The grounding detection value is numerically compared with the preset grounding detection threshold. If the grounding detection value exceeds the preset grounding detection threshold, a grounding warning signal is generated; if the grounding detection value does not exceed the preset grounding detection threshold, a grounding safety signal is generated.

[0008] Furthermore, the specific operation process of the isolation device reliability detection module includes: The average failure interval time and average repair time of the corresponding isolation equipment are collected, and the average failure interval time and the average repair time are numerically calculated to obtain the isolation performance value, the isolation performance values ​​of all isolation equipment in the operating line are averaged to obtain the isolation performance value, the isolation equipment whose isolation performance value exceeds the preset isolation performance threshold is marked as the isolation-optimized equipment, and the ratio of the number of isolation-optimized equipment in the operating line to the total number of isolation equipment is calculated to obtain the isolation-optimized detection value, and the isolation performance value with the smallest numerical value is marked as the isolation low amplitude value; The isolation reliability coefficient is obtained by numerically calculating the isolation performance value, the isolation excellent detection value and the isolation low amplitude value, and the isolation reliability coefficient is numerically compared with the preset isolation reliability coefficient threshold. If the isolation reliability coefficient exceeds the preset isolation reliability coefficient threshold, an isolation high reliability signal is generated; if the isolation reliability coefficient does not exceed the preset isolation reliability coefficient threshold, an isolation low reliability signal is generated.

The operation environment analysis value, the line detection value, the grounding detection value and the isolation reliability coefficient are numerically calculated to obtain an operation risk comprehensive assessment value. The operation risk comprehensive assessment value is numerically compared with the preset operation risk comprehensive assessment threshold. If the operation risk comprehensive assessment value exceeds the preset operation risk comprehensive assessment threshold, a high-risk operation signal is generated; if the operation risk comprehensive assessment value does not exceed the preset operation risk comprehensive assessment threshold, a low-risk operation signal is generated.

[0011] Furthermore, the specific analysis process of the operating environment monitoring module is as follows: The ambient temperature and humidity of the environment where the operation line is located are collected, and the deviation value between the ambient temperature and the preset standard value of the suitable operating environment temperature is marked as the operating temperature value. Similarly, the operating humidity value is obtained; and the ultraviolet detection value, wind detection value and rain and snow detection value of the environment where the operation line is located are collected, and the height of the operation line is marked as the operating height detection value; The operating environmental analysis value is obtained by numerically calculating the operating temperature value, operating humidity value, ultraviolet detection value, wind detection value, rain and snow detection value and operating high detection value.

[0012] Furthermore, the specific analysis process of the line detection analysis module is as follows: The average voltage of the operating line in a unit time is collected and marked as the voltage detection value, the difference between the maximum voltage and the minimum voltage in the operating line in a unit time is collected and marked as the voltage stability value, and the difference between the maximum current and the minimum current in the operating line in a unit time is marked as the current stability value; The amount of electricity consumed by the operating line per unit time is obtained and marked as the line energy consumption value, and the real-time temperatures of several locations on the operating line are averaged to obtain the line temperature detection value. The line detection value is obtained by numerically calculating the voltage detection value, voltage stability value, current stability value, line energy consumption value and line temperature detection value.

[0013] Furthermore, the comprehensive assessment module for operational risk is communicatively connected to the operational arrangement analysis module.

If an arrangement risk signal is generated, it is sent to the risk control end via the server. The risk control end issues an early warning when receiving the arrangement risk signal.

