Description

Technical Field

[0001] The present invention relates to the technical field of electrochemical battery energy storage systems, and in particular to an energy storage system and a centralized noise reduction and control method for the energy storage system. Background Art

[0002] Nowadays, more and more electrochemical battery energy storage systems are deployed in more densely populated areas, which brings annoying noise problems to adjacent communities. The noise of energy storage system operation mainly comes from its cooling system, but other components (such as inverters and transformers) also generate relatively large noise, but the current market's main noise reduction measures for energy storage systems are also for their cooling systems.

[0003] There are usually two existing noise reduction methods. One is active noise reduction, in which an audio system is set up near the equipment or noise source. The audio system includes a microphone to receive sound and generate an anti-phase signal corresponding to the received sound. Based on the anti-phase signal, the sound source is eliminated to offset the noise of the liquid cooling system. Since an audio system needs to be set up on each independent container, and a large energy storage system generally contains dozens or hundreds of containers, the cost expenditure is increased. At the same time, the energy storage system is usually equipped with inverters and transformers, etc. These devices will generate certain noise, and the audio system set up on the container cannot process these noises. The second is passive noise reduction, in which a silent noise reduction box is installed at the sound source (i.e., the cooling system fan), and filled with sound-absorbing cotton and a resonance cavity to isolate the noise; and an air inlet hood is set on the top of the silent noise reduction box body, and a muffler is installed on the top of the silent noise reduction box body. However, due to the large size of the sound absorbing device, it not only increases the construction area of ​​the energy storage system, but is also extremely expensive.

[0004] Therefore, there is an urgent need for an energy storage system and a centralized noise reduction and control method for the energy storage system to solve the above problems. Summary of the invention

[0037] The following will be described in more detail with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the present invention.

[0038] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0039] like Figure 1 As shown, an embodiment of the present invention proposes an energy storage system, including: a centralized noise reduction control module, multiple energy modules, multiple noise reduction devices and an energy storage system control center module.

[0040] Specifically, the energy storage system control center module is connected to the energy module and the centralized noise reduction control module; the energy storage system control center module is used to control the charging and discharging operations of the energy module, and to send a control signal to the centralized noise reduction control module; the centralized noise reduction control module is connected to the noise reduction device, and the centralized noise reduction control module is used to simultaneously control a plurality of the noise reduction devices, and to regulate the operation of the noise reduction device in real time according to the control signal; a plurality of the energy modules are connected in parallel; a plurality of the noise reduction devices are arranged around the energy module, so as to reduce the noise signal generated when the energy module is in operation.

[0041] In this embodiment, the effect analysis of this embodiment can be explained from the following aspects: First, for the centralized noise reduction control module of the energy storage power station, by deploying noise reduction devices around the energy storage power station, it is possible to effectively capture a variety of noises of different frequencies and phases, and analyze them synchronously, and then generate corresponding anti-phase sound sources to offset the noise. This method can not only reduce the noise of the cooling system in the energy storage container, but also simultaneously reduce the noise of equipment such as inverters and transformers. Secondly, the centralized noise reduction control module is directly controlled by the energy storage system control center module and has no direct connection with a single energy storage container. Therefore, when any energy storage container fails and the cooling system is still operating normally, the noise reduction effect will not be disturbed. Finally, the centralized noise reduction control module is directly controlled by the energy storage system control center module. When the energy storage system control center module sends charging and discharging signals to the energy storage container, it will also send running signals to the centralized noise reduction control module to achieve real-time noise reduction. At the same time, during the charging and discharging process or in a static state, a standby signal will also be sent to the noise reduction device to reduce energy consumption.

[0042] In a specific example, the noise reduction device includes: a sound source capture module, a sound source phase and frequency separation and analysis module, a sound source signal storage, a similarity judgment module, an anti-phase sound source analysis and fitting module, a power enhancement module, and an anti-phase sound source release module.

[0043] Specifically, the sound source capture module, the sound source phase and frequency separation and analysis module, the sound source signal storage module and the similarity judgment module are connected in sequence; further, the sound source signal storage module is located between the sound source phase and frequency separation and analysis module and the similarity judgment module; the similarity judgment module is connected to the anti-phase sound source analysis and fitting module and the power enhancement module; the power enhancement module is connected to the anti-phase sound source release module.

