Description
Technical Field
The invention belongs to the field of power supply safety, and particularly relates to a management method and a management system for a ground wire.
Background
In the power production, in order to ensure the safety of human bodies, power grids and equipment and avoid various misoperation accidents, misoperation prevention locking measures must be taken, and especially in the process of 'hanging ground wires' and 'picking ground wires', misoperation prevention management work needs to be strictly prevented.
The requirement of five prevention of electrical equipment is put forward by the domestic power system as early as 1990, and the management, operation, design and use principles of electrical anti-misoperation are regulated in a legal form.
The existing anti-misoperation locking system has three types according to different locking modes: mechanical type anti-misoperation locking system, electric type anti-misoperation locking system, microcomputer type anti-misoperation locking system.
However, each anti-mislatching method has certain disadvantages and shortcomings. For example, the mechanical anti-misoperation locking device mainly depends on the transmission of a mechanical mechanism, has many linkage links, and often has the phenomena of mechanism locking faults and the like in the operation process; electric anti-misoperation lockout device is established on the secondary operation return circuit, realizes the shutting function through the auxiliary contact of striing into circuit breaker and switch on the operation return circuit, need insert a large amount of secondary cables among the practical application, and the mode of connection is complicated, and the realization of the big station that the interval is many consumes a large amount of cables, and has switch auxiliary contact unreliable, outdoor electromagnetic lock mechanism fragile scheduling problem in service. The microcomputer anti-misoperation locking device is divided into two types: one is an off-line microcomputer anti-misoperation lockout, does not need to lay cables, has small investment, simple structure and wide application, but has the obvious defects that the problem of idle running is difficult to solve and real-time alignment with equipment cannot be realized. The other is online microcomputer anti-misoperation lockout, which can be aligned with equipment in real time to prevent the problem of idle running during operation, but the real-time alignment depends on communication reliability and does not provide a lockout function of remote control operation.
The existing anti-misoperation locking system mainly has the following three problems:
1) the misoperation of a single equipment object can be only prevented, and the existing anti-misoperation locking system can not provide effective anti-misoperation measures for cross-station operation, ground wire hanging and disconnecting and the like.
2) The existing anti-misoperation locking system only considers misoperation of operators and does not consider errors existing in the process of switching operation tickets and command issuing operations of dispatchers.
3) The existing anti-misoperation locking system does not consider misoperation caused by unauthorized unlocking of an operator. In the 131 misoperation accidents occurring in the years of 2003-2009 of a certain power grid, 25 misoperation accidents occur when the misoperation prevention device operates normally but workers do not unlock at will.
4) Misoperation of a grounding wire on a circuit is not considered; the national grid company's electric power safety work regulations states that when working on a power line, grounding wires must be installed strictly according to regulations, and safety measures of power failure, electricity testing and grounding wire hanging are implemented. However, a malignant misoperation accident caused by human factors cannot be avoided for a long time, a good solution is not provided in the aspects of technical means or management measures, and the installation and the removal of the grounding wire often depend on the subjective judgment of an operator.
In summary, the traditional ground wire management is mainly based on a system level, the ground wire state is difficult to monitor in real time, and if a power grid operator cannot know the ground wire state in real time, serious accident potential can be buried in a power system; in addition, omission of the ground wire is difficult to find in traditional ground wire management, and particularly after a period of time, the current position of the ground wire cannot be determined; finally, the traditional ground wire management does not consider the malignant accidents caused by human factors, and obvious holes exist.

Detailed Description
The invention is further illustrated with reference to the following figures and examples.
The switching operation needs to be completed by the cooperation of a power grid regulator and a field operator, the correct switching operation process comprises drawing up and checking of a switching operation ticket, the power grid regulator issues an instruction to the field operator on the basis of the correct checking of the switching operation ticket, the field operator starts to operate after repeating the operation without error, and the switching operation is completed by reporting to the power grid regulator after the operation is completed.
The operation steps of hanging and disconnecting the grounding wire are important work before switching operation, and in actual work, the probability of errors and mistakes in the operation steps is the largest in the whole switching operation link.
According to the technical scheme, the five-prevention operation rule is written into a rule row and summarized in the anti-error detection rule. The information within the "rule line" includes: an operating equipment object, an operating equipment state, a conditional equipment object, a conditional equipment state, an alarm prompt when the ticket is checked wrongly, and the like.
