The object of the present invention is achieved like this: the extra-high voltage DC power transmission affair alarm signal processing method, employing is with event information and the distinct mode of remote signalling state, adopt SQL Server database definition PointGroup table, the EventText table, the PointStatus table, the EventSeverity table, these tables respectively typing in advance or add at any time that all affair alarm symbols of extra-high voltage direct-current transmission control protection system may be used and the category induction-arrangement after event group, event text, state text that the event signal different conditions is expressed and seriousness grade thereof, these tables all define the keyword of numeric type; Each is waited incident symbol of signal definition of the incident that produces, the incident symbol comprises event group, event text, expressed state text and the seriousness class parameter thereof of event signal different conditions, directly choose in PointGroup table, EventText table, PointStatus table, the EventSeverity table from file server database by ODBC (connection of open type data storehouse), the incident symbol shows selected content and writes down the numeric type keyword of selected content; When control protective device or system's operation; its application program fixed cycle is checked the status signal of each incident symbol; in case the state of certain incident changes and just produces an incident, with the numeric type keyword of event group, event text, state text and the seriousness grade thereof of the state of this incident, markers and corresponding incident symbol thereof and produce an incident sign (PointID), the system of composition such as block, program page title, event signal title of this incident on duty/standby message, the time information such as target accuracy all store in the event queue.
All need not also need not define corresponding signal in SCADA system and the control protection system to the event definition Signal Message Address; During the operation of control protective device the incident in the event queue that produces is comprised that the information of above-mentioned definition is sent to the SCADA system together with its state, markers and other supplementary by the IEC60870-5-103 communications protocol of expanding; The SCADA system is inserted into event table and upgrades bug list after also receiving event message based on same expansion IEC60870-5-103 communications protocol, and warning class incident is inserted into alarm meter, the SCADA system all is saved in these information in the database, thereby makes the displaying contents of affair alarm enrich complete; Human-computer interface system defines the event of failure of list of thing, the logout that warning is tabulated, the error listing instant playback is complete, unacknowledged warning, current existence respectively.
And event information is by after the visual programming tools definition incident symbol, and the SCADA system does not need incident is carried out any configuration, greatly simplifies the configuration effort amount of SCADA system database.Redundant DC control protection system has also comprised other a large amount of supplementary by the incident that the incident symbol produces except traditional SOE information (state information and markers).
The invention has the beneficial effects as follows: event information separates fully with the remote signalling state, and its event information does not need to define the IEC60870-5-103 address, and the SCADA system does not need incident is configured.The present invention can solve the control a large amount of event definitions of protection system and revise the inconvenience that system maintenance brings to SCADA.
Embodiment
File server of system configuration is also installed SQL Server database; database definition PointGroup shows (example sees Table 1); EventText shows (example sees Table 2); PointStatus shows (example sees Table 3); EventSeverity shows (example sees Table 4); these tables respectively typing in advance or add at any time that all affair alarm symbols of extra-high voltage direct-current transmission control protection system may be used and the category induction-arrangement after event group; event text; state text that the event signal different conditions is expressed and seriousness grade thereof, these tables all define the keyword of numeric type.
When using visual programming tools editor DC control protection system application software; each is waited incident symbol of signal definition of the incident that produces; the incident symbol comprises event group, event text, expressed state text and the seriousness class parameter thereof of event signal different conditions; directly choose in PointGroup table, EventText table, PointStatus table, the EventSeverity table from file server database by ODBC, the incident symbol shows selected content and writes down the numeric type keyword of selected content.
When control protective device or system's operation; its application program fixed cycle is checked the status signal of each incident symbol; in case the state of certain incident changes and just produces an incident, with the state of this incident, markers and corresponding incident symbol thereof be an incident sign (PointID), the system of composition such as the numeric type keyword of event group, event text, state text and seriousness grade thereof and the block that produces this incident, program page title, event signal title on duty/standby message, the time information such as target accuracy all store in the event queue.The variation remote signalling information of sending on the event information that produces and the needs is separated fully.
The external communication program of control protective device or system is checked through new events in the event queue; read above-mentioned all information of this incident and be sent to the SCADA system by the IEC60870-5-103 communications protocol of expanding; since in the standard IEC 60870-5-103 communications protocol for a processing delivery status and the markers thereof of SOE; therefore the IEC60870-5-103 communications protocol is expanded, so that above-mentioned all information of incident are sent on all.And define the special group number of a class for event information, and all event informations all adopt same entry number, therefore, need not be to the address of an IEC60870-5-103 of each event definition.
The SCADA system also imports to the content of the table of the PointGroup in the SQL Server database on the file server, EventText table, PointStatus table, EventSeverity table in the self database, and need not redefine.When the event message of event class group number is received based on same expansion IEC60870-5-103 communications protocol by the SCADA system, according to its event group, event text, the state text, the numeric type keyword of seriousness grade reads corresponding content of text and is inserted in the lump in the event table (complete sequence of events recording table) according to forming complete event text information other supplementary together with incident after the pre-defined rule processing from corresponding table, and upgrade bug list (incident symbol in this table, have and only have a record corresponding) with it, simultaneously warning class (according to the seriousness grade classification) incident is inserted into alarm meter.The remote signals that defines in the database of SCADA system is the remote signalling information that needs the routine of demonstration only, and the affair alarm signal is not needed to carry out any definition work.Simultaneously, control protective device or system get in the application software to be increased or the modification incident, and the SCADA system does not need to make any modification yet.
The event of failure (from bug list, reading the incident that the seriousness grade is the warning class) of the logout (reading) that human-computer interface system defines list of thing respectively, the tabulation of reporting to the police, error listing instant playback are complete, unacknowledged warning (from alarm meter, reading), current existence from event table.
