Description

Technical Field

[0001] The present invention relates to the technical field of operation error prevention, and in particular to a method and system for preventing power grid ontology state errors based on a control cloud. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.

[0003] At present, the microcomputer five-defense system is used in substations, and the five-defense rule form is used to prevent errors in substation operations. In the integrated control mode, the control center uses the master station five-defense system to operate the substation circuit breaker, uses the communication protocol to call the five-defense rule form in the substation microcomputer five-defense, and uses the inter-station topology five-defense algorithm to prevent errors, forming a master-substation integrated five-defense mode of the control center substation. Through the data acquisition program, the substation five-defense data is collected and sent to the data processing program of the master station five-defense application. The substation five-defense data mainly includes the control five-defense model and the substation five-defense rule form.

[0004] Although the existing five-defense system of substations and the integrated five-defense system of control centers have been well applied at the substation end and the control main station end, the control cloud, as the provincial control management end, is in charge of all primary power grid equipment in the province. If the five-defense rule formulas of all substations are collected as the anti-error rule knowledge base of the control cloud, it is necessary to establish communication protocols with each substation. The project workload is huge and the cost is too high. At the same time, due to the frequent transformation of substations, the rule formula needs to be changed accordingly in real time. If it is not updated in time, it is easy to make verification errors when performing secondary verification of the operations of each control center. Therefore, due to the lack of any anti-error rule base in the control cloud, it is impossible to perform accurate secondary verification of remote control operations in the province, and it is impossible to grasp the anti-error constraint level of the province. Summary of the invention

[0005] In order to solve the above problems, the present invention proposes a method and system for preventing errors in the state of a power grid based on a control cloud. By constructing a knowledge base for preventing errors in the state of a power grid in the control cloud, all equipment in the power grid can be prevented from operating errors without calling on the five-prevention rule formula of the substation, which greatly saves the implementation cost of cloud-based error prevention verification.

[0006] To achieve the above objectives, the present disclosure adopts the following technical solutions:

[0007] First, a method for preventing errors in the state of the power grid based on the control cloud is proposed, including:

[0008] Get remote control operation instructions;

[0009] The operation type and operation object device of the remote control operation instruction are determined through the power grid body status error prevention knowledge base, and it is judged whether the operation object device is equipped with remote signaling. If so, the current state of the operation object device is obtained, and the operation type is prevented from error operation according to the current state of the operation object device.

[0010] Secondly, a power grid status error prevention system based on control cloud is proposed, including:

[0011] An instruction acquisition module, which acquires remote control operation instructions;

[0012] The anti-misoperation module is used to determine the operation type and operation object device of the remote control operation instruction through the power grid body status anti-misoperation knowledge base, judge whether the operation object device is equipped with remote signaling, and if so, obtain the current state of the operation object device, and perform anti-misoperation on the operation type according to the current state of the operation object device.

[0013] In a third aspect, an electronic device is proposed, comprising a memory and a processor, and computer instructions stored in the memory and executed on the processor, wherein when the computer instructions are executed by the processor, the steps described in a method for preventing errors in the state of a power grid based on a control cloud are completed.

[0014] In a fourth aspect, a computer-readable storage medium is proposed for storing computer instructions. When the computer instructions are executed by a processor, the steps described in a method for preventing errors in the state of a power grid based on a control cloud are completed.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present disclosure constructs a knowledge base for preventing errors in the power grid status in the control cloud, which eliminates the need to call upon the five-prevention rule formula of the substation, thus greatly saving the implementation cost of cloud-based anti-error verification.

[0017] 2. The switches, knife switches, ground switches and signboards disclosed in this invention are for the entire network. The research object will be the entire jurisdictional power grid. It is no longer like the traditional substation five-protection system that only targets a single device or a single substation. The main body status error prevention system is a universal maintenance-free error prevention system. It will not be maintained due to changes in the power grid, nor will it be maintained due to changes in operating modes, thereby reducing the maintenance workload as much as possible and improving practicality.

[0018] Advantages of additional aspects of the present invention will be given in part in the following description, and in part will become obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1

[0031] In this embodiment, a method for preventing errors in power grid status based on a control cloud is disclosed, including:

[0032] Get remote control operation instructions;

[0033] The operation type and operation object device of the remote control operation instruction are determined through the power grid body status error prevention knowledge base, and it is judged whether the operation object device is equipped with remote signaling. If so, the current state of the operation object device is obtained, and the operation type is prevented from error operation according to the current state of the operation object device.