[0014] Furthermore, the specific analysis process of the job arrangement analysis module is as follows: The total operation time of the corresponding operators in the historical stage for the distribution line operation is collected and marked as the line operation condition value, and the number of wrong operations made by the corresponding operators in the distribution line operation process in the historical stage is marked as the line operation error value; The heart rate of the operator is calculated by difference with the median of the preset suitable heart rate range and the absolute value is taken to obtain the heart rate deviation value; the body temperature of the operator is calculated by difference with the median of the preset suitable body temperature range and the absolute value is taken to obtain the body temperature deviation value; The arrangement risk analysis value is obtained by numerically calculating the line operation condition value, line operation error value, heart rate deviation value and body temperature deviation value, and the arrangement risk analysis value is numerically compared with the preset arrangement risk analysis threshold value.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings; Figure 1 This is a system block diagram of Embodiment 1 of the present invention; Figure 2 This is a system block diagram of Embodiment 2 of the present invention. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1: Figure 1 As shown, the present invention proposes an operation risk management and control system suitable for the safety of distribution line operations, including a server, a grounding risk detection module, an isolation equipment reliability detection module, an operation risk comprehensive assessment module and a risk management and control terminal; the server obtains the distribution line that needs to be operated, and marks the corresponding distribution line as an operation line; The grounding risk detection module detects and analyzes the grounding risk of the operating line, generates a grounding safety signal or a grounding warning signal through analysis, and sends the grounding warning signal to the risk control end through the server. The risk control end issues a warning when receiving the grounding warning signal, and can reasonably analyze and accurately judge the grounding safety of the operating line. When the grounding warning signal is generated, the distribution line operation is temporarily not performed and corresponding improvement measures are taken to avoid distribution line operation accidents caused by grounding hazards. The specific operation process of the grounding risk detection module is as follows: The real-time temperature and real-time humidity of the environment in which the grounding device of the operating line is located are collected, and the real-time temperature and real-time humidity are numerically compared with the preset real-time temperature threshold and the preset real-time humidity threshold, respectively. If the real-time temperature or real-time humidity exceeds the corresponding preset threshold, it is judged that the grounding device is in a damaged state; it should be noted that high temperature and humid environment are likely to accelerate the aging and corrosion process of the insulating material in the grounding device, resulting in a decrease in the grounding performance of the grounding device; The total duration of the grounding device in the damaged state in the historical stage is obtained and marked as the damaged detection value, the single duration of each time the grounding device is in the damaged state in the historical stage is collected, and the number of occurrences of the single duration of the damaged state in the historical stage exceeding the preset single duration threshold is marked as the high damage frequency, and the grounding resistance value of the grounding device of the operating line is collected; wherein, the larger the value of the grounding resistance value, the more likely it is to cause poor grounding, increasing the risk of electric shock; By formula The damaged detection value LS, the high loss frequency LP and the grounding resistance value LK are numerically calculated to obtain the grounding detection value LZ, wherein a1, a2 and a3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the grounding detection value LZ is, the worse the grounding condition of the operating line is, and the greater the potential safety hazard of the distribution line operation is; The grounding detection value LZ is numerically compared with the preset grounding detection threshold. If the grounding detection value LZ exceeds the preset grounding detection threshold, it indicates that the grounding condition of the operating line is poor and the operating safety hazard of the distribution line is large, then a grounding warning signal is generated; if the grounding detection value LZ does not exceed the preset grounding detection threshold, it indicates that the grounding condition of the operating line is good, then a grounding safety signal is generated.

[0019] The grounding risk detection module sends the grounding safety signal to the isolation equipment reliability detection module. After receiving the grounding safety signal, the isolation equipment reliability detection module analyzes the reliability performance of the isolation equipment (such as circuit breakers, disconnectors, etc.) corresponding to the operating line, generates an isolation high reliability signal or an isolation low reliability signal through analysis, and sends the isolation low reliability signal to the risk control end via the server; When the risk control end receives the isolation low reliability signal, it issues an early warning. When the isolation low reliability signal is generated, the distribution line operation is temporarily not performed and corresponding improvement measures are taken to ensure that the isolation equipment of the distribution line can work reliably and that the fault point can be isolated in time in the event of a fault to prevent the accident from expanding. The specific operation process of the isolation equipment reliability detection module is as follows: The mean time between failures and mean time to repair of the corresponding isolation equipment are collected, where the mean time between failures refers to the average working time between two consecutive failures of the isolation equipment under specified conditions and within a specified time, also known as the mean time between failures. The higher the value of the mean time between failures, the higher the reliability of the isolation equipment, that is, the longer the isolation equipment can continue to work between two failures; the mean time to repair refers to the average recovery time when the isolation equipment changes from a faulty state to a working state. A lower mean time to repair means that the isolation equipment can recover faster when a failure occurs; The isolation performance value GX is obtained by numerically calculating the mean time between failures GY and the mean time to repair GM through the formula GX=up1*GY+up2 / GM, wherein up1 and up2 are preset proportional coefficients, and up2>up1>0; and the larger the value of the isolation performance value GX, the better the isolation performance of the corresponding isolation device; The isolation performance values ​​of all isolation devices in the operation line are averaged to obtain the isolation performance value, the isolation devices whose isolation performance values ​​exceed the preset isolation performance threshold are marked as excellent isolation devices, and the number of excellent isolation devices in the operation line is calculated by ratio to the total number of isolation devices to obtain the excellent isolation detection value, and the isolation performance value with the smallest value is marked as the isolation low amplitude value; The isolation reliability coefficient GK is obtained by numerically calculating the isolation performance value GW, the isolation detection value GF and the isolation low amplitude GR through the formula GK=hp2*GF+(hp1*GW+hp3*GR) / 2, where hp1, hp2 and hp3 are preset proportional coefficients, hp2>hp1>hp3>0; and the larger the value of the isolation reliability coefficient GK, the smaller the isolation risk of the operating line; The isolation reliability coefficient GK is numerically compared with the preset isolation reliability coefficient threshold. If the isolation reliability coefficient GK exceeds the preset isolation reliability coefficient threshold, it indicates that the isolation risk of the operating line is relatively small, and an isolation high reliability signal is generated; if the isolation reliability coefficient GK does not exceed the preset isolation reliability coefficient threshold, it indicates that the isolation risk of the operating line is relatively large, and an isolation low reliability signal is generated.

