Description

Technical Field

[0001] The present invention relates to the field of one-key sequential control of a substation, and in particular to a one-key sequential control error prevention method, system and device for a GIS substation. Background Art

[0002] GIS equipment (gas insulated metal-enclosed switchgear) is composed of circuit breakers, busbars, disconnectors, voltage transformers, current transformers, lightning arresters, bushings, grounding switches and other components. As the primary equipment in the substation, it plays a key role in improving the efficiency and quality of power grid operation.

[0003] During the switching operation of a conventional substation, according to the requirements of the substation operation procedures, after each step of opening or closing operation, it is necessary to confirm whether the mechanical opening and closing indication of the GIS equipment being operated is consistent with the background signal. If they are consistent, the next operation can be carried out, which is "double confirmation". The reason for this is that the GIS equipment may have transmission jams during the opening and closing operation, resulting in the failure of the contact to move in place, or the three-phase mechanical linkage structure may have interphase connecting rods break / fall off during the operation process, resulting in the inconsistency between the driven phase and the mechanism phase state, etc. These faults cannot be discovered through the electrical signals sent by the auxiliary switches in the mechanism. If the mechanical indications at the main body are not reviewed and the switching operation is continued blindly, serious accidents such as tripping or discharge of the GIS equipment will occur.

[0004] At present, the logic judgment of programmed operation of substation only judges the opening and closing status of the GIS knife switch through the single electrical indication of the GIS knife switch. When the mechanical position of the GIS knife switch is not in place, it will cause serious safety risks. In serious cases, it will lead to serious safety accidents such as live earth switch, thus limiting the promotion of "unmanned operation" and programmed operation of substations. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a one-key sequential control error prevention method, system and device for a GIS substation, so as to solve at least one technical problem in the background technology.

[0006] The technical solution of the present invention to solve the above technical problem is as follows: a one-key sequential control error prevention method for a GIS substation, comprising the following steps:

[0007] S1, after issuing a one-button sequential control command to the GIS substation, collect the real-time status of the switch of each GIS device in the GIS substation and the power parameters on the transmission line connected to each of the GIS devices;

[0008] S2, processing the power parameters on the transmission lines connected to each of the GIS devices, and obtaining the corresponding theoretical states of the switches of each of the GIS devices;

[0009] S3, comparing the theoretical state of the knife switch of each GIS device with the real-time state of the knife switch, and obtaining a comparison result of the knife switch state of each GIS device;

[0010] S4, analyzing the comparison results of the switch states of the various GIS devices to obtain the one-button sequential control error prevention type of the GIS substation;

[0011] S5, implementing corresponding error prevention operations according to the one-key sequential control error prevention type of the GIS substation.

[0012] Based on the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, in S1, the power parameters include line voltage and line current.

[0018] Furthermore, the classifier includes at least a convolution layer, an activation function layer, a pooling layer and a fully connected layer; the classifier is used to analyze the comprehensive change characteristics of the transmission lines connected to each of the GIS devices, specifically:

[0019] Using the convolution layer to perform a convolution operation on the comprehensive change characteristics of the transmission lines connected to each of the GIS devices, to obtain the state change characteristics of the transmission lines connected to each of the GIS devices;

[0020] Extracting a feature fusion sequence from state change features of power transmission lines connected to each of the GIS devices using the activation function layer;

[0021] Using the pooling layer to perform a pooling operation on the feature fusion sequence on the power transmission line connected to each of the GIS devices, to obtain the pooling features on the power transmission line connected to each of the GIS devices;

[0022] The fully connected layer is used to perform a fully connected operation on the pooled features on the transmission lines connected to each of the GIS devices to obtain the theoretical state of the knife switch of each of the GIS devices.

[0023] Further, in said S3:

[0024] If the theoretical state of the knife switch of the GIS device is consistent with the real-time state of the knife switch, the comparison result of the knife switch state of the GIS device is that the knife switch state has not changed;

[0025] If the theoretical state of the knife switch of the GIS device is inconsistent with the real-time state of the knife switch, the comparison result of the knife switch state of the GIS device is that the knife switch state has changed.

[0026] Furthermore, before S4, the following steps are also included:

[0030] The response degree of each GIS device to the one-key sequential control instruction is analyzed to obtain the one-key sequential control error prevention type of the GIS substation.

