Description

TECHNICAL FIELD

[0001] The application relates to the electrical technology field, in particular to a deep integration circuit breaker with Beidou positioning and intelligent on-site protection capacitor power taking. BACKGROUND

[0002] The circuit breaker is a crucial protection device in the power system, and its main function is to quickly cut off the circuit when the current exceeds the set value, thereby protecting the safe operation of the power device and system.

[0003] On-site protection refers to the circuit breaker being able to quickly and independently perform protection actions when detecting fault current without relying on remote control signals. This protection method has the following advantages: 1. Fast response speed: on-site protection can detect faults and cut off the circuit within milliseconds, thereby minimizing the impact of faults on the power system. 2. High reliability: since on-site protection does not rely on remote signals, it is not affected by communication line faults or signal delays, and the protection action is more reliable. 3. Simplify system structure: using on-site protection can reduce dependence on remote control systems, simplifying the structure and maintenance of the power system.

[0004] In order to realize on-site protection, the circuit breaker needs to have an independent power supply, such as a battery as the main power supply for the circuit breaker on-site protection. However, if the battery fails or runs out of power, it will cause the protection action of the circuit breaker to be delayed or even unable to perform on-site protection, thereby causing safety hazards.

Those skilled in the art can know that, with the evolution of network architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0032] Exemplarily, Figure 1 A structural schematic diagram of a power system is shown, as Figure 1 The power system includes a circuit breaker, a grid line, and a storage capacitor cluster.

[0033] The circuit breaker can be a functionally composite circuit breaker. For example, the circuit breaker can be connected to the grid line to implement intelligent on-site protection for the grid line. Then, the circuit breaker can not only be powered by a traditional battery, but also can take power from the grid line to which the circuit breaker is connected, and then store the power obtained by taking power into the corresponding storage capacitor of the storage capacitor cluster. When the grid line is abnormal, the circuit breaker can not only obtain power from the battery to execute on-site protection, but also can obtain power from the corresponding storage capacitor of the storage capacitor cluster to execute on-site protection, to implement intelligent double backup of executing on-site protection, thereby improving the reliability of the circuit breaker in executing on-site protection. In addition, the circuit breaker is built-in with a processing chip, so that the circuit breaker can monitor the state of the grid line and analyze the state of the grid line through the processing chip.

[0034] The storage capacitor cluster can include a plurality of storage capacitors. One or more storage capacitors of the plurality of storage capacitors can be directly connected (or electrically connected / coupled) to the circuit breaker, and the plurality of storage capacitors can also have a connection (or electrical connection / coupling) relationship with each other, so that the circuit breaker can be directly or indirectly connected (or electrically connected / coupled) to each storage capacitor, to implement the ability to store power into each storage capacitor or obtain power from each storage capacitor. One or more storage capacitors in the storage capacitor cluster can also be directly or indirectly connected (or electrically connected / coupled) to other circuit breakers.

[0035] Exemplarily, Figure 2 The circuit breaker with Beidou positioning and intelligent on-site protection capacitor power taking deep integration provided by the embodiments of the present application can be configured to perform the following operations.

[0036] Step S1: The circuit breaker takes power from the grid line to which the circuit breaker is connected, and stores the power obtained by taking power into the corresponding storage capacitor.

[0037] For example, the circuit breaker can first determine whether it is currently a power taking opportunity by monitoring the state of the power grid line, i.e., only in a suitable power taking case, power is obtained from the power grid line, such as only in a suitable power taking case, the state of the power grid line is relatively stable, and the load is relatively low.

[0038] Specifically, the circuit breaker can periodically obtain the state of the power grid line. For ease of understanding, for the current period, the circuit breaker can obtain the voltage and current duration information of the power grid line at the preset time point of the current period, such as the starting time point of the current period. For example, the voltage and current duration information includes the voltage and current of multiple time points, and the number of multiple time points can be selected according to actual conditions, such as 20 or 30, etc. Thus, the processing chip of the circuit breaker analyzes the voltage and current duration information by the lightweight model built in the processing chip to determine whether the current period is a power taking opportunity. Among them, considering that the performance of the processing chip of the circuit breaker is relatively general, its lightweight model can be a model with relatively small computing power consumption, such as a fast neural network model. In this case, the circuit breaker needs to pre-process the voltage and current of multiple time points respectively, so that the voltage and current of multiple time points respectively have a structure when input to the fast neural network model, so that the fast neural network model can obtain accurate results even if the computing power is not strong.

[0039] For example, the circuit breaker interleaves the voltage and current of multiple time points according to the energy level to obtain the interleaved voltage and current. Among them, the interleaved voltage and current includes multiple groups of voltage and multiple groups of current, each group of voltage includes voltage sorted in order from high to low or from low to high according to the energy level, and each group of current includes current sorted in order from high to low or from low to high according to the energy level. If the voltage corresponding to the energy level in a group of voltage is missing in the voltage of multiple time points respectively, the voltage corresponding to the energy level is set to 0, and if the current corresponding to the energy level in a group of current is missing in the current of multiple time points respectively, the voltage corresponding to the energy level is set to 0, i.e., if the corresponding energy level in the interleaved group of current / voltage is missing in the voltage and current of multiple time points respectively, the value corresponding to the energy level in the group of current / voltage is set to 0.

