Abstract
Disclosed is communication error monitoring system and method thereof. In the present disclosure, a master lower-level device, at least one or more slave lower-level devices, and an upper-level monitoring unit are inter-connected via Ethernet, wherein the upper-level monitoring unit receives information of lower-level devices determined as with communication error from the master lower-level device to request and collect necessary data with the slave lower-level devices except for the lower-level devices with the communication error through Ethernet. And thus, a communication delay unnecessary of an entire power system is eliminated and a real time response and stability of a system is enhanced.
