebesar 0.00001.

Abstract

This study discusses the effect of the hydrophobic layer on the surface of the polyethylene insulator on the leakage current and flashover voltage with variations in exposure to ultraviolet light. This research was conducted by varying the conditions of ultraviolet irradiation on the insulator, test voltage, and also the test conditions in the form of dry and wet conditions. Variations in the duration of ultraviolet irradiation were for 0 hours, 24 hours, and also 48 hours. The insulator used is also divided into 2, an insulator with coating and a non-coating. Initial testing of the contact angle to determine whether the insulator is hydrophobic. Furthermore, distribution simulations and electric field efficiency calculations were carried out using FEMM 4.2 software, so that dielectric strength values could be calculated. After that, leakage current and flashover tests were carried out with voltage variations of 4kV, 8kV, 12kV, 16kV, and 20kV. The results obtained in this study are the greater the value of the test voltage given, the greater the value of the leakage current, while the flashover voltage has an inverse relationship with the leakage current. The greater the leakage current, the smaller the flashover voltage. In insulators with a hydrophobic layer, the value of the leakage current and flashover voltage can be improved. In addition, the addition of the duration of irradiation causes the value of the leakage current to be greater and the flashover to decrease in value.Keywords— insulator, leakage current, flashover, hydrophobic, polyethylene

Abstract

From 2019 until 2020, Microhydro Power Plant (MHP) Units A1 and A2 measured a significant power decrease of more than 75% from their template capacities. Therefore, CSR PT PJ Paiton with PKSDAL Brawijaya University created a program called “Increasing The Power Capacity Of Andungbiru MHP Units A1 And A2 For The Lead Of Safe And Sustainable Electricity In 2022”. In this experiment, Unit A1 will be used as the test object, as the purpose it is to measure the success of the increasing electrical power and quality programs of Andungbiru’s MHP, especially Unit A1. The success analysis needed is in terms of increasing generator power, stability of generator output characteristics, and knowing the level of quality or efficiency of the generator after repairs and also knowing the level of stability of the generator when a fault occurs. The test is carried out in various loadings to get results that can represent the use of Andungbiru’s MHP consumers with a Dummy Load test device and a data logger with the Mod Bus Tool application with RS482 Cable Driver with load intervals of 25%-50%-75%-100%. The characteristics of the generator are considered quite good from the relationship between the variables.Keywords – MHP, Synchronous Generator, Load Variation, Electrical Impact, Desa Andungbiru, Kecamatan Tiris, Kabupaten Probolinggo

Abstract

At the Cawang Substation there are 3 types of transformers and has several feeders, one of which is the Abimanyu feeder. According to the data that we obtained, the feeder disturbance data in 2020 at the Abimanyu 22 kV feeder experienced 3 trip.In the Abhimanyu feeder, a good relay setting is needed to protect the electrical equipment contained in the feeder and otherelectrical equipment from short circuit fault and overload disturbances. Therefore, a protection system is needed which metthe requirements of sensitivity, reliability, selectivity, and speed is needed to localize the interference. All of these requirementsdepend on the accuracy of the protection equipment used in the distribution channel. The types of protection on distributionlines are overcurrent relays and ground fault relays. Therefore, there is a need for coordination between the supportingcomponents of the protection system, which consists of an Over Current Relay and a Ground Fault Relay on the Abimanyufeeder line. This coordination is intended so that when one of the busbars is disturbed or there is no safety guard that securesthe busbar it will result in an imbalance that will detected by the system and can result in the continuity of the power flow beingdisrupted. In the discussion of this writing, it aims to calculate the magnitude of the short circuit fault current that may occurin the feeder distribution of 22 kV, then determine the settings for the overcurrent relay and ground fault relay on the feeder,then simulate the system using the ETAP program 12.6 based on the results of calculations and data obtained in the field, andexamines the results of ETAP 12.6 calculations and simulations based on the settings of the Over Current Relay and GroundFault Relay on the real condition. The results of this paper can be used as a reference in making coordination of over currentrelay protection and ground fault relay at PT. PLN (Persero) UIT JBB UPT Cawang.

Abstract

Electricity is a means to support community activities both in efforts to improve welfare and to encourage economic development. The National Electricity Company (PLN) as the state electricity provider has not been able to reach the electricity network in remote villages. Andungbiru Village, Tiris Subdistrict, Probolinggo Regency is one of the areas that install PLTMH (Micro Hydro Power Plants). Due to the increase in load every year, the current conditions of the PLTMH power grid in Andungbiru village experience a more even distribution of R, S, and T phases in units 1 and 2. This situation causes very large voltage drops and loss of power to the channel so it needs to be configured to reset it. Based on the results of network configuration, phase voltage R, S, and T in unit 1 is 7,9136% V, 5,9599% V, and 6,4707% V which was previously 22,3385% V, 18,0570% V, and 47,3622% V. The results of reconfiguring unit 2 networks for falling phase voltage R, S, and T are 2,6957% V, 1,4909% V, and 0,8985% V which were previously 7.3672% V, 17,2237% V, and 13,8929% V. The power loss in unit 1 after reconfiguring the network is 2873,3886 Watts which was previously 20910,9708 Watts and in unit 2 after reconfiguring the network is 221,0193 Watts which is 1749,6933 Watts. The results of network reconfiguration can reduce voltage drop and power loss in low-voltage networks and follow the standard that the maximum voltage drop is 10% of the nominal voltage of 220V.

Abstract

Indonesia has saved 4.8 kWh/m2 or the equivalent of 112,000 GWp. This potential is the biggest when compared to the five existing types of EBT sources. However, the utilization is only a little, namely 0.08% or the equivalent of only 10 MWp. . The purpose of this study is to determine the effect of the EBT by utilizing the Arduino Mega 2560 based Solar PV On Grid System in the supply of electrical energy in the UT School Building. There are two software needed in this study which include: Arduino IDEand Nextion Editor. Based on the average test results using the RMSD measurement method which was carried out from 13 December 2022 to 28 December 2022, it was found that the potential of a 1050 Wp solar panel monitored by HMI Nextion in the UT School building produced 0.68 A and 112.69 V in the sunlight intensity 195.71 W/m2 and temperature 26.93oC. From this, it can be seen that the contribution of electrical energy generated by the on-grid EBT system monitored by the Arduino Mega 2560 is 7.33% of the total electrical energy of the UT School building. Index Terms— Solar Panel, Arduino Mega 2560, RMSD.
