Abstract

Suatu sistem tenaga listrik dapat bekerja maksimal sesuai dengan standart yang ditetapkan oleh sistem tersebut. Di wilayah kerja Rayon Tegowanu pada jaringan tegangan menengah 20 kV penyulang PWI 9, tejadi drop tegangan pada ujung penyulang, yang melebihi standart SPLN 72:1987 sebesar 5 %. Selain itu, juga terjadi rugi daya yang tidak memenuhi target Kajian Kelayakan Operasi pada PT. PLN (Persero) Area Semarang yaitu lebih dari 5%. Dengan melihat topologi jaringan di wilayah kerja PT PLN Rayon Purwodadi, didapatkan solusi memindahkan sebagian beban PWI 9 ke penyulang baru PWI 11, agar dapat menekan persentase drop tegangan dan rugi daya. Menggunakan software ETAP 7.5.0 dapat disimulasikan perhitungan beban, drop tegangan dan rugi daya tersebut. Dari hasil simulasi ETAP 7.5.0 pemindahan sebagian beban PWI 9 ke penyulang baru PWI 11, persentase drop tegangan pada penyulang PWI 9 akan menurun dari 11,85% menjadi -0,78%, dan persentase drop tegangan pada penyulang baru PWI 11 menjadi 5,49%. Sedangkan persentase rugi daya pada penyulang PWI 9 akan menurun dari  7,24% menjadi 1,71%, dan persentase rugi daya pada penyulang baru PWI 11 menjadi 4,49%.

Abstract

Muhammad Gifar Afria B, Heru Winarno, in general, a digital kWh meter that can be used to monitor the cosphi value is a 3 phase kWh meter. For 1 phase kWh meters it can only be used to monitor voltage and load usage. In this tool a 1 phase digital kWh meter prototype is made that can be used to monitor cosphi. Cosphi can be compared by comparing voltage and current signals using LM 393 IC. The reading results from IC LM 393 are compared with EX-OR IC so that high signal is obtained when voltage and current have phase difference only. The output of the EX-OR IC is inserted into Arduino to be read and calibrated so that it can be displayed on the LCD. for the process of reading the current magnitude used ACS 712 current sensor, while for the voltage sensor reading step down transformer is used with the principle of voltage divider. In this system, the Arduino MEGA 2560 microcontroller is used as a sensor reading processor that is programmed using the C ++ language so that it can be displayed on a 16x4 LCD. This digital KWH is also equipped with overcurrent protection using a 5vdc relay that is set to work with a driver in the form of an NPN transistor program on Arduino MEGA 2560. In its appearance this tool can provide information in the form of current, voltage, cosphi and the amount of power used in units of time and has been converted into units of rupiah. This tool can help read electrical instrumentation for homes that are still using analog KWH meters. In the process of measuring this device has an error rate of 0% for current reading, 0.4 for voltage reading, 0.07 for cosphi reading and 4.5% for kWh reading.

Abstract

Hanna Fury Nur Ramdany, Heru Winarno in this paper explain that inductors have an important role in the field of electronics. Many values of capacitors and inductors whose values are difficult to translate, namely when capacitors and inductors are of low value and the color of the print is less clear , also considering the human read factor  when an analog measuring instrument is used. From these problems, it is designed an inductance measuring instrument (L Meter) whose results can be directly displayed.The research method used in the manufacture of inductance meter measuring instruments is the literature method and laboratory tests using frequency variables generated or read by the oscillator circuit. The inductance measuring instrument designed in this researc is simple and meticulous measuring instrument that can be read and used by everyone. This digital inductance meter can be used to measure inductance - inductance with a level or a range of measurements between 20?H ?100mH.The lower the inductor value measured, the higher the percentage error. So that the tools designed must be able to work well. The average error ratio of an inductance meter with a standard LCR meter is 6.5%. . Keywords: Measuring, Inductor, Microcontroller and LCD DisplayReferencesMimail,B.

Abstract

Reza Rizkifadhla, Heru Winarno, in this article explains that overload shedding in incoming transformer occurs due to an increase in load current that exceeds the capacity of the transformer. If overload shedding is not handled, it will cause damage to the transformer, and even cause incoming trip feeders and a very wide blackout effect. Relay overload shedding mounted on incoming feeders works to anticipate overload shedding by deliberately releasing outgoing feeders gradually to reduce the load. This study aims to provide a simulation of the conditions of incoming feeders during normal times, during overload shedding and handling of outgoing feeders deliberately released by carrying out load maneuvers to other feeders with different incoming transformers. Maneuvers are carried out to maintain the reliability of the continuity of electricity distribution. In this study one simulation tool was designed. The design of this tool uses a relay and Arduino Mega 2560 as a control center. Arduino Mega 2560 reads the current using the ZMCT 103C sensor. The simulation is based on the overload shedding event that has occurred in Purwodadi Substation. As for controlling switching equipment and monitoring current and voltage is done using HMI with VT Scada software. In the experiment, 3 incoming normal currents were 2.2 A with a load of 5 12 VAC 5W lamps. Simulated maneuvering error, the load on incoming 3 increased to 2.60 A. This situation is considered to have reached the condition of overload shedding, relay PMT C trip to reduce the load. Incoming 3 returns back to normal, namely 1.68 A. Loads on PMT C that are extinguished are maneuvered to PMT E or PMT F which have different incoming.
