Abstract

The development of power electronics converters has been widespread in the industrial, commercial, and home applications. The device is considered to produce harmonics in non-linear loads. Harmonics cause a decrease in power quality in the electric power system. To prevent a decrease in power quality caused by harmonics in the power system, the detection of harmonics has an important role. Therefore, this paper proposed feed forward neural network (FFNN) for harmonic detection. The design of harmonic detection device is designed with a feed forward neural network method that it has two stages of information processing, namely the training stage and the testing stage. FFNN has input harmonics and THDi as output. To detect harmonics, frst training is conducted to recognize waveform patterns and calculate the fast fourier transform (FFT) process offline. Prototype using the AMC1100DUB current sensor, microcontroller and display. To validate the proposed algorithm, compared by standard measurement tool and FFT. The results show the proposed algorithm has good performance with the average percentage error compared by standard measurement tool and FFT of 5.33 %.

Abstract

Pembangunan kepariwisataan dikembangkan dengan pendekatan pertumbuhan, pemerataan ekonomi untuk kesejahteraan rakyat dan pembangunan yang berorientasi pada pengembangan wilayah, yang bertumpu kepada masyarakat dan bersifat memberdayakan masyarakat yang mencakupi berbagai aspek, seperti sumber daya manusia, pemasaran, destinasi, ilmu pengetahuan dan teknologi. Pada pengabdian ini melakukan pengambangan pariwisata pada aspek destinasi, ilmu pengetahuan dan teknologi. Dimana destinasi atau lokasi pada pengabdian di Dusun Paras, Desa Kembangbelor, Pacet, Mojokerto, Jawa Timur yang merupakan desa wisata edukasi. Desa ini memiliki program-program desa yang ingin mengembangkan pariwisata di aspek ilmu pengetahuan dan teknologi, maka digandenglah mitra Desa Kembangbelor khususnya Dusun Paras. Pembangunan sistem Pembangkit Listrik Tenaga Surya (PLTS) beserta penyimpanan energinya untuk dimanfaatkan sebagai penerangan jalan umum (PJU) dinilai cocok sebagai pengembangan pariwisata desa dalam aspek ilmu pengetahuan dan teknologi. Karena disisi lain mendapatkan kedua aspek tersebut, hal ini juga mendapatkan pemanfaatan energi terbarukannya untuk PJU jalan masuk desa yang belum ada penerangannya. Dengan adanya sistem yang dipasang masyarakat mendapat pemanfaatan energi PLTS untuk PJU dan tempat untuk belajar untuk wisata edukasi berupa ilmu pengetahuan dan teknologi mengenai energi terbarukan PLTS.

Abstract

The lighting system is one of the biggest uses of electrical energy. Currently, lighting systems, especially emergency lighting, are urgently needed to deal with sudden blackouts at night. The emergency lighting gets a source of electrical energy from the battery and the battery gets a source of electrical energy from PLN. To regulate the source of electrical energy, a DC-DC converter with a bidirectional method is used. The bidirectional converter is a converter that has 2 functions, namely buck mode and boost mode which works when the main source of PLN goes out, automatically the lighting system will be supplied by the battery as a backup source. The buck mode in the charging process is used to store electrical energy into a battery with a battery capacity of 12V 30Ah. While the boost mode in the discharging process is used to distribute electrical energy from the battery to the load with a lamp load of 10W. The charging and discharging processes are controlled using proportional integral control analytic methods. The charging process in buck mode with a Kp value of 8.62 and Ki of 17240, the output voltage value is 13.99V. While the discharging process in boost mode with a Kp value of 2.44 and Ki of 344.63, the output voltage value is 23.99V.
