1 Intelligent station Soft Press plate advanced applications
The soft pressing plate of the secondary equipment of the intelligent substation can be divided into a functional soft pressing plate, an outlet soft pressing plate and an interface soft pressing plate according to functions. Compared with a conventional transformer substation, the intelligent station is additionally provided with the soft receiving pressing plate, the soft receiving pressing plate is divided into a GOOSE receiving soft pressing plate and an SV receiving soft pressing plate, and the soft pressing plate determines whether secondary equipment of the intelligent station can correctly process GOOSE information and SV information.
Through the graphical processing and the regular automatic inspection of soft clamp plate to soft clamp plate, fortune dimension personnel can in time master in the intelligent substation protection device's soft clamp plate in a comprehensive way and throw the circumstances of moving back, through with the contrast analysis of actual operation condition, can in time accurately discover the soft clamp plate mistake throw, the mistake moves back the circumstances, and then in time accomplish the maintenance operation, improve intelligent substation fortune dimension efficiency.
1.1 standardized design
The soft pressing plates are named and defined according to standard rules, and are unified in a whole station, so that misoperation caused by understanding errors of operators due to different naming modes of the similar soft pressing plates is avoided.
All the interval pictures are arranged according to a unified standard, the functional soft pressing plates are distinguished by yellow marks and the outlet soft pressing plates are distinguished by red icons, the soft pressing plates which are easy to be confused are marked specially, and explanation is carried out in a special area beside the soft pressing plate area. In view of the fact that the management of the soft pressing plate of the intelligent station relates to a plurality of units such as regulation, operation, maintenance and construction units, operation and maintenance areas of the soft pressing plate operated by monitoring personnel and soft pressing plate operated by maintenance personnel are strictly and clearly divided in each interval picture in the achievement technology, the operation personnel and the maintenance personnel have soft pressing plate operation authorities corresponding to the post responsibilities of the operation personnel and the maintenance personnel, and the operation personnel and the maintenance personnel respectively perform their duties in the work without worrying about leakage.
And a single soft pressing plate is set to explain the retrieval function, and the information of the soft pressing plate can be retrieved by the position of the mouse stopping soft pressing plate, wherein the information comprises the name of a background machine, the name in the device, function description, a function schematic diagram, the on-off state of a normal operation mode and the like.
1.2 Intelligent alarm for abnormal on/off of soft pressing plate
Before the relay protection equipment is put into operation (before new equipment of a protection infrastructure project is put into operation, before new equipment is put into operation after technical change and replacement, before double differential equipment is upgraded and accepted for operation, before commissioning equipment is accepted and accepted for operation, and the like), protection specialists of each unit review and approve the soft pressing plate function description and the normal operation mode commissioning state of all devices of a transformer substation controlled by the unit. Special attention is paid to examination of the switching state and the functional description of the soft pressing plate which is easy to make mistakes and causes abnormal protection action behaviors, such as a reclosing soft pressing plate, a communication three-jump soft pressing plate and the like. The functional description of the soft pressing plate and the examination and approval flow chart of the normal operation mode switching state diagram are shown in fig. 1, and the division of labor of an operation and maintenance unit and a maintenance unit is clear, and specifically comprises the following steps:
1) inputting the name of the soft pressing plate consistent with the field, and noting the soft pressing plate needing special explanation;
2) submitting functional descriptions of all the soft pressing plates, and performing key description on the soft pressing plates which are easy to make mistakes;
3) rechecking whether the soft pressing plate information is complete and accurate, and if so, entering the next step; otherwise, returning to the step 2);
4) writing a normal soft pressing plate on-off state diagram, and rechecking whether the normal soft pressing plate is correctly turned on or off; if yes, entering the next step; otherwise, returning to the step 3);
5) checking whether the soft pressing plate description graph is qualified or not, and if so, finishing the checking; otherwise, return to step 2). The soft pressing plate description diagram comprises a soft pressing plate function description and a soft pressing plate normal operation mode switching state.
And recording the functional description and the switching state of the normal operation mode of the soft pressing plate after the approval of the audit into a background monitoring system. And the total station soft pressing plate is automatically inspected at regular time or manually inspected, and is compared with the on-off state of the normal operation mode approved by the audit, and if the total station soft pressing plate is different from the defined normal state, an alarm window is popped up to prompt which soft pressing plates are in abnormal states. For the device in the maintenance state, the device does not participate in the one-key patrol alarm function after the maintenance board is hung.