[0044] In this embodiment, the sound source capture module is used to collect the noise signal generated by the energy module in real time, and transmit the noise signal to the sound source phase and frequency splitting and analyzing module; the sound source phase and frequency splitting and analyzing module splits and analyzes the noise signal in phase and frequency; the sound source signal memory is used to store the phase and frequency of the analyzed noise signal; the similarity judgment module is used to process the phase and frequency of the noise signal, and output the signal to the anti-phase sound source analysis fitting module, or output to the power enhancement module; the anti-phase sound source analysis fitting module is used to analyze and fit the noise signal whose similarity is less than a predetermined value, and generate the corresponding anti-phase sound source signal; the power enhancement module is used to enhance the power of the generated anti-phase sound source signal; the anti-phase sound source release module is used to release the enhanced anti-phase sound source signal at a set time and position. Among them, the predetermined value can be set according to actual conditions.

[0045] In a specific embodiment, the energy module includes a prefabricated energy storage battery compartment and an energy storage bidirectional inverter connected to each other.

[0046] In this embodiment, this embodiment can simultaneously reduce the noise of multiple energy storage battery prefabricated cabins and energy storage bidirectional inverters (AC-DC) through the settings of a sound source capture module, a sound source phase and frequency splitting and analyzing module, a sound source signal storage device, a similarity judgment module, an inverse sound source analysis and fitting module, a power enhancement module, and an inverse sound source release module, without the need to install noise reduction devices in each energy storage battery prefabricated cabin, thereby saving manpower, cost, time, and floor space. The centralized noise reduction control module of this embodiment realizes effective control of the noise of the energy storage system through intelligent and centralized processing methods, and improves the noise reduction efficiency and the overall performance of the system.

[0047] In addition, if Figure 2-Figure 3As shown, this embodiment also proposes a centralized noise reduction control method for an energy storage system, using the energy storage system as described above, specifically comprising the following steps:

[0048] S1, sending charging and discharging signals to the energy module through the energy storage system control center module, and sending control signals to the centralized noise reduction control module; and

[0049] S2. The centralized noise reduction control module controls the operation of the noise reduction device in real time according to the control signal, and simultaneously controls a plurality of the noise reduction devices to process the noise signals generated when the plurality of energy modules are in operation.

[0050] In one embodiment, the control signal includes: a noise reduction operation signal and a standby signal.

[0051] In step S2, the centralized noise reduction control module controls the operation of the noise reduction device in real time according to the control signal, specifically including: the centralized noise reduction control module cooperates with the charging and discharging operation of the energy module to control the operation of the noise reduction device in real time.

[0052] In step S2, the centralized noise reduction control module controls the operation of the noise reduction device in real time according to the control signal, and specifically includes: during charging and discharging or static time, the centralized noise reduction control module performs its own standby operation according to the standby signal from the energy storage system control center module.

[0053] In step S2, the simultaneous control of the plurality of noise reduction devices to process the noise signals generated when the plurality of energy modules are running specifically includes the following steps:

[0054] S201, collecting the noise signal emitted by the energy module through a sound source capture module;

[0055] S202, a sound source phase and frequency splitting and analyzing module splits and analyzes the noise signal;

[0056] S203: The similarity judgment module compares the phase and frequency of the noise signal obtained by analysis with the phase and frequency stored in the sound source signal memory and performs output processing.

[0057] In step S203, the similarity judgment module compares and outputs the phase and frequency of the noise signal obtained by analysis with the phase and frequency stored in the sound source signal memory, which specifically includes the following steps:

[0058] If the similarity between the phase and frequency of the noise signal and the phase and frequency stored in the sound source signal memory is greater than a predetermined value, the noise signal is deleted, and the corresponding signal is retrieved from the sound source signal memory and output to the power enhancement module for power enhancement, and the enhanced signal is output through the anti-phase sound source release module to offset the noise. In this embodiment, the retrieved signal is output to the power enhancement module for power enhancement processing to ensure that the intensity of the anti-phase sound source signal is sufficient to effectively offset the original noise signal. The enhanced signal is released at a set time and position by the anti-phase sound source release module, meets the original noise signal and achieves effective noise cancellation. In addition, this embodiment reduces the storage of duplicate data in the sound source signal memory by deleting new signals similar to the stored signals, thereby saving storage space; avoiding repeated analysis and processing of similar signals, and improving the overall processing efficiency of the system. By calling and enhancing the stored signals in real time, the noise changes are quickly responded to and the real-time noise reduction effect is achieved. Due to the reduction of repeated signal processing, the overall energy consumption of the system is reduced, and the energy utilization efficiency is improved.

