(2), for the relevant apparatus in the SV network of intelligent substation or GOOSE network, send on the self-inspection information of relevant apparatus being carried out by GOOSE or MMS, network message record analysis device obtains corresponding message information and carries out comprehensive analysis and judgement.
Further, wherein, for the relevant apparatus in SV network, comprehensive analysis and judgement are carried out from three aspects:
(1), for the alarm of protection SV Sampling interrupt: consult net and divide or Sampling interrupt alarm is sent in observing and controlling whether, if do not uploaded, so between merge cells and protection, link is abnormal, if uploaded, so merge cells link broken string;
(2), for a net point SV Sampling interrupt alarm: consult in protection or observing and controlling whether and send Sampling interrupt alarm, if do not uploaded, so between merge cells and net point, link is abnormal, if uploaded, and so merge cells link broken string;
(3), for SV format alert: judged whether to configure in APDU and ASDU format error, SV message relevant parameter mistake, SV message transmission frequency and SCD inconsistent, if had, then merge cells configuration error.
Further, wherein, for the relevant apparatus in GOOSE network, comprehensive analysis and judgement are carried out from three aspects:
(1), for protection GOOSE chain rupture alarm: consult net and divide or GOOSE chain rupture alarm is sent in observing and controlling whether, if do not uploaded, so between intelligent terminal and protection, link is abnormal, if uploaded, so intelligent terminal link broken string;
(2), for net point GOOSE chain rupture alarm: consult in protection or observing and controlling whether and send GOOSE chain rupture alarm, if do not uploaded, so between intelligent terminal and protection, link is abnormal, if uploaded, and so intelligent terminal link broken string;
(3), for GOOSE message format detection: judged whether that GOOSE detects multicast address error, GOOSE detects VLAN numbering mistake, GOOSE detects APDU and ASDU format error, GOOSE detects relevant parameter mistake, if had, then intelligent terminal configuration error.
The intelligent alarm of intelligent substation of the present invention and comprehensive judging method obtain the various warning information of other each secondary devices to realize the diagnosis of communication network failure in transformer station by the network message record analysis device of transformer station, for accident analysis in transformer station provides effective data supporting, realize the communications status assessment and analysis of the whole network.
