Abstract
In order to use a generator-set for charging battery of the stand-alone hybrid renewable power generation system in remote area efficiently, the generator-set needs to be operated in various speeds considering battery voltage. The conventional field excited synchronous generator, which is used to convert mechanical power to electrical power from internal combustion engine (ICE), cannot handle this important function. Therefore, this paper presents an effective technique to improve the efficiency of the generator-set using interior permanent magnet synchronous generator (IPMSG). Two designed IPMSGs including 6 cm and 8 cm stator core lengths, which are be able to operate in the maximum efficiency speed region of the ICE, are proposed for selecting the appropriate generator in this study. Finally, the testing results show that the proposed 8 cm stator core length IPMSG with suitable operation can be effectively and efficiently used as the generator-set for charging the 48 V battery systems.
