Intelligent Circuit Breaker Switch Controller Design Based on Micro-Grid Operation

This document researchs and designs an intelligent circuit breaker switch controller based on micro-network operation, it can be safely and flexibly used for micro-grid and grid switching. The controller has the basic functions of the three segments of the current protection, thermal memory, self-diagnosis, pre-alarm, real-time monitoring and so on. Further, in order to meet the needs of the smart grid, according to IEC61850 standard statute, the intelligent controller designs a communication interface unit so that it can communicate with the smart device which also complying with the IEC61850 statute. The experimental results show that the controller not only has good real-time performance, but also low cost, small size, easy to implement.
