Description

Technical Field

[0001] The present invention relates to the field of energy storage power stations, and in particular to a battery array safety scenario analysis system. Background Art

[0002] Battery refers to a cup, trough or other container or part of a composite container that contains electrolyte solution and metal electrodes to generate electric current. It is a device that can convert chemical energy into electrical energy. It has positive and negative electrodes. With the advancement of science and technology, batteries generally refer to small devices that can generate electrical energy. Such as solar cells. The performance parameters of batteries mainly include electromotive force, capacity, specific energy and resistance. Using batteries as energy sources can obtain current with stable voltage, stable current, long-term stable power supply, and little external influence. In addition, the battery has a simple structure, is easy to carry, and is easy to charge and discharge. It is not affected by external climate and temperature. The performance is stable and reliable, and it plays a great role in all aspects of modern social life.

[0003] The typical working voltage of a battery at room temperature is also called the nominal voltage. It is a reference for selecting different types of batteries. The actual working voltage of a battery varies with different usage conditions and is equal to the difference between the equilibrium electrode potentials of the positive and negative electrodes. It is only related to the type of active material in the electrode, but not to the amount of active material. The battery voltage is essentially a DC voltage, but under certain special conditions, the phase change of metal crystals or certain phase-forming films caused by electrode reactions will cause slight fluctuations in voltage, a phenomenon called noise. The amplitude of the fluctuation is very small but the frequency range is very wide, so it can be distinguished from the self-excited noise in the circuit.

[0004] In the prior art, it is necessary to set up explosion-proof walls near the battery array of the energy storage power station to avoid safety accidents related to the battery array in the energy storage power station. However, whether there is an explosion-proof wall and whether the height of the explosion-proof wall is positively correlated with the number of batteries on site is a reference for judging whether the explosion-proof wall is set too high or too low, so as to avoid waste of materials and insufficient explosion-proof capacity. Obviously, the prior art lacks an intelligent analysis mechanism for judging whether there is an explosion-proof wall and whether the height of the explosion-proof wall is positively correlated with the number of batteries on site. Summary of the invention

[0005] In order to solve the technical problems in the prior art, the present invention provides a battery array safety scenario analysis system, which obtains the number of battery cells constituting the battery array of the energy storage power station and outputs it as the number of on-site batteries, determines the required height of the explosion-proof wall near the battery array based on the number of on-site batteries, and the distance from the explosion-proof wall near the battery array to the battery array is equal to the set distance. The determined required height of the explosion-proof wall near the battery array is positively correlated with the number of on-site batteries, and sends a thickness shortage signal when the physical thickness value corresponding to the explosion-proof wall is less than the required height of the explosion-proof wall near the battery array, thereby realizing intelligent identification of the reliability of the height of the explosion-proof wall near the battery array and improving the on-site safety level of the energy storage power station.

[0013] an intelligent identification device connected to the cubic interpolation device, and used to identify the imaging image blocks of the explosion-proof wall in the received cubic interpolation image, analyze the total number of pixel points passing through the imaging image blocks for each pixel row passing through the imaging image blocks, so as to obtain the total number of pixel points corresponding to each pixel row passing through the imaging image blocks, and determine the physical thickness value corresponding to the explosion-proof wall based on the maximum value of the total number of pixel points and the depth of field value corresponding to the cubic interpolation image, when the maximum value of the total number of pixel points remains unchanged, the determined physical thickness value corresponding to the explosion-proof wall is positively correlated with the depth of field value corresponding to the cubic interpolation image, and when the depth of field value corresponding to the cubic interpolation image remains unchanged, the determined physical thickness value corresponding to the explosion-proof wall is positively correlated with the maximum value of the total number of pixel points;

[0014] The parameter judgment device is connected to the intelligent identification device and the thickness conversion device respectively, and is used to send out a thickness deficiency signal when the physical thickness value corresponding to the explosion-proof wall is less than the required height of the explosion-proof wall near the battery array.
