The invention relates to a synchronous access method of realtime banks and a transformer substation monitoring system. The system comprises a master server and a slave server, wherein operator stations are respectively in communicating connection with the master server and the slave server; the master server and the slave server are respectively provided with the realitime bank, a server side application module, a client side application module and a server side realtime bank remote access interface module; synchronized private network connection is adopted between the master server and the slave server so as to be used for synchronization of the two realtime banks; each operator station is provided with a client side application module and a client side realtime bank remote access interface module; and the operator stations access the realtime banks in the servers through the client side realtime bank remote access interface modules and the server side realtime bank remote access interface modules. According to the system, a client side realtime bank remote access mechanism is arranged, so that the synchronization of the servers to operators is omitted, the synchronization of the realtime banks can be realized only through the synchronization between two host machines, the synchronization of the two servers can be separated by adopting a private network, the network of the monitoring system is not affected, the reliability is enhanced, and the efficiency is improved.
Description
Technical field
The invention belongs to the power system automation technology field, relate to a kind of real-time storehouse synchronous access method and monitoring system of electric substation.
Background technology
Along with the propelling that intelligent grid is built, supervisory control system is increasingly high to the reliability requirement of real time data, and this just has higher requirement to the time of active and standby switching.
Pattern is under two server multioperation person stands configuration at present; Operator station and server all dispose real-time storehouse; Real time data need be synchronized to fully in server and each operator station from master server, also causes the station level network traffic data bigger during synchrodata amount Datong District in real time.
When active and standby switching, new master server be equipped with server and each operator and all will carry out once in real time the storehouse and recover, storehouse restore data amount is big in real time, causes network traffics very big.Because in real time to recover host number many in the storehouse, storehouse recovery time long (under the configuration of two server dual operation station) in real time usually above 1 minute, this causes the active and standby switching recovery time can not be up to standard.
Summary of the invention
The purpose of this invention is to provide a kind of real-time storehouse synchronous access method and monitoring system of electric substation, to solve the problem that the synchrodata amount is big, offered load is heavy that original real-time storehouse method for synchronous causes.
For realizing above-mentioned purpose; The synchronous access method technical scheme in real-time storehouse of the present invention is following: adopt the active/standby server of the monitoring system of electric substation of this method to adopt synchronous private network to connect; Operator station is connected with the real-time storehouse of active/standby server through distant place access interface; Operator station no longer disposes real-time storehouse, and real-time storehouse only is set in active/standby server;
When the real-time storehouse of client-access in the operator station:
Through dynamic load power system operation object accesses module I CSTaskObjects, call common object accesses interface and carry out the visit of real-time storehouse, the operation of thread is write in shielding to real-time banked cache when application program is client application;
Carry out common real-time storehouse visit through sharing real-time storehouse type identification access modules ICSTypeInfo class libraries, load the remote interface module;
Through the real-time storehouse of dynamic load general operation object accesses module I CSDBObjects module, call common object accesses interface and carry out the visit of real-time storehouse;
When service end is visited real-time storehouse:
The cache object access interface of service end visit ICSTaskObjects module;
Service end is directly visited real-time bank interface.
Further, said ICSTypeInfo module selects to load real-time storehouse access modules according to the application name that is loaded, if client then loads the remote interface module, otherwise loads the local interface module.
The synchronous monitoring system of electric substation in real-time storehouse of the present invention comprises active/standby server; Operator station is connected with the active/standby server communication respectively; Real-time storehouse, service end application module, client application module and the real-time storehouse of service end remote access interface module all are set in the said active/standby server; And adopt synchronous private network to connect between the active/standby server and be used for the synchronous of two real-time storehouses; Client application module and the real-time storehouse of client remote access interface module all are set in the operator station, and operator station is through the real-time storehouse in the real-time storehouse of client remote access interface module and the real-time storehouse of the service end remote access interface module accesses server.
Access method and monitoring system of electric substation that real-time storehouse of the present invention is synchronous; Had the real-time storehouse remote access of client mechanism then saved server to the operator synchronously; For real-time storehouse have only synchronously between two main frames synchronously; Can the synchronous employing private network of two-server be separated like this; Can solve through this real-time storehouse method for synchronous that the synchrodata amount that original real-time storehouse method for synchronous causes is big, offered load heavily waits shortcoming, reduce the station level network traffics, improve the real-time storehouse synchronous efficiency in the supervisory control system; The real-time storehouse of monitoring system of electric substation relates to station level main frames such as active/standby server, operator station, engineer station; This method for synchronous need be provided with real-time storehouse and real-time storehouse remote access interface module in active/standby server; The real-time storehouse of adopting dedicated Internet access to be used between active/standby server between the active/standby server simultaneously is synchronous; But not in the independent real-time storehouse of configuration but connect the real-time storehouse of main frame through remote access interface, the remote access interface of operator station can be connected to the real-time storehouse of new main frame when active and standby the switching taken place, thereby realizes the operator station Refresh Data in operator station; It is synchronous to operator's real-time storehouse so just to have cancelled server; For real-time storehouse, full station have only between two main frames synchronously, can with the synchronous employing private network of two-server separately not influence the supervisory control system network; Reliability strengthens, and efficient improves.
