Description

Technical Field

[0001] The present invention relates to the field of substation noise prediction, and specifically to a method and system for correcting the interference sound field in a substation based on the gradient descent algorithm. Background Technique

[0002] Currently, the calculation of the current substation environmental noise mainly relies on the downwind sound pressure level calculation method under ISO9613-2 and simulation software developed based on this algorithm, such as prediction software like Soundplan and Cadna / A. These software do not consider the acoustic wave interference effect of multiple groups of sound sources when calculating the sound field in the strong interference area inside the substation, resulting in large errors when the software predicts the sound field inside the substation. In some sensitive points at the plant boundary, the error can even reach more than 10 dB, bringing difficulties to the noise control of relevant departments.

[0003] Currently, the sound field calculation method considering the interference effect is mainly LMS VirtualLab represented by the boundary element method. However, in the scenario of calculating the large-range sound field of a substation, it will be limited by problems such as the calculation amount and accuracy, and it is difficult to be applied in practice.

[0004] In the aspect of substation noise prediction, Zhang Guangzhou, Wang Zhonghe and others studied the common noise characteristics and control methods of main equipment in UHV substations. Chen Qingheng, Cao Meigen and others explored the relationship between the vibration characteristics and noise characteristics of transformers and conducted preliminary noise prediction. However, there are complex sound sources such as transformers, reactors, and fans and irregularly arranged buildings inside the substation, making the noise distribution characteristics in the substation plant area much more complex than those of a single sound source. Tian Haoyang and others used the Sound plan analysis software to simulate and optimize the sound environment at the substation plant boundary for this problem. However, the Soundplan software has obvious theoretical defects in dealing with the sound field interference problem and it is difficult to accurately predict the complex acoustic characteristics of the substation plant boundary. Summary of the Invention

[0005] The purpose of the present invention is to address the problem that it is difficult to accurately predict the complex acoustic characteristics of the substation plant boundary, and to propose a method, system, storage medium and electronic device for correcting the interference sound field in a substation based on the gradient descent algorithm. By considering the interference effect of the noise radiated by substation equipment, the substation noise distribution sound field obtained by the calculation method of the downwind sound pressure level based on ISO9613-2 is corrected, thereby improving the prediction accuracy of the substation plant boundary noise.

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] For the noise prediction in a substation, it is essentially a problem of calculating the sound field of the outdoor acoustic environment. In the outdoor acoustic environment, the main sound sources are power equipment such as transformers, reactors, and capacitors. The surface conditions of the substation and other buildings will absorb, reflect, and refract sound waves during the propagation process of sound waves. Finally, the sound pressure at a sensitive point in the substation boundary can be regarded as the energy superposition of the sound waves generated by each sound source after experiencing propagation attenuation at the sensitive point, resulting in a large difference between the results calculated by the prediction software that does not consider the interference factor and the measured value of a sensitive point in the actual situation. Therefore, it is very necessary to consider the interference effect of sound waves.

[0049] As Figure 1 shown, in Embodiment 1, the present application provides a method for correcting the interference sound field in a substation based on the gradient descent algorithm, including the following specific steps:

[0051] b. Using the sound power and frequency in the sound source parameters of the main substation equipment obtained in a as the source strength parameters, establish a substation simulation model, set the corresponding acoustic environment parameters and boundary conditions, and obtain the substation noise distribution sound field;

[0052] c. Consider each main substation equipment as a spherical sound source and calculate the interference radiation sound field of each main substation equipment separately;

[0053] d. Use the phase matching method to correct the phases of the equipment other than the main substation equipment, and calculate the corrected phase interference sound field of each remaining equipment separately;

[0054] e. Using the interference sound field obtained in step d, perform interference correction on the substation noise distribution sound field obtained in step b using the gradient descent algorithm, and obtain the substation boundary noise after the sound field is corrected.

[0055] Further, the vibration parameters and sound pressure data of each equipment in the substation in step a are the surface vibration data and near-field sound pressure data of the transformer below 2 / 3 of the height of the main substation equipment and the surface vibration data and near-field sound pressure data of the reactor below 2 / 3 of the height of the main substation equipment.

[0056] Further, the substation simulation model in step b is a CAD model in DXF format;

[0057] The setting of the corresponding acoustic environment parameters and boundary conditions and obtaining the substation noise distribution sound field includes:

[0058] Configure the layout and geometric space dimensions of each equipment in the substation in the DXF format CAD model, and configure the layout and geometric space dimensions of the buildings in the DXF format CAD model to obtain the configured CAD model;

[0059] Using the ISO9613-2 downwind sound pressure level calculation method, based on the configured CAD model, calculate the substation noise distribution sound field.

[0060] Further, the step of considering each main substation equipment as a spherical sound source and calculating the interference radiation sound field of each main substation equipment separately includes:

[0061] Consider each main substation equipment as a spherical sound source;

[0062] Using the sound source parameters of each main equipment included in the substation as the source strength parameters, calculate the interference radiation sound field of each main substation equipment using the spherical source sound pressure calculation formula.

[0066] Furthermore, the steps of correcting the phases of the remaining devices except the main substation equipment by using the phase matching method and separately calculating the interference sound fields of the corrected phases of each of the remaining devices include:

[0068] Back-calculating the initial phases of the remaining devices based on the minimum error of the corresponding values in the matching results;

[0069] Using the initial phases of all the remaining devices after correction to separately calculate the interference sound fields of each of the remaining devices.

[0070] Furthermore, the calculation formula for obtaining the minimum error is:

[0071]

[0072] where \(p\) i is the combined interference sound field, \(p\) 1i and \(p\) 2i are the interference sound fields of two remaining devices acting alone, \(i = 1\sim M\), and \(M\) is the number of devices.

[0076]

[0077] where \(\theta\) is the weight to be solved, \(\theta'\) is the weight before iteration, \(\alpha\) is the step size of each iteration, and \(j(\theta)\) is the objective function, i.e., the measured sound field value.

[0078] Further, the obtained corrected sound pressure is superimposed on the substation noise distribution obtained by the downwind sound pressure level calculation rule based on ISO9613-2 in step b to obtain data such as the comprehensively corrected substation noise distribution and the noise at the plant boundary.

[0079] Further, the calculation formula for the normalization operation is:

[0080]

[0081] Ap1 is the normalized interference sound field, p 1i and p 2i are the interference sound fields of the other two devices acting alone, i = 1 to M, and M is the number of devices.
