Before the power dispatching operation is started, whether an executable operation item exists currently needs to be judged, the operation item refers to a detailed operation step of an electrical operation in an operation ticket, and the operation ticket refers to a written basis for performing the electrical operation in a power system and comprises a dispatching instruction ticket and a power transformation operation ticket. In the checking process, only one ticket is checked currently, but more than one operation ticket is executed, and there may be operations being executed or ordered; the operation items in the operation ticket are checked or executed from top to bottom. The operation monitoring system is an open third-party system, and electrical characteristics and power data in various power dispatching processes are stored inside the operation monitoring system.
The operating devices refer to switches, disconnecting switches, grounding disconnecting switches, and the like in the power system. The state checking module is used to ensure that the operated device, such as a switch, is consistent with the initial state and is not in the target state before the power dispatching operation, for example, if the instruction of the operation item is to close the switch, and at this time, it needs to check whether the switch is in the open state, and if so, it can be checked. The safety check module and the state check module are executed before order.
It should be noted that, in the multi-ticket checking module, it is necessary to suspend the execution tasks except for checking, that is, suspend other executing operation items, and then lock the executing operation ticket, in order to ensure the validity of the acquired data, it is necessary to suspend the executing task, and all the operation items that have not yet been executed at the moment of suspension are acquired; including the operation items not yet executed in the operation ticket being executed or the operation items being executed. And simulating the obtained operation tickets to obtain results, namely sections, after tasks are executed according to operation items in the operation tickets, and checking the simulated sections to obtain checking results, wherein the checking mechanism is to check switches, disconnecting links and grounding disconnecting links related to the operation of electric appliances in the power system according to a 'five-prevention' principle in the power system. Because similar or identical operation items exist in the unexecuted operation tickets or the operation items, and the operation items have mutual influence in the execution process, the operation tickets need to be correlated through a multi-ticket checking module, whether the section of the operation ticket influences the currently checked operation item is checked, whether the checking result reaches a preset index is judged, if yes, the checking is passed, no influence is shown, if not, the checking is not passed, the unexecuted operation item influences the currently checked operation item is shown, and an alarm prompt is given.
It should be noted that in this embodiment, all the checking modules or checking operations need to determine whether the checking passes, and the next checking or operation is triggered only after the checking passes, and all the checking modules pass through to reach the instruction for executing the operation item of the current checking.
In the power dispatching error-proof checking device provided by the application, the specific operation items of the operation tickets in the power dispatching process are checked through the plurality of checking modules, specifically, the order statements of the power dispatching operation instructions and the corresponding operation equipment are checked through the safety checking module, so that the normalization of the order statements in the power dispatching operation process is ensured, the order statements of the dispatching operation are consistent, and the dispatching error operation is avoided in the aspect of the order statements; in addition, multiple operations in the power scheduling process are associated through the multi-ticket checking module, the overall logic of all the operations is considered, checking of various operations is not considered in an isolated mode in the prior art, and scheduling misoperation is avoided from the aspect of mutual influence among multiple operation instructions.
For convenience of understanding, please refer to fig. 2, an embodiment two of the power scheduling mis-checking prevention apparatus is provided in the embodiment of the present application, including:
the safety checking module 201 is configured to check whether the instructed units of the order statements of the power scheduling operation are correct and whether the instructed units are matched with the corresponding operating devices one by one based on real-time model data in the operation monitoring system, and trigger the state checking module after the checking is passed.
It should be noted that the safety check is to avoid the situation that the instruction statements before and after the operation are inconsistent to cause the power scheduling misoperation, specifically, the real-time model data in the operation monitoring system is used to check whether the instruction receiving unit of the statements in the power scheduling operation instruction is correct, if yes, the real-time model data in the instruction receiving unit is used to check whether the operation devices corresponding to the power scheduling operation instruction are matched, and in principle, the two are in a one-to-one correspondence relationship, so that once the instruction statements are not matched, the check is not passed.
The state checking module 202 is configured to check whether the initial states of the operating devices are consistent based on real-time device state data in the operation monitoring system before power scheduling operation, and trigger the multi-ticket checking module after the checking is passed.
The state check is mainly to ensure that the operated device, such as a switch, is consistent with an initial state and is not in a target state before the power dispatching operation, that is, if the command of the operation item is to close the switch, it needs to check whether the switch is in an open state, and if so, the check can be passed. The safety check module and the state check module are executed before order.
It should be noted that the state checking module 202 includes a topology checking module 2021, which checks an operation process of the preset device to obtain a corresponding topology checking result, where the preset device includes a switch, a disconnecting link and a grounding disconnecting link.
