Research for data acquisition equipment with Micro-Grid system

Micro-grid system, which is connected with power system, should not affect on power quality. Therefore, micro-grid system needs to control system to minimize effect of power quality. In this paper represents the measurement equipment for voltage/current of micro-grid system and the result. This system monitors the state of micro-grid system, such as steady state, islanding operation and reconnection with conventional power system. The equipment has real-time measure function and communication with PC via USB port. This equipment can use various purposes such as investigation of transient state, monitoring of real-time operation and evaluate the power system quality.
