Not only can it be ensured that the seismic performance of any scheme selected from the optimal solution set is at least pass, avoiding the risk that the optimization result is mathematically optimal but physically unsafe, but also the optimization algorithm only performs in-depth analysis and iteration on qualified schemes, which can greatly shorten the time to find the optimal solution set.

Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of GIS overall machine layout and design, and particularly relates to a GIS overall machine layout and seismic performance integrated design method and system. BACKGROUND

[0002] The gas insulated metal enclosed switchgear is widely used in the transformer substation due to its compact structure, high reliability, and non-environmental influence, etc. However, the GIS device is usually composed of multiple functional modules connected through flanges and conductors, and the overall structure is complex, the mass distribution is uneven, and the gravity center is high, which leads to relatively weak seismic performance. In the earthquake-prone area, the damage of the GIS device will lead to the paralysis of the entire transformer substation and cause losses.

[0003] At present, the layout design and seismic performance evaluation of the GIS device are usually two relatively independent processes. The designer first performs the spatial layout of the device according to the electrical main wiring and site conditions to form a preliminary design scheme, and then the structural engineer performs the seismic checking on the scheme, usually adopts the finite element analysis method, and if the seismic performance does not meet the requirements, the designer needs to return to modify the layout or increase the local structural strengthening measures, and then perform a new round of checking. This serial design mode not only has a long design cycle, but also depends on the personal experience of the engineer to a great extent, lacks a systematic guidance method, and is easy to lead to material waste or insufficient seismic performance.

[0004] To solve the above problems, the application designs a GIS overall machine layout and seismic performance integrated design method and system. SUMMARY

[0018] S34, based on the obtained anti-seismic performance index, the installation quality of the device is evaluated and analyzed;

[0019] S35, if the installation quality evaluation analysis result is lower than the preset value, it is determined that the layout is unqualified, the layout scheme is automatically excluded, otherwise if the installation quality evaluation analysis result is higher than the preset value, it is determined that the layout is qualified, the layout scheme is retained, and the anti-seismic performance index under the layout scheme is also retained.

Based on the embodiments in the present application, all the other embodiments obtained by those ordinarily skilled in the art without creative work fall within the scope of the present application.

[0036] Embodiment 1

[0037] To solve the technical problems in the background art, the present application provides a preferred embodiment: as shown in the figure, the GIS whole machine layout and anti-seismic performance integrated design method comprises the following specific steps: Figures 1-2

[0038] S1, a parameterized three-dimensional model component library containing GIS standard modules is established;

[0039] S2, according to the electrical main wiring and site conditions, the models in the three-dimensional model component library are called for assembly to generate an initial GIS whole machine three-dimensional model;

[0040] S3, finite element modeling and anti-seismic performance simulation analysis are carried out based on the initial GIS whole machine three-dimensional model;

[0041] S4, by changing the key layout parameters and carrying out multiple simulations, a mapping relationship model between the key layout parameters and the anti-seismic performance indicators is established, the key layout parameters including device leg span, cylinder support position, height difference between adjacent modules, telescopic joint arrangement position and quantity;

[0042] S5, a multi-objective optimization model is constructed with the optimal anti-seismic performance and compact layout as the target, and the key layout parameters are optimized and solved based on the mapping relationship model constructed in S4 to obtain an optimal solution set;

[0043] S6, a final scheme is selected from the optimal solution set, and the three-dimensional model is automatically updated and the design results are output.

[0044] It should be noted that the constraint conditions of the multi-objective optimization model include electrical safety distance, operation and maintenance space requirement and site boundary limitation, the multi-objective optimization algorithm used in step S5 is NSGA-II, MOPSO or multi-objective genetic algorithm, and NSGA-II, MOPSO or multi-objective genetic algorithm are prior art, which will not be described in detail here.

[0045] ​The advantages of the embodiment over the prior art are: firstly, the originally fragmented layout design and seismic analysis are integrated in one process, through automated simulation and optimization, greatly reducing manual intervention and iteration times, significantly improving design efficiency and shortening research and development cycle; secondly, the seismic performance is introduced as an optimization target at the initial design stage, through systematic parameter optimization, a more reasonable layout and better seismic performance design scheme can be obtained, which improves the reliability of the layout scheme from the source; then, through the established parameterized component library and mapping relationship model, the experience of design experts is accumulated, reducing the dependence of the design process on personal experience, which is conducive to knowledge inheritance and standardized design; finally, through multi-objective optimization, the best balance point between seismic performance and layout compactness and other contradictory targets can be found, realizing global optimal or approximate optimal design, avoiding the blindness and conservatism of traditional design methods.

[0046] Further, the parameterized three-dimensional model component library includes a circuit breaker, a disconnector, a mutual inductor and a bus cylinder, and the geometric size, mass attribute and material attribute are parameterized driven.

[0047] In an optional embodiment, the parameterized three-dimensional model component library includes a circuit breaker, a disconnector, a mutual inductor and a bus cylinder, and the geometric size, mass attribute and material attribute are parameterized driven.