[0059] If the similarity between the phase and frequency of the noise signal and the phase and frequency stored in the sound source signal memory is less than or equal to a predetermined value, the phase and frequency of the noise signal are stored, and the noise signal is output to the anti-phase sound source analysis and fitting module for analysis and fitting to generate an anti-phase sound source signal. Subsequently, the anti-phase sound source signal is enhanced by the power enhancement module and then released by the anti-phase sound source release module to offset the noise. By processing and storing all new noise signals that do not reach the similarity threshold, the system can more comprehensively cover and offset various noises generated in the energy storage system. The system can dynamically adapt to changes in noise in energy storage power stations, and even new or changing noise sources can be effectively handled.

[0060] In this embodiment, the energy storage system takes the energy storage power station as an example, and forms an energy module with one energy storage battery prefabricated cabin and one energy storage bidirectional inverter. After multiple energy modules are connected in parallel, they are uniformly controlled by the energy storage system control center module. Multiple noise reduction devices are arranged in the peripheral area of ​​the system, and the noise reduction devices do not interfere with each other and are uniformly controlled by the centralized noise reduction control module.

[0061] When noise reduction is required, for example, the noise emitted by the energy storage power station is collected through the sound source capture module on the noise reduction device; then, the sound source phase and frequency decomposition and analysis module decomposes the noise signal formed by the noise and calculates its phase and frequency; the phase and frequency of each noise are compared with the phase and frequency stored in the sound source signal memory.

[0062] If the phase frequency of the new noise (i.e., the noise emitted by the energy storage power station collected by the sound source capture module) is more than 90% similar to the phase frequency of the noise in the sound source signal memory, the new noise signal will be deleted without occupying the space of the sound source signal memory, and the original signal will be directly used and output to the power enhancement module, and output through the anti-phase sound source release module to cancel the noise. If the phase frequency of the new noise is less than 90% similar to the phase frequency of the noise in the sound source signal memory, the phase and frequency of the new noise are stored, and the signal is output to the anti-phase sound source analysis and fitting module, and then output by the power enhancement module and the anti-phase sound source release module to cancel the noise.

[0063] The noise reduction device of this embodiment has the function of comparing the newly captured noise signal with the stored noise signal, and makes a choice based on the signal similarity. At the same time, since the noise sources in the energy storage power station are mainly cooling systems, inverters and other equipment, and large-scale energy storage power stations are mostly built in suburbs and inaccessible areas, the noise sources are relatively single. After the preliminary noise analysis and storage, this embodiment does not need to consider more new noise. Therefore, this embodiment not only logically reduces the calculation amount of the system module, but also saves memory space and saves system response time.

[0064] Therefore, this embodiment can not only reduce the noise of the cooling system in the energy storage battery prefabricated cabin, but also reduce the noise of equipment such as inverters and transformers at the same time, with a wide range of noise reduction. In addition, this embodiment does not need to install a noise reduction system on each independent energy storage container, saving manpower, cost, time and space.

[0065] In summary, the energy storage system and the centralized noise reduction control method for the energy storage system proposed in the present invention have the following advantages:

[0066] Through the setting of a centralized noise reduction control module, multiple energy modules, multiple noise reduction devices and an energy storage system control center module; and the energy storage system control center module connects the energy module and the centralized noise reduction control module; the energy storage system control center module is used to control the charging and discharging operation of the energy module, and send a control signal to the centralized noise reduction control module; the centralized noise reduction control module is connected to the noise reduction device, and the centralized noise reduction control module is used to control multiple noise reduction devices at the same time, and regulate the operation of the noise reduction device in real time according to the control signal; multiple energy modules are connected in parallel; multiple noise reduction devices are arranged around the energy module to reduce the noise signal generated when the energy module is running. The present invention can reduce the noise of multiple energy modules at the same time, that is, reduce the noise of multiple energy storage battery prefabricated cabins and energy storage bidirectional inverters, without the need to be installed separately in each energy storage battery prefabricated cabin, reducing the number of noise reduction devices, and the noise reduction range is wide, which can save manpower, cost, time and space.

[0067] In addition, the centralized noise reduction control module of the present invention is directly controlled by the energy storage system control center module, which can achieve real-time noise reduction, and can adjust the operation or standby of the centralized noise reduction control module in real time according to the charging and discharging actions of the power station, and can also reduce energy consumption with a high degree of adjustment.

[0068] In addition, the noise reduction device of the present invention has the function of comparing the newly captured noise signal with the stored noise signal, and can select the signal according to the similarity, which can not only reduce the calculation amount of the system module, but also save the memory space and the system response time.

[0069] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
