"Program yang dirancang untuk sistem 1 fasa, dapat dipergunakan untuk simulasi pengukuran nilai daya aktif, daya nyata, daya reaktif, phasor diagram, melalui Arus dan tegangan listrik AC yang dinyatakan dengan amplitudo, frekuensi, dan sudut fasa. Prosentase kesalahan hasil simulasi daya terhadap hasil perhitungan menggunakan teori daya listrik arus bolak-balik untuk setiap jenis pengukuran daya lebih kecil dari 5.10-5 %. Setiap perubahan perbedaan fasa arus dan tegangan dapat direspon secara dinamis dengan benar melalui grafik diagram phasor yang ditampilkan di panel monitor. Grafik spectrum sinyal arus untuk mengamati amplitude dan frekuensi sinyal fundamental dan sinyal harmonisa dapat merespon setiap perubahan yang terjadi dengan benar.

The program is designed for 1-phase systems, simulation can be used to measure the value of active power, apparent power, reactive power, phasor diagrams, voltage and current through the AC power represented by amplitude, frequency, and phase angle. The percentage of fault simulation results of the results calculations using the theory of alternating current electricity power every type of measurement is smaller than 5,10-5 %. Any change in the phase difference of current and voltage can be dynamically respond correctly via graphs phasor diagram shown in panel monitor. Spectrum signal flow graphs for observing the signal amplitude and frequency of the fundamental and harmonic signals can respond to any changes that occur to the right."

"Perubahan bentuk jaringan distribusi radial menjadi bentuk jaringan spindle pada GI Ciawi Bogor bertujuan untuk meningkatkan keandalan sistem tenaga listrik dengan adanya penyulang express yang dapat berfungsi sebagai suplai cadangan. Untuk menunjang sistem yang handal maka diperlukan adanya sistem proteksi yang baik. Pada sistem proteksi jaringan distribusi spindle digunakan rele arus lebih sebagai pengaman dari gangguan hubung singkat. Tahapan awal dalam menentukan setting rele arus lebih adalah dengan melakukan studi aliran daya untuk menentukan arus beban maksimum (nominal) yang melalui rele. Selanjutnya dilakukan perhitungan arus gangguan hubung singkat untuk menentukan setting arus pada rele. Skripsi ini akan membahas mengenai koordinasi proteksi rele arus lebih pada perencanaan jaringan distribusi spindle GI Ciawi Trafo 1 Bogor. Berdasarkan hasil simulasi didapatkan bahwa koordinasi antar rele telah bekerja sesuai urutan dengan waktu kerja antar rele berkisar 0,1-0,2 detik.

Changes in the radial distribution network form into the spindle network form at GI Ciawi Bogor aims to increase the reliability of power system with the express feeder which could serve as backup supply. To support the reliability of power system then it is necessary to have a good protection system. The protection system of spindle distribution network uses the overcurrent relay to protect from nuisance overcurrent. The first step of determining overcurrent relay setting is perform power flow studies to determine the maximum load current (nominal) passing through the relay. Further step is perform the short circuit fault current calculations to determine the current setting of the relay.

This thesis will discuss about coordination of overcurrent relay in the planning of spindle distribution network in GI Ciawi Transformers 1 Bogor. The result of simulations is the coordination between the relay has been working sequentially with the work time of relay range is 0,1-0,2 seconds."
