Description

Technical Field

[0001] The present invention relates to the technical field of intelligent monitoring of power transmission lines, and in particular to an intelligent control system for an ultra-high voltage power grid. Background Art

[0002] The safety of transmission towers in ultra-high voltage power grids is extremely important. It is not only related to the stable operation of the power system, but also involves the life safety of operators. The "Electric Power Industry Standard of the People's Republic of China - Operation Regulations for Overhead Transmission Lines" stipulates safety standards such as the skewness of tower crossarms, the curvature of the main material of the tower, the rust of the guy rods, and the tension of the guy wires. However, it is difficult to accurately monitor the above indicators during the operation of the power grid.

[0003] Chinese patent application number CN201911356268.8 discloses a large power grid flexible safety control method and system for power equipment failures, which identifies and extracts the external environment of power grid operation and the state information of power equipment, and obtains key data that characterizes the risk of power grid operation; based on the key data obtained, the power system failure process identification method is used to determine the credible estimate of the power equipment failure process; based on the result of the credible estimate of the power equipment failure process, each failure stage of the power equipment failure process is determined, and for each failure stage, a quantitative evaluation of the power grid stability is performed to determine the active control timing of the failure sequence; the active control timing is used to flexibly implement the active control strategy. The invention evaluates and analyzes each stage in the failure sequence, makes decision-making control measures and corresponding control timing, which is more in line with the actual characteristics of power system failure evolution.

[0004] It can be seen that the monitoring of transmission towers and insulator strings in the prior art is relatively complicated, and most of them are post-maintenance, making it difficult to automatically adjust according to the operating status. Summary of the invention

[0005] To this end, the present invention provides an intelligent control system for an ultra-high voltage power grid and a transmission line guidance method thereof, so as to overcome the problem that the monitoring of transmission towers and insulator strings in the prior art is relatively complicated and mostly performed after-the-fact, and it is difficult to detect the problem that the inductance generated by the line itself during operation may cause structural damage to the insulator string or the transmission tower, thereby reducing the operating safety of the ultra-high voltage power grid.

[0006] To achieve the above object, the present invention provides an intelligent control system for an ultra-high voltage power grid, which is applied to equipment operation monitoring of a transmission tower, and for a single transmission tower, comprises:

[0007] A press test module, which is connected to a corresponding transmission tower and includes two sets of test wheels arranged across the insulator string;

[0008] An information collection module, which is arranged corresponding to and connected to the compression test module, and is used to monitor the amplitude of the test wheel and the angle of the transmission tower;

[0009] An adjuster connected to the transmission tower and the insulator string and provided with corresponding adjustment positions for adjusting the roll angle of the transmission tower and adjusting the height of the end of the insulator string in response to the roll angle;

[0010] A correction module, which is connected to the information acquisition module, and is used to make a preliminary judgment on the posture of the insulator string according to the amplitude of the test wheel, and to determine the correction of the tilt angle of the transmission tower according to the deviation angle of the vertical line of the transmission tower and the adjustment position of the regulator;

[0011] An adjustment module, which is connected to the correction module and the regulator, determines the adjustment of the correction coefficient according to the anti-vibration performance of the insulator string, or adjusts the judgment threshold according to the load of the transmission tower;

[0012] The warning module is connected to the correction module and is used to display the warning information determined by the correction module.

[0013] Furthermore, the information collection module includes:

[0014] A path acquisition unit, which is used to collect the turning radius of the cable corresponding to the insulator string of the transmission line and the height difference between the vertices of the transmission line on the left and right of the insulator string;

[0015] A posture acquisition unit, which is used to acquire the mid-perpendicular deviation angle and the roll angle of each transmission tower;

[0016] A vibration collection unit, which is used to collect the test wheel amplitude and cable vibration amplitude of the transmission line, and determine the test wheel vibration event and the anti-vibration performance of the insulator string;

[0017] Among them, the vibration collection unit records the vibration of the test wheel whose amplitude exceeds the preset amplitude threshold as a test wheel vibration event, and determines the test wheel vibration frequency. The vibration resistance performance corresponding to a test wheel vibration event is related to the test wheel amplitude and the vibration amplitude of each cable of the corresponding test wheel.

