Research on ZigBee Monitoring Technology of Equipment Condition in Digital Substation

Starting from the hierarchical structure of digital substation based on IEC 61850,according to the real-time requirements for equipment monitoring,and combining with the characteristics of ZigBee wireless communication technology,the ZigBee monitoring system for equipment condition in digital substation was structured.Taking digital substation switchgear ambient temperature and circuit breaker body vibration for research object,the system monitoring program,the hardware and software detailed design was introduced.This design has certain reference value for the development of digital substation.
