ON-LINE AND OFF-LINE INTEGRATED ANALYSIS AND TESTING METHOD FOR SMART SUBSTATION

摘要

Provided is an on-line and off-line integrated analysis and testing method for a smart substation, which belongs to the field of tests and comprises an on-line real-time monitoring method and an off-line analysis method. An on-line monitoring part thereof effectively integrates a network communication analysis module, an SV real-time communication structure and message analysis logging module, a GOOSE real-time communication structure and message analysis logging module, an MMS real-time communication structure and message analysis logging module, and a 1588 clock synchronization module having the functions for calculating master/slave clock offset and correcting a slave-device clock in a network delay mode. Thus, a device-level and system-level testing capability for the smart substation is obtained, and the data obtained by means of the off-line analysis method is compared with the data obtained by means of the on-line real-time monitoring method, so as to further confirm whether various operating parameters of the smart substation are normal or not, thereby improving the accuracy of the overall data, and being applicable to the field of substation testing of smart power grids.