[0020] The isolation equipment reliability detection module sends the isolation high reliability signal to the operation risk comprehensive assessment module. When receiving the isolation high reliability signal, the operation risk comprehensive assessment module conducts a comprehensive assessment of the operation risk status of the operation line and generates an operation high risk signal or an operation low risk signal through analysis; The high-risk signal or low-risk signal of the operation is sent to the risk control end through the server. When the risk control end receives the high-risk signal of the operation, it issues an early warning. When receiving the corresponding early warning, it decides whether to temporarily not perform the corresponding distribution line operation, or to perform the distribution line operation cautiously and increase the supervision of the operation process according to the needs, so as to further ensure the safety of the distribution line operation and the high degree of intelligence. The specific operation process of the comprehensive assessment module of operation risk is as follows: Obtain the operating environment analysis value of the operating line environment and the line detection value of the operating line, as well as the grounding detection value and isolation reliability coefficient corresponding to the operating line; By formula The operation environment analysis value YH, the line detection value YX, the grounding detection value LZ and the isolation reliability coefficient GK are numerically calculated to obtain the operation risk comprehensive evaluation value YR; wherein, b1, b2, b3, b4 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the operation risk comprehensive evaluation value YR is, the greater the overall operation risk for the operation line is; The operation risk comprehensive evaluation value YR is numerically compared with the preset operation risk comprehensive evaluation threshold. If the operation risk comprehensive evaluation value YR exceeds the preset operation risk comprehensive evaluation threshold, it indicates that the operation risk for the operation line is relatively large, and a high-risk operation signal is generated; if the operation risk comprehensive evaluation value YR does not exceed the preset operation risk comprehensive evaluation threshold, it indicates that the operation risk for the operation line is relatively small, and a low-risk operation signal is generated.

[0021] Specifically, the operation risk comprehensive assessment module is connected to the operation environment monitoring module and the line detection and analysis module through communication. The operation environment monitoring module monitors and analyzes the environment of the operation line, obtains the operation environment analysis value through analysis, and sends the operation environment analysis value to the operation risk comprehensive assessment module, which can not only accurately feedback the operation environment risk of the operation line, but also provide data support for the analysis process of the operation risk comprehensive assessment module to ensure the accuracy of its analysis results; The line detection and analysis module analyzes the line condition of the operating line, obtains the line detection value through analysis, and sends the line detection value to the comprehensive assessment module of operation risk. It can not only accurately feedback the line operation risk of the operating line, but also provide data support for the analysis process of the comprehensive assessment module of operation risk, and further ensure the accuracy of its analysis results.

[0022] In addition, the specific analysis process of the working environment monitoring module is as follows: the ambient temperature and ambient humidity of the working line are collected, and the deviation between the ambient temperature and the preset standard value of the suitable working environment temperature is marked as the working temperature value, and the working humidity value is obtained in the same way; and the ultraviolet detection value (i.e., the data value of the intensity of ultraviolet radiation), wind detection value (i.e., the data value of the wind speed) and rain and snow detection value (i.e., the data value of the amount of rain and snow) of the working line are collected, and the height of the working line is marked as the working height detection value; The operating environment value YH is obtained by numerically calculating the operating temperature value SF, the operating humidity value SX, the ultraviolet detection value SW, the wind force detection value SN, the rain and snow detection value SQ and the operating high detection value SD through the formula YH=(t1*SF+t2*SX+t3*SW+t4*SN+t5*SQ+t6*SD) / 6; among them, t1, t2, t3, t4, t5 and t6 are preset proportional coefficients whose values ​​are greater than zero, and the larger the numerical value of the operating environment value YH, the greater the operating environment risk of the operating line.