[0031] Further, in the process of comparing the switch state comparison result of each GIS device with the switch state change simulation result:

[0032] If the comparison result of the switch state of the GIS device is exactly the same as the simulation result of the switch state change, the response degree of the GIS device to the one-key sequential control instruction is full response;

[0033] If the comparison result of the switch state of the GIS device is partially the same as the simulation result of the switch state change, then the response degree of the GIS device to the one-key sequential control instruction is partial response;

[0034] If the comparison result of the switch state of the GIS device is completely different from the simulation result of the switch state change, the GIS device will not respond to the one-key sequential control instruction at all.

[0035] Based on the above-mentioned one-key sequential control error prevention method for a GIS substation, the present invention also provides a one-key sequential control error prevention system for a GIS substation.

[0046] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0047] like Figure 1 As shown, a one-key sequential control error prevention method for a GIS substation includes the following steps:

[0048] S1, after issuing a one-button sequential control command to the GIS substation, collect the real-time status of the switch of each GIS device in the GIS substation and the power parameters on the transmission line connected to each of the GIS devices;

[0049] S2, processing the power parameters on the transmission lines connected to each of the GIS devices, and obtaining the corresponding theoretical states of the switches of each of the GIS devices;

[0050] S3, comparing the theoretical state of the knife switch of each GIS device with the real-time state of the knife switch, and obtaining a comparison result of the knife switch state of each GIS device;

[0051] S4, analyzing the comparison results of the switch states of the various GIS devices to obtain the one-button sequential control error prevention type of the GIS substation;

[0052] S5, implementing corresponding error prevention operations according to the one-key sequential control error prevention type of the GIS substation.

[0053] In this specific embodiment: the power parameters include line voltage and line current.

[0054] In this specific embodiment: S2 is specifically:

[0055] Determine, based on the line voltage on the transmission line connected to each of the GIS devices, a voltage variation characteristic characterizing the degree of voltage variation on the transmission line connected to each of the GIS devices; and determine, based on the line current on the transmission line connected to each of the GIS devices, a current variation characteristic characterizing the degree of current variation on the transmission line connected to each of the GIS devices;

[0056] The voltage change characteristics and the current change characteristics on the transmission lines connected to each of the GIS devices are integrated to obtain the comprehensive change characteristics on the transmission lines connected to each of the GIS devices;

[0057] The classifier is used to analyze the comprehensive change characteristics of the transmission lines connected to each of the GIS devices, and the corresponding theoretical states of the switches of each of the GIS devices are obtained.

[0058] Specifically, the line voltage includes the positive line voltage and the negative line voltage; the line current includes the positive line current and the negative line current; the formula for determining the voltage change characteristic is: U=k(U + -U - ), the formula for determining the current change characteristics is: I=k(I + -I - ), where U and I are voltage change characteristics and current change characteristics, respectively. + , U - ,I + ,I - They are positive line voltage, negative line voltage, positive line current, and negative line current respectively. k is a characteristic variation parameter, which is generally taken as .

[0059] The voltage change characteristics and the current change characteristics on the transmission lines connected to each of the GIS devices are integrated, that is, the voltage change characteristics and the current change characteristics on the transmission lines connected to each of the GIS devices are multiplied to obtain the comprehensive change characteristics on the transmission lines connected to each of the GIS devices. The comprehensive change characteristics reflect the output energy changes of the GIS devices.

[0060] More specifically, in step S2, the power transmission line connected to the GIS device includes an incoming line side and an outgoing line side, and the line voltage and line current of the incoming line side are input into the Berelon model for processing to predict the line voltage and line current of the outgoing line side, and obtain the theoretical value of the line voltage and the theoretical value of the line current measured by the outgoing line;

[0061] ;

[0062] in, and Indicates the incoming line side The line voltage and line current at the moment, represents the Berelon model, and Indicates the output side Theoretical values ​​of line voltage and line current at the moment;

[0063] The line voltage and theoretical value of the line voltage on the outgoing line side are subjected to feature residual extraction processing to determine the voltage change characteristics that characterize the degree of voltage change on the transmission line connected to each of the GIS devices; the line current and theoretical value of the line current on the outgoing line side are subjected to feature residual extraction processing to determine the current change characteristics that characterize the degree of current change on the transmission line connected to each of the GIS devices; wherein the feature residual extraction formula is:

[0064] ;

[0065] for or ; for or ; Indicates The systematic error of time and obeys N )’s normal distribution; for The residual between

[0066] The voltage or current change characteristics are expressed as:

[0067] ;

[0068] Indicates the voltage or current change characteristics.

