Description

Technical Field

[0001] The present invention relates to the technical field of intelligent substations, and in particular to a substation-level one-button sequential control method and system based on combined interval thinking. Background Art

[0002] Substations are a vital component of the power system, converting high-voltage grid electricity into low-voltage power for power users. Substation one-touch sequential control technology uses advanced automation equipment and intelligent systems to enable remote monitoring, control, and operation of substation equipment. The basic principle is to transmit status information of various substation devices to a monitoring center through information transmission and data processing, and then remotely control and operate the equipment through the central system.

[0003] However, in the actual one-button sequential control process, in addition to the conventional single-bay decommissioning and recommissioning operations, the switching operation requirements of the daily operation and maintenance work of substations mainly based on 110kV are mainly concentrated on the large-scale operation mode switching at the station level. One operation task often involves the operation of equipment in multiple bays, which increases the operation difficulty for the operation and maintenance personnel. Summary of the Invention

[0019] According to one aspect of the present invention, the switching strategy for all interval operation modes of the virtual combined interval according to the operator's regulations requires defining the sequential control operation ticket as follows:

[0020] Create a sequence control operation ticket object in the sequence control configuration tool according to the switching strategy of the interval operation mode of each virtual combination interval, and describe its sequence control direction.

[0026] The operation ticket verification tool is configured with an interval scheduling number confirmation function before the sequential control operation ticket is verified;

[0027] The operation ticket verification tool visually verifies the operation conditions, locking signals and target status of the operating equipment of the sequential control operation ticket;

[0028] Sequential control operation tickets that have not been successfully verified by the operation ticket verification tool are not allowed to be called for execution;

[0029] The operation ticket verification tool supports the start of a simulation verification process, and assists in verifying the operation object, operation item sequence, pre-execution conditions, confirmation conditions, and error prevention rules of the sequential control operation ticket by simulating the execution process of the sequential control operation ticket.

[0054] Select the virtual combination interval, source operation mode, and target operation mode, match the corresponding sequence control operation ticket, and perform the sequence control execution operation after the rehearsal is successful.

[0055] Furthermore, according to an embodiment of the present invention, the virtual combined interval is defined according to the substation voltage level type as follows:

[0056] The substation is defined as multiple virtual combined bays according to voltage levels (such as 10kV, 110kV, 220kV, etc.), and corresponding virtual combined bay objects are created in the database.

[0057] Furthermore, according to an embodiment of the present invention, a corresponding sequence control interval is defined according to the virtual combination interval, and an association relationship is established with the virtual combination interval as follows:

[0058] Create a corresponding sequence interval object in the sequence configuration tool based on the virtual combined interval, and associate the corresponding virtual combined interval with the primary interval property of the sequence interval.

[0059] Furthermore, according to one embodiment of the present invention, all interval operation modes of the virtual combined interval are defined according to the operator's regulations as follows:

[0060] Create the corresponding interval status object in the database according to the substation operation regulations (i.e., substation operation and maintenance operation specifications and requirements), and then create the interval operation mode of all virtual combined intervals (such as operation side 1, operation side 2, ..., operation side N) in the sequential control configuration tool, and establish an association relationship with the corresponding sequential control interval, and each interval operation mode only matches one of the interval status objects.

[0061] Furthermore, according to an embodiment of the present invention, the switching strategy requirements for all interval operation modes of the virtual combined interval are defined as follows:

[0062] According to the switching strategy of the interval operation mode of each virtual combination interval (such as transport side X→ transport side Y), a sequence control operation ticket object is created in the sequence control configuration tool, and its sequence control direction is described.

[0063] Furthermore, according to an embodiment of the present invention, configuring a sequential control operation ticket according to the transporter switching operation ticket text file includes:

After a successful preview, the sequence control execution operation is performed as follows:

[0073] After selecting the virtual combination interval, source operation mode, and target operation mode on the one-click sequential control execution interface of the operation ticket verification tool, match the corresponding sequential control operation ticket from the sequential control operation ticket library. After a successful rehearsal, perform the sequential control execution operation, including:

[0074] The one-button sequential control execution interface should support the selection of virtual combination intervals, source operation mode, and target operation mode;

[0075] The one-key sequence control execution interface should support matching the corresponding sequence control operation ticket from the sequence control operation ticket library;