[0018] Furthermore, the compression test module makes a preliminary determination of the posture of the insulator string according to the test wheel amplitude, and determines that the posture of the insulator string does not meet the preset standard when the test wheel amplitude exceeds the safety amplitude threshold;

[0019] The safety amplitude threshold is negatively correlated with the deadweight of the insulator string.

[0020] Furthermore, the push test module is also provided with a transmission tower amplitude threshold, and under the condition that the test wheel amplitude exceeds the transmission tower amplitude threshold, it is determined that the insulator string posture does not meet the preset standard, and an alarm is sounded through the warning module, and the push test module stops running;

[0021] The transmission tower amplitude threshold is negatively correlated with the load of the transmission tower and positively correlated with the corresponding cable load.

[0022] Furthermore, the correction module determines the adjustment method of the insulator string posture according to the vibration frequency of the test wheel, wherein:

[0023] If the vibration frequency of the test wheel is lower than the preset frequency threshold, the correction module determines that the reason why the posture of the insulator string does not meet the preset standard is vibration caused by damage to the transmission line, and marks the position where the vibration occurs and issues a warning of transmission line damage through the warning module;

[0024] If the vibration frequency of the test wheel is not lower than the preset frequency threshold, it is determined that the reason why the posture of the insulator string does not meet the preset standard is that the adjustment position of the insulator string does not meet the standard, and the test cycle of the press test module is adjusted according to the difference between the vibration frequency of the press test module and the preset frequency threshold;

[0025] The preset frequency threshold is related to the tension of the transmission line.

[0026] Furthermore, the correction module adjusts the correction adjustment position of the pressing test module according to the difference between the vibration frequency of the test wheel and the preset frequency threshold.

[0027] Furthermore, the correction module corrects the adjustment of the regulator in response to the deviation angle of the vertical line of the transmission tower.

[0028] Furthermore, the correction module determines the correction of the transmission tower by the regulator according to the corrected adjustment position of the press test module.

[0029] Further, the adjustment module determines to adjust the correction coefficient according to the anti-vibration performance of the insulator string, including adjusting the corresponding correction coefficient according to the adjustment coefficient under the condition that the anti-vibration performance value is greater than or equal to a preset anti-vibration performance value;

[0030] The anti-vibration performance is proportional to the stiffness of the overall structure of the insulator string.

[0031] Furthermore, the judgment thresholds set by the adjustment module include a safety amplitude threshold, an insulator string amplitude threshold and a transmission tower amplitude threshold.

[0032] Compared with the prior art, the beneficial effect of the present invention lies in that, by setting an information collection module, the information collection module includes a path collection unit, a posture collection unit and a vibration collection unit, which can collect several parameters of the insulator string of the transmission line, monitor the operation of the equipment along the high-voltage transmission line, and determine the vibration feedback of the transmission line according to the way of pressing the corresponding cable of the insulator string, so as to determine the operating status of the corresponding equipment. While effectively improving the monitoring of the normal operating status of the ultra-high voltage power grid, it avoids the problem of structural damage to the insulator string or the transmission tower due to the inductance generated by the line itself, thereby effectively improving the safety of the operation of the ultra-high voltage power grid.

[0033] Furthermore, the present invention preliminarily determines whether the posture of the insulator string meets the preset standard through the amplitude of the transmission line test wheel. When the posture of the insulator string does not meet the preset standard, different correction methods are adopted for the posture of the insulator string through different comparison results of the amplitude values, so that the posture of the insulator string can be corrected more accurately to the corresponding position for safe operation.

[0034] Furthermore, the present invention determines the reason why the posture of the insulator string does not meet the preset standard through the vibration frequency of the test wheel, and takes corresponding corrective measures according to the different reasons why the posture of the insulator string does not meet the preset standard, which can further improve the accuracy of the insulator string posture adjustment.

[0035] Furthermore, the present invention adjusts the test cycle of the press test module according to the difference between the vibration frequency of the test wheel and the preset frequency threshold, and sets different correction coefficients, which can further optimize the process of self-adjustment of the insulator string posture.

[0036] Furthermore, the present invention adjusts the transmission tower mid-point perpendicular line deviation angle by combining the two factors of the transmission tower mid-point perpendicular line deviation angle and the adjustment position collected by the information collection module, and provides different correction coefficients, so that the posture correction of the transmission tower can be more accurate.