[0048] In an optional embodiment, the finite element modeling and seismic performance simulation analysis based on the initial GIS whole machine three-dimensional model include the following steps:

[0049] S31, importing the GIS whole machine three-dimensional model into the finite element environment, and assigning material attributes to each component based on the pre-defined material library, then automatically defining the contact relationship between components according to the key layout parameters and applying fixed constraints and gravity loads to the equipment;

[0050] S32, reading multiple seismic waves from the seismic wave library, and applying seismic excitation to the GIS equipment in the form of three-axis acceleration;

[0051] S33, obtaining the equivalent stress and displacement of the key parts of the GIS under seismic excitation mode;

[0052] S34, evaluating and analyzing the installation quality of the equipment based on the obtained seismic performance indicators;

[0053] S35, if the installation quality evaluation and analysis result is lower than the preset value, it is determined that the layout is unqualified, and the layout scheme is automatically excluded, otherwise if the installation quality evaluation and analysis result is higher than the preset value, it is determined that the layout is qualified, and the layout scheme is retained, and the seismic performance indicators under the layout scheme are also retained.

[0054] It needs to be explained: the multi-objective optimization algorithm of step S5 needs to be calculated hundreds of times, each iteration corresponds to a set of parameters and a design scheme, through step S34 and step S35, unqualified schemes that cannot meet the seismic demand can be pre-screened, which can prevent the optimization algorithm from blindly evaluating all parameter combinations, including bad schemes that obviously do not meet the basic seismic safety requirements, and can avoid these unqualified schemes occupying the population position of the optimization algorithm, leading to algorithm searching in invalid area, wasting a lot of computing resources, through step S35, it is automatically excluded in advance, the optimization algorithm only analyzes and iterates qualified schemes, which can greatly shorten the time to find the optimal solution set, the optimal seismic performance is a relative concept, and an absolute safety standard must be met in engineering, and the preset value in step S34 is the safety bottom line.

[0055] In an optional embodiment, the evaluation and analysis of the installation quality of the equipment based on the obtained seismic performance indicators includes the following steps:

[0056] S341, based on the equivalent stress of each key position obtained, the stress anomaly of the GIS is evaluated and analyzed, and the stress anomaly calculation formula is: wherein n is the number of key positions, Wi is the equivalent stress of the i-th key position, is the maximum equivalent stress of the i-th key position:

[0057] S342, based on the displacement of each key position obtained, the vibration anomaly of the GIS is evaluated and analyzed, and the vibration anomaly calculation formula is: wherein is the displacement deviation of the i-th key position at t, Rim is the maximum value of the safety displacement deviation of the i-th key position at t, T is the duration of seismic excitation, and dt is the time integral;

[0058] S343, based on the stress anomaly analysis result and the vibration anomaly analysis result obtained by analysis, the installation quality of the GIS equipment is evaluated and analyzed, and the installation quality evaluation calculation formula is wherein K is the weight coefficient of the stress anomaly evaluation result Wf, and 0<K<1.

[0059] It needs to be explained that: in the anti-seismic performance simulation analysis link, first, the stress abnormality of GIS is evaluated and analyzed based on the equivalent stress of each key position, then the vibration abnormality of GIS is evaluated and analyzed based on the displacement of each key position, then the installation quality of GIS equipment is evaluated and analyzed based on the stress abnormality analysis result and the vibration abnormality analysis result obtained by analysis, and finally some technical solutions that do not meet the anti-seismic installation requirements are excluded based on the installation quality evaluation analysis result, not only can it be ensured that any scheme selected from the optimal solution set finally has at least a passing anti-seismic performance, avoiding the risk that the optimization result is mathematically optimal but physically unsafe, but also the optimization algorithm only analyzes and iterates the qualified schemes, which can greatly shorten the time to find the optimal solution set.

[0060] It needs to be noted that: when evaluating and analyzing the installation quality of GIS equipment, the system will first determine the equivalent stress of the key position and the displacement deviation of the key position, and when the equivalent stress of any group of key positions or the displacement deviation of any group of key positions is greater than the set maximum safety value, even if the final stress abnormality calculation result and the vibration abnormality calculation result are calculated to be qualified, this scheme is still excluded. Similarly, in the abnormality analysis process, when any one of the stress abnormality calculation result or the vibration abnormality calculation result exceeds the set maximum safety value, even if the final installation quality evaluation calculation result is within the qualified range, this scheme is still excluded.

[0061] Further, in one embodiment, the GIS key positions in S33 include the device support root, the pot-type insulator, the conductor connection, and the expansion joint.

[0062] In one embodiment, the mapping relationship model between the key arrangement parameters and the anti-seismic performance indicators is established by a response surface method or a neural network algorithm.

[0063] In one embodiment, the mapping relationship model between the key arrangement parameters and the anti-seismic performance indicators is established by a response surface method or a neural network algorithm.

[0064] It needs to be explained that: in the multi-objective optimization process, directly using finite element simulation for each evaluation calculation has high cost and long time consumption, through the mapping relationship model such as response surface or neural network, the anti-seismic performance can be predicted in real time and quickly, the optimization process is significantly accelerated, and the response surface method and the neural network algorithm can be verified and adjusted to ensure the model accuracy, consistent with the finite element simulation results. For example, the response surface method can capture the main trend through a second-order or third-order polynomial, and the neural network can handle nonlinearity through a hidden layer. The response surface method and the neural network algorithm are prior art, and will not be described in detail here.
