Description

Technical Field

[0001] This application belongs to the field of grounding resistance monitoring, and specifically relates to a grounding resistance monitoring and early warning system. Background Technology

[0002] As the safety cornerstone of various projects such as power systems, communication base stations, and industrial facilities, the grounding grid's grounding resistance value directly affects the operational stability of equipment and the safety of personnel. Oxidation and corrosion of the grounding circuit itself, loose connections, or the surrounding environment can all cause the resistance value to gradually deteriorate. When the grounding resistance exceeds the safety threshold, overvoltages generated by lightning strikes, equipment leakage, etc., cannot be discharged in time, which can easily lead to serious accidents such as equipment insulation breakdown, signal interference, or even electric shock to personnel. Therefore, real-time and accurate monitoring of the grounding resistance of each circuit of the grounding grid, and early warning management, have become core requirements for ensuring the safe operation of various infrastructures. Current grounding resistance monitoring technology relies solely on comparing the current resistance value with a threshold. If the current grounding resistance is within the safe threshold but may exceed the installation threshold later, it is difficult to predict potential risks in advance and provide a warning buffer time. Furthermore, the monitoring timeliness is insufficient. The fixed-cycle monitoring mode cannot capture anomalies in a timely manner when grounding resistance changes abruptly or environmental parameters change drastically. During the stable operation phase of the equipment, there is a problem of wasted monitoring resources. After an anomaly is detected, manual intervention is required, which cannot ensure the normal operation of the grounding network in a timely manner, resulting in low response efficiency. Summary of the Invention

[0003] To address the aforementioned problems and technical deficiencies, this application adopts the following technical solution: a grounding resistance monitoring and early warning system, comprising: The excitation measurement module is deployed and installed on each grounding loop of the grounding grid, and sends multiple excitation measurement signals of different frequencies to generate induced current in the grounding loop and grounding electrode; The monitoring and sensing module is deployed and buried in the soil around the grounding electrode to form a monitoring network that matches the grounding grid. It receives induced current and collects the ambient temperature and humidity of the surrounding soil. The early warning management module is used to acquire the induced current, ambient temperature and humidity received or collected by the monitoring and sensing module, calculate the grounding resistance value of the grounding loop, make a health judgment on the grounding resistance based on the calculation results, and take corresponding early warning measures to manage the grounding resistance in the grounding grid.

[0004] Preferably, the grounding resistance value of the calculated grounding loop is the induced current received first. The induced current generates an induced voltage in the monitoring and sensing module, and the original measured resistance is calculated based on the induced voltage and the resistance of the monitoring and sensing module itself. R m =U0 / I c -R0 Among them, R m is the original measured resistance, U0 is the induced voltage generated by the monitoring circuit in the monitoring and sensing module, I c is the current value generated by the monitoring circuit of the monitoring and sensing module itself after receiving the induced current, and R0 is the resistance of the monitoring and sensing module itself; Then, it is calculated by combining the ambient temperature and humidity collected at the same moment as the received induced current to obtain the actual resistance value; The calculation formula for the actual resistance value is as follows: R c =R m *[1 + k1*(T - T0) + k2*(H - H0) + k3*(ρ - ρ0) / ρ0 + k4*I c Among them, R c is the actual resistance value, T is the soil temperature, T0 is the soil reference temperature, α is, H is the soil humidity, H0 is the soil reference humidity, ρ is the soil resistivity, ρ0 is the soil reference resistivity, and k1, k2, k3, and k4 are the influence correction coefficients of soil temperature, soil humidity, soil resistivity, and current respectively.

[0005] Furthermore, the soil reference temperature, soil reference humidity, and soil reference resistivity are all the averages of the current monitoring and sensing module under the same usage cycle and the same usage environmental conditions.

