Description

Technical Field

[0001] The present application relates to the technical field of reactive power compensation, and in particular to a capacitor bank automatic switching method, system, intelligent terminal and storage medium. Background Art

[0002] In the power supply system, the power grid is responsible for distributing electric energy to each end user. With the rapid development of the economy and the transformation and upgrading of various industrial structures, users' dependence on electric energy has increased significantly, and the iteration and application of various power technology equipment have emerged in an endless stream.

[0003] During the power transmission operation of the power grid, various inductive devices and capacitive devices will consume a part of the power. Since this part of the power is not actually used by the electrical equipment, it does not actually do work through the electrical equipment. Therefore, this part of the power is also called reactive power. The part of the power that actually does work in the electrical equipment is called active power. The ratio of active power to reactive power is called power factor. The numerical value of the power factor can intuitively reflect the efficiency of the use of electric energy and the energy consumption of the current power grid.

[0004] Therefore, in order to improve the utilization efficiency of electric energy during the operation of the power grid, this can be achieved by improving the power factor. Connecting a capacitor bank in the line is one of the commonly used technical means to improve the power factor.

[0005] In the process of connecting capacitor groups, the capacitor groups in the equipment are usually put into use together. When the area where the equipment is located is in a period of low electricity consumption, the capacitor groups are not all at full load, that is, the number of capacitor groups put into use is higher than the actual demand for capacitor groups required for reactive power compensation, which increases the number of charge and discharge cycles of some capacitor groups, thereby accelerating the aging speed of the capacitor groups and increasing the operation and maintenance costs of electrical equipment. Summary of the invention

[0006] In order to put a reasonable number of capacitor banks into operation according to the real-time power supply, the present application provides a capacitor bank automatic switching method, system, intelligent terminal and storage medium.

[0007] In a first aspect, the present application provides a capacitor bank automatic switching method, which adopts the following technical solution:

[0008] The automatic switching method of capacitor bank includes:

[0009] Obtaining historical power supply information in a specified power distribution area, and dividing the power distribution area into multiple power intervals based on the historical power supply information;

[0010] Dividing a plurality of capacitor quantity distribution levels according to the number of capacitors, and establishing a mapping relationship between a plurality of the power intervals and a plurality of the capacitor quantity distribution levels;

[0011] Receive the actual power supply value of the power distribution area in real time;

[0012] Based on the actual power supply value and the multiple power intervals, identifying the target power interval in which the actual power supply value is located;

[0013] The capacitor quantity distribution level corresponding to the target power interval is matched, and a capacitor switching instruction is generated according to the capacitor quantity distribution level.

[0014] Through the above technical solution, before performing reactive power compensation in the designated distribution area, the historical power supply information in the designated distribution area is first obtained, especially the maximum power supply information, the minimum power supply information and the average power supply information, and a number of power intervals are divided according to the collected power supply information;

[0015] Then, a plurality of capacitor quantity distribution levels are divided according to the number of capacitors included in the device, and a mapping relationship between a plurality of power intervals and a plurality of capacitor quantity distribution levels is established, that is, the number of capacitors switched corresponding to a certain power interval is clarified;

[0016] Then, according to the actual power supply value received in real time and multiple power intervals, the power interval in which the actual power supply value is located, that is, the target power interval, is identified.

[0017] Finally, based on the target power range, the corresponding capacitor quantity distribution level is matched, and a capacitor switching instruction is generated according to the capacitor quantity distribution level, so that a corresponding number of capacitors can be switched according to the switching instruction.

[0018] In summary, this method can determine the number of capacitors required in real time based on the power supply power. Therefore, when the designated distribution area is in a low-power consumption period, some capacitors are put into use as needed, and the other capacitors are in a no-load state. This reduces the number of charge and discharge cycles of some capacitors, slows down the aging of the capacitors, and reduces the operation and maintenance costs of electrical equipment.