[0037] Furthermore, the present invention adjusts the posture of the push test module under different circumstances by judging the equipment load of the transmission tower, and can further improve the accuracy of the self-adjustment of the posture of the insulator string, thereby enriching the application scenarios.

[0044] See also Figure 1 As shown, it is a structural schematic diagram of the intelligent control system of the ultra-high voltage power grid of the present invention, and the intelligent control system based on the ultra-high voltage power grid includes:

[0045] A press test module, which is connected to a corresponding transmission tower and includes two sets of test wheels arranged across the insulator string;

[0046] The information collection module is arranged corresponding to and connected to the compression test module, and is used to monitor the amplitude of the test wheel and the angle of the transmission tower, and is provided with:

[0050] An adjuster connected to the transmission tower and the insulator string and provided with corresponding adjustment positions for adjusting the roll angle F of the transmission tower and adjusting the end height ΔH of the insulator string in response to the roll angle;

[0051] A correction module, which is connected to the information acquisition module, is used to make a preliminary judgment on the posture of the insulator string according to the amplitude of the test wheel, and to determine the correction of the tilt angle F of the transmission tower according to the deviation angle D of the vertical line of the transmission tower and the adjustment position of the regulator;

[0052] An adjustment module, which is connected to the correction module and the regulator, determines the adjustment of the correction coefficient according to the anti-vibration performance P of the insulator string, or adjusts the judgment threshold according to the load G of the transmission tower;

[0053] The warning module is connected to the correction module and is used to display the warning information determined by the correction module.

[0054] In implementation, the path acquisition unit is provided with an inertial measurement device and a laser rangefinder; the attitude acquisition unit is composed of an inclination sensor; and the vibration acquisition unit is provided with a vibration sensor and a displacement sensor.

[0055] Specifically, the press test module makes a preliminary judgment on the posture of the insulator string according to the test wheel amplitude, and judges that the posture of the insulator string does not meet the preset standard when the test wheel amplitude exceeds the safety amplitude threshold;

[0056] Among them, the safety amplitude threshold is negatively correlated with the deadweight of the insulator string.

[0057] The push test module is also provided with a transmission tower amplitude threshold, and when the test wheel amplitude exceeds the transmission tower amplitude threshold, it is determined that the insulator string posture does not meet the preset standard, and an alarm is issued through the warning module, and the push test module stops running;

[0058] Among them, the transmission tower amplitude threshold is negatively correlated with the load of the transmission tower and positively correlated with the corresponding cable load.

[0059] See also Figure 2 As shown, it is a schematic diagram of the setting of the regulator of an embodiment of the present invention, in which the test wheel is pressed on the transmission line corresponding to the insulator string to monitor the amplitude and frequency of the insulator string;

[0060] Particularly, the test wheel is made of insulating ceramic and can rotate along its own rotation axis.

[0061] The press test module preliminarily determines whether the posture of the insulator string meets the preset standard according to the test wheel amplitude A, where the test wheel amplitude A is obtained by the vibration collection unit, including:

[0062] If A<A1, it is determined that the posture of the insulator string meets the preset standard;

[0063] If A1≤A<A2, it is determined that the posture of the insulator string does not meet the preset standard, and the reason why the posture of the insulator string does not meet the preset standard is determined according to the vibration frequency E of the test wheel;

[0064] If A2≤A<A3, it is determined that the posture of the insulator string does not meet the preset standard, and the correction method of the regulator is determined according to the deviation angle D of the vertical line of the transmission tower and the adjustment position S;

[0065] If A≥A3, it is determined that the posture of the insulator string does not meet the preset standard, and an alarm is triggered through the warning module to stop the operation of the press test module.

[0066] In the embodiment of the present invention, the vibration collection unit is preset with judgment thresholds for the test wheel amplitude including: a safety amplitude threshold A1, an insulator string amplitude threshold A2, and a transmission tower amplitude threshold A3, and 1<A1<A2<A3<10.

[0067] Generally, in the circuit, A1 is generally set to 10mm, A2 is generally set to 15mm, and A3 is generally set to 17mm.

[0068] It is understandable that the above names are only set to distinguish the values ​​and have no other specific meanings.