It should be noted that the topology checking module can be specifically divided into: the switch operation checking module, the disconnecting link operation checking module and the grounding disconnecting link operation checking module. Firstly, the switch operation checking module is mainly used for checking first electrical characteristics generated in the process of opening and closing a switch device to obtain a switch topology checking result, wherein the switch device comprises a common switch, a transformer high/medium voltage side switch, a wiring switch and a bus tie switch, and the first electrical characteristics comprise electrical island activity, electrical island number consistency, switch knife position, serial flash switch power-off sequence and bus connection points. The ordinary switch is a switch which has no influence on other electrical indexes relative to a transformer, a wiring or a bus-bar switch, and is only responsible for cutting off and connecting electric power. The specific checking comprises the following steps: after the switch is disconnected, if the electric island of any end node of the switch is judged to be changed from an active island to a dead island, the fact that the downstream bus is powered off due to the fact that the switch is disconnected is indicated; after the switch is disconnected, if the electrical island numbers of the nodes at the two ends of the switch are still the same, the disconnection of the switch can cause the ring-off of the system; when a high/medium voltage side switch of the transformer is disconnected, if the low voltage side switch is judged to be in a switching-on position and the high/medium voltage side neutral point ground switch is judged to be in a switching-off position, clear state prompt needs to be given; when the connection switch is disconnected 3/2, if the power failure sequence of the switches in the string is judged to be incorrect, clear action state prompt needs to be given; after the bus tie switch is disconnected, if the fact that each bus running in each row is not connected or not connected to a transformer with a grounded neutral point is judged, an error is prompted; before the switch is closed, if the island numbers of the electrical islands of the nodes at the two ends of the switch are judged to be the same, prompting that a closed switch system is closed; when a switch on the high/medium voltage side of the transformer is closed, if the neutral point ground brake on the high/medium voltage side of the transformer is judged to be in the open position; when the medium/low voltage side switch of the transformer is closed, judging that the high/medium voltage side switch of the transformer is in the separated position, and giving a corresponding state prompt; after the bus coupler switch is closed, if the condition that the buses running in parallel are connected with two or more grounded voltage transformers of neutral points is judged, a state prompt is given; and finally forming a switch topology checking result according to all the switch judgment results.
And secondly, the disconnecting link operation checking module is used for checking second electrical characteristics generated in the disconnecting link device in the processes of disconnecting, connecting and power cut to obtain a disconnecting link topology checking result, the disconnecting link device comprises a common disconnecting link, a bypass disconnecting link and a bus-coupled disconnecting link, and the second electrical characteristics comprise the attribute of an electric island at a disconnecting link end point, the opening and closing attribute of the disconnecting link and the bus-coupled interval running state. Wherein ordinary knife switch is exactly the ordinary knife switch who is different from bypass knife switch and female antithetical couplet knife switch, can not have the knife switch that influences these two electric indexes, and concrete check includes: before closing the disconnecting link, if any end node of the disconnecting link is judged to belong to the grounding island, operation prohibition is prompted; before the bypass disconnecting link is disconnected or switched on, if the opening end of the bypass is judged to be in the closed position, prompting that the operation of the disconnecting link of the bypass is forbidden; before disconnecting or switching on the disconnecting link, judging that the switch at the interval where the disconnecting link is positioned is in a closed position, and prompting to prohibit the operation of the disconnecting link; before the disconnecting link reverses the bus, judging that the bus coupling interval is in a non-running state, and prompting that the bus coupling interval is firstly converted into a running state; when power is off, judging that the load side disconnecting link is in the closing position, and prompting to forbid closing of the bus side disconnecting link; when power is transmitted, the bus side disconnecting link is judged to be in the open position, and the closing of the load side disconnecting link is prompted to be forbidden; and finally, generating a disconnecting link topology checking result according to all the disconnecting link operation checking results.
And then, a grounding disconnecting link operation checking module for checking a third electrical characteristic generated in the disconnecting and connecting processes of the grounding disconnecting link device to obtain a grounding disconnecting link topology checking result, wherein the grounding disconnecting link device comprises a common grounding disconnecting link, a line-side grounding disconnecting link and a bus grounding disconnecting link, the third electrical characteristic comprises whether a connecting band electric island, the switching attribute of the grounding disconnecting link and a bus voltage value are connected, and the common grounding disconnecting link is a grounding disconnecting link which is different from the line-side grounding disconnecting link and the bus grounding disconnecting link and does not directly influence the checked electrical characteristic, namely, a common grounding disconnecting link which is not restricted. The specific checking comprises the following steps: when the grounding knife switch is closed, judging that the grounding knife switch is connected with the electric island, and forbidding the live operation; when the grounding knife switch is closed, even if the grounding knife switch is connected to the power-off island, if any knife switch of the grounding knife switch lock chain is judged to be closed, closing of the grounding knife switch is forbidden; for the line side grounding disconnecting link, judging that voltage measurement exists on a line PT on any side of the line, and if the voltage value is greater than 0.65Un, forbidding closing the grounding disconnecting link; for the bus grounding disconnecting link, judging that the voltage of the bus is measured, and if the voltage value is greater than 0.65Un, forbidding closing the grounding disconnecting link; and finally, generating a grounding switch topology checking result according to all the grounding switch operation checking results.