[0019] In a preferred example, the present application may be further configured as follows: after generating a capacitor switching instruction according to the capacitor quantity distribution level, the present application may further include:

[0020] Obtain the total switching times of multiple capacitors and the current arrangement sequence number of each capacitor;

[0021] If the total switching times is greater than or equal to a preset switching threshold, obtaining the individual switching times of each capacitor;

[0022] According to the individual switching times of each capacitor, and based on a plurality of individual switching times, an arrangement sequence number of a plurality of capacitors is updated;

[0023] Generate designated switching control instructions corresponding to a plurality of capacitors based on the updated arrangement sequence number;

[0024] If the total switching times is less than a preset switching threshold, a designated switching control instruction corresponding to a plurality of capacitors is generated according to the current arrangement sequence number.

[0025] Through the above technical solution, after the capacitor switching instruction is generated, by obtaining the total switching times of multiple capacitors and the current arrangement sequence number of each capacitor, when the total switching times is greater than or equal to the switching threshold (the switching threshold is a preset comparison trigger value), the switching times of each capacitor are obtained, and based on the individual switching times of the multiple capacitors, the arrangement sequence number of the capacitor is updated (such as sorting from small to large);

[0026] Then, based on the updated arrangement sequence number, the specified switching instructions corresponding to the multiple capacitors are generated to determine the capacitors to be switched. In this way, the capacitors with less usage can be switched on preferentially, thereby balancing the switching times of the various capacitors, thereby maintaining a balance in the switching times of the various capacitors. On the one hand, the charge storage capacity of the various capacitors is balanced to ensure smooth operation of the equipment. On the other hand, the aging speed of the various capacitors is made consistent, so that the operator can uniformly repair or replace the various capacitors, reducing the frequency of the operator's operation and maintenance of the equipment.

[0027] When the total switching times of the capacitors is less than a preset switching threshold, designated switching control instructions corresponding to the plurality of capacitors are generated according to the current capacitor arrangement sequence number.

[0028] In a preferred example, the present application may be further configured such that after the updated arrangement sequence number generates the designated switching control instructions corresponding to the plurality of capacitors, the method further includes:

[0029] If the total switching times of the plurality of capacitors is greater than a preset switching threshold, the total switching times is updated according to a preset initial value.

[0030] Through the above technical solution, if the total switching times of multiple capacitors is greater than the preset switching threshold, in addition to updating the arrangement serial numbers of the multiple capacitors, the total switching times will also be updated according to the preset initial value. The update here refers to updating the total switching times of each capacitor, such as zeroing update, so as to re-record the total switching times of each capacitor, so that it can be compared again through the preset switching threshold.

[0031] In a preferred example, the present application may be further configured as follows: in the updating of the arrangement sequence numbers of the plurality of capacitors based on the plurality of individual switching times, further comprising:

[0032] If there are two or more target capacitors with the same switching times, the target capacitors are sorted in ascending order based on the arrangement sequence numbers of the target capacitors before updating, and the arrangement sequence numbers of the target capacitors are updated.

[0033] With the continuous increase and balanced adjustment of the switching times of each capacitor, there is a possibility that two or more capacitors have the same switching times, and it is difficult to determine the updated capacitor arrangement sequence number based on the individual switching times of the capacitors. Through the above technical solution, based on the capacitor arrangement sequence number before the update, multiple target capacitors are sorted in order from small to large, so that the arrangement sequence numbers of multiple target capacitors can be completed, thereby avoiding the situation where two capacitors have the same switching times and maintaining stable operation of the equipment.

[0034] In a preferred example, the present application can be further configured as follows:

[0035] Monitor the voltage, current and current frequency of the capacitor in real time, and calculate the actual capacitance value of the corresponding target capacitor;

[0036] Compare the preset minimum capacitance threshold of the capacitor with the actual capacitance value;

[0037] If the minimum capacitance threshold is greater than or equal to the minimum capacitance threshold, capacitor aging alarm information carrying the target capacitor serial number is generated, and the capacitor aging alarm information is sent to the alarm device.

[0038] Through the above technical solution, by monitoring the operating information of the capacitor, such as voltage, current and current frequency values, the actual capacitance value of the capacitor is calculated, and the preset minimum capacitance threshold is compared with the actual capacitance value.

[0039] If the minimum capacitance threshold is greater than or equal to the actual capacitance value, a capacitor aging alarm message carrying the target capacitor serial number is generated and sent to the alarm device, which sounds an alarm so that the operator can identify the capacitor serial number with a lower actual capacitance value based on the alarm, so that the capacitor can be repaired or replaced.