[0069] When the insulator string vibrates, the amplitude is less than 10mm, which means that the vibration of the insulator string is natural vibration and can operate safely. If the amplitude is 10mm-15mm when the insulator string vibrates, the insulator string will be at risk of damage, and the insulator string needs to be stabilized. If the amplitude is 15mm-17mm when the insulator string vibrates, the vibration of the insulator string is a precursor to vibration caused by changes in current, and there will be a higher risk of damage.

[0070] In the embodiment of the present invention, when the insulator string vibrates, it can be judged whether the posture of the insulator string meets the standard according to the magnitude of the test wheel amplitude. If it does not meet the standard, different correction methods are adopted for the posture of the insulator string according to the different intervals in which the test wheel amplitude is located, so that the press test module can be corrected to a guiding posture that meets the standard more accurately. Those skilled in the art can adjust the safety amplitude threshold A1, the insulator string amplitude threshold A2, and the transmission tower amplitude threshold A3 according to actual conditions.

[0071] Specifically, the vibration of the test wheel with an amplitude exceeding a preset amplitude threshold A0 is recorded as a test wheel vibration event. The number of test wheel vibration events within a fixed time period T is the test wheel vibration frequency E. Conventionally, A0 is set to 10 mm.

[0072] In the embodiment of the present invention, if the test wheel amplitude collected by the vibration collection unit is greater than the preset amplitude threshold A0, it is recorded as a test wheel vibration event. Assuming that the time period T is 1 minute, there are 5 test wheel vibration events during the period, and the test wheel vibration frequency is 5 times / minute. Those skilled in the art can adjust the preset amplitude threshold A0 according to actual conditions.

[0073] Specifically, the reasons why the insulator string posture does not meet the preset standard according to the test wheel vibration frequency E include:

[0074] If E<E0, it is determined that the reason why the insulator string posture does not meet the preset standard is the vibration caused by the damage of the transmission line, and the position where the vibration occurs is marked and a warning of the damage of the transmission line is issued through the warning module;

[0075] If E≥E0, it is determined that the reason why the insulator string posture does not meet the preset standard is that the adjustment position S does not meet the standard and the test cycle S of the press test module is adjusted according to the difference ΔE between the test wheel vibration frequency E and the preset frequency threshold E0.

[0076] In particular, if the vibration frequency E of the press test module is different, the reasons why the insulator string posture does not meet the preset standard are different. Different countermeasures are taken according to the different reasons for the non-standard posture of the insulator string. The press test module can adjust the guide posture more accurately.

[0077] In practice, the adjustment can be performed through a traction insulator string, which is a conventional method and will not be described in detail here.

[0078] Specifically, adjusting the test cycle of the press test module according to the difference ΔE between the vibration frequency E of the test wheel and the preset frequency threshold E0 includes:

[0079] If ΔE<ΔE1, the adjustment position S is corrected by the first tilt correction coefficient;

[0080] If ΔE1≤ΔE<ΔE2, the adjustment position S is corrected by the second tilt correction coefficient;

[0081] If ΔE≥ΔE2, the adjustment position S is corrected using the third tilt correction coefficient.

[0082] In the embodiment of the present invention, the higher the vibration frequency E of the test wheel, the higher the test cycle of the press test module, so the first tilt correction coefficient is smaller than the second tilt correction coefficient and smaller than the third tilt correction coefficient. In different situations, different tilt correction coefficients are adopted to avoid overcorrection. Those skilled in the art can adjust the preset frequency threshold E0 according to actual conditions.

[0083] In the embodiment of the present invention, the correction module is preset with a preset frequency threshold E0, a first relative difference ΔE1, and a second relative difference ΔE2, wherein ΔE1<ΔE2. The preset frequency threshold E0 is set to 1 time / hour, and the frequency of the transmission line construction test wheel vibration event is within a safe range under the condition that the preset frequency threshold E0 is set to 1 time / hour.

[0084] In the embodiment of the present invention, the first preset frequency difference is 5, and the second preset frequency difference is 10. The higher the vibration frequency E of the insulator string, the higher the test cycle of the press test module, so the corresponding tilt correction coefficient should be larger, and correspondingly, the first tilt correction coefficient < the second tilt correction coefficient < the third tilt correction coefficient, the first tilt correction coefficient is 0.9, the second tilt correction coefficient is 0.7, and the third tilt correction coefficient is 0.5.

