Abstract

The procurement electricity increases every year, therefore concept distributed generation is used. To maintain the quality of distribution is used a good Over Current Relay (OCR) setting to overcome Short Circuit in an IEEE Modified 7 Bus Electric Power system. Relay settings used 2 calculations are manual calculations and ANN method. Adaptive relay calculations distributed generation system are divided 4 conditions. The ANN method is used to see the error value coordinate. The results calculations using the ANN method obtained MSE value 3,91e-14. Total TDS and IPickup results in condition 1 are 1,355328s and 38,6715, in condition 2 are 1,199314s and 35,5915, in condition 3 are 1,30228s and 27,1915 and in condition 4 are 1,17221s and 24,304. While the results ANN method in condition 1 are 1,355349s and 38,671495, in condition 2 are 1,199338s and 35,591495, in condition 3 are 1,302281s and 27,191494 and in condition 4 are 1,172241s and 24,303997. The results of relay coordination in accordance with the design in conditions 1 and 2. Conditions 3 and 4 with the location fault on Bus 2 Backup relay R3 is replaced with R6, this occurs due to a change in the direction of the fault current in the system.

Abstract

This research aims to develop a system that integrates the IEEE 802.11 network and LoRa WAN in developing a wireless sensor network (WSN) in an area without public communication infrastructure. The sensor nodes were developed using ESP 8266 Node MCU with embedded IEEE 802.11 module and the sink was developed using Raspberry Pi minicomputer with LoRa module. The frames sent by sensor nodes were classified into regular data and critical data. The sensing data is forwarded by the sink to the nearest location with internet access using LoRaWAN according to their priority. Each node sent its regular frames with an interarrival time that varies from 30 seconds to 3 minutes and critical frames with an interarrival time of 1 to 5 seconds. The result shows that the delay of the network sending solely regular frames varies from 16.4 s to 602 and the delay of the network sending solely critical frames varies from 0.32 t0 1 s. When some nodes in the network send the regular frames and the other nodes send the critical frames, the delay of the regular frames drops to 1.25-1.75 s. The packet delivery rate of the system is 100%.

Abstract

The most difficult aspect of optimizing a wind farm is creating an accurate wind farm model, especially if the farm is connected to the grid. The inconsistency and unpredictability of wind speeds exacerbates this issue. When dealing with wind farms, it is possible that the reactive power addition capabilities of individual wind turbines are insufficient to meet network requirements. This is due to cable losses and line losses between the wind farm and PCC. This study employs a doubly fed induction generator (DFIG) and a Static Synchronous Compensator (STATCOM) compensator to keep the output voltage amplitude more constant. Using two PI controller loops, the STATCOM will generate reactive (capacitive) power if the DFIG voltage is lower. The STATCOM will then absorb reactive (inductive) electricity if the DFIG system voltage is greater. STATCOM's ability to regulate the flow of reactive power can increase the network's stability. By optimizing the network's reactive power, the power factor is increased and stabilized up to 0.99. In addition, the system's harmonics never exceed the 5% limit specified by the IEEE 519-1992 standard.

Abstract

Various commutation techniques, such as forced commutation, ignition angle control, and symmetrical angle control, have been developed to improve the input power factor and harmonic level. However, all of these techniques will produce only one pulse per half cycle of the converter input current, and consequently, the lowest order harmonic is the third harmonic. A comparative study of active filter converters between single pulse and PWM control has been investigated. Both converters are given identical R and RL loads to compare power factor (PF) and Total Harmonic Distortion (THD). The method used is a simulation with the PSPICE program. The performance of both rectifiers is evaluated based on the input current waveform, THD, and PF. At RL load, the input current distortion decreases drastically, with a THD of 100.67%. In PWM control, harmonics are reduced with a THD of 25.48%. The rectifier power factor in the active filter obtained PF of 0.25, whereas in PWM control, PF increased by 0.65.

Abstract

Pemasangan Penerangan Jalan Umum Tenaga Surya (PJUTS) sudah banyak dilakukan, terutama di Indonesia. Pada tahun 2018, terdapat sebanyak 252.552 PJUTS yang terpasang di 16 provinsi, sesuai dengan data dari program LTSHE yang diselenggarakan oleh Kementerian ESDM.. PJUTS telah masuk dalam program pemerintah untuk mengganti PJU yang masih menggunakan daya dari PLN menjadi PJU dengan tenaga surya dengan mengubah PJU konvensional menjadi PJUTS dapat menghemat dana pemerintah yang biasa digunakan untuk membiayai pembayaran listrik untuk PJU. Penulis merancang sistem kontrol dan Pengawasaning PJUTS pintar berbasis mikrokontroler untuk mengatasi masalah yang sering dihadapi oleh PJUTS yang sudah terpasang. Sistem ini mampu mengatur tingkat penerangan PJUTS berdasarkan jumlah kendaraan yang melewati, daya baterai, dan intensitas cahaya. Selain itu, sistem ini dilengkapi dengan fitur Pengawasaning untuk memantau tegangan dan arus baterai output panel surya, lokasi pemasangan, keramaian lalu lintas, daya lampu, status lampu, serta konsumsi daya harian, bulanan, dan tahunan. Arduino Nano digunakan sebagai kontroler utama, dan data dipindahkan ke database web melalui modul NodeMCU Esp8266 Wifi. Untuk melacak lokasi PJUTS, sistem ini menggunakan GPS GY NEOMV2.
