Abstract

Upgrade network conductors to reduce voltage drop to improve service quality and reduce the effects of power loss. The system voltage is distributed to the network at a voltage of 380/220 volts and then to the residents' apartments. Due to the load supply from a single-phase system, this unbalanced load condition eventually causes current to flow in the neutral phase (leakage current) and to ground. The simulation was carried out using the tidal analysis method from the ETAP (Electric Transient and Analysis Program) 16.0 application. The voltage drop on the power grid affects the quality of the operating voltage received from the power company. If the voltage drop is not in accordance with the standard (SPLN No. 1 of 1995), the quality of the operating voltage may decrease and power loss may occur. If the state of the system is truly in a state of equilibrium, the existing power losses will only occur on the R, S, and T channels. To find power losses in a 380 V voltage network, it is necessary to know or determine the impedance, phase, and current. neutral and look for power losses in the load. Therefore, to overcome the power losses from unbalanced loads, the load balancing method is used. Based on engineering and measurement data, simulations were carried out to obtain standard compliance results for operating voltage quality and reduce voltage drop effects. Increasing the cross-sectional size of the conductor improves the simulation of the electrical aspect. To find power losses on a 380 V voltage network, it is necessary to know or determine the impedance, phase, and neutral current and look for power losses in the load.

Abstract

A direct current generator is an electrical system that converts mechanical energy into electrical energy dynamically. An independent and separate excitation type DC gener-ator is a field generator that can be connected to a DC source independently of the en-gine. When a DC voltage is introduced into the field coil in the form of resistance Rf, a current If is generated and flux is created at both poles. In this study discusses a new control system in a generator that is given a load, the generator output voltage is re-duced. The so-called mechanism in regulating the excitation voltage to control the out-put voltage. When the generator is equipped with a PLC operating at the same field voltage, the induced voltage is greater; for example when the voltage is 14.01 Volts or 15.41 Volts, the induced voltage is 34,311 Volts or 51,587 Volts.

Abstract

As it is well known that tomatoes have different qualities and colors of ripeness, it is very necessary for a farmer to sort the tomatoes because then the farmers can target the marketing of tomatoes among the market, supermarkets, etc. Sorting tomatoes manually requires good concentration so as not to cause sorting errors, but sometimes concentration can be reduced due to sitting too long, etc., so that sorting occurs at will without paying attention to the tomatoes and this can also take a long time. To overcome this problem is to offer the manufacture of a tomato fruit sorter automatically by applying the Sugeno fuzzy logic method, which is a cryptic method which means that a value can be between true and false. With this tool can overcome the problem of sorting tomatoes and can minimize time. This Sugeno fuzzy logic method is used and utilized in processing the value of tomatoes in the form of RGB values. The result of this research is a tool that is able to sort tomatoes according to conditions, namely ripe, half-ripe, and unripe.