The technical scheme can be divided into three parts of error ticket prevention, error scheduling prevention and error operation prevention according to the realization function:
the function of preventing error tickets is to examine and verify operation tickets based on task detection rules, error detection prevention rules and process check rules. The task detection rule checks whether the initial state of the equipment in the operation ticket is consistent with the actual initial state of the operation object; the error detection prevention rule is a core rule for ensuring the correctness of the operation ticket, and prompts a regulator that partial operation is not allowed under a specific condition, and in order to ensure the correctness of the operation ticket, the system designs the error detection prevention rule to realize the one-by-one inspection of operation steps; the flow detection rule is to check whether the final state of the device in the operation ticket is consistent with the required final state (operation task) of the device.
The anti-misoperation scheduling function is based on an anti-misoperation detection rule, and the anti-misoperation logic judgment is carried out on the operation instruction to be sent currently according to the execution sequence of the operation tickets and the real-time topological state of the primary wiring diagram.
The function of 'misoperation prevention' is that according to a primary device two-dimensional code activated in the process of commanding by a controller, a field operator scans and confirms the code of the operation-simulated device, the intelligent lock is automatically unlocked after the code is scanned correctly, and the operator acquires the operation authority, which is a combination mode of soft locking and hard locking.
Specifically, when the operation steps of 'hanging and disconnecting the grounding wire' are carried out, the technical scheme provides a grounding wire management method based on two-dimensional code and intelligent lock technology, and the invention is characterized in that:

a dispatcher uses a dispatching end to assist in dispatching;
in the operation process of hanging and dismounting the ground wire of the power supply system equipment, a field operator uses a mobile terminal to assist work;
when ground wire hanging and disconnecting operations need to be carried out, a dispatcher activates a two-dimensional code of the simulated operation equipment on an operation ticket through a dispatching end, and a field operator scans the two-dimensional code of the equipment once through a mobile end; if the two are consistent, the system considers that the device object to be operated by the operator is correct, the intelligent lock is automatically unlocked, the next operation is allowed, and the operator acquires the operation authority; if the two are not consistent, the equipment object to be operated by the operator is considered to be wrong, and the system gives an alarm for prompting.
When an operator prepares to hang a ground wire, whether the ground wire is in a correct position is judged by scanning a two-dimensional code of an electric pole at the position where the ground wire is hung; if the code scanning is correct, the system remotely releases the corresponding intelligent lock and allows an operator to take out the grounding wire; after obtaining the grounding wire, an operator scans the two-dimensional code of the grounding wire, and the system automatically reads the corresponding serial number of the grounding wire and writes the serial number into an operation ticket; after the operation is finished, a dispatcher is reported through a system, and the real-time topological alignment of the primary wiring diagram is updated;
the dispatcher directly inquires the state of each grounding wire through the system and grasps the real-time position of the grounding wire.
As shown in fig. 2, the dispatcher uses the dispatching end to assist in dispatching work, and the dispatching work including the following work contents is performed through the dispatching end connected to the cloud platform:
1) importing an operation ticket, sending the operation ticket to a server by a scheduling end, and checking whether the operation ticket is correct or incorrect through entry retrieval and topological graph association;
2) according to the operation tasks, corresponding related tasks are sent to designated operators; the mobile terminal of the operator receives the corresponding task;
3) when a dispatcher sends a command operation, the cloud platform server automatically judges whether the operation meets the five-prevention standard according to the graphic topology and the logic judgment module, and if the operation does not meet the five-prevention rule, the cloud platform server gives an alarm to remind and informs the dispatcher;
4) and the dispatcher performs maintenance work on the cloud platform at the dispatching end and simply maintains key modules such as graphic topology, logic judgment and the like.
As shown in fig. 3, the field operator uses the mobile terminal to assist in the operation of hanging and disconnecting the ground wire from the power supply system equipment, and the operation includes the following steps:
1) the mobile terminal automatically receives an electronic operation ticket sent by a dispatcher, and software automatically identifies an operation task;
2) after the dispatcher finishes issuing the order, the operation working details are recorded and uploaded to cloud platform dispatching end software of the dispatcher through cloud platform service;

5) when the mobile terminal carries out related operations, the system automatically judges whether the operations meet the five-prevention standard according to the graph topology and the logic judgment module, if not, the unlocking fails or the alarm is reminded, and a dispatcher is informed to prevent misoperation of operators.
