碩士 === 國立勤益科技大學 === 電機工程系 === 103 === The purpose of this thesis is to develop power management and control strategies for the multi-input power source system. The study contents are classified into electric regulation for various type power converters and electric source management of DC voltage link. In order to supply power for DC load all day long, the multi-input DC sources including photovoltaic power generation system, fuel cell, grid utility power and battery are integrated. The photovoltaic power generation system can storage its excess power through charging the battery. When the photovoltaic power generation cannot supply enough power to DC load, among of the battery, fuel cell and grid utility power will serve as an auxiliary power through the electric power regulation system. The first starting auxiliary source is battery, then the second one is fuel cell, and the last one is grid utility power source. In this thesis, multi-input DC sources were constructed to supply electric power to a DC common bus for testing the performance when it supplies power to DC loads. In addition, in order to decrease volume of the hardware circuits. A TMS320F2809 digital signal processor (DSP) was used as the kernel controller for the multi-input power source system. Finally, some simulation results are made to verify the effectiveness of the proposed multi-input power source management system.
