Abstract

Due to its lower cost and quicker response in compassion with governor, electronic load control (ELC) has been widely used to replace governor in microhydro power plant. It has lower price and quicker response than governor. The synchronous generator used in microhydro power plant produces stable voltage, because it has been controlled by an AVR (automatic voltage regulator. If consumer loads changes, the frequency not the voltage of the electrical wave will change. Therefore, ELC is used to stabilize the electrical wave frequency and detect the change of consumer load to be transferred to ballast load. This ELC uses frequency censor to detect the change of consumer load. Frequency censor proceeses linearity level to the change of voltage which equals to R2= 0.97. The use of ELC causes the generator voltage is approximately 220,3V to 224,4V with percentage of voltage unbalance 0,56% and the geneator frequency is 49,5Hz to 50,1Hz with percentage of frequency unbalance 0,41%.

Abstract

In making of design VLSI ( Very Large Scale Integrated Scale Integration ) is needed planning of Logic Design and Layout. The function of making of Logic Design is to translate existing case study into truth tables and then it is described into logical gates. In order to make Logic Design easier, it is required a software, the name is DSCH2. It can simulate result of truth tables, beside that it has ability to make verilog file ( one of  high language program HDL ).Layout represents form of pattern to be used in making IC ( Integrated Circuit ), where form of pattern to be made have to proper by Logic Design which have been made. In making of layout used a software, the name is MICROWIND2. This software is able to read verilog file that produced by DSCH2. In this research, we build logic design and layout for basic logical gates, such as NOT, AND and SOP ( Sum of Product ). They were made from MOS and CMOS materials.
