Abstract

Disturbances are generally in the form of short circuits which produce large short-circuit currents, so a protection system is needed to be able to minimize the extent of the impact of the fault current. In medium voltage networks, protection is needed to secure the network from interference along the conduit. The problem that often occurs in medium voltage network systems is sympathetic trip disorder, namely the failure of the relay in the uninterrupted feeder to join the trip together with the interrupted feeder. This incident occurred in the Windu feeder when there was a short circuit interruption of the single phase of the ground feeder at the Kosambi Duri Substation. Based on these events will be discussed how the influence of the disturbance current flowing to the point of disturbance and passing through the feeder relay, for that reason there needs to be an analysis related to setting the working time of the ground relay on the feeder. From the calculation results when there is a disturbance in the compact feeder where the ground work time relay is worth 0.294 seconds (working) and for Windu feeder when the compact is disturbed it is -0.333. This minus value means that the relay should not work. It is suspected that Windu's feeder sympathetic is caused by an increase in phase voltage and creates new interference.

Abstract

Power shrinking events in the distribution network are unavoidable events, but the amount of power shrinking that occurs can still be overcome or suppressed to a minimum for that is the need to prevent the onsanion of large amounts of shrinking by means of maintenance and repair of distribution system equipment, the calculation of power shrink is carried out by quantitative method where the data retrieved is the peak current time data. From the results of the study conducted in The Bronze Purgator obtained a daily average shrinkage value of 5.37%, and the calculation result was obtained that the average energy shrinkage that occurred within a month was 3981,717 kWh.

Abstract

Untuk mendukung program Pemerintah dalam pencapaian target 23% EBT pada bauran energi nasional tahun 2025, salah satu pendekatan yang dapat digunakan adalah memasangkan pemanfaatan sumber energi terbarukan lokal untuk mendukung pengembangan perekonomian lokal di banyak pulau-pulau di Indonesia yang selama ini belum teroptimalkan. Hal ini juga akan mendorong target ekonomi maritim untuk dapat berkontribusi sebesar 9% terhadap PDB nasional pada tahun 2030, dan sekaligus menciptakan sustainability dari saling ketergantungan antara sistem penyediaan energi dan kegiatan ekonomi yang memanfaatkannya. Penelitian ini akan melakukan tinjauan awal yang sederhana dengan memodelkan integrasi sistem PLTS berskala besar sebagai sumber energi terbarukan lokal ke dalam sistem tenaga listrik konvensional seperti PLTU dan PLTD yang banyak digunakan untuk melistriki pulau-pulau tersebut. Masih dalam rangka mengoptimalkan sumber energi terbarukan lokal, untuk mengimbangi sifat intermittent dari output sistem PLTS yang tergolong sebagai variable renewable energy (VRE), PLTA Pumped Storage (PLTA PS) yang memanfaatkan air laut akan dipilih sebagai sistem penyimpan energi yang PLTA-nya sekaligus mampu mengimbangi variasi output maupun fluktuasi yang terkadang ekstrim pada saat-saat tertentu. Penelitian ini akan berfokus pada pemodelan dari skema operasi serta perubahan dari skema formulasi economic dispatch untuk sistem pembangkit termal (PLTU dan PLTD) dengan adanya integrasi sistem PLTS berskala besar ke dalam jaringan. Pemodelan akan menggunakan sistem yang sederhana untuk memberikan pemahaman dasar terhadap fundamental skema operasi sistem konvensional yang menerima integrasi sistem VRE dalam rangka mengoptimalkan pemanfaatan sumber energi terbarukan lokal yang berpotensi untuk dikembangkan di ribuan pulau-pulau di Indonesia. Hasil simulasi menunjukkan energi terbarukan lokal dari kombinasi sistem PLTS dan PLTA PS yang dioperasikan sebagai must-run units, dan pada formulasi economic dispatch diperlakukan sebagai beban negatif, yang pada akhirnya bersifat mengurangi konsumsi bahan bakar fosil pada sistem tenaga listrik tersebut.

Abstract

Load unbalance in an electric power system often occur to meet consumer needs. Distribution of the load that was initially evenly will experience an unbalance when the burdens. As a result, current arises in the transformer neutral, current flowing in the transformer neutral causes losses, losses in the neutral conductor transformer and current flowing to the ground. Technically, if these losses occur continuously, it will be detrimental to PLN and can reduce transformer efficiency. For the supply of electricity to remain stable and continuity, it must be overcome

Abstract

Ping pong ball throwers are used as automatic ball shooters as a method of self-training and training the skills of professional athletes. By adding wireless communication, ping pong ball throwers can be controlled remotely. The controller interface is created using the App Inventor so that controllers can be carried out via smart phones. To get the ball throwing “service” required a combination of parameter values of the speed of the ejection motor and the angle of the servo motor.