[0085] Specifically, the correction of the regulator is determined according to the deviation angle D of the vertical line of the transmission tower, including:

[0086] If D<D1, the transmission tower tilt angle F is corrected by the first angle correction coefficient;

[0087] If D1≤D<D2, the transmission tower tilt angle F is corrected by the second angle correction coefficient;

[0088] If D≥D2, the transmission tower tilt angle F is corrected using the third angle correction coefficient.

[0089] Specifically, the correction method of the regulator is determined according to the adjustment position S, including:

[0090] If S<S1, the tilt angle F of the transmission tower is corrected by the first center of gravity offset;

[0091] If S1≤S<S2, the transmission tower tilt angle F is corrected by the second center of gravity offset;

[0092] If S≥S2, the tilt angle F of the transmission tower is corrected by the second center of gravity offset.

[0093] In the embodiment of the present invention, D1<D2, the value of the first preset deviation angle is, the value of the second preset deviation angle is, the insulator string is in a relatively safe range under the condition that the deviation angle of the vertical line of the transmission tower is 0-3°. The larger the deviation angle of the vertical line of the transmission tower of the insulator string is, the larger the corresponding correction coefficient is. Correspondingly, the first angle correction coefficient is less than the second angle correction coefficient and the third angle correction coefficient, and the value range is 0-1, the first angle correction coefficient is 0.3, the second angle correction coefficient is 0.5, and the third angle correction coefficient is 0.7.

[0094] When correcting the roll angle of the transmission tower, the vibration of the insulator string causes periodic impulses in the corresponding direction of the transmission tower. Correspondingly, in order to stabilize the transmission tower, the center of gravity of the transmission tower is adjusted by using a counterweight. The first center of gravity offset is less than the second center of gravity offset and the third center of gravity offset. The value range is 0-1. The first center of gravity offset is 0.3m / △H, the second center of gravity offset is 0.5m / △H, and the third center of gravity offset is 0.7m / △H.

[0095] In the embodiment of the present invention, the transmission tower midline deviation angle is adjusted by combining the transmission tower midline deviation angle and the adjustment position collected by the information collection module, and different correction coefficients are provided, so that the correction of the insulator string posture can be more accurate.

[0096] Specifically, the adjustment module determines the adjustment of the correction coefficient according to the anti-vibration performance value P of the insulator string, and the correction coefficient includes the first tilt correction coefficient, the second tilt correction coefficient, the third tilt correction coefficient and the first angle correction coefficient, the second angle correction coefficient, the third angle correction coefficient and the first center of gravity offset, the second center of gravity offset, and the third center of gravity offset.

[0097] Specifically, the adjustment module determines to adjust the correction coefficient according to the anti-vibration performance of the insulator string, including adjusting the corresponding correction coefficient according to the adjustment coefficient under the condition that the anti-vibration performance value is greater than or equal to the preset anti-vibration performance value;

[0098] Among them, the anti-vibration performance is proportional to the stiffness of the overall structure of the insulator string.

[0099] Specifically, the adjustment module determines the adjustment of the determination threshold according to the load G of the transmission tower, and the determination threshold includes the safety amplitude threshold A1, the insulator string amplitude threshold A2, and the transmission tower amplitude threshold A3.

[0100] Specifically, the adjustment methods include:

[0101] If G<G1, the determination threshold is adjusted by the first adjustment coefficient;

[0102] If G1≤G<G2, the determination threshold is adjusted by the second adjustment coefficient;

[0103] If G≥G2, the determination threshold is adjusted using the third adjustment coefficient.

[0104] Conventionally, 0<G1<G2<1, the first preset equipment load G1 is 0.5 tons, the second preset equipment load is 1 ton, and the load of the insulator string is within the safe range within 0.5 tons.

[0105] In particular, the above values ​​are adjusted accordingly according to the design load of the insulator string in practice, and the corresponding judgment threshold values ​​should also be different.

[0106] The greater the load on the transmission tower, the greater the corresponding judgment threshold value should be, where the first adjustment coefficient is less than the second adjustment coefficient and the third adjustment coefficient. Usually, the first adjustment coefficient is 1.5, the second adjustment coefficient is 1.3, and the third adjustment coefficient is 0.8. When applied, the above coefficients can be multiplied by the corresponding judgment thresholds, which will not be repeated here.

[0107] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.

[0108] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