[0040] In a preferred example, the present application can be further configured to calculate the actual capacitance value of the target capacitor using the following formula:

[0041]

[0042] in, is the actual capacitance value of the capacitor at present, is the current value of the capacitor, is the voltage value of the capacitor, is the capacitor current frequency.

[0043] The actual capacitance value of the target capacitor is calculated by the formula in the above technical solution, so as to compare the actual capacitance value with the minimum capacitance threshold.

[0044] In a second aspect, the present application provides a capacitor bank automatic switching system, which adopts the following technical solution:

[0045] A capacitor bank automatic switching system, comprising:

[0046] An information acquisition module, used to acquire historical power supply information in a specified power distribution area, and divide the power supply into multiple power intervals based on the historical power supply information;

[0047] A mapping relationship establishing module, used for dividing a plurality of capacitor quantity distribution levels according to the quantity of capacitors, and establishing a mapping relationship between a plurality of the power intervals and a plurality of the capacitor quantity distribution levels;

[0048] An information acquisition module is used to receive the actual power supply value of the power distribution area in real time;

[0049] an interval identification module, which identifies a target power interval in which the actual power supply value is located based on the actual power supply value and the multiple power intervals;

[0050] The switching instruction generating module is used to match the corresponding capacitor quantity distribution level according to the target power interval, and generate a capacitor switching instruction according to the capacitor quantity distribution level.

[0051] Through the above technical solution, each of the above functional modules in the system switches a reasonable number of capacitors through its own functions and the collaboration between modules.

[0052] In a third aspect, the present application provides an intelligent terminal, which adopts the following technical solution:

[0053] A smart terminal, comprising a processor and a memory, wherein the memory stores at least one instruction, at least one program, a code set or an instruction set, and the at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by the processor to implement the processing of the smart terminal in the above-mentioned capacitor bank automatic switching method.

[0054] In a fourth aspect, the present application provides a computer-readable storage medium, which adopts the following technical solution:

[0055] A computer-readable storage medium stores at least one instruction, at least one program, a code set or an instruction set, wherein the at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by a processor to implement the processing of an intelligent terminal in the above-mentioned capacitor bank automatic switching method.

[0056] In summary, this application includes the following beneficial technical effects:

[0057] 1. By establishing a mapping relationship between the power interval and the capacitor quantity distribution level, and identifying the power interval according to the actual power supply value, the target power interval can be obtained. Based on the obtained target power interval, a capacitor switching instruction is generated, and the number of capacitors required to be switched can be determined.

[0058] Therefore, when the designated distribution area is in the off-peak period, some capacitors are put into use as needed, while the other capacitors that are not switched on are in a no-load state, which reduces the number of charge and discharge cycles of some capacitors, slows down the aging of capacitors, and reduces the operation and maintenance costs of electrical equipment;

[0059] 2. When the total switching times of multiple capacitors is greater than the switching threshold, the arrangement serial number of the capacitors is updated according to the individual switching times of the multiple capacitors, and the capacitors to be switched are determined according to the updated arrangement serial number of the capacitors, so that the capacitors with fewer uses can be switched first, thereby balancing the switching times of each capacitor, thereby maintaining a balance in the switching times of each capacitor. This can not only maintain a balance in the charge storage capacity between the capacitors, allowing the equipment to run smoothly, but also make the aging speed of each capacitor tend to be consistent, so that the operator can uniformly repair or replace each capacitor, reducing the frequency of the operator's operation and maintenance of the equipment.

[0066] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0067] An embodiment of the present application discloses an automatic switching method for a capacitor bank. The method can be applied to a device for performing reactive power compensation on a power supply system. The capacitor in the reactive power compensation device is one of the core components of reactive power compensation. Switching capacitors is one of the commonly used technical means for performing reactive power compensation.

[0068] The following will combine the specific implementation methods and specific usage scenarios to describe the attached Figure 1 The processing flow shown in is described here, and other similar usage scenarios will not be described in detail later.

[0069] Step 101: Obtain historical power supply information in a specified power distribution area, and divide the historical power supply information into multiple power intervals.

