Abstract

This paper aims to know how the conventional and fuzzy logic governor respons by load/disturbance changeand how the plant can achieve steady state condition after the load/disturbance change. This research usedsimulation methode which analyze respons of plant using conventional and fuzzy logic governor. In thissimulation, load changed 0,05 pu and 0,5 pu respectively.This study showed that by increasing of loads, 0,05 pu and 0,5 pu, system using conventional governor willachieve steady state condition at the instant of 30 and 35th second and have frequency deviation -0,0024 puand -0,024 pu respectively. Whereas system using fuzzy logic governor will achieve steady at the time of 27thand 33rd second, with frequency deviation are -0,0004 pu and -0,0055 pu. Generally, system using fuzzylogic governor has better performance than system using conventional governor

Abstract

This study aimed to see how the response changes in the speed DC motor and the armature current at the time of starting and stopping. The method used is a simulation using matlab software. By using the data specification n =?Dripproof type DC motors as well as testing the obtained value of ?n =55.44 rad / sec and ? =0.3518. Because value ? smaller than one, then the DC motor has a characteristic of less damped (underdamped).

Abstract

Tujuan penelitian ini adalah mendesain dan menguji hybrid panel surya type monocrystalline daya 60 Wh pada laju aliran fluida 0,027 kg/s. Dari hasil beberapa penelitian sebelumnya menunjukkan bahwa panel monocrystalline menyerap panas yang besar dibandingkan dengan yang jenis polycrystalline pada kondisi cuaca yang sama. Jika ini terjadi dalam jangka waktu yang lama, maka suhu permukaan panel akan semakin tinggi yang berimplikasi menurunnya efisiensi elektrik dan/atau konversi energi panas menjadi energi listrik akan berkurang. Oleh karena itu dibutuhkan media pendingin yang saling menguntungkan. Artinya dengan menhybrid dengan sirkulasi fluida (T) pada photovoltaic (PV) atau PVT, akan mempertahankan bahkan meningkatkan efisiensi elektrik PVT meskipun efisiensi thermal pada artikel ini masih perlu ditingkatkan. Disamping itu, arus yang dihasilkan lebih besar jika dengan PVT dibandingkan PV, sementara tegangan listrik cenderung tetap. Efisiensi elektrik maksimum PVT yang dihasilkan adalah sekitar 18,87% dengan suhu air panas sekitar 49oC, sementara yang PV adalah 10,89%. Ada peningkatan sekitar 8% yang menunjukkan hasil yang signifikan.

Abstract

One of the technologies that utilizes solar energy in delivering electric energy isphotovoltaic (PV) system. It converts solar energy into electric energy directly which is environmental friendly, non-pollution, not taking fossil fuel and low cost maintenance. Mineral Resources (ESDM) is one of the offices which uses PV system in Palu municipality. However, only 3 AC powered by non battery-PVis used in ESDM. In the future, ESDM have planned to add the capacity of PV system to supply the other AC. The objective of this study was to design PLTS system for supplying other AC and lighting especially in evening. In thiscase, sun panel capacity, battery, BCR, and inventers will be determined. This study also aims giving information about investment cost which is needed by PLTS with battery without battery and PLN. The calculation in this study used data from BMKG Meteorology Station Palu and Mineral Sources (ESDM) office of Central Sulawesi. The results showed that the capacity power for supplying Air Conditioner charge and lighting in evening was 122,54 kWh, where the systemsvoltage was 120 volt. moreover, the number of sun panel was 40 unit with capacity 200 Wp, 15 unit for battery with capacities 24v 1000Ah.Keyword : Photovoltaic design, Battery, BCR, Inverter, Early Investment

Abstract

The aim of this research is to track photovoltaic panel following sun orientation in order to obtain maximum output of the panel. This research has been conducted in mechanical and electrical laboratory. The tracking system has used dc motor that utilizes AT Mega 8535 microcontroller to control the movement of the tracking system. The movement is 15o every hour, from east to west (8 pm ? 4 am). Keywords: photovoltaic, single axis, tracking system.