[0069] The present invention adopts the Berelon model to predict the theoretical value of the power parameter on the outgoing line side, which greatly simplifies the calculation method while ensuring accuracy; the system error is fully considered in the process of feature residual extraction, which can avoid the influence of the system error on the voltage and current change characteristics, thereby improving the feature extraction accuracy.

[0070] The voltage change characteristics and the current change characteristics on the transmission lines connected to each of the GIS devices are integrated to obtain the comprehensive change characteristics on the transmission lines connected to each of the GIS devices;

[0071] The fusion formula is:

[0072] ;

[0073] in, Indicates the voltage change characteristics, Indicates the current variation characteristics, and is the fusion weight, and .

[0074] The fusion weight is determined by the device properties of the GIS device; if the power parameter changes caused by the GIS device action are mainly voltage changes, then Value greater than If the power parameter change caused by the GIS equipment operation is mainly the change of current, then Value less than The use of fusion weights can more significantly highlight the change characteristics, thereby improving the subsequent analysis results and obtaining a more correct knife switch theoretical state.

[0075] In this specific embodiment: the classifier includes at least a convolution layer, an activation function layer, a pooling layer and a fully connected layer; the classifier is used to analyze the comprehensive change characteristics of the transmission lines connected to each of the GIS devices, specifically:

[0076] Using the convolution layer to perform a convolution operation on the comprehensive change characteristics of the transmission lines connected to each of the GIS devices, to obtain the state change characteristics of the transmission lines connected to each of the GIS devices;

[0077] Extracting a feature fusion sequence from state change features of power transmission lines connected to each of the GIS devices using the activation function layer;

[0078] Using the pooling layer to perform a pooling operation on the feature fusion sequence on the power transmission line connected to each of the GIS devices, to obtain the pooling features on the power transmission line connected to each of the GIS devices;

[0079] The fully connected layer is used to perform a fully connected operation on the pooled features on the transmission lines connected to each of the GIS devices to obtain the theoretical state of the knife switch of each of the GIS devices.

[0080] Specifically, in the classifier, the activation function in the activation function layer is a tanh activation function. The method of the present invention can accurately and quickly determine the theoretical state of the knife switch of the GIS device according to the power parameters on the transmission line by using a neural network-based classifier, that is, the knife switch state that should appear when the GIS device responds to a one-key sequential control instruction.

[0081] In this specific embodiment: in S3:

[0082] If the theoretical state of the knife switch of the GIS device is consistent with the real-time state of the knife switch, the comparison result of the knife switch state of the GIS device is that the knife switch state has not changed;

[0083] If the theoretical state of the knife switch of the GIS device is inconsistent with the real-time state of the knife switch, the comparison result of the knife switch state of the GIS device is that the knife switch state has changed.

[0084] The real-time status of the knife switch of the GIS device is the status of the knife switch fed back after the GIS device executes opening and closing after responding to the one-button sequential control instruction. The theoretical status of the knife switch reflects the actual current and voltage control results on the power grid, which is the real status of the knife switch. By comparing the theoretical status of the knife switch that should appear when the GIS device responds to the one-button sequential control instruction with the actual real-time status of the knife switch, the change of the knife switch status before and after the GIS device responds to the one-button sequential control instruction can be determined, and it can be judged whether there is a situation where the switch is not closed in place.

[0085] In this specific embodiment: before S4, the following steps are also included:

[0086] The one-button sequential control instruction is simulated based on the GIS substation model to obtain the simulation results of the switch status changes of each GIS device in the GIS substation.