[0070] During implementation, before performing reactive power compensation in a designated distribution area, the operator obtains historical power supply information in the designated distribution area, including the highest power supply information, the lowest power supply information, and the average power supply information, etc., and divides the power value span of the power supply into several power intervals reasonably based on the power supply information collected above, so as to facilitate the subsequent determination of the number of capacitor switching and provide a basis for judgment.

[0071] Step 102: divide a plurality of capacitor quantity distribution levels according to the quantity of capacitors, and establish a mapping relationship between a plurality of power intervals and a plurality of capacitor quantity distribution levels.

[0072] In implementation, each capacitor quantity distribution level corresponds to a different number of capacitors to be switched. By establishing a mapping relationship between multiple power intervals and multiple capacitor quantity distribution levels, the capacitor quantity distribution level corresponding to a certain power interval can be clearly identified, thereby determining the number of capacitors to be switched.

[0073] Step 103: Receive the actual power supply value of the power distribution area in real time.

[0074] In implementation, the actual power supply power of the designated power distribution area is received to provide a basis for the subsequent power range determination.

[0075] Step 104: Based on the actual power supply value and the multiple power intervals, identify the target power interval in which the actual power supply value is located.

[0076] In implementation, the power interval in which the actual power supply power is located, that is, the target power interval, is identified according to the actual power supply power and the endpoint values ​​of the power interval.

[0077] Step 105 , matching the corresponding capacitor quantity distribution level according to the target power range, and generating a capacitor switching instruction according to the capacitor quantity distribution level.

[0078] In implementation, based on the target power range, the corresponding capacitor quantity distribution level is matched, and a capacitor switching instruction is generated according to the capacitor quantity distribution level, so that a corresponding number of capacitors can be switched according to the switching instruction.

[0079] The automatic switching method of capacitors described in this embodiment can determine the number of capacitors required in real time according to the power supply power. Therefore, when the designated power distribution area is in a low power consumption period, some capacitors are put into use as needed, and other capacitors are in a no-load state, thereby reducing the number of charge and discharge cycles of some capacitors, thereby slowing down the aging speed of the capacitors and reducing the operation and maintenance costs of electrical equipment.

[0080] Optionally, after step 105, that is, after generating the capacitor switching instruction according to the capacitor quantity distribution level, the following processing may be performed:

[0081] Step 201: Obtain the total switching times of multiple capacitors and the current arrangement sequence number of each capacitor.

[0082] In implementation, after the capacitor switching instruction is generated, the total switching times of the plurality of capacitors is obtained, that is, the sum of the individual switching times of each capacitor, and the current arrangement sequence number of each capacitor is obtained.

[0083] Step 202: If the total switching times is greater than or equal to a preset switching threshold, the individual switching times of each capacitor are obtained.

[0084] In implementation, a switching threshold is set for the capacitor, that is, a preset comparison trigger value, and when the total switching times of multiple capacitors is greater than or equal to the preset switching threshold, the individual switching times of each capacitor are obtained.

[0085] Step 203: updating arrangement sequence numbers of the plurality of capacitors according to the individual switching times of each capacitor and based on the plurality of individual switching times.

[0086] In implementation, based on the number of individual switching times of multiple capacitors, the arrangement serial numbers of the capacitors are updated in a certain order (such as from small to large), that is, according to the number of individual switching times of the capacitors, they are reordered from small to large, so as to filter out capacitors with fewer switching times.

[0087] Step 204: Generate designated switching control instructions corresponding to a plurality of capacitors based on the updated arrangement sequence number.

[0088] During implementation, after a new capacitor arrangement serial number is generated, designated switching control instructions for multiple capacitors are generated according to the updated capacitor arrangement serial number, from small to large according to the corresponding capacitor quantity distribution level. This can balance the switching times of each capacitor by giving priority to switching capacitors with fewer individual switching times, thereby maintaining a balance in the switching times of each capacitor.

[0089] The above capacitor screening process, on the one hand, maintains the balance of charge storage capacity between the capacitors so that the equipment can run smoothly; on the other hand, it makes the aging speed of the capacitors tend to be consistent, so that the operator can uniformly repair or replace the capacitors, reducing the frequency of the operator's operation and maintenance of the equipment.

[0090] Step 205: if the total switching times are less than the preset switching threshold, then generating designated switching control instructions corresponding to a plurality of capacitors according to the current arrangement sequence number.

