In severe cases, it can lead to line breakage, tower collapse, and short circuits, resulting in widespread power outages and economic losses. Therefore, research on galloping based on real-world transmission lines is crucial for maintaining the safety and stability of power systems.

[0003] At present, for dancing simulation tests, as described in the Chinese invention patent with application number "202010795449.7", dancing is usually simulated in a passive manner, which limits the overall control of the test, is not conducive to maintaining the accuracy of the real line dancing simulation, and greatly reduces the effectiveness of the simulation results.

[0007] When the frame mechanism is mounted, the eccentric drive mechanism is activated to output the eccentric rotational force to drive the counterweight mechanism to move up and down;

[0008] The vibration frequency of the wire is collected in real time, and a deviation value Δf between the vibration frequency and a preset target frequency is calculated using a fuzzy PID algorithm to determine whether the Δf is within a preset range;

[0009] If so, maintaining the rotational speed of the eccentric drive mechanism;

[0039] In the first aspect, an embodiment of the present invention provides a device for quantitatively simulating dancing parameters based on a true-type circuit, comprising a frame mechanism 1, an eccentric drive mechanism 2, a regulating mechanism 3 and a counterweight mechanism 4. The frame mechanism 1 is used to be hung below the wire 5, and the eccentric drive mechanism 2 and the regulating mechanism 3 are both installed on the frame mechanism 1. The eccentric drive mechanism 2 is used to output an eccentric rotational force around the horizontal direction, and the counterweight mechanism 4 is hung below the output end of the eccentric drive mechanism 2 and is used to adjust the counterweight mass; the regulating mechanism 3 is electrically connected to the eccentric drive mechanism 2 and is used to: when the frame mechanism 1 is hung, start the eccentric drive mechanism 2 and output an eccentric rotational force to drive the counterweight mechanism 4 to move up and down; collect the vibration frequency of the wire 5 in real time, calculate the deviation value Δf between the vibration frequency and the preset target frequency through the fuzzy PID algorithm, and judge whether Δf is within the preset range; if so, maintain the rotation speed of the eccentric drive mechanism 2; if not, adjust the rotation speed of the eccentric drive mechanism 2 according to Δf, and repeat the calculation of Δf and the judgment of whether it is within the preset range.

[0040] Specifically, the counterweight mechanism 4 can adjust the weight by changing the combined counterweight modules, and can also be a magnetic counterweight structure, which changes the weight by adjusting the magnetic force; the frame mechanism 1 can be lifted to the conductor 5 by an insulating lifting device for hanging, and the frame mechanism 1 can be set to a modular structure, which is convenient for hanging with different types of conductors 5 and realizing quick disassembly and assembly.

[0041] In this optional embodiment, if Figure 1As shown, a frame mechanism 1, an eccentric drive mechanism 2, a regulating mechanism 3 and a counterweight mechanism 4 are set to form a dancing parameter quantitative simulation device based on a real-type circuit, wherein the frame mechanism 1 can be hung under the wire 5, and the eccentric drive mechanism 2 and the regulating mechanism 3 are both installed on the frame mechanism 1, thereby ensuring the installation stability of the dancing parameter quantitative simulation device based on the real-type circuit on the wire 5 of the real-type circuit, and the eccentric drive mechanism 2 can output an eccentric rotational force around the horizontal direction, and the counterweight mechanism 4 is hung under the output end of the eccentric drive mechanism 2, so that the counterweight mechanism 4 can be driven up and down by the eccentric rotational force, and then a vibration force is generated, and finally the vibration force is transmitted to the wire 5 through the frame mechanism 1, so as to realize active excitation of the wire 5, so that the wire 5 can actively dance and realize dancing simulation; on this basis, the regulating mechanism 3 is electrically connected to the eccentric drive mechanism 2 to realize quantitative control of the eccentric rotational force output by the eccentric drive mechanism 2, and the counterweight mechanism 4 can adjust the counterweight mass to realize the matching use of wires 5 of different models. In the same way, when the frame mechanism 1 is hung and the counterweight mechanism 4 completes the mass adjustment, the control mechanism 3 can start the eccentric drive mechanism 2, output the eccentric rotational force, drive the counterweight mechanism 4 to move up and down, and complete the initial active excitation of the dancing. Then the control mechanism 3 can collect the vibration frequency of the conductor 5 in real time through the fluctuation frequency of the dancing parameter quantitative simulation device of the entire real line, and then calculate the deviation value Δf between the vibration frequency and the preset target frequency through the fuzzy PID algorithm to determine whether Δf is within the preset range. If so, it means that the vibration frequency of the conductor 5 during dancing meets the requirements, and the rotation speed of the eccentric drive mechanism 2 can continue to be maintained. If not, the rotation speed of the eccentric drive mechanism 2 can be adjusted according to Δf, and the calculation of Δf and the judgment of whether it is within the preset range are repeated until the vibration frequency of the conductor 5 during dancing meets the requirements, thereby reducing the steady-state error of the vibration frequency, realizing precise control of the vibration frequency of the conductor 5 dancing, and then realizing quantitative control of the real line dancing parameters, effectively improving the accuracy of the real line dancing simulation.

