Description
Technical Field
The invention belongs to the technical field of intelligent substations, and particularly relates to an automatic configuration method for monitoring pictures of secondary equipment of an intelligent substation.
Background
The IEC 61850 standard is a foundation for intelligent substation construction, and the 61850 series standard adopts an equipment-oriented object modeling technology and adapts to the requirement and development of application functions through model self-description. At present, domestic secondary equipment modeling does not fully reflect the self-description characteristics of the model, and 61850 is used as a universal communication protocol. The secondary device LN definition largely uses general process I/O logical nodes GGIO, resulting in that the physical meaning of the signal cannot be understood from the perspective of the model, such as: remote signaling information of the positions of a switch and a disconnecting link in the protection device model is carried in GGIO, and standard XCBR and XSWI are not adopted.
On the other hand, 61850 defines a total station system specification description SSD (system specification description) file, describes a primary system structure and a secondary device association relationship, and is actually a file which is left up, and the association relationship between the secondary devices can be indirectly obtained through the primary and secondary device association relationship, but in the current intelligent substation integration process, the secondary device LN is not basically associated in the SSD file, and the SSD file is not configured at all.
On the basis of the existing secondary equipment modeling, when a secondary equipment monitoring screen is configured, signals such as telemetering and remote signaling of each secondary equipment must directly face an instantiated specific device model, a single interval information association configuration work result cannot be reused, the information configuration efficiency is low, the configuration accuracy is difficult to guarantee, and once a certain equipment model changes, the relevant configuration work needs to be completed again.
Disclosure of Invention
The invention aims to provide an automatic configuration method for a monitoring picture of secondary equipment of an intelligent substation, which can overcome the problems that in the prior art, when a monitoring picture of the secondary equipment is configured, signals such as remote measurement and remote signaling of each secondary equipment are required to directly face an instantiated specific device model, the work result of single-interval information association configuration cannot be reused, the information configuration efficiency is low, the configuration accuracy is difficult to ensure, and the configuration work efficiency and quality of the monitoring picture of the secondary equipment of the intelligent substation can be obviously improved.
In order to achieve the above purpose, the solution of the invention is:
an automatic configuration method for monitoring pictures of secondary equipment of an intelligent substation comprises the following steps:
step 1, establishing a corresponding relation between a standard LN and each secondary equipment LN instance by associating each interval secondary equipment CID file to a corresponding interval in an SSD;
and 2, configuring secondary equipment monitoring picture templates at intervals, and automatically finishing correlation of each telemetering, remote signaling and signal variable in the monitoring picture based on the corresponding relation between the standard LN and each interval secondary equipment LN instance.
The method is based on semantic modeling of the secondary equipment and description of each interval association standard interval name and standard Logical Node (LN) in the SSD file by system specification, and the corresponding relation between the standard LN and each interval secondary equipment LN instance is automatically established. By instantiating the secondary equipment monitoring picture templates one by one according to intervals, signal variables such as telemetering signals, remote signaling signals and the like in the automatic monitoring picture can be automatically associated.

Detailed Description

The invention provides an automatic configuration method for monitoring pictures of secondary equipment of an intelligent substation, wherein the secondary equipment is modeled according to meanings, a secondary equipment system describes standard interval names and standard LNs which are associated with intervals in an SSD file in a standard manner, and the corresponding relation between the standard LNs and the instances of the secondary equipment LNs is established by associating CID files of the secondary equipment in the intervals to the corresponding intervals in the SSD. And configuring a secondary equipment monitoring picture template according to intervals, and automatically finishing association of signal variables such as each telemetering signal, each remote signal and the like in the monitoring picture based on the corresponding relation between the standard LN and each interval secondary equipment LN instance.
The implementation steps of the invention are as follows:
and step 47, replacing the secondary equipment standard LN in the single-interval secondary equipment monitoring picture template with the LN instance corresponding to each interval secondary equipment, replacing the secondary equipment standard LN in the cross-interval secondary equipment monitoring picture template with the LN instance corresponding to the cross-interval secondary equipment, and completing automatic association of signal variables such as each telemetering signal, each telecommand signal and the like in the monitoring picture based on the corresponding relation between the standard LN and each interval secondary equipment LN instance. Taking a line interval 3 as an example and taking a branch 3 as an example, the phase A position signal lamp is associated with a standard logic node A.XCBR, and the reference name of a first set of line protection instance signals is PL2203A/A-XCBR1.Pos.stVal; the state of a line differential protection soft pressure plate is associated with a standard logic node PDIF, and the reference name of an instance signal is PL2203A/PDIF1. EnaTrp.stVal; the protection measured value is associated with a standard logic node MMXU, and the reference name of an A-phase current instance signal is PL2203A/MMXU1.A. PhSA. CVal. Mag. F; the protection phase A trip optical word board is associated with a standard logic node PTRC, and the example signal is referred to as PL2203A/PTRC1.TR. PhsA.
When a certain secondary equipment model changes, the updating work of the picture configuration can be completed only by re-executing the step 45 to refresh the corresponding relation between the standard LN and the secondary equipment LN instance and executing the step 47 to refresh the secondary equipment monitoring picture related to the equipment.