[0091] In implementation, when the total switching times of the plurality of capacitors is less than a preset switching threshold, there is no need to update the capacitor arrangement sequence number, and the designated switching control instructions corresponding to the plurality of capacitors are generated according to the current capacitor arrangement sequence number.

[0092] Optionally, after step 204, that is, after generating the designated switching control instructions corresponding to the plurality of capacitors based on the updated arrangement sequence number, the following processing may also be performed:

[0093] If the total switching times of the plurality of capacitors is greater than a preset switching threshold, the total switching times is updated according to a preset initial value.

[0094] In implementation, if the total switching times of multiple capacitors is greater than a preset switching threshold, in addition to updating the arrangement serial numbers of the multiple capacitors, the total switching times will also be updated according to a preset initial value. The update here refers to updating the total switching times of each capacitor, such as zeroing update, so as to re-record the total switching times of each capacitor, so that it can be compared again through the preset switching threshold.

[0095] Optionally, in the process of step 203, that is, in the process of updating the arrangement sequence numbers of the plurality of capacitors based on the plurality of individual switching times, the following may be performed:

[0096] If there are two or more target capacitors with the same switching times, the target capacitors are sorted in ascending order based on the arrangement sequence numbers of the target capacitors before updating, and the arrangement sequence numbers of the target capacitors are updated.

[0097] In practice, as the switching times of each capacitor in the reactive compensation device increase, there is a possibility that two or more capacitors may have the same switching times. In this case, it is difficult to determine the updated capacitor arrangement serial number based on the individual switching times of the capacitors.

[0098] At this time, based on the capacitor arrangement serial number before the update, multiple target capacitors can be sorted in ascending order, so that the arrangement serial numbers of multiple target capacitors can be completed, thereby avoiding the situation where two capacitors have the same switching times, so as to maintain stable operation of the equipment.

[0099] Optionally, the capacitor automatic switching method of the embodiment of the present application further includes the following processing:

[0100] Step 301: monitor the voltage, current and current frequency of the capacitor in real time, and calculate the actual capacitance value of the corresponding target capacitor;

[0101] In implementation, the actual capacitance value of the capacitor is calculated by monitoring various operating information of the capacitor, such as voltage, current and current frequency values.

[0102] Step 302: Compare the preset minimum capacitance threshold of the capacitor with the actual capacitance value;

[0103] In implementation, the lowest capacitance threshold of the capacitor is compared with the actual capacitance value so as to determine the current aging condition of the capacitor.

[0104] Step 303: If the minimum capacitance threshold is greater than or equal to the minimum capacitance threshold, capacitor aging alarm information carrying the target capacitor serial number is generated, and the capacitor aging alarm information is sent to the alarm device.

[0105] During implementation, the alarm device issues an alarm based on the capacitor aging alarm information, so that the operator can identify the capacitor serial number with a lower actual capacitance value based on the alarm, so that the capacitor can be repaired or replaced, thereby ensuring the normal operation of the reactive compensation equipment.

[0106] Optionally, the formula for calculating the actual capacitance value of the generated target capacitor is as follows:

[0107]

[0108] in, is the actual capacitance value of the capacitor at present, is the current value of the capacitor, is the voltage value of the capacitor, is the capacitor current frequency.

[0109] According to the above formula, combined with the monitored capacitor operation data, the actual current capacitance value of the capacitor is calculated. , so as to compare the actual capacitance value with the minimum capacitance threshold.

[0110] Based on the above invention concept, the present application also provides a capacitor automatic switching system, such as Figure 4 As shown, the capacitor automatic switching system includes:

[0111] The information acquisition module 401 is used to acquire historical power supply information in a specified power distribution area, and divide the power distribution area into multiple power intervals based on the historical power supply information.

[0112] The mapping relationship establishing module 402 is used to divide the number of capacitors into a plurality of capacitor quantity distribution levels according to the number of capacitors, and establish a mapping relationship between a plurality of the power intervals and a plurality of the capacitor quantity distribution levels.

[0113] The information acquisition module 401 is used to receive the actual power supply value of the power distribution area in real time.

[0114] The interval identification module 403 identifies a target power interval in which the actual power supply value is located based on the actual power supply value and the multiple power intervals.

The memories and storage media may be short-term storage or permanent storage.