[0034] Furthermore, the process of determining the operation type of the remote control operation instruction is as follows:

[0035] Determine whether the remote control operation instruction is a hang sign;

[0036] When it is not a listing, determine whether it is a demolition;

[0037] When it is not a card removal operation, determine whether it is a ground knife operation type;

[0038] When the operation type is not a ground knife, determine whether the operation type is a switch;

[0039] When the operation type is not a switch, determine whether the operation type is a knife switch.

[0040] Furthermore, the current state of the operation object device is determined by acquiring the remote signal value of the operation object device.

[0041] Furthermore, the power grid ontology state error prevention knowledge base is built based on the control cloud platform, and the ID of the operation object and the remote signal of the operation object device are obtained from the control cloud.

[0042] Furthermore, for each remote control operation instruction, an entity unit in the power grid entity state error prevention knowledge base is used as an object unit of remote control operation, and the operation object, operation type, and state value are used as the characteristics of the entity unit. The power grid entity state error prevention knowledge base obtains the ID of the operation object from the control cloud, determines the operation object device, obtains the remote signal of the operation object device from the control cloud, and determines the current state of the operation object device.

[0043] Furthermore, the operation objects include signboards, ground switches, knife switches and switches; the operation types include pulling open, closing, hanging and removing.

[0044] Furthermore, whether the operation object device is equipped with telesignaling is determined by whether the operation object device has a default telesignaling object and telesignaling point number.

[0045] A method for preventing errors in the state of a power grid based on a control cloud disclosed in this embodiment is described in detail.

[0046] At present, the provincial and local EMS models (voltage level of 35kV and above) have been organized into a large EMS model for the whole province, and the EMS large model has been imported into the control cloud power grid model cloud platform. The remote control operation of the control master station mainly adopts the substation call five-defense rule formula and the five-defense rules between stations to prevent error constraints. The control cloud lacks any anti-error rule library, and it is impossible to perform secondary verification of the remote control operations in the whole province, and it is impossible to grasp the anti-error constraint level of the whole province.

[0047] Therefore, the current control cloud has built all power grid equipment of all voltage levels above 35kV in the province, and has recorded the remote control operation process of all equipment in the province. However, when performing secondary verification on the cloud for the operation of each device, there is a lack of error-proof verification of the equipment itself, resulting in the inability to correctly verify the situation where the equipment cannot be operated due to its own reasons, and the cloud verification capability is greatly reduced.

[0048] In order to solve the above technical problems, this embodiment discloses a method for preventing errors in the state of a power grid entity based on a control cloud. An error prevention rule knowledge base is established in the control cloud. Error prevention verification is performed based on the operation type of the equipment and the state of the entity at the time of equipment verification. It does not rely on the five-prevention rule formula, and the verification capability is greatly improved.

[0049] A method for preventing power grid status errors based on control cloud, such as Figure 1 As shown, including:

[0050] S1: Get remote control operation instructions.

[0051] S2: Determine the operation type and operation object device of the remote control operation instruction through the power grid status error prevention knowledge base; determine whether the operation object device is equipped with remote signaling; if there is remote signaling, obtain the current state of the operation object device; and perform error prevention on the operation type of the operation object according to the current state of the operation object device.

[0052] Among them, the power grid ontology state error prevention knowledge base is constructed in the control cloud platform using the power grid ontology state error prevention knowledge unit construction technology.

[0053] For each remote control operation instruction, the extension principle is applied to take an entity unit in the power grid entity state error prevention knowledge base as an object unit of remote control operation, and the operation object, operation type and state value are taken as the characteristics of the entity unit, where the entity unit is:

[0054]

[0055] in,

[0056]

[0057]

[0058]

[0059] The operation type of the remote control operation instruction is determined by the power grid state error prevention knowledge base, and the power grid state error prevention knowledge base obtains the ID set and telesignal value of the primary device, that is, the operation object, from the control cloud. The ID set is EqID = {EqID1, EqID2, ..., EqID k ,...,EqID n}, control the EqID of the cloud device k The remote signal value set is YXv={YXv k1 ,YX k2 ,...,YXv kt}, t is the time that needs to be verified, the operation object device of the remote control operation instruction is determined by the ID of the operation object, and the current state of the operation object device is determined by obtaining the remote signal of the operation object device.

[0060] Determine whether the operation object device is equipped with remote signal; if there is no remote signal, lock it; if there is remote signal, obtain the current state of the operation object device; prevent the operation type from misoperation according to the current state of the operation object device.