2 sequential control of protection device
In the intelligent substation, the operation equipment and the equipment to be overhauled are connected through a network, and in view of a hard-wired connection mode different from that of a traditional substation, the operation equipment and the equipment to be overhauled are difficult to be physically isolated on the premise of not damaging a network structure of the intelligent substation. Safety measure isolation can be performed only by changing the states and sampling of the intelligent device sender and receiver, which puts higher requirements on operation and maintenance personnel and increases the possibility of errors in safety measure implementation in the operation and maintenance process. The method provides a 'one-key' sequential control operation, and realizes that the soft pressing plates such as a soft pressing plate sending, a soft pressing plate receiving and a functional soft pressing plate are automatically executed in sequence by a protection device according to preset steps. Therefore, the one-key type sequential control can realize the sequential control of equipment throwing and stopping and the sequential control of secondary safety measures. The one-key safety measure sequence control reduces the risk of accidents in the operation and maintenance process by examining, approving and solidifying the safety measure implementation process through experts and then carrying out sequence control.
Firstly, according to the regulation requirements, making a secondary safety measure execution flow; then, the safety measures are approved and solidified by experts; and finally, automatically completing a series of soft pressing plate switching operations according to rules by a single operation command of the background monitoring system according to the predefined operation logic and rules, and finally changing the running state of the relay protection device, thereby realizing one-click execution of safety measures. The soft pressing plate sequence control function can continuously adopt the working mode of a typical operation ticket. When the sequence control is executed to operate a certain soft pressing plate, the picture where the soft pressing plate is located is automatically called so as to display the throwing and retreating states before and after the operation. In particular to an operation ticket of a plurality of protection devices, and the picture of each device is required to be called normally.
The sequence control can help operators to execute complex operation tasks, traditional operation tickets are converted into task tickets, complex operation is completed in one key, operation efficiency can be greatly improved, risks of misoperation are reduced, manual operation time is shortened, and the effect is particularly obvious in large-scale high-voltage intelligent substations.
3 reconstruction and expansion without power cut
3.1 reconstruction and expansion technical scheme without power outage
When the intelligent substation is reconstructed and expanded, the bus protection (taking the 220kV double-bus wiring condition as an example) needs to be configured and installed, so that the line protection of other commissioning intervals is forced to carry out verification work, the workload, complexity and difficulty are increased, meanwhile, the safety risk of related work is further increased, the reconstruction and expansion work of the intelligent substation is more difficult than that of a conventional station, and the 'total station power failure' has to be arranged to be matched with the reconstruction and expansion work, so that the production operation is influenced.
When reconstruction and extension are carried out, the technical scheme for avoiding unnecessary bus protection downloading and expanding range verification is as follows:
(1) the substation system configuration (SCD configuration) at the time of new station construction is considered at all line intervals in the future. For the intelligent devices (line protection, intelligent terminals and merging units) with no line interval selected yet, a concept of 'stand-by device' is provided, any intelligent device meeting the requirements is set as the 'stand-by device', only the GOOSE and SV services sent to bus protection by the line protection, the intelligent terminals and the merging units are needed to be configured, and other services are not needed to be configured for the time. The debugging work of the newly built station also comprises debugging and verification of the communication between the substitute device and the bus protection.
(2) The bus protection should have the whole soft clamp plate that throws back of interval. Before the new station is put into operation, the whole switching soft pressing plates at intervals of all the unestablished lines are set to be in a switching-out state, the intervals are regarded as nonexistent by bus protection, and do not participate in operation and alarm.
(3) When the system configuration of the reconstruction and extension project is developed, the new device replaces the substitute device in the original position, namely, the substitute device uses the IED name, the MAC address, the control block name of the configured service, the application identifier and the like, and configures various services, but the description attribute of the IED can be changed. In the debugging and later stages, the whole throw-in and retreat soft pressing plate (on the bus protection) corresponding to the new upper interval is set to be in an throw-in state.
3.2 modeling based on IEC61850
The spare interval modeling model is formed as shown in fig. 2, and the specific implementation method is as follows:
step 1: logical node partitioning
Firstly, defining specific functions required by the line protection, the intelligent terminal and the merging unit stand-in device, then determining which functions of the stand-in device need to exchange data with other intelligent devices, and then decomposing each function needing data exchange into Logical Nodes (LN).