[0042] It should be noted that, in this embodiment, the deviation value Δf is calculated by the following formula:

[0043] Δf=f trr -f meas ,

[0044] Among them, f trr is the preset target frequency value, f meas is the actual measured vibration frequency of the conductor 5. A positive value of Δf indicates that the measured frequency is lower than the target and the output of the eccentric drive mechanism 2 needs to be increased. A negative value of Δf indicates that the measured frequency is higher than the target and the output of the eccentric drive mechanism 2 needs to be decreased.

[0045] Optionally, the frame mechanism 1, the eccentric drive mechanism 2, the regulating mechanism 3 and the counterweight mechanism 4 are set as working modules, and two working modules are set, and the two working modules are respectively hung at the two ends of the span of the conductor 5; the regulating mechanism 3 is also used to: when the simulated dancing waveform of the conductor 5 is set to half a sine wave, adjust the phase difference between the eccentric drive mechanisms 2 of the two working modules to 0°; when the simulated dancing waveform of the conductor 5 is set to a sine wave, adjust the phase difference between the eccentric drive mechanisms 2 of the two working modules to 180°.

[0046] In this optional embodiment, in order to achieve precise control of the dancing waveform of the conductor 5, the frame mechanism 1, the eccentric drive mechanism 2, the regulating mechanism 3 and the counterweight mechanism 4 are set as working modules, and at the same time, two working modules are set. The two working modules can be respectively mounted on the two ends of the span of the conductor 5. The regulating mechanism 3 between the two working modules can realize wireless communication through 4G communication and other methods to maintain the coordinated work of the two working modules, reduce the dancing phase difference and frequency difference generated during work, and maintain the stability of the dancing waveform; among them, when the simulated dancing waveform of the conductor 5 is set to half a sine wave, the two working modules can be adjusted respectively by the two regulating mechanisms 3. The phase difference between the eccentric drive mechanisms 2 of the two working modules is 0°, so that the synchronous fluctuations at both ends of the wire 5 are achieved through the same-phase excitation at both ends of the span of the wire 5, so that the dancing waveform of the wire 5 is a single half-wave, that is, half a sine wave. Correspondingly, when the simulated dancing waveform of the wire 5 is set to a sine wave, the phase difference between the eccentric drive mechanisms 2 of the two working modules is adjusted to 180°, so that the staggered fluctuations at both ends of the wire 5 are achieved through the reverse phase excitation at both ends of the span of the wire 5, so that the dancing waveform of the wire 5 is a double half-wave, that is, a sine wave, thereby achieving precise control of the dancing waveform of the wire 5 and improving the accuracy of the dancing simulation of the wire 5.

[0047] Optionally, the eccentric drive mechanism 2 includes a rotating drive member 21, a gear structure 22 and an eccentric member 23, the rotating drive member 21 is driven and connected to the eccentric member 23 through the gear structure 22, and the counterweight mechanism 4 is hung under the eccentric member 23; the frame mechanism 1 includes a protective shell 11, which covers the rotating drive member 21 and the gear structure 22.

One end of the rocker arm 235 is rotationally connected to the edge of the turntable 232 through the rocker shaft 234, and the other end of the rocker arm 235 is rotationally connected to the counterweight mechanism 4.

[0053] In this optional embodiment, if Figures 1 to 3 As shown, a turntable washer 231, a turntable 232, a synchronization pin 233, a rocker shaft 234 and a rocker arm 235 are provided to form an eccentric member 23, wherein the turntable 232 is mounted on the rotation shaft 223, and the turntable washer 231 is placed between the synchronization gear 222 and the turntable 232, and the synchronization pin 233 is connected to the turntable 232 and the synchronization gear 222 respectively, so that the rotation of the synchronization gear 222 can drive the turntable 232 to rotate synchronously through the connection of the synchronization pin 233, and the synchronization gear 222 and the turntable 232 can be separated by the turntable washer 231. Open, avoid interference between the two, and ensure the stability of the turntable 232 when outputting rotational force; on this basis, one end of the rocker arm 235 is rotatably connected to the edge of the turntable 232 through the rocker arm shaft 234, and the other end of the rocker arm 235 is rotatably connected to the counterweight mechanism 4, so that the rocker arm 235 and the turntable 232 are stably articulated through the rocker arm shaft 234, and an eccentric structure is formed by the rocker arm 235 and the turntable 232, so that the turntable 232 can drive the other end of the rocker arm 235 to fluctuate up and down when it rotates, and then drive the counterweight mechanism 4 to fluctuate up and down, actively exciting vibration.