[0061] The specific process of checking whether the operation object device has telesignaling is as follows: determine whether the operation object device has a default telesignaling object and telesignaling point number. If so, it means that the operation device is equipped with telesignaling. If not, it means that the operation device has no telesignaling.

[0062] The operation objects can be divided into signboards, ground switches, knife switches and switches according to the function type judgment method; the operation types include opening, closing, hanging and removing.

[0063] The process of determining the remote control operation command operation type is:

[0064] Determine whether the remote control operation instruction is a hang sign;

[0065] When it is not a listing, determine whether it is a demolition;

[0066] When it is not a card removal operation, determine whether it is a ground knife operation type;

[0067] When the operation type is not a ground knife, determine whether the operation type is a switch;

[0068] When the operation type is not a switch, determine whether the operation type is a knife switch.

[0069] The control cloud calls the corresponding entity error prevention logic according to the characteristic value of the operation object of the entity unit, and outputs the result of allowing the operation to be executed or locking the operation.

[0070] When the remote control operation instruction is determined to be a signboard operation, the signboard operation error prevention is performed. The signboard operation error prevention determines the correctness of the signboard operation by performing matrix operations on the type of signboard, the type of signboard before the signboard, the type of the signboard device itself, and the current state of the signboard device. The operation matrix used is:

[0071]

[0072] Through the operation matrix, the error-proof verification result of the sign-out operation is obtained, specifically, the two results of allowing the execution of the operation and locking the operation.

[0073] The types of signage and the types of signage that existed before the signage were calculated according to the general principle, and all signage types were traversed to participate in the calculation, such as hot standby signage, cold standby signage, maintenance signage, manned signage, test signage, ground wire, grounding signage, no closing signage, no opening signage, no operation signage, power supply signage, power protection signage, fault signage, malfunction signage, defect signage, out-of-service signage, etc.; among them, cold standby signage, maintenance signage, manned signage, test signage, ground wire, grounding signage, no closing signage, no opening signage, and no operation signage are operation type signs, and hot standby signage, power supply signage, power protection signage, fault signage, malfunction signage, defect signage, and out-of-service signage are status signs; the types of equipment to be listed include line switches, main transformer switches, busbars, lines, transformers, capacitors, capacitor switches, etc., and the current status of the equipment includes open and closed states.

[0074] Ideas to prevent mistakes in listing operations:

[0075] When there is a sign for someone working on the equipment, it can be directly replaced with the sign corresponding to the current sign type;

[0076] For equipment with other operation type signs (i.e. cold standby sign, maintenance sign, test sign, ground wire, grounding sign, no closing sign, no opening sign, no operation sign) except for the manned sign, the current sign operation will be locked;

[0077] When there is no operation type sign for the equipment and the sign type is one of the grounding sign, maintenance sign, ground wire, cold standby sign, and manned work sign, if there is any of the power sign, power protection sign, and hot standby sign, or if there are no signs of the above three types, but the operation object is a switch and the remote signal is closed, the current sign operation will be locked;

[0078] Execution is allowed when there is no operation type sign for the equipment and the sign type is a status sign.

[0079] The specific process of preventing errors in the sign-out operation is as follows: Figure 2 As shown:

[0080] (11) Determine whether there is an operation type card for the current hanging equipment. If there is an operation type card and it is a manned work card, there is no constraint, the anti-mistake check of the hanging card is passed, and the corresponding hanging operation is allowed; if there are other operation type cards except the manned work card, an alarm is given on the operation interface that the current equipment already has an operation type card, and the operation is terminated; if there is no operation type card, enter (12);

[0081] (12) The signboard types are determined in turn as ground signboard, maintenance signboard, ground wire signboard, cold standby signboard, and manned work signboard. If it is determined to be one of the above five signboard types, proceed to (13); if it is determined not to be one of the above five signboard types, proceed to (15);

[0082] (13) The existing sign types before the sign is posted are judged as hot standby sign, power sign, and power protection sign in turn. If it is determined that there is a hot standby sign, power sign, or power protection sign before the sign is posted, it is judged as an erroneous operation, the operation is terminated, an alarm is given on the operation interface, and the error prevention check record is saved; otherwise, enter (14);

[0083] (14) Determine whether the hanging device is a switch and its remote signal is in the closed position. If the determination result is true, it is determined to be an erroneous operation, the operation is terminated, an alarm is given on the operation interface, and the error prevention verification record is saved; otherwise, enter (15);

[0084] (15) If the error prevention check is passed, the corresponding listing operation is allowed.

