detailed description

The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

In the present invention, the smart grid dispatching control system basic platform (abbreviated as D5000 platform) and SCADA (Supervisory Control And Data Acquisition, Data Acquisition and Supervisory Control) systems are operating platforms and systems used by the State Grid. The control system on the control master station is the D5000 platform. The control operation anti-false check function of the present invention is a newly added application layer function on the basis of the D5000 platform, and belongs to the anti-false check service module of the D5000 platform. The main station system in Figure 2 refers to the D5000 platform, and the substation system refers to each substation system.

As shown in Fig. 1 and Fig. 2, a kind of anti-mistake inspection method of control operation based on the source end maintenance of the anti-mistake rules provided by the present invention is characterized in that it includes the following steps:

Step 1, the control master station obtains the equipment wiring diagram, model information and equipment point table files from the substation, and constructs the corresponding equipment model and the master-substation equipment comparison table;

The equipment includes circuit breakers, isolating switches, grounding knife switches, trolley switches, net gates and temporary grounding wires. The trolley switch model information is uploaded to the control master station through message mail; the control master station provides the primary factory station wiring diagram including the temporary ground wire/net gate/car switch position and the temporary ground wire/net gate/car switch model information provided by the substation , generate temporary ground wire/net door/car switch model data at the control master station;

The equipment point table file provided by the substation maintenance master station contains basic information such as equipment name and equipment ID. No., and the scheduling number of the equipment in the table on the substation side are maintained intact, and sent to the control master station through message mail; the control master station generates a master-substation equipment comparison table at the control master station according to the contents of the equipment point table that has been maintained in the substation. The name of the circuit breaker/isolating switch/grounding knife switch/temporary grounding wire/net gate/trolley switchgear of the master station and the scheduling of the circuit breaker/isolating switch/grounding knife switch/temporary grounding wire/net gate/trolley switchgear of the substation will be adjusted The numbers correspond one by one, and the five remote-proof signal point numbers of the temporary ground wire/net door/trolley switch/grounding switch/isolation switch/circuit breaker of the main station are updated;

Step 2, the control master station collects the real-time remote signal status of the temporary ground wire/net door/car switch from the substation microcomputer five-proof system;

The control master station is based on dispatching data network transmission, and uses the single-point remote signaling of the IEC60870-5-104 protocol to communicate with the microcomputer five-proof system of the substation. The single-point remote signal means that each information object occupies an information address; Temporary ground wire/net door/car switch status data; there are two collection methods, one is when the substation temporary ground wire/net door/car switch status changes, the substation microcomputer five-proof system actively uploads the temporary ground wire/network The door/car switch change status information, the other is to simultaneously control the main station timing general call temporary ground line/net door/car switch status information;

The control master station will also update the remote signaling status to the D5000 platform. First, the control master station interacts with the SCADA through the D5000 platform bus. After the SCADA realizes the remote signaling status processing of the temporary ground wire/net door/car switch, if there is status change information, it will update the status of the temporary ground wire/net door/car switch in sequence, and refresh the D5000 integrated graphical interface of the control master station in real time Temporary ground wire/net door/car switch status, and send displacement alarm information at the same time;

Step 3, the control master station obtains the anti-mistake logic rules in real time from the microcomputer five-prevention system of the substation, and establishes an expert knowledge base of safety anti-mistake rules;

The anti-mistake logic rules are uniformly maintained in the substation microcomputer five-prevention system; the control master station calls the anti-mistake logic rules in the substation to the control master station. The rules are sent to the control master station; the control master station intelligently analyzes and verifies the anti-mistake logic rules, that is, the control master station conducts and/or tree deduces the anti-mistake logic rules step by step until the final leaf node is generated; Whether the scheduling number corresponding to the leaf node exists in the master-substation equipment comparison table, if it exists, the verification is passed; if it does not exist, the verification is unqualified; after the verification is passed, it is automatically updated to the expert knowledge base of the control master station error prevention rules ; If the verification fails, the verification result will be fed back to the D5000 platform. For example, the logic formula verification is inconsistent, and the D5000 system will automatically generate alarm information and log files;

Step 4, the control master station performs an anti-mistake check on the remote control operation based on the anti-mistake rules.

Anti-error checking adopts anti-error rules and/or tree reasoning, and the specific reasoning process includes:

S401, using the error prevention rule as the root node, deduce the remote control operation step by step with and/or tree structure, mark the sequence and/or logical relationship of each node during the deduction process, until the final leaf node is generated;

S402, according to the master-substation equipment comparison table, determine the equipment corresponding to all nodes,

S403, according to the real-time remote signaling status of the device, use the reverse method to judge whether the root node obtained by judging each marked node and/or logical relationship is a solvable node;

S404. If the root node is a solvable node, it is considered that the device operation corresponding to the error prevention rule is allowed; otherwise, it is considered that the device operation corresponding to the error prevention rule is not allowed.

The control master station establishes the anti-error rule knowledge base by obtaining the anti-error logic rules from the substation microcomputer five-prevention system. When performing operation tickets, command tickets, rehearsals, and remote remote control operations, the operating equipment information is sent to the anti-error verification service module. According to the equipment identification and operation mode, the anti-mischeck service module deduces the five anti-error logic rules in the expert knowledge base of the anti-mistake rules that satisfy the equipment identification and operation mode, and judges whether the current operation meets the anti-mis-check; Check the operation, give the reason why the current operation is blocked, and display the result on the D5000 in a graphical interface. For the operation that meets the anti-mis-check, the air conditioning master station will send the control operation to the substation for execution.

The invention realizes the application of the main station of the five-prevention logic rules of the microcomputer five-prevention system of the substation, realizes the convenient expansion and modification of the anti-error rules, the maintenance workload is small, and the control of the master station's operation ticket, instruction ticket, rehearsal, remote remote control operation and anti-mistake check is improved. Safety and reliability, thereby effectively improving the stability of regional power grid operation.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. It should also be regarded as the protection scope of the present invention.
