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.
A sequential control operation order non-power-off checking method comprises a sequential control host side method and a plant station simulation side method; wherein the content of the first and second substances,
the method for the forward control host side comprises the following steps:
step 1) executing the instruction of each link of the operation task corresponding to the sequential control operation order to be checked, and sending the instruction of each link to execute the corresponding remote control instruction to the plant station simulation side.
The specific process is as follows:
11) and generating a corresponding operation task according to the sequence control operation order to be checked.

the instruction execution comprises starting instruction execution, checking operation conditions, checking current equipment state before execution, judging a sequence control locking signal, judging total station accident, judging conditions before single step execution, checking built-in anti-misoperation locking of a single step sequence control host, performing anti-misoperation checking of a single step intelligent anti-misoperation host, issuing a single step operation instruction and judging single step confirmation conditions.
And step 2) responding to the received plant station simulation side feedback remote control instruction to be successfully executed, and checking the sequence control operation order to pass.
The plant simulation side method is characterized in that a simulation system is generally adopted for simulation, namely the simulation system side method comprises the following steps:
s1) emulating a plant station in communication with the front control host side.
Simulating the plant station according to the SCD or the device configuration text to replace an actual physical device to communicate with the sequence control host; importing the checked sequence control operation order as a basis for judging whether the sequence control operation order on the sequence control host is correct or not; and initializing a database of the simulation plant station to ensure that the section of the database of the simulation plant station is consistent with the section of the current plant station real-time database of the sequence control host.
S2) responding to the received remote control command sent by the front control host side, the simulation station executes the remote control command and feeds back the remote control command execution result.
And (3) executing a remote control command: and comparing the remote control command with the corresponding operation item of the imported sequence control operation order, judging whether the remote control point number and the remote control on-off type are matched, if so, checking the operation item successfully, changing the remote signaling state corresponding to the switch disconnecting link, and feeding back the remote control command to be successfully executed.
As shown in fig. 1 and 2, the sequential control operation order non-stop power-supply checking method is combined with a manual operation process, and specifically includes the following steps:
1) and using a sequence control operation order editing tool to make a sequence control operation order.
The sequential control operation order is created by taking an interval as an object, a plurality of sequential control operation orders can be created in one interval, and each sequential control operation order needs to specify information such as a source equipment state, a target equipment state, an operation task name, a sequential control locking signal and the like.
And adding an operation item list for each sequence control operation ticket, and setting information such as an operation object, a condition before execution, a confirmation condition and the like of each operation item.
And storing the sequence control operation order into a database, wherein the type of the stored operation order is not checked.
And after the sequential control operation order editing tool opens the checked operation order and modifies and stores the operation order, the type of the operation order is changed from checked to unchecked.
2) The simulation system initializes the simulation plant station.
3) And calling the uncorrected operation order by using the sequence control operation order editing tool to perform manual correction, and then starting a one-key sequence control program in the sequence control host to interact with the simulation system.
And the left side of the sequence control operation order editing tool displays the transformer substation, the voltage grade, the interval and the sequence control operation order in a tree list mode according to the hierarchy.
After clicking a sequence control operation ticket on the tree list, displaying the content on the right side for the checking of operators (namely manual checking), wherein the displayed content comprises operation task information (operation ticket name, current state, target state and version information), operation item information and locking signal information. Clicking uncorrected operation order nodes on the sequence control operation order editing tool tree list by a right key, popping up a menu, selecting a 'checking' menu item, starting a one-key sequence control program, and starting a one-key sequence control operation process after permission verification is passed, namely generating tasks, simulating rehearsal and executing instructions. When the checked operation tickets are displayed on the tree-shaped list during manual checking, the font color is set to be dark green, and the operation tickets are obviously distinguished from the operation tickets which are not checked.
The contents of the different types of operation item displays during manual checking are shown in table 1.
TABLE 1
And the one-key sequence control program calls the operation order selected by the sequence control operation order editing tool from the database, automatically generates an operation task, starts simulating rehearsal, and starts executing instructions after the simulation rehearsal of all links is successful. When the instruction is executed, the sequence control host sends a remote control instruction to the simulation system. After receiving the remote control instruction, the simulation system compares the remote control instruction with the corresponding operation item of the imported sequence control operation order, judges whether the remote control point number and the remote control on-off type are correct, if the received remote control instruction is not matched with the current operation item of the current operation order, returns a checking error prompt message, and stops checking by the sequence control host; if the remote control execution result is matched with the remote control execution result, the operation item of the step is successfully checked, the simulation system changes the remote signaling state corresponding to the switch disconnecting link and sends the remote signaling state to the sequence control host, and the remote control execution success result is returned.
The simulation system generates an event record after receiving the remote control instruction, records the execution start time, the execution end time, the operation time of each step, the operation content, the check result and other information of the one-key sequential control instruction, and provides a basis for checking the historical retrospection of the operation ticket. The event record provides inquiry, printing and export functions, and cannot be deleted or modified.
After the instruction is executed, analog quantities such as current and voltage are set on the simulation system through manual counting, and the analog quantities are uploaded to the sequence control host, so that the current and voltage judgment condition in the switch confirmation condition is met, or the current and voltage judgment condition is selected to be ignored after manual confirmation when the current and voltage do not meet the confirmation condition.
And when the sequence control operation order is checked, a principle of double-set anti-error mechanism checking is adopted, one set is an anti-error logic lock built in the sequence control host, and the other set is anti-error logic check of the independent intelligent anti-error host. The intelligent anti-misoperation host acquires the current state of the switch disconnecting link from the sequential control host. Simulating preview and instruction execution, simultaneously performing built-in anti-misoperation logic locking check and independent intelligent anti-misoperation logic check of the sequence control host, terminating operation if the built-in anti-misoperation logic locking check fails, popping up a prompt error, and lighting a built-in anti-misoperation locking indicator lamp; and if the error-proof logic check of the independent intelligent error-proof host fails, the operation is suspended, an error is prompted, an intelligent error-proof check indicating lamp is lightened, whether the error prompt of the error-proof check failure of the single-step intelligent error-proof host is ignored or not can be selected, the error prompt needs to be checked by permission during the neglect, and the check operation can be continued after the check is passed.
4) And after the sequence control operation order passes the checking, storing the sequence control operation order as a checked operation order.
And after the checking is successful, the sequence control operation ticket is stored as a checked ticket, and the information of the checking state, the checking time, the checking person and the like of the operation ticket is recorded in the database. And updating the display state of the operation ticket on the sequence control operation ticket editing tool tree list to show that the operation ticket passes the check. If the checking fails, the sequential control operation order type is still not checked.
5) Judging the checking state of the operation order when calling the sequence control operation order by one-key sequence control
When one-key sequential control is carried out, if the sequential control operation order called from the database is an uncorrected operation order, the calling is forbidden, and only the checked operation order can be called.
The method simulates the plant station, replaces the communication between an actual physical device and the sequence control host, overcomes the defect that part of power failure must be carried out in turn in the existing sequence control operation order checking scheme, the checking process is completely consistent with the one-key sequence control actual operation process, is convenient and quick to implement, solves the problems that the traditional checking mode does not have the condition of power failure ticket checking and the checking period is too long, shortens the sequence control operation order checking period, improves the operation and maintenance work efficiency of the transformer substation, deepens the application of the one-key sequence control technology, and ensures the safe and efficient operation of the power grid.