[0085] When it is determined that the remote control operation command is not a sign-hanging operation, it is determined whether it is a sign-removing operation. If it is a sign-removing operation, it enters the sign-removing operation error prevention. The principle of the sign-removing operation error prevention is the same as the sign-hanging operation error prevention, but only the type of sign removed and the type of sign existing before the sign is removed are considered. The operation matrix used is:

[0086]

[0087] Ideas to prevent mistakes when removing cards:

[0088] (a) Constraint logic is only used for the removal signs of grounding sign, ground wire, maintenance sign, and prohibition of closing sign;

[0089] (b) When removing the grounding sign or ground wire sign, if there is a maintenance sign or a staff sign before the operation, the current sign removal operation will be locked;

[0090] (c) When performing the card removal operation of the maintenance card and the prohibition card, if there is a work card before the operation, the current card removal operation will be locked;

[0091] (d) The remaining types of splitting are allowed to be executed after it is determined that they are not the 4 types of splitting in (a).

[0092] The specific process of preventing mistakes in removing cards is as follows:

[0093] (21) Determine whether the current operation is to remove the ground plate (or ground wire). If so, proceed to (22); otherwise, proceed to (24);

[0094] (22) Determine the type of card that exists before the card is removed. If there is a maintenance card (or a manned card) before the card is removed, the operation interface prompts "Maintenance card 0 exists!" (or "Manned card 0 exists!"), and records it in the error prevention check record. The process ends. Otherwise, enter (23);

[0095] (23) Execute the current card removal operation and the process ends;

[0096] (24) Determine whether the current operation is to remove the maintenance card (or prohibit closing card), if so, go to (25), otherwise go to (23);

[0097] (25) Determine the type of cards that exist before the cards are removed. If there is a working card before the cards are removed, the operation interface prompts "There is a working card 0!" and records it in the anti-error verification record. The process ends. Otherwise, enter (23).

[0098] Determine whether the remote control operation type is a ground knife operation. If yes, enter the ground knife operation error prevention. The ground knife error prevention is mainly based on the ground knife operation type and the card type and the previous state of the ground knife before the ground knife operation. The operation matrix used is:

[0099]

[0100] The operation types of the ground knife include pulling open and closing. The types of signs before the operation of the ground knife can be divided into prohibited opening sign, maintenance sign, fault sign, prohibited operation sign, malfunction sign, someone working sign, prohibited closing sign, defect sign, out of service sign, etc. The previous status of the ground knife includes open and closed.

[0101] Ideas to prevent errors in ground cutter operation:

[0102] (1) The ground cutter is hung with a test sign, and both opening and closing operations are allowed;

[0103] (2) The ground cutter is hung with a decommissioning sign, and both the opening and closing operations are locked;

[0104] (3) If the current state of the ground knife is the target state, the operation is locked;

[0105] (4) If the earth switch is hung with a maintenance sign, fault sign, prohibited operation sign, malfunction sign, someone is working sign, prohibited closing sign, or defect sign, the operation will be locked. If the earth switch is pulled open, the operation will also be locked if a prohibited opening sign is hung.

[0106] The process of preventing errors in ground cutter operation is as follows: Figure 3 Shown are:

[0107] (31) First, determine whether there is a test card for the ground cutter to be operated. If there is a test card, the anti-error check is passed and the corresponding operation is allowed; if there is no test card, enter (32).

[0108] (32) Determine whether there is a suspension sign for the ground cutter to be operated. If there is a suspension sign, it is judged as an erroneous operation, the operation is terminated, an alarm is given on the operation interface, and the error prevention check record is saved. If there is no suspension sign, enter (33);

[0109] (33) Determine whether this operation is a pull-out operation. If not, proceed to (34). If it is a pull-out operation, prioritize the determination of a gate-disconnection prohibition card. If there is a gate-disconnection prohibition card, determine it as an erroneous operation, terminate the operation, and issue an alarm on the operation interface. Save the error prevention check record. If there is no gate-disconnection prohibition card, proceed to (34).

[0110] (34) Check the maintenance sign, fault sign, prohibited operation sign, malfunction sign, someone working sign, prohibited closing sign, and defect sign in sequence. If the corresponding sign exists, it is judged as an erroneous operation, the operation is terminated, and an alarm is given on the operation interface. The error prevention check record is saved. If none of the above signboards exist, the error prevention check passes and the corresponding opening and closing operations are allowed.

[0111] Determine whether the operation type of the remote control operation instruction is a switch operation, then enter the switch operation check to prevent errors. The judgment logic is the same as the grounding switch. In addition, the switch needs to add a judgment on whether it is isolated. If it is isolated, it can still be opened and closed when a maintenance sign is hung.

