The invention relates to the field of substations, in particular to a method and a system for acceptance of built-in programs in intelligent substations.

Background technique

In the current power system, it is a common method to load programs on the substation integrated self-system and digital substation. Through the electrical operation programming, the operator can select a programmed operation command according to the operation requirements. The selection and execution of the operation ticket and the verification of the operation process are automatically completed by the substation operating system, realizing "one-key operation". In the process of programmatic operation, each step must satisfy the corresponding execution condition before execution, so that the execution of the operation step is allowed. If the execution condition is not satisfied, the execution of the operation step is prohibited.

Detailed ways

In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the related drawings. Preferred embodiments of the present application are shown in the accompanying drawings. However, the application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used herein in the specification of the application are for the purpose of describing specific embodiments only, and are not intended to limit the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in FIG. 1 , in order to improve the reliability and stability of the programmed operation, ensure that the programmed operation process can be interrupted normally in the event of a fault or abnormality, and reduce the risk of misoperation, an embodiment of the present application provides a built-in smart substation A method of acceptance of a program, the method comprising:

S1: perform sequential control debugging on the built-in program of the intelligent substation to be tested, and execute S2 when the built-in program passes the sequential control debugging;

S2: perform a destructive test on the built-in program and obtain the test result;

S3: Determine the acceptance result of the built-in program according to the test result.

In one embodiment, the S1: perform sequential control debugging on the built-in program of the intelligent substation to be tested, and execute S2 when the built-in program passes the sequential control debugging.

Wherein, the sequential control debugging is a process of debugging using corresponding operation tickets according to the initial state and preset target state of the intelligent substation to be tested.

Specifically, according to the initial state and the preset target state of the smart substation to be tested, use the corresponding operation ticket to debug the built-in program of the smart substation to be tested, and if the built-in program of the smart substation to be tested passes the debugging, execute S2 . By performing sequential control debugging on the built-in program in this embodiment, it can be ensured that the built-in program is normally executed when no fault or abnormality occurs.

In one of the embodiments, the S2: perform a destructive test on the built-in program and obtain a test result.

Wherein, the destructive test refers to that, before the programmed operation, the control conditions and/or confirmation conditions in the programmed operation process can be reversed manually or by other means to obtain the corresponding destructive control conditions and/or corresponding destructive confirmation conditions. The process of performing programmed operations under said corresponding destructive control conditions and/or corresponding destructive confirmation conditions. For example: the confirmation condition after the switch is opened is that the primary current disappears when the circuit breaker is opened during the sequence control debugging. In the destructive test, the determined condition after the switch is opened is to open the circuit breaker but the primary current does not disappear. Another example: the control condition before closing the ground knife of the line is that there is no voltage on the line before the ground knife is closed during the sequence control debugging. In the destructive experiment, the control condition before closing the ground knife is that there is voltage on the line before closing the ground knife. In addition, the built-in program of the intelligent substation to be tested can also send a "total accident" signal, etc.

Specifically, the control conditions and/or confirmation conditions in the built-in program are reversed, so that the built-in program works under the reversed control conditions and/or confirmation conditions, and the test results are obtained. Through the destructive test performed on the built-in program in this embodiment, it can be ensured that the programmed flow can be interrupted normally in case of failure or abnormality, thereby reducing the risk of misoperation. At the same time, it can detect faults in time, prevent the faulty equipment from being put into operation, and avoid the derived hazards. Greatly improve the reliability and stability of programmed operation.

In one embodiment, the S3: determine the acceptance result of the built-in program according to the test result.

Specifically, during the programmed operation process of the smart substation under test performing the transition from the initial state to the target state, the programmed operation process should be interrupted under the destructive control conditions of the destructive test and/or the corresponding confirmation conditions, then this item Destructive test passed. Otherwise, the destructive test fails. At this time, the supplier needs to be notified to deal with the relevant issues until the relevant issues are resolved. According to the acceptance result of this embodiment, it is possible to reasonably evaluate whether the built-in program is qualified, which can provide a reference for the optimization of the built-in program.

In one embodiment, the S1 includes: based on a preset initial state and a preset target state of the smart substation to be tested, acquiring an operation ticket corresponding to the built-in program of the smart substation to be tested, and executing the operation Debug steps for the ticket. If the debugging steps of the operation ticket are completed, and the intelligent substation to be tested changes from a preset initial state to a preset target state, the built-in program is debugged through the sequence control. Otherwise, the built-in program fails the sequence control debugging. At this time, it is necessary to notify the supplier to deal with the relevant problems, and until the relevant problems are solved, S1 is re-executed to check the built-in program.

In one of the embodiments, the S2 includes:

S20: Initialize N=1.

S21: If under the Nth preset destructive condition, the built-in program is interrupted and the interrupted position is at the initial debugging condition corresponding to the Nth preset destructive condition, then the built-in program at the initial debugging condition is The program passes the acceptance and S22 is executed.

S22: Restore the Nth preset destructive condition of the built-in program to the initial debugging condition, and set N=N+1, and return to S21 until N>Z.

In the above formula, N∈[1,Z], Z is the total number of the preset destructive conditions.

The preset destructive conditions can be divided into five categories, and the first category is the preset signal-type destructive conditions. For example, the background does not send out "GOOSE general alarm" signal, "SV general alarm" signal, "accident general" signal, "protection device blocking" signal, "control loop disconnection" signal, etc. The second category is the destructive condition selected by the preset control method. For example, the control mode selection of the measurement and control screen is switched to "remote", the mechanism control mode is selected to be switched to "distant", etc. The third category is the preset pressure plate-like destructive conditions. For example: put into differential protection pressure plate, put into maintenance pressure plate and so on. The fourth category is the preset current-type destructive conditions. For example: after disconnecting the switch, check that the three-phase primary current does not exceed 2A, etc. The fifth category is the preset digital destructive condition. For example: switch, knife switch, position of ground knife, etc.

Specifically, the destructive test operation is performed according to the order of the preset destructive conditions in the built-in program, and when the built-in program passes the destructive test under the Nth preset destructive condition, the Nth destructive test is restored. The debugging conditions of the initial sequence control corresponding to the preset destructive conditions are set, and a destructive test under the next preset destructive condition is performed until all the preset destructive conditions are executed, and the test results of the destructive test are obtained. Through the operation of this step, it can be ensured that all preset destructive conditions are detected to avoid omission.

In one embodiment, the step S3 includes: if the built-in program is interrupted under each preset destructive condition and the interrupt position is the initial debugging condition corresponding to the corresponding preset destructive condition, then The result of acceptance of the built-in program is qualified. If the built-in program is not interrupted under the preset destructive conditions and/or the interruption position is not at the initial debugging condition corresponding to each of the corresponding preset destructive conditions, the result of acceptance of the built-in program is unqualified. At this time, it is necessary to notify the supplier to deal with the relevant problems, until the relevant problems are solved, and the destructive test shall be carried out again.

In one embodiment, the process of acquiring the preset destructive condition includes: inverting the debugging condition in the sequential control debugging to obtain the preset destructive condition.
