Development of power measurement system in Simulated Micro Grid system for education

摘要

In recent years, “Smart Grid” obtains much attention. In the our laboratory, “Simulated Micro Grid System” for supporting learning of power engineering has been designed and implemented. The system helps young engineers to understand the principles of the Smart Grid technology. In this study, we have developed a power measurement system for our Simulated Micro Grid System. AD conversion is essential in the power measurement system to control components in the Simulated Micro Grid System and deliver measured data on the Web. In this paper, we have proposed two methods, AD conversion using ART-Linux and AD conversion using SH-3 microcomputer. The method by ART-Linux is used when real-time control is required. Moreover, the method by SH-3 microcomputer is used when there are many measurement targets.
