ABSTRAKSimulator penggunaan energi listrik sangat membantu dalam perencanaan pasokan listrik secara terus menerus atau perlu pemadaman bila terjadi gangguan. Agar kinerja pembangkit dapat kembali normal, bertahap, dan terencana akibat mengalami gangguan, maka digunakan metoda Load Shedding. Sistem otomasi dibutuhkan untuk merealisasikan metoda Load Shedding, dan melalui simulator dapat mengurangi resiko terhadap kerusakan bila langsung diimplementasikan. PLC digunakan untuk memprediksi beban saat load shedding, sedangkan SCADA digunakan untuk menampilkan prioritas dan status beban. Load shedding 1 adalah tindakan pelepasan beban bila pada salah satu genset mengalami gangguan, sedangkan Load shedding 2 bila pada kedua genset mengalami gangguan. Simulasi sistem load shedding 1 dan 2 berhasil dilakukan pelepasan beban secara otomatis. Setelah pelepasan beban, kapasitas beban yang ditanggung genset sesuai dengan prediksi dari PLC.

In order for the generator performance to return to normal, gradual, and planned due to interference, the Load Shedding method is used.

ABSTRAKDari banyaknya strategi yang diusulkan untuk proses self-assembly pada swarm robotics, hanya beberapa grup riset berkonsentrasi di bidang ini yang mengusulkan proses paralel pada penggabungan antar robot. Tetapi, strategi ini hanya digunakan ketika sebuah robot memerlukan tumpuan dari dua robot atau lebih pada satu waktu. Berdasar pada kebutuhan untuk menyebarkan ratusan hingga ribuan robot pada satu swarm, strategi penggabungan antar robot satu-demi-satu memerlukan waktu yang sangat lama untuk diselesaikan. Di artikel ini, strategi self-assembly antar robot pada suatu swarm secara paralel diusulkan untuk mengurangi waktu proses self-assembly dengan menempatkan sejumlah robot di posisi tertentu. Saat penggabungan, robot-robot ini akan bergerak menempatkan dirinya sesuai dengan posisi akhir yang ditargetkan. Hasil menunjukkan bahwa strategi ini dapat mereduksi waktu proses self-assembly hingga setengah dari waktu yang diperlukan dengan proses penggabungan satu-demi-satu.Kata kunci: swarm robot, self-assembly, proses paralel ABSTRACTDespite the number of strategies proposed for self-assembly process in swarm robotics, only few research groups working in this area have proposed the parallel process of robots assembled each other. However, this strategy only works when a robot needs to be supported by two or more robots in a time. When deploying hundred to thousand robots in a swarm is required, the strategy of robots connecting to the structure of assembled robots in a one-by-one manner requires an extremely long time to accomplish. In this paper, a strategy of parallel selfassembly for robots in a swarm is proposed for reducing the self-assembly process time by placing a number of robots at particular positions. While connecting, they will move to position themselves appropriately to the targeted final structure. Result shows that this strategy can reduce the process of self-assembly time up to half of the time required for one-by-one process.Keywords: swarm robots, self-assembly, parallel process
在斯warm robotics上拟议的许多自组装策略中,只有少数集中研究小组在这一领域提出了类似于机器人相互融合的进程。然而,这种策略只有在机器人一次需要两个或两个以上的机器人集中注意力的时候才会使用。由于需要将成百上千的机器人部署在一个蜂群中,这种一对一的混合策略需要很长时间才能完成。在这篇文章中,并行建议将多个机器人置于特定位置,从而缩短自组装过程的时间。在合并过程中,这些机器人将自己定位在最终目标位置。结果表明,这些策略可以通过一对一的合并进程将自组装过程的时间减半。关键词:swarm robotics, self-assembly,并行进程随着时间的推移,这个策略只有在机器人需要被两个或更多的机器人支持的时候才有效。当数百架全副武装的机器人被释放到100台高级机器人上时,机器人的策略与一项极其持久的保证的结构有关。在这篇论文中,关于swarm中的机器人的一种策略是建议通过在部分位置放置大量机器人来减少自组装时间。在联系时,他们会朝着目标的最终目标前进。这个策略可能会将这个过程的自集成时间减半。蜂群机器人,自动组装,平行处理

ABSTRAKSimulator tekanan darah biasa digunakan sebagai nilai referensi dalam mengevaluasi tensimeter otomatis (NIBP monitor). Penelitian sebelumnya menunjukkan bahwa simulator tekanan darah dapat dibuat dengan menggunakan micro air pump berbasis motor dc sebagai aktuator. Namun, hasil simulasi yang dihasilkan berbeda untuk setiap merek tensimeter. Hasil analisa menunjukkan bahwa laju inflasi dan deflasi yang berbeda mempengaruhi karakteristik simulasi. Studi ini bertujuan untuk mengembangkan firmware simulator baru berdasarkan nilai pulse width modulation (PWM) dan gradien inflasi-deflasi untuk meminimalkan pengaruh tersebut, sehingga simulator dapat memberikan hasil yang sama untuk berbagai jenis dan merek NIBP monitor. Validasi dengan simulator referensi dan evaluasi dalam kondisi statis dan dinamis menunjukkan simulator yang dikembangkan cukup andal untuk melakukan pemeriksaan awal, termasuk evaluasi pengulangan hasil tensimeter otomatis.Kata kunci: NIBP monitor, PWM, NIBP simulator, gelombang osilasi, lajuinflasi, laju deflasi  ABSTRACTBlood pressure simulators are commonly used as reference values in evaluating NIBP (noninvasive blood pressure) monitors.

The analysis result showed that inflation/deflation rates do affect the simulation’s characteristic. This research aims to develop a new simulator firmware based on pulse width modulation (PWM) values and rising-falling slope to minimize the corresponding effect so that the developed simulator could generate the same result for various types and brands of NIBP monitor.

Hasil yang didapat dari simulasi saat terjadi kenaikan tegangan 110% adalah 0,57 detik dan saat 130% adalah 0,105 detik. Sedangkan untuk setting relay tegangan saat terjadi turun tegangan 50% adalah 0,125 detik dan saat 80% adalah 1,25 detik. Hasil simulasi dengan standar PLN tidak jauh berbeda, waktu yang diterapkan PLN ketika naik tegangan 110% adalah 2 detik dan saat 130% adalah 0,1 detik kemudian untuk turun tegangan 50% adalah 0,1 detik dan saat 80% adalah 1 detik.Kata Kunci: Generator, Daya Balik, Proteksi, Setting, Relay ABSTRACTIn this study the authors perform calculations, simulations with software ETAP 12.6.0 and then compare the results of simulation with standard PLN. On setting power relay writer applying standart IEEE C37.102-2006, generator reverse power capacity 2 x 2.5 MW is 50000 watt with relay time delay 10 second. While reverse power for generator capacity 4 x 0,7 MW is 14000 watt with a 10 second delay time. The results obtained from simulation when there is a 110% increase voltage 0.57 seconds and when 130% is 0.105 seconds. As for the setting of voltage relay when there voltage drop of 50% is 0.125 seconds and when 80% is 1.25 seconds. The result of simulation with PLN standard is not much different, the time applied by PLN when the voltage rise of 110% adds 2 seconds and when 130% is 0.1 seconds later to drop the 50% voltage 0.1 second and 80% is 1 second.Keywords: Generator, Reverse Power, Proteksi, Setting, Relay","PeriodicalId":344430,"journal":{"name":"ELKOMIKA: Jurnal Teknik Energi Elektrik, Teknik Telekomunikasi, & Teknik Elektronika","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124185751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