[0023] Furthermore, the specific analysis process of the line detection analysis module is as follows: the average voltage of the operating line in a unit time is collected and marked as the voltage detection value, and the difference between the maximum voltage and the minimum voltage in the operating line in a unit time is collected and marked as the voltage stability value, and the difference between the maximum current and the minimum current in the operating line in a unit time is marked as the current stability value; wherein, the larger the values ​​of the voltage stability value and the current stability value are, the more unstable the power of the operating line is; The power consumed by the operating line per unit time is obtained and marked as the line energy consumption value, and the real-time temperatures of several locations on the operating line are averaged to obtain the line temperature detection value; the larger the line energy consumption value and the line temperature detection value, the greater the safety hazard of the operating line; By formula The voltage detection value FY, the voltage stability value FK, the current stability value FM, the line energy consumption value FS and the line temperature detection value FG are numerically calculated to obtain the line detection value YX; wherein, q1, q2, q3, q4, q5 are preset proportional coefficients whose values ​​are greater than zero, and the larger the numerical value of the line detection value YX, the greater the line safety hazard of the operating line.

[0024] Embodiment 2: Figure 2 As shown, the difference between this embodiment and the first embodiment is that the operation risk comprehensive assessment module is connected to the operation arrangement analysis module in communication. When a high-risk operation signal is generated, the operation arrangement analysis module obtains the operator who is ready to operate on the operation line, analyzes the rationality of the operation arrangement of the corresponding operator, and determines whether to generate an arrangement risk signal through analysis. If an arrangement risk signal is generated, it is sent to the risk control end via the server; When the risk control end receives the arrangement risk signal, it issues an early warning to suspend the corresponding distribution line operation or replace the operator, thereby further ensuring the operation safety of the distribution line; the specific analysis process of the operation arrangement analysis module is as follows: The total operation time of the corresponding operators in the historical stage for the distribution line operation is collected and marked as the line operation condition value, and the number of wrong operations made by the corresponding operators in the distribution line operation process in the historical stage is marked as the line operation error value; The heart rate and body temperature of the corresponding operator are collected, the heart rate of the operator is calculated to be different from the median of the preset suitable heart rate range, and the absolute value is taken to obtain the heart rate deviation value, and the body temperature of the operator is calculated to be different from the median of the preset suitable body temperature range, and the absolute value is taken to obtain the body temperature deviation value; By formula The line operation condition value XS, the line operation error value XD, the heart rate deviation value XF and the body temperature deviation value XN are numerically calculated to obtain the arrangement risk analysis value XK, wherein g1, g2, g3 and g4 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the arrangement risk analysis value XK is, the greater the risk of the corresponding operator to perform the operation; The arrangement risk analysis value XK is numerically compared with the preset arrangement risk analysis threshold. If the arrangement risk analysis value XK exceeds the preset arrangement risk analysis threshold, it indicates that the risk of the corresponding operator performing the operation is relatively high, and the operator needs to be replaced or the operation needs to be suspended in time, then an arrangement risk signal is generated.

[0025] The working principle of the present invention: when in use, the grounding risk of the operating line is detected and analyzed through the grounding risk detection module, which can reasonably analyze and accurately judge the grounding safety of the operating line. When generating a grounding safety signal, the reliability performance of the isolation equipment corresponding to the operating line is analyzed through the isolation equipment reliability detection module. When a grounding warning signal or an isolation low reliability signal is generated, the distribution line operation is temporarily not performed and corresponding improvement measures are taken, thereby avoiding distribution line operation accidents caused by grounding hazards and isolation performance hazards, improving the safety of distribution line operations, and when generating an isolation high reliability signal, the operation risk status of the operation line is comprehensively evaluated through the operation risk comprehensive assessment module. Through analysis, a high-risk operation signal or a low-risk operation signal is generated. When a high-risk operation signal is generated, the distribution line operation is temporarily not performed or performed cautiously and the operation process supervision is increased, further ensuring the safety of distribution line operations, and the degree of intelligence is high.

The operation risk management system applicable to the safety of power distribution line operations according to claim 8, characterized in that: The specific analysis process of the job arrangement analysis module is as follows: The total operation time of the corresponding operators in the historical stage for the distribution line operation is collected and marked as the line operation condition value, and the number of wrong operations made by the corresponding operators in the distribution line operation process in the historical stage is marked as the line operation error value; The heart rate of the operator is calculated by difference with the median of the preset suitable heart rate range and the absolute value is taken to obtain the heart rate deviation value; the body temperature of the operator is calculated by difference with the median of the preset suitable body temperature range and the absolute value is taken to obtain the body temperature deviation value; The arrangement risk analysis value is obtained by numerically calculating the line operation condition value, line operation error value, heart rate deviation value and body temperature deviation value, and the arrangement risk analysis value is numerically compared with the preset arrangement risk analysis threshold value. If the arrangement risk analysis value exceeds the preset arrangement risk analysis threshold value, an arrangement risk signal is generated.