[0112] Ideas to prevent mistakes in switch operation:

[0113] The switch is hung with a test plate, and both opening and closing operations are allowed;

[0114] The switch is hung with a decommissioning sign, and both opening and closing operations are locked;

[0115] If the current state of the switch is the target state, the operation is locked;

[0116] If the switch is hung with a fault sign, a prohibited operation sign, a malfunction sign, an someone working sign, a prohibited closing sign, or a defect sign, the operation will be locked. If the switch is pulled open and the ground switch is hung with a prohibited opening sign, the operation will also be locked.

[0117] If the switch is hung with a maintenance sign, and the switch is allowed to be operated in the maintenance state, the switch is standardly wired, the switch is adjacent to the knife switch and the remote signal is in the closed position, and the switch has been isolated, the opening and closing operations are allowed; if any of the above four conditions is not met, the operation will be locked.

[0118] In other cases, both opening and closing of the switch are allowed.

[0119] The switch operation error prevention process is as follows Figure 4 Shown are:

[0120] (41) First, determine whether there is a test card for the switch to be operated. If there is a test card, the anti-mistake check is passed and the corresponding operation is allowed; if there is no test card, enter (42).

[0121] (42) Determine whether there is a decommissioning sign on the switch to be operated. If there is a decommissioning sign, it is judged as an erroneous operation, the operation is terminated, an alarm is given on the operation interface, and the error prevention check record is saved. If there is no decommissioning sign, enter (43);

[0122] (43) Determine whether the current operation is a pull-out operation. If not, proceed to (44). If it is a pull-out operation, prioritize the determination of a gate-disconnection prohibition card. If there is a gate-disconnection prohibition card, determine it as an erroneous operation, terminate the operation, and issue an alarm on the operation interface. Save the error prevention check record. If there is no gate-disconnection prohibition card, proceed to (44).

[0123] (44) Perform fault sign, prohibited operation sign, malfunction sign, manned work sign, prohibited closing sign, and defect sign judgment in sequence. If the corresponding sign exists, it is judged as an erroneous operation, the operation is terminated, and an alarm is issued on the operation interface. The error prevention verification record is saved. If the above sign is judged not to exist, enter (45);

[0124] (45) Check the maintenance card. If the maintenance card does not exist, the error prevention check is passed and the corresponding opening and closing operations are allowed. If the maintenance card exists, enter (46);

[0125] (46) The switch is allowed to be operated in the maintenance state, the switch is in the standard wiring, the switch is adjacent to the knife switch and the remote signal is closed, and the switch has been isolated. If any of the conditions is not met, it is judged as an erroneous operation and the operation is terminated. An alarm is issued on the operation interface and the error prevention check record is saved. If all four conditions are met, the error prevention check passes and the corresponding opening and closing operations are allowed.

[0126] Determine whether the operation type of the remote control operation command is knife switch operation, then enter the knife switch operation error prevention process, the judgment logic is the same as the ground knife, the knife switch operation error prevention process is as follows Figure 5 shown.

[0127] The present invention is aimed at the operation of switches, knife switches, earth switches and signboards in the entire network. It identifies various signboard types, switch, knife switch and earth switch states through the constructed power grid body state error prevention knowledge base, judges the equipment operation type, and realizes corresponding operation error prevention. The operation error prevention through the power grid body state error prevention knowledge base is universal and maintenance-free.

[0128] This disclosure applies the extension principle to the operation error prevention of primary equipment in the power system for the first time, takes an ontology unit in the knowledge base as an operation object unit, and the operation object, operation type, and state value as the characteristics of the ontology unit, and transforms the equipment error prevention into an analysis of the ontology unit and the ontology characteristics.

[0129] The switches, knife switches, ground switches and signboards disclosed in the present invention are aimed at the entire network and will take the entire jurisdictional power grid as the research object. They are no longer like the traditional substation five-protection system that only targets a single device or a single substation. The main body status error prevention system is a universal maintenance-free error prevention system. It will not require maintenance due to abnormal changes in the power grid, nor will it require maintenance due to changes in operating modes, thereby reducing the maintenance workload as much as possible and improving practicality.

[0130] The power grid ontology status anti-error knowledge base disclosed in the present invention only needs to be deployed in the cloud, and can participate in the anti-error verification as an anti-error microservice of the control cloud. There is no need to call on the five-prevention rule formula of the substation, which greatly saves the implementation cost of the cloud-based anti-error verification.
