Vol. 7 No. 1 (2021): ANALISIS RANCANG BANGUN PEMBANGKIT LISTRIK BERBASIS MAGNET UNTUK KETAHANAN ENERGI PERTAHANAN DI MASA DEPAN

The mastery of electrical energy resource technology is one of the most important basic needs today. In this research and development activity, a magnet-based power plant is designed as an alternative energy source without fuel that can be used for defense purposes, especially by the Indonesian Armed Force (TNI). The method used in this R&D is descriptive analysis by measuring several parameters, including aspects of database engineering, preliminary design, design requirements and objectives, main propulsion system, main generating system, energy storage system, and main control system. From the calculation and function test data with a voltage of 12 VDC, a current of 20–60 A, an initial rotation of 500–2,000 rpm, at a frequency of 50 Hz which is configured with a three-phase system, a voltage of 53.694 V is obtained. As for other measurements, the results of the inter-channel voltage are 48.86 V when loaded at a rotational speed of 495 rpm and the line voltage to neutral is 28.8 V when loaded. From the further simulation test, the addition of the torque value of 13.8 Nm to 14.8 Nm produces a power of 712.45 Watt. The addition of torque from 15.28 Nm to 16 Nm produces a power of 865.8 Watt. It is hoped that this magnet based power plant will be able to be developed and applied to realize defense energy independence in the future.
