OPTIMALISASI DAN RANCANGAN SISTEM PROTEKSI PENUTUP BALIK OTOMATIS (RECLOSER) JARINGAN DISTRIBUSI LISTRIK 1 FASE DAYA 3KW PADA PLTMh SINGOSAREN WUKIRSARI IMOGIRI BANTUL YOGYAKARTA (Berbasis Mikrokontroler ATmega16)

MHP began many built in several areas but to obtain security comfort electrically to the load-more (overload) or other disorders that are still desperately needed extreme protective equipment that can prevent damage to the generator so that the continuity of electricity distribution services is well maintained and reliable. The purpose of this research is to design and construct a protection device (recloser) (Safety equipment impaired overload is automatically opened and closed electrical circuit) programmed with ATmega16 microcontroller in electricity distribution network 1 phase at 3kW power MHP Singosaren Wukirsari Imogiri Bantul Yogyakarta while impaired network efficiently and effectively so that security of electricity generation and distribution to be reliable as well as consumers gain the convenience of electricity. Results obtained data that includes dimensions of the channel width of 0,62 m 0,32 m height of the water discharge 0,1389 m3/second with 60% efficiency, resulting of output power in 261 watts. Water mill (waterwheel) used with the number of blades 20 pieces, outer diameter 2,1 m, diameter of 0,68 m, width 0,62 m category undershot waterwheel. While zero load, transmission using Hijet car axle with 14,3 rpm and 1.948 rpm to generator, whereas at normal load 250 watt windmill rotation 10,6 rpm and generator 1.421 rpm. Meter reading analog, digital and microcontroller has R2 = 0,953 means reading the voltage value of 3 is not much different measuring instruments. Statistical test non parametric test level matched (Wilcoxon's Signed Rank Test) with n = 20, alpha = 0,05, the measurement results the LCD microcontroller with theoretical study obtained Tcount = 45 and Ttable = 52, measurement of LCD microcontroller with gauge analog, Tcount = 28, Ttable = 52 and measurement LCD microcontroller with a digital gauge and Tcount = 39, Ttable = 52, Tcount
