Intelligent substation electrical secondary system adopts digital sample values to replace conventional simulation of ac to transmit; the GOOSE switching value that protection outlet, control and signal circuit are also changed into based on fiber optic Ethernet by conventional secondary cable is transmitted to realize, and has avoided the blind spot that conventional substation electrical secondary system on-line monitoring exists.Digitizing technique is laid a good foundation for realizing secondary device on-line monitoring system.
The secondary device of intelligent station itself has possessed part self-checking function at present, as the self check of input and output hardware-in-the-loop, the self check of control loop broken string etc., but monitoring information is comprehensive, monitoring range is fewer, some important equipment are not brought monitoring range into as process layer switch, cannot really realize the repair based on condition of component of electrical secondary system.
New Generation of Intelligent transformer station has proposed the specification requirement to secondary device on-line monitoring simultaneously: the running status of the equipment such as monitoring and protection devices type, measure and control device, fault wave recording device, the territory protective device of standing, monitoring host computer, data communication gateway machine, data server; the Condition Monitoring Data of harvester; realize overview display and the alarm of secondary device running state information, but also there is no feasible secondary device state on_line monitoring method at present.
Summary of the invention
The object of this invention is to provide a kind of feasible secondary device state on_line monitoring method, to realize the on-line monitoring to secondary device state, reduce or cancel the periodical inspection of electrical secondary system, check, increase work efficiency, the unnecessary loss of avoiding equipment to stop transport and bring.
For achieving the above object, secondary device state on_line monitoring method of the present invention is for intelligent substation safe I district and safe II district, and the step of method is as follows:
(1) gather the Monitoring Data that needs of safe I district internal procedure floor, wall;
(2) safe I district internal procedure floor need Monitoring Data to deliver to bay level IED to process after with the Monitoring Data that needs of wall, be uploaded to together monitoring host computer;
(3) the self check information of the data server of station level, data network management machine is passed to monitoring host computer, and monitoring host computer gathers the self check information of self;
(4) the integrated application server in safe II district regularly reads and shows that in real time comprise process layer, the wall in safe I district need the secondary device information of the self check information of monitoring information and station level equipment.
The safe I of described step (1) district internal procedure floor, wall need Monitoring Data comprise transducer Information Monitoring, running state information, warning information and to time information.
In described step (3), self check information comprises computer CPU, working temperature, CPU usage, memory usage and disk utilization rate information.
The secondary device information that the middle integrated application server of described step (4) regularly reads safe I district refers to: the monitoring host computer in safe I district sends handshake information to integrated application server, receive and shake hands after acknowledge message, the information sending according to integrated application server, regularly detects information and is sent to aggregation of data application server.
Secondary device state on_line monitoring method of the present invention, can to the self check information of intelligent substation station level, process layer, all secondary devices of wall, running state information, warning information, to time the information such as information monitor, realize overview display and the alarm of secondary device; For boosting productivity, human cost is stopped transport, saved to minimizing equipment, and reducing or cancelling provides technical support to the periodical inspection of electrical secondary system, check.

Embodiment
Secondary device state on_line monitoring method is for intelligent substation safe I district and safe II district, and the step of method is as follows:
(1) gather the Monitoring Data that needs of safe I district internal procedure floor, wall;
(2) safe I district internal procedure floor need Monitoring Data to deliver to bay level IED to process after with the Monitoring Data that needs of wall, be uploaded to together monitoring host computer;
(3) the self check information of the data server of station level, data network management machine is passed to monitoring host computer, and monitoring host computer gathers the self check information of self;
(4) the integrated application server in safe II district regularly reads and shows that in real time comprise process layer, the wall in safe I district need the secondary device information of the self check information of monitoring information and station level equipment.
The present invention is based on state net New Generation of Intelligent substation secondary device on-line monitoring technique requirement ,Dui state net intelligent substation supervisory control system as shown in Figure 1.
The main secondary device online data monitoring in this secondary device state on_line monitoring method:
This secondary device state on_line monitoring data are mainly in safe I district and safe II district:
Safe I district: data are responsible for gathering and conversion by electric current and the voltage transformer of process layer, through merge cells, synchronously process, other analog quantitys or quantity of state data are by the intelligent terminal of hard contact access procedure layer, delivering to bay level IED processes, again by delivering to station level monitoring host computer on IED, monitoring host computer by analysis, process and unified displaying, data deposit data server in the most at last.