Further, when the ground wire is hung, an operator finds the position of the electric pole to be hung with the ground wire, and judges whether the position is the correct position or not by scanning the two-dimensional code of the electric pole at the position to be hung with the ground wire;
if the code scanning is correct, the operator acquires the operation authority; if the code scanning is wrong, the system sends out an alarm prompt of 'misoperation' and gives out specific error information to prevent the occurrence of the fault of hanging the ground wire in a live state due to the fact that an operator mistakenly climbs the live electric pole.
Furthermore, when the operation of removing the grounding wire is carried out, an operator finds the grounding wire to be removed, and judges whether the grounding wire is the correct grounding wire or not by scanning the two-dimensional code of the grounding wire;
if the code scanning is correct, the operator acquires the operation authority, and if the code scanning is wrong, the system sends out an alarm prompt of 'misoperation' and gives out specific error information so as to prevent the occurrence of the fault of the grounding switch-on switch.
In this technical solution, the device to be operated includes each grounding wire.

Typical misoperation in a substation comprises mistakenly pulling and closing a circuit breaker in the substation, and mistakenly entering a live interval; the misoperation of the substation outside line equipment is mainly the misoperation of the grounding wire, including mistaken hanging, missed hanging, mistaken dismounting and missed dismounting, and various human factors cause serious accidents such as live hanging of the wire and a grounding wire switch.
The traditional ground wire management is mainly based on a system level, the state of a ground wire is difficult to monitor in real time, and if a power grid operator cannot know the state of the ground wire in real time, serious accident potential is buried in a power system; in addition, omission of the ground wire is difficult to find in traditional ground wire management, and particularly after a period of time, the current position of the ground wire cannot be determined; finally, the traditional ground wire management does not consider the malignant accidents caused by human factors, and obvious holes exist.
Aiming at the problems, the technical scheme provides a ground wire management method and system based on a two-dimension code and an intelligent lock technology, and aiming at misoperation caused by human factors of operators.
As shown in fig. 4, the ground wire management system deploys the safety rules of preventing the ground wires from being hung and detached and the sequential logic of the power on/off switch on the cloud server based on the two-dimensional code and the intelligent lock technology, performs data processing by using the cloud computing technology, performs error-proof logic judgment in the whole process of auditing, issuing and operating based on the five-prevention rules, and realizes the error-proof locking in the whole network process of the ground wire hanging and detaching operation so as to effectively avoid the problems of irregular ground wire management, undefined ground wire state and unclear ground wire position; the occurrence of vicious accidents of live ground wire hanging, ground wire connection switch with connection and the like caused by human factors is prevented, the dispatching work efficiency is improved, and the safety and the reliability of field operation are enhanced.
According to the operation sequence (the line segment with an arrow in the figure represents the operation direction and the operation sequence), when the operation of hanging and disconnecting the grounding wire is needed, a dispatcher activates the two-dimensional code of the simulated operation equipment on the operation ticket through a dispatching end, and a field operator scans the two-dimensional code of the equipment once through a mobile end; if the two are consistent, the system considers that the device object to be operated by the operator is correct, the intelligent lock is automatically unlocked, the next operation is allowed, and the operator acquires the operation authority; if the two are not consistent, the equipment object to be operated by the operator is considered to be wrong, and the system gives an alarm for prompting.
When an operator prepares to hang a ground wire, whether the ground wire is in a correct position is judged by scanning a two-dimensional code of an electric pole at the position where the ground wire is hung; if the code scanning is correct, the system remotely releases the corresponding intelligent lock of the ground wire library and allows an operator to take out the ground wire; after obtaining the grounding wire, an operator scans the two-dimensional code of the grounding wire, and the system automatically reads the corresponding serial number of the grounding wire and writes the serial number into an operation ticket; after the operation is finished, a dispatcher is reported through a system, and the real-time topological alignment of the primary wiring diagram is updated; the controller can directly inquire the state of the grounding wire through the system background and master the real-time position of the grounding wire.
As shown in fig. 5, a controller performing a scheduling decision in a control center may perform a scheduling end work by connecting to a cloud platform server. The dispatching end has the following functions:
1. and (4) leading in the operation ticket by a controller, sending the operation ticket to a server by the main station side, and checking whether the operation ticket is correct or incorrect through entry retrieval and topological graph association.