In order to avoid downloading the bus protection after reconstruction and extension, the data set of the intelligent device sending GOOSE and SV information to the bus protection needs to be fixed, including the name of the data set, the sequence and the number of the members of the data set. For example, the GOOSE data set for the fixed line protection circuit to send to the bus protection is shown in table 1.
TABLE 1 GOOSE line protection dataset
Step 2: building logical devices
And after the functions of the stand-in device are determined, a logic equipment model is established for the stand-in device to realize communication among a plurality of logic nodes. The logic device merges a plurality of logic nodes and related services (such as GOOSE and SV services). A logical device generally includes three logical nodes: a logical physical device (LPHD) representing device information and health status; a logical node 0(LLN0) providing GOOSE control blocks, SV control blocks, etc. communication services; n Logical Nodes (LN) containing specific functions.
Step 3: establishing a server model
Modeling the substitute device into a server model, and directly replacing the substitute device with a new device in the later reconstruction and extension process. According to the IEC61850 standard, the Server model can adopt a P2P (publish-subscribe) mode or a Client-Server (Client-Server) mode, thereby completing reliable transmission of GOOSE information and SV information between intelligent devices.
The power failure hours in the long-term reconstruction and extension process are reduced through the uninterrupted reconstruction and extension strategy, and meanwhile, repeated test verification of other commissioning intervals is avoided, so that the workload and the operation and maintenance complexity are reduced, and a theoretical basis is laid for the implementation of the next uninterrupted reconstruction and extension work.
4 visual display of secondary virtual circuit
The secondary virtual circuit visual display graph preferably meets the following requirements:
1) the method takes a protection device as a core, and clearly displays the connection condition of switch position signals, soft pressing plates and other virtual terminals of the protection device and other devices.
2) The soft pressing plate graph is shown on the corresponding virtual terminal connecting line, and the on-off state of the soft pressing plate is visually represented by different graphs.
3) The figure should clarify the sender and receiver of the virtual terminal connection.
4) The maintenance pressure plate graphs of all the equipment in the drawing are marked in the equipment frame, and the on-off state of the maintenance pressure plate is visually represented by different graphs.
When the state of the pressing plate changes, the virtual circuit is automatically popped up, and the state of the pressing plate automatically flickers. When the protection switching order control is executed to operate a certain soft pressing plate, the picture of the device is automatically called so as to display the switching state before and after the operation in real time. When the secondary safety measures are carried out in sequence control to operate a certain soft pressing plate, the picture of the device is automatically called to display the throwing and retreating states before and after the operation of the device in real time, after the operation is successful, the pressing plate is marked with a special mark (obvious marks such as framing, thickening and the like can be adopted), and other persons without permission cannot operate the device.
5 automatic calling intelligent comparison of secondary virtual loop and abnormal connection pushing alarm

The method 2 comprises the following steps: and (3) exporting files such as CID, CCD and the like of the total station IED device from the SCD file approved by the relay protection special worker by using a corresponding configuration tool, respectively comparing the files with the files such as CID, CCD and the like called from the IED device in real time, immediately popping a window to alarm which loops are configured wrongly once inconsistency is found, and marking red flashing visual display on a secondary virtual loop visual display schematic diagram.
In order to enhance the process trace management, all secondary virtual loop comparisons (automatic timing comparison and manual trigger comparison) must have comparison records, including information such as comparison time, comparison personnel, comparison results and the like, which should be stored and screened and inquired according to keywords.
And 6, remotely uploading the information of the pressing plate.
All pressure plates of the transformer substation and abnormal alarm information for virtual circuit comparison are transmitted to a master station through a scheduling data network, a protection professional can monitor the condition of switching on and off the pressure plates of all intelligent station protection devices of the unit, the condition of monitoring secondary circuit configuration connection and the condition of executing secondary safety measures without leaving home, after the opportunity is mature, the operation and regulation personnel can directly realize the control of the same operation interface with a background machine from the master station, after the authority is set, the operation and regulation personnel can carry out remote control, and the remote control of the pressure plates can be realized by the same operation as the background machine operated on site.

Through the realization of the function of alarming the abnormal switching of the soft pressing plate, the problem of abnormal switching of the soft pressing plate can be found in a short time, and the automatic operation level and the operation and maintenance efficiency of the transformer substation are improved.