[0087] Since errors or equipment damage are unavoidable during the operation of the GIS substation, the calculated theoretical state of the knife switch of the GIS equipment is affected by the errors. In order to eliminate the influence of errors or equipment damage, the present invention uses a GIS substation model to simulate the one-key sequential control instruction to obtain the simulation result of the knife switch state change of the GIS equipment, and uses this simulation result as a reference for subsequent comparison, thereby improving the accuracy of error prevention.

[0088] In this specific embodiment: S4 is specifically:

[0089] Comparing the switch state comparison result of each GIS device with the switch state change simulation result to determine the response degree of each GIS device to the one-key sequential control instruction;

[0090] The response degree of each GIS device to the one-key sequential control instruction is analyzed to obtain the one-key sequential control error prevention type of the GIS substation.

[0091] In this specific embodiment, in the process of comparing the switch state comparison result of each GIS device with the switch state change simulation result:

[0092] If the comparison result of the switch state of the GIS device is exactly the same as the simulation result of the switch state change, the response degree of the GIS device to the one-key sequential control instruction is full response;

[0093] If the comparison result of the switch state of the GIS device is partially the same as the simulation result of the switch state change, then the response degree of the GIS device to the one-key sequential control instruction is partial response;

[0094] If the comparison result of the switch state of the GIS device is completely different from the simulation result of the switch state change, the GIS device will not respond to the one-key sequential control instruction at all.

[0095] Specifically, if the GIS device fully responds to the one-button sequential control instruction, it means that the control logic of the one-button sequential control instruction for the GIS device is completely correct, and there is no need to prevent misoperation; if the GIS device partially responds to the one-button sequential control instruction, it means that the mechanical position of the knife switch of the GIS device is not in place, and corresponding measures are taken to repair the GIS device; if the GIS device does not respond to the one-button sequential control instruction at all, it means that the control logic of the one-button sequential control instruction for the GIS device is wrong, and corresponding measures are taken to verify the one-button sequential control instruction.

[0096] Based on the above-mentioned one-key sequential control error prevention method for a GIS substation, the present invention also provides a one-key sequential control error prevention system for a GIS substation.

[0097] like Figure 2 As shown, a one-key sequential control and error prevention system for GIS substation includes the following modules:

[0098] The power parameter acquisition module is used to collect the real-time status of the switches of each GIS device in the GIS substation and the power parameters on the transmission lines connected to each GIS device after issuing a one-key sequential control instruction to the GIS substation;

[0099] A knife switch theoretical state analysis module, which is used to process the power parameters on the transmission line connected to each of the GIS devices, and obtain the knife switch theoretical state of each of the GIS devices;

[0100] A switch status comparison module, which is used to compare the switch theoretical status of each GIS device with the switch real-time status, and obtain the switch status comparison result of each GIS device;

[0101] A one-button sequential control error prevention type analysis module, which is used to analyze the comparison results of the switch states of each GIS device to obtain the one-button sequential control error prevention type of the GIS substation;

[0102] The anti-misoperation module is used to implement corresponding anti-misoperation according to the one-key sequential control anti-misoperation type of the GIS substation.

[0103] The specific functions of each module in the one-key sequential control and error prevention system for a GIS substation of the present invention refer to the specific steps of the one-key sequential control and error prevention method for a GIS substation of the present invention, which will not be repeated here.

[0104] Based on the above-mentioned one-key sequential control error prevention method for a GIS substation, the present invention also provides a one-key sequential control error prevention device for a GIS substation.

[0105] A one-key sequential control error prevention device for a GIS substation comprises a processor, a memory and a computer program stored in the memory. When the computer program is executed by the processor, the one-key sequential control error prevention method for a GIS substation as described above is implemented.

[0106] The present invention provides a one-key sequential control error prevention method, system and device for a GIS substation. The method analyzes and processes the power parameters on the transmission lines connected to each of the GIS devices to obtain the theoretical state of the knife switch of each of the GIS devices. The knife switch state comparison result is obtained by comparing the theoretical state of the knife switch with the real-time state of the knife switch. Compared with a single electrical indication to judge the opening and closing state of the knife switch, the judgment result is more accurate and the error rate is lower. In addition, the present invention obtains the one-key sequential control error prevention type according to the knife switch state comparison result and performs corresponding error prevention operations, which can save the manual on-site confirmation link and can effectively improve the efficiency of the substation one-key sequential control operation.
