Abstract

This paper deals with power injection on single phase grid connected inverter. The simple method is introduced to understand the concept of grid connected systems. A phase Lock Loop (PLL) method estimates the phase-angle of grid system. The output of PLL is used to defines Iref , and the current of inverter becomes a feedback (IL). Both current are derived to produce PWM using current mode controller method. As long as the grid system on fault condition like voltage distortion, therefore the single-phase inverter that connected into the grid should change the role and keep stabilization. The voltages sag and swell are the possible conditions that occurred on a power system. Voltage Sag is an event where the line voltage decreases from the nominal line-voltage for a short period of time. Voltage swell is the event when the line voltage increase from the nominal line voltage. By using PSIM software, the injection and absorption of power into a grid system is verified during a voltage sag, swell, and normal. The simulation shows voltage grid vg, current inverter iinv, current grid, active power P, reactive power Q. The waveform of the measured parameter is analized to define the role of inverter toward grid. the The result shows performance of the proposed inverter to absorb reactive power during swell, and inject reactive power when sagging.

Abstract Demand Side Management (DSM) bertujuan memodifikasi pemakaian energi sehingga diperoleh efisiensi energi yang maksimal. Memodifikasi prosedur operasional peralatan listrik dengan cara yang lebih efektif juga merupakan strategi dalam memperoleh efisiensi energi. Konsumen energi listrik akan mendapatkan kepuasan dengan diterapkannya strategi DSM ini. Penerapan teknik kendali beban terpusat pada peralatan PT. Matahari Pontianak Indah Mal (PT. MPIM) merupakan salah satu tujuan penerapan DSM yang akan memberikan keuntungan berupa penghematan daya dan energi listrik. Skenario kendali beban terpusat yang diterapkan dalam tesis ini mendapatkan penghematan daya listrik yang semula bekerja 1,06MW per hari menjadi 0,65 MW per hari, terjadi penghematan sebesar 38,46% per hari. Strategi DSM yang akan diterapkan pada PT. MPIM adalah pada peralatan AHU (Air Handling Unit). Untuk mencapai tujuan efisiensi energi tersebut maka seluruh perangkat-perangkat AHU baik pada FCU maupun Blower (tombol-tombol, sensor-sensor, dan kontaktor-kontaktor) perlu dimonitor secara terpusat di ruang kendali utama. Dengan memperhatikan status tombol, sensor dan kontaktor maka teknisi dapat mengetahui jumlah AHU yang aktif dan yang mengalami gangguan. Suatu program monitor yang interaktif dibuat dengan kode sumber Program Delphi, dan dengan menggunakan koneksi kartu PPI 8255 program tersebut dapat berhubungan dengan peralatan diluar komputer, inilah cara untuk mengakomidasi penerapan kendali beban terpusat ini.

Abstract

Abstract- Electrical protection systems in Landak Regent office is inadequate and not well integrated. The analysis shows that external protection of Landak Regent office consisting of a single lightning rod installed on the building, has not been able to protect whole of the office building. Landak Regent office building length is 161,50 meters, while the calculation of lightning protection radius obtained by 73,46 meters. The results shows that there is part of Regent office building that have not been protected by the lightning rod or outside the cone incline of 7,29 meters on the left side and 7,29 meters on the right side, so we need to add another electrostatic lightning rod by changing the electrostatic lightning rod installation position on the edge of the left side and the right side of the building or increase the height of the lightning rod. Lightning rod conductor installed on Landak Regent office was meet the standart of PUIL Indonesia published in the year 2000 and meet the standard of PUIPP Indonesia which using BC 50 copper wire without insulation. The grounding resistance value is 7,8 ?, so that can be declared not good. Solution for a small grounding resistance value is by increasing the depth of the earth electrode, increasing the number of electrodes and parallelize those electrode implanted. Internal protection in the form of overvoltage protection on the computer network (LAN) LPSE room currently not ideal, because the protection which installed only using UPS. To improve the reliability of lightning protection at computer network (LAN) LPSE room, overvoltage arresters should be installed in the line before it goes into the equipment.