[0006] Furthermore, the excitation measurement module sends excitation measurement signals using a dynamic monitoring period, and the calculation formula for the dynamic monitoring period is as follows: T m =T b *[k5 / 丨R c -R t 丨 + k6 / ΔE] ΔE 2 =ΔT 2 +ΔH 2 +Δρ 2 Among them, T m is the time interval between the next sending of the excitation measurement signal and the current sending of the excitation measurement signal, which is used as the dynamic monitoring period, T b is the preset reference monitoring period, R t ​Here, ΔE is the preset safe resistance threshold, ΔT is the soil temperature change rate, representing the difference between the soil temperature collected this time and the soil temperature collected last time, ΔH is the soil moisture change rate, representing the difference between the soil moisture collected this time and the soil moisture collected last time, Δρ is the soil resistivity change rate, representing the difference between the soil resistivity collected this time and the soil resistivity collected last time, k5 is the resistance health weighting factor, k6 is the environmental impact weighting factor, and k5+k6=1.

[0007] Furthermore, the health assessment of the grounding resistance is performed by assessing the current actual resistance value, the trend of grounding resistance change, and the predicted resistance value after the target monitoring period. If the condition does not meet the health strategy, an alarm signal is issued. If the condition meets the health strategy, a trend prediction is then performed based on the current actual resistance value.

[0008] Furthermore, the trend prediction and predicted resistance value are calculated based on the current actual resistance value to determine the resistance value for the target monitoring period. The formula for calculating the predicted resistance value is as follows: R p (Δt) i =R c +∑(ΔR) c / T m *Δt i ) Δt i =T b *i Among them, R p (Δt) i Let ΔR be the predicted resistance after the i-th reference monitoring period. c ΔR is the difference between the actual resistance value calculated this time and the actual resistance value calculated last time. c / T m Let Δt be the current rate of change of resistance, and let it be the trend of change. i To achieve the i-th baseline monitoring period T b The time spent, i=1,2,...n.

[0009] Furthermore, the health assessment includes: The actual resistance value R c With safety resistance threshold R t Perform the calculation; if R c >R t If so, an emergency warning will be issued; Otherwise, set the safety resistance threshold R. t Input R into the formula for calculating the predicted resistance value. p (Δt) i =R tCalculate the current grounding resistance to reach the safe resistance threshold R. t Remaining time Δt i ; Based on the remaining time Δt i The health index of the target grounding loop is calculated using the following formula: HI=α*Δt i +β*R c +γ*ΔE Where HI is the health index, α is the time dynamic weight, β is the resistance dynamic weight, and γ is the environmental dynamic weight, which is dynamically adjusted according to the dynamic monitoring cycle, and α+β+γ=1. If the health index is lower than the health threshold, an emergency warning will be issued.

[0010] Preferably, the management of the grounding resistance in the grounding grid includes: The excitation measurement module is equipped with an adjustable rheostat, which is adjusted according to the grounding resistance R of the grounding loop in which the excitation measurement module is located. c and remaining time Δt i The adjustable rheostat in the excitation measurement module is wirelessly controlled and adjusted to control and adjust the grounding resistance of the grounding loop.

[0012] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the contents of a grounding resistance monitoring and early warning system as described above.

[0013] Compared to existing technologies, the beneficial effects of this application are as follows: (1) This application adjusts the monitoring frequency by dynamically monitoring the cycle, which can ensure the timeliness of data by high-frequency acquisition when the resistance is close to the safety threshold or when the environment fluctuates drastically, and can also ensure the output of low-frequency monitoring and excitation measurement signals when the environment is stable and the resistance does not fluctuate, thereby reducing sensor energy consumption and improving service life. (2) This application not only makes a health judgment on the current resistance value, but also predicts the resistance value after the target period based on the current resistance change rate through trend prediction. It can not only provide an alarm after the anomaly occurs, but also provide an early warning before the anomaly occurs. By calculating the remaining time required to reach the safety threshold, it provides valuable decision-making and response time for maintenance personnel and realizes predictive maintenance. (3) This application takes into account the remaining time for resistance to meet the standard, the current resistance value and the rate of change of the environment, and adapts to the judgment needs under different monitoring cycles through dynamic weight adjustment. It conducts multi-factor assessment, which can issue an emergency warning when the resistance exceeds the standard, and can also identify potential risks in advance, leaving sufficient response time for the replacement or maintenance of the grounding grid.