2. And the regulator sends the corresponding related tasks to the appointed operators according to the operation tasks. And the mobile terminal of the operator receives the corresponding task.
3. When the regulator sends the command operation, the cloud platform server automatically judges whether the operation meets the five-prevention standard according to the graph topology and the logic judgment module, if not, the corresponding task is not received, the alarm is given, the regulator is informed, and the regulator is prevented from mis-regulating.
4. A regulator maintains the whole-network five-prevention intelligent scheduling system at the master station end, inputs key module information such as graphic topology and logic judgment, and ensures the stable operation of the system.
The misoperation accident of hanging the ground wire in a live-line manner is usually caused by the fact that an operator is neglected manually and climbs the live pole by mistake, and therefore the electric pole number is set on each electric pole in a two-dimensional code mode as a unique identifier in the technical scheme.
In fig. 6, the operation flow of the present invention for preventing the earth wire from being hooked in the live line is shown.
The operator finds the electric pole to be connected with the ground wire, scans the two-dimensional code of the electric pole to be connected with the ground wire by using the mobile terminal, uploads the scanned two-dimensional code, and the system judges whether the position is the correct position.
If the code scanning is correct, the operator acquires the operation authority; if the code scanning is wrong, the system sends out an alarm prompt of 'misoperation' and gives out specific error information.
In addition to the above-mentioned electrified ground wire hanging accident caused by mistaken climbing of the electrified pole, misoperation accidents such as mistaken detachment and missed detachment are easy to occur when the ground wire is detached, so that the terrible accident of the switch with the ground wire is caused.
In this regard, the present disclosure provides a monitoring and operation flow for preventing a ground switch from being connected, as shown in fig. 6.
The operator finds the position of the ground wire to be disconnected, the two-dimensional code of the ground wire to be disconnected is scanned by using the mobile terminal, the mobile terminal uploads the scanned two-dimensional code, and the system judges whether the ground wire is the correct ground wire or not.
If the code scanning is correct, the operator acquires the operation authority, and if the code scanning is wrong, the system sends out an alarm prompt of 'misoperation' and gives out specific error information.
The pole-mounted knife switch or the pole-mounted transformer on the power supply line has the defects of various quantity, complex specific operating conditions, incapability of meeting the requirements for certain safety distance and incapability of mounting an intelligent lock. Therefore, the technical scheme adopts the soft locking module to realize the two-dimensional code verification.
The two-dimensional code soft locking flow in the present technical solution is shown in fig. 7.
Before each step of operation, an operator scans and uploads the two-dimensional code of the to-be-operated equipment or the grounding wire through the mobile terminal, and the system checks the two-dimensional code information of the to-be-operated equipment to remind a regulator and the operator whether to operate.
In summary, according to the technical scheme of the invention, the anti-misoperation rule is deployed on the cloud server, the cloud computing technology is used for data processing, and the anti-misoperation logic judgment is performed in the whole process of auditing, issuing commands and operating based on the five-prevention rule, so that a set of ground wire management system is finally formed. The two-dimension code and intelligent lock technology is adopted, a ground wire management library is set, different soft and hard locking strategies are adopted according to actual conditions, and the problems that a traditional anti-misoperation locking system cannot prevent the ground wire from being hooked in a charged mode, a ground wire connection switch is arranged, and operators unlock misoperation without permission are solved; the method provides a good solution for misoperation hidden dangers such as live grounding, grounding switch-on and switch-off with grounding in the outside line operation for a long time.
The system is promoted from the error prevention of equipment in a substation to the error prevention of the whole power grid equipment, extends the concept of five prevention, enlarges the protection range, breaks through the traditional thought based on mechanical and electrical error-prevention locking, and solves the defect that the traditional error-prevention locking system cannot prevent the misoperation of line equipment; the method is promoted from the anti-misoperation in the aspect of operators to the anti-misoperation in the whole process of auditing, issuing and operating, and fills the blank that the traditional anti-misoperation locking system only considers the misoperation of the operators; the anti-misoperation rule is arranged on the cloud server, and regulators and operators can master the real-time state of the whole-network electrical equipment and the real-time process of the operation work of hanging and disconnecting the ground wire through the client, so that the safety and the reliability of the whole switching operation process are improved.
The invention can be widely applied to the field of power grid power dispatching and operation management.
