Description

Technical Field

[0001] The present invention belongs to the field of electric power and relates to intelligent sensor technology, specifically a multi-modal collaborative control method and system based on the side expansion inner cone casing of an inflatable cabinet. Background Art

[0002] The existing modal collaborative control method has the following specific defects when collaboratively controlling the inner cone sleeve of the side expansion of the inflatable cabinet:

[0003] 1. The existing modal collaborative control method cannot monitor the current harmonics of the sample inner cone bushing during the bushing electrical indicator monitoring period to obtain the periodic current harmonic index value, nor can it monitor the voltage harmonics of the inner cone bushing during the bushing electrical indicator monitoring period to obtain the periodic voltage harmonic index value. This easily leads to a lack of accuracy in power indicator monitoring, making it difficult to ensure the accuracy of collaborative control.

[0004] 2. The existing modal collaborative control method cannot monitor the temperature indicators of the cone sleeve in the sample during the sleeve temperature monitoring period, and cannot divide the cone sleeve in the sample into different environments based on the monitoring results. Therefore, it is impossible to adopt targeted control methods for sleeves in different ambient temperatures, which easily leads to a lack of targeted control process.

[0097] Step S142: performing periodic voltage harmonic monitoring on the sample inner cone bushing in the Y1 voltage monitoring sub-period, and obtaining a Y1 voltage harmonic monitoring index value according to the monitoring result;

[0098] The step S142 further includes the following specific steps:

[0099] In the Y1 voltage monitoring sub-cycle, the voltage harmonics appearing in the cone bushing of the sample are recorded using a voltage harmonic analyzer to obtain periodic voltage harmonics. The harmonic amplitude corresponding to each periodic voltage harmonic is obtained to obtain multiple voltage harmonic amplitudes.

[0100] Compare the numerical values ​​of the multiple voltage harmonic amplitudes obtained, mark the voltage harmonic amplitude with the largest value as the cycle peak voltage harmonic amplitude, mark the harmonic amplitude with the smallest value as the cycle valley harmonic amplitude, and mark the numerical interval formed by the cycle peak voltage harmonic amplitude and the cycle valley voltage harmonic amplitude as the Y1 cycle voltage harmonic peak valley interval;

Divide the bushing electrical indicator monitoring cycle into multiple voltage monitoring sub-cycles of equal duration, and further record the voltage harmonics in detail within each sub-cycle. By obtaining the amplitude corresponding to the voltage harmonics in each cycle, the intensity of the harmonics at different times is clearly defined. This meticulous division and recording method can fully capture the dynamic changes of voltage harmonics throughout the entire monitoring cycle, and not miss any harmonic details that may affect the bushing electrical performance.

[0114] 2. The periodic voltage harmonics index, as a quantitative indicator, provides a clear standard for evaluating the stability of bushing electrical performance. Based on the index value, combined with relevant industry standards or empirical thresholds, personnel can objectively and accurately evaluate the bushing's electrical performance stability. This quantitative evaluation method avoids arbitrary subjective judgment and improves the reliability and accuracy of the evaluation results.

[0115] 3. Long-term monitoring and analysis of periodic voltage harmonics can also provide a reference for bushing design and optimization. By studying the changing trends of bushing voltage harmonics under different time periods and operating conditions, it is possible to identify potential deficiencies in the bushing design or manufacturing process. For example, if the bushing voltage harmonics are found to be generally high under certain operating conditions, it may be necessary to optimize the bushing structure, materials, or electrical parameters to improve its harmonic interference resistance and overall electrical performance, thereby extending the bushing's service life and enhancing the operational reliability of the power system.

[0128] Step S32: if the periodic current harmonic index value is within the current harmonic reference interval, and the periodic voltage harmonic index value is within the voltage harmonic reference interval, the sample inner cone bushing is classified as a bushing with normal electrical indicators;

[0129] Step S33: if the periodic current harmonic index value is not within the current harmonic reference interval, and the periodic voltage harmonic index value is within the voltage harmonic reference interval, the sample inner cone bushing is classified as a bushing with abnormal electrical index;

[0130] Step S34: if the periodic current harmonic index value is within the current harmonic reference interval, and the periodic voltage harmonic index value is not within the voltage harmonic reference interval, the sample inner cone bushing is classified as a bushing with abnormal electrical index;

[0131] Step S35: if the periodic current harmonic index value is not within the current harmonic reference interval, and the periodic voltage harmonic index value is not within the voltage harmonic reference interval, the sample inner cone bushing is classified as a bushing with abnormal electrical index;

[0132] Step S36: Coordinated control of bushings with abnormal electrical indicators based on bushing temperature type classification data;

[0133] The step S36 further includes the following specific steps: if the bushing with abnormal electrical indicators is a bushing in the first temperature environment, lowering the internal ambient temperature of the bushing until the bushing cycle temperature value is within the bushing cycle temperature reference range;

[0134] If the bushing with abnormal electrical indicators is the bushing in the second temperature environment, an abnormal bushing operation warning will be issued;

[0135] If the bushing with abnormal electrical indicators is a bushing in the third temperature environment, the internal ambient temperature of the bushing is increased until the bushing cycle temperature value is within the bushing cycle temperature reference range.

[0136] In this application, if a corresponding calculation formula appears, the above calculation formula is dimensionless and its numerical calculation is performed. The weight coefficient, proportional coefficient and other coefficients in the formula are set to a result value obtained by quantifying each parameter. Regarding the size of the weight coefficient and the proportional coefficient, as long as it does not affect the proportional relationship between the parameter and the result value, it is acceptable.
