New Information Interface Scheme for Substation Monitoring Information Based on E Language and IEC104 Protocol

In view of the lack of unified standards for substation monitoring information point table, and the absence of output interface of monitoring data in the substation monitoring system, the requirements of automatic verifying cannot be meet. Based on the E language standard, the monitoring information point table format on the basis of the remote configuration description of the data communication gateway is defined and a protocol for the monitoring information exchanging is extended to form based on the 104 protocol and substituted service of IEC61850, so as to realize the release of monitoring data and the access of simulated signal activation. The practical application shows that the method can realize the standardized export of monitoring information point table and the monitoring information interaction between monitoring system and external testing system.