It should be noted that the above switch operation checking, disconnecting link checking and grounding disconnecting link checking all belong to topology checking modules, and the topology checking is calculated to pass only after all the checking passes, but it should be noted that the topology checking can be triggered only by checking the initial state consistency of the operating device in the state checking.
It should be noted that the topology checking module 2021 further includes a power flow checking module 20211, which is configured to check a power flow change generated on a current section when the switch device is turned off or turned on, and make a corresponding prompt according to a preset threshold value. It should be noted that although the power flow checking module 20211 is in the topology checking module 2021, the power flow checking is mainly for the switch operation, that is, mainly studies the power flow change of the current section caused by the opening and closing of the switch, and it can be understood that the checking of the power flow is a more intuitive checking manner for the closing and opening of the switch. The threshold value of the convergence setting of the power flow calculation section is 97%, the equipment threshold value is 95%, and when the check value exceeds the preset threshold value, a corresponding prompt is given. Similarly, the power flow check can be triggered only after the topology check passes, and the next operation can be executed only after all the check passes.
The dangerous point checking module 203 is configured to be triggered after being checked by the state checking module, match the current operating device with a dangerous device in a defect library of the real-time power grid device, report a waiting operation instruction to the operating device if the matching is successful, and trigger the multi-ticket checking module if no matched dangerous device is found, where the dangerous device is a device with a dangerous point in power scheduling operation caused by a device defect.
It should be noted that the defect library of the power grid device is historical data, the recorded defect device needs to be checked when receiving the operation instruction again, and once the defect library matches with the device in the defect library, the executor needs to be notified to perform arbitration, and whether to execute the operation instruction. In addition, when the check device further comprises a dangerous point check module, the dangerous point check module can be triggered after the state check module passes the check, so that the dangerous point check module triggers the multi-ticket check module after the dangerous point check module passes the check.
The multi-ticket checking module 204 is configured to lock an executing operation ticket, acquire and simulate an unexecuted operation ticket or an executing operation ticket to obtain a cross section, check the simulated cross section to obtain a checking result, issue a scheduling instruction after the checking is passed, and trigger execution of an operation item.
It should be noted that the multi-ticket checking module 204 includes a locking sub-module 2041, an obtaining sub-module 2042, a section simulation sub-module 2043, a topology checking module 2044, and a display sub-module 2045.
The locking submodule 2041 is used for issuing an instruction and locking an executing operation order;
the obtaining sub-module 2042 is configured to filter and obtain all unexecuted operation tickets or operation tickets being executed;
the section simulation submodule 2043 is configured to perform real-time section simulation on the unexecuted operation ticket or the executing operation ticket acquired by the acquisition module, so as to generate a simulated section;
the topology checking module 2044 is configured to check the operation processes of various devices to obtain corresponding topology checking results, where the devices include a switch, a disconnecting link and a grounding disconnecting link;
it should be noted that the topology checking module 2044 can be divided into: the switch operation checking module, the disconnecting link operation checking module and the grounding disconnecting link operation checking module, and the specific checking process is already explained in the state checking module 202 clearly and is not described herein again; the topology checking module 2044 further includes a power flow checking module 20441, which is used to check the power flow change generated on the current section when the switching device is turned off or on, and make a corresponding prompt according to a preset threshold, which is also described in the state checking module 202 for clarity, and thus is not described again, and the operation instruction can enter the next operation link through checking.
It should be noted that, when performing multi-ticket checking on a certain operation item of a current operation ticket, the multi-ticket checking module needs to suspend execution tasks except for checking, and then lock the operation ticket being executed, that is, suspend other operation items being executed, in order to ensure validity of acquired data, the executed task needs to be suspended, so that all operation items of the operation ticket that have not yet been executed at the moment of suspension are acquired; including the operation items not yet executed in the operation ticket being executed. And simulating the acquired operation tickets to obtain the sections after executing tasks according to the operation items in the operation tickets, and checking the sections. Because similar or identical operation items exist in the unexecuted operation tickets or the operation items, and the operation items have mutual influence in the execution process, the operation tickets need to be correlated through a multi-ticket checking module, whether the section of the operation ticket influences the currently checked operation item is checked, whether the checking result reaches a preset index is judged, if yes, the checking is passed, no influence is shown, if not, the checking is not passed, the unexecuted operation item influences the currently checked operation item is shown, and an alarm prompt is given.
And the display submodule 2045 is used for displaying the checking result of the simulation section, issuing an instruction, and unlocking the locked operation order.
It should be noted that displaying the checking result of the simulation section means displaying the topology checking result and the power flow checking result; the suspended task needs to be released again so as to be continuously executed; the released task includes the locked executing operation ticket.
The command returning checking module 205 is used for checking whether the target states of the operating devices are consistent based on real-time device state data in the operation monitoring system before the power dispatching operation returns the command.
It should be noted that, the execution command can be issued only after all the checks are passed, so that the operation item is executed, and after the operation item instruction is executed, the command back check needs to be performed, which means that it is necessary to ensure that the target states of the executed device state pre-operation items are consistent, so as to ensure that the operation item instruction is accurately executed.
