Abstract

Using non-linear load in UPS (Uninterruptible Power Supply) can cause harmonic distortion which will eventually have the effect on power quality. The research was designed as a single-turned passive filter to cope with harmonic distortion in UPS. In this phase, THDv, THDi, and IHDi were measured in UPS. MATLAB/Simulink was used for simulation of filter testing. After Single Turned Passive Filter was installed, the third order of harmonic current decreased from 47.69% to 7.08% or reduced 40.61%

Abstract

With the development of technology, then every industry is eager to make tools that can help employees and industrial management, one of which is a tool in the field of control. In the world of palm oil industry, oil control is needed to control the flow of oil to the plant. With automatic oil control, the oil flow rate to the plant can be controlled according to the needs of the plant. Currently there are still many palm oil industries that have not controlled the oil flow pump automatically. Although the industry includes a large industry, it still uses manual control. Then comes the idea to design the pump control automatically by using PLC. Here the test by raising and lowering the frequency for motor pump speed can change. From the test results that have dilakuakan can be concluded that a pump that is given a frequency greater than the frequency given by PLN, then the pump speed will increase according to the given by the PLN, then the pump speed will decrease according to the frequency given by the inverter. But if the pump is given a frequency smaller than the frequency frequency given by the inverter. In the simulation of controlling and monitoring the flow of oil by changing the speed of the pump can be applied in the industry, because the control in this way is very simple and can be applied in the palm oil industry

Abstract

Energy distribution of electricity to consumers are sometimes susceptible to interference, both internal and external threats. Due to a disturbance sometimes consumers feel particularly aggrieved General Hospital because it can disrupt the operational process including Muhammadiyah General Hospital. Therefore, a lot of the General Hospital that use generators as a backup energy when there is a sudden interruption of PLN. However, for the operation of the generator and energy costs are not small. This study aims to determine how much energy use efficiency ratio of the electric generator to the electricity energy in terms of technical and economical at the General Hospital in the North Sumatra Muhammadiyah Mandala By Pass Medan. Given the comparative assessment, expected General Hospital, North Sumatra Muhammadiyah can make efficient use of electrical energy so as to reduce financing for the electricity.
