Abstract

The Reliability and the quality of electric energy is not enough to make a consideration in deciding which power plant is choose in the utility business. Some of the power plant operated in Central Java still using power plant that has expensive generating cost, especially  steam and gas power plant (PLTGU). In order to make economically viable, there must be calculation on generating cost and make some optimization through reconfiguration of power plant using Digsilent simulator. Filled with conductors  capacity, power plant capacity, and the load, Digsilent will calculate the load simulation. When PLTGU block 2 not operated, so IBT 500/150 kV  Ungaran  1  and  2  suffer  overload for 103%, causing voltage drop to 134 kV. After some reconfiguration simulation, the load in IBT 500/150 kV Ungaran 1 and 2 drop to 76%, while the voltage maintain to 140 kV. Decreasing the production cost as much as Rp.107.600.400.000,- in a month. Keywords: PLTGU, Optimization, Digsilent, production cost

Abstract

The design of room temperature control using conventional technology such as PID are not simple since using complex mathematics calculation. The fuzzy logic control implemented as a temperature control need a simple design and calculation. The temperatur sensor PmodTMP3 equipped with Infrared sensor to detect the amount of people to get appropriate speed of evaporator motor in order to meet the temperature setting. My RIO 1900 with LabView 2015 use as controller.  The  DC  motor  start  to  rotate  when  sensor  counted  35  people entering the room (2,6 volt). And when 40 people entering the room, the voltage rise to 5 volt. This prove that fuzzy logic control working appropriate. Keywords: temperature control, fuzzy logic, myRIO1900
