Abstract

Maintaining the quality of transportation services and reducing operational costs are some of the problems in shipping companies. This problem can be solved by several solutions. One of them is a reliable machine alarm monitoring and operation system. This study aims to provide a practical design of the ship's auxiliary engine start-stop control system and alarm system. This study uses an experimental method with a descriptive explanation of the observations. The test results show that this system is able to provide a simple, inexpensive, and efficient engine alarm system design to develop this technology for shipping companies. The PLC used is suitable for controlling this system because of its fast response. In addition, the utilized HMI can communicate efficiently with the monitoring system showing the machine parameter interface directly. Direct application of the system has been created provides technology development solutions for monitoring and controlling systems auxiliary machines for shipping companies to reduce operational cost

Abstract

The demand for electrical energy is increasing (at 2–3 percent per year). It is necessary to utilize the energy available in nature optimally and stably to fulfill electricity needs. Synchronous generators have an essential role in fulfilling electricity needs. Maintaining and improving the operational stability of the synchronous generator is fundamental to the safe and economical operation of an electric power system. The use of control methods to increase control excitation is recognized as an economical and effective way. Previous research shows there are still areas for improvement in the excitation control method. Thus, this research focuses on optimizing the automatic excitation system using the PI control method with stability analysis using the root locus. The effect of PI control on the results of the characteristics response has Tr is 1.9 s, Ts is 6.6 s, Mp is 38.95 percent, and Ess is 11.02 percent. While the generator excitation current will increase in line with the increase in load current, and the resulting output voltage will be stable with errors that occur when compared to the nominal voltage is 10.51 percent because the sensor reading is affected by a frequency that is not following the operating frequency.DOI: 10.17977/um024v8i12023p036
