Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The technical conception of the invention is as follows: and the visual display and verification functions of the anti-misoperation logic are realized by periodically reading the anti-misoperation logic rules in the real-time database and the remote signaling values of the operation objects in the logic operation part.

The method comprises the following steps: (1) the method comprises the steps of generating a rule base (2) shared by a total station monitoring background and a measurement and control device, providing a set of real-time database management system to provide rapid real-time data access (3), displaying five-prevention lockout logic on a visual graphical interface (4), verifying whether a certain equipment anti-misoperation lockout logic rule meets or does not meet in real time (5), simulating the condition that the equipment split-combination verification total station five-prevention logic rule meets or does not meet, and not changing the real-time database. The invention provides a method for checking five-prevention lockout logic in real time and in total station simulation, which improves the efficiency of checking and checking the anti-misoperation lockout logic rule, saves the debugging time of operators and ensures the correctness of the anti-misoperation lockout logic.

Example 1

The invention discloses a substation anti-error logic visualization method capable of real-time verification and simulation verification, which is shown in fig. 2 and comprises the following steps:

step one, unifying a rule base.

And configuring error locking prevention logic rules in a text form in a monitoring background, wherein the branch or combined operation of each device corresponds to one rule, the operation type 1 corresponds to the combined operation rule of the current device, and the operation type 0 corresponds to the current branch operation rule.

And generating a rule base shared by a monitoring background and a measurement and control device (device for acquiring the state of the equipment) of the total station, wherein all equipment (circuit breakers and disconnecting links) participating in error prevention in the transformer substation acquire corresponding error-prevention locking logic rules from the rule base, so that the consistent effectiveness of the error-prevention rules of the total station is ensured. The rule base adopts files with uniform format, and the monitoring background and the measurement and control device use the rule files to perform anti-error logic judgment.

Rule contents and formats as shown in fig. 4, taking rule 1 and rule 2 as examples, the device name "the 61850 model signal and control switch 1 of NS 3670" represents the operation rule configured for the device, the interval name represents the location of the device, the operation type 1 represents the combined operation of the device, 0 represents the divided operation of the device, the condition number is the number of the following conditions, (1) (2) is the condition, the measurement point is the description of other devices, such as (1) represents, the 61850 model with the name NS3670 is disconnected 2, the measurement point name can be repeated, ns3670.CTRL/QGCSWI2.pos. stval represents that the interval name is NS3670, CTRL represents that the device can be remotely controlled, QGCSWI2 is the identification of the device, and is unique and unrepeatable within the interval of NS3670. "equal to point" means that the equipment state described by the measuring point (1) is equal to point, and the condition (1) can be met. Rule 1 concludes that if the 61850 model signal of the device NS3670 is to be combined with the control switch 1, the device states described in conditions (1) and (2) must first be satisfied; rule 2 is similar.

One device can have a plurality of combined (separated) operation rules, wherein both the rule 1 and the rule 2 are combined operation rules of a 61850 model signal of the device NS3670 and a control knife switch 1, and the two rules are in an OR relationship, and before the device is subjected to combined operation, the device can be verified to pass by meeting at least one of the rule 1 and the rule 2.