[0040] For the convenience of understanding, an example is introduced. Taking the current at each time as an example, the time is 10 times, and the time sequence is 110, 107, 112, 108, 115, 116, 108, 110, 111, 108. The energy level is set to 3, from low to high, the first energy level is (105, 108], the second energy level is (108, 112], and the third energy level is (112, 116]. Then, after interleaving, each group is sorted from low to high in 3 capability levels, as follows: the first group: 0 (that is, there is no 110 at the beginning, which does not belong to the first energy level, so the voltage corresponding to the energy level is set to 0), 110 (that is, the first belongs to the second energy level), 115 (that is, the first belongs to the third energy level), the second group: 107 (that is, the first belongs to the first energy level), 112 (that is, the second belongs to the second energy level), 116 (that is, the second belongs to the third energy level), the third group: 108 (that is, the second belongs to the first energy level), 110 (that is, the third belongs to the second energy level), 0 (there is no third energy level, so the voltage corresponding to the energy level is set to 0), the fourth group: 108 (that is, the third belongs to the first energy level), 110 (that is, the fourth belongs to the second energy level), 0 (there is no third energy level, so the voltage corresponding to the energy level is set to 0), the fifth group: 108 (that is, the fourth belongs to the first energy level), 0 (there is no second energy level, so the voltage corresponding to the energy level is set to 0), 0 (there is no third energy level, so the voltage corresponding to the energy level is set to 0), and the final interleaved multiple currents are: 0, 110, 115, 107, 112, 116, 108, 110, 0, 108, 110, 0, 108, 0, 0. It can be seen that the final interleaved multiple currents are filled with multiple 0 elements, so that the value of the interleaved multiple currents is more volatile, and can better reflect the energy level. In this way, the processing chip of the circuit breaker can determine whether the current period is a power taking opportunity by analyzing the interleaved multiple voltages and currents through the lightweight model built in the processing chip, and the power taking opportunity is relatively more accurate.

[0041] Therefore, if the current is a power taking opportunity, the circuit breaker takes power from the power grid line and stores the power obtained by taking power into the corresponding storage capacitor. The corresponding storage capacitor can be the most suitable energy storage capacitor to improve the energy storage efficiency. For example, the circuit breaker takes power from the power grid line, and the circuit breaker can determine the storage capacitor that needs to be stored most from the storage capacitor cluster according to the energy storage state of the corresponding storage capacitor in the storage capacitor cluster, so that the circuit breaker stores the power obtained by taking power into the storage capacitor that needs to be stored most.

[0042] For example, the circuit breaker performs the following formula calculation:

[0043] ;

[0044] wherein, represents the energy storage state of the storage capacitor i connected with the circuit breaker in the storage capacitor cluster (may be the current power, the same below, not repeated here), is the weight corresponding to the storage capacitor i, represents the energy storage state of the j1th storage capacitor in the N1 storage capacitors connected with the storage capacitor i, is the weight corresponding to the j1th storage capacitor, and N1 is an integer greater than or equal to 0, represents the energy storage state of the j2th storage capacitor in the N2 storage capacitors connected with the j1th storage capacitor, is the weight corresponding to the j2th storage capacitor, and N2 is an integer greater than or equal to 0, and so on, represents the energy storage state of the jxth storage capacitor in the Nx storage capacitors connected with the jx-1th storage capacitor, is the weight corresponding to the jxth storage capacitor, and Nx is an integer greater than or equal to 0, , , ... until the value of is reduced in turn;

[0045] wherein, the storage capacitor most in need of energy storage is the storage capacitor with the smallest value of Ki in the storage capacitor cluster and connected with the circuit breaker. That is, the power of each storage capacitor and the power of all storage capacitors directly or indirectly connected (or electrically connected / coupled) to the storage capacitor are evaluated as a whole, so as to select the storage capacitor with the smallest overall power for energy storage, thereby improving the energy storage efficiency. Therefore, since the storage capacitors directly or indirectly connected (or electrically connected / coupled) to each storage capacitor are usually different, it is necessary to evaluate the overall power of each storage capacitor.

[0046] Step S2: In the case of monitoring the abnormality of the power grid line, the circuit breaker acquires energy from the corresponding storage capacitor, performs local protection, and the circuit breaker also reports abnormal information to the operation and maintenance center.

[0047] The abnormal information can indicate that the circuit breaker performs local protection, and the abnormal information can include the position information of the circuit breaker, which is obtained by Beidou positioning.

[0048] For example, before the circuit breaker acquires energy from the corresponding storage capacitor to perform local protection, the circuit breaker is configured to perform the following operations:

[0049] The circuit breaker can periodically determine the most suitable storage capacitor for power extraction within each cycle. Taking the current cycle as an example, within the current cycle (such as at any point in time within the current cycle), the circuit breaker can determine the most suitable storage capacitor for power extraction from the storage capacitor cluster based on the energy storage state of the corresponding storage capacitor. Therefore, the circuit breaker performs local protection by obtaining power from the corresponding storage capacitor, including: the circuit breaker performs local protection by obtaining power from the most suitable storage capacitor for power extraction.

[0050] For example, to determine the most suitable storage capacitor for current power draw, the circuit breaker can perform the calculation using the following formula:

[0051] ;

[0052] in, This represents the energy storage state of any storage capacitor i connected to the circuit breaker in the storage capacitor cluster during the current period. To store the weight corresponding to capacitor i, This represents the energy storage state of the t1-th storage capacitor among the M1 storage capacitors connected to storage capacitor i and also connected to other circuit breakers. Let M1 be the weight corresponding to the t1-th storage capacitor, where M1 is an integer greater than or equal to 0. This indicates the energy storage state of the t2th storage capacitor among the M2 storage capacitors that are connected to the t1th storage capacitor and also connected to other circuit breakers. Let M2 be the weight corresponding to the t2th storage capacitor, where M2 is an integer greater than or equal to 0, and so on. This represents the energy storage state of the tx-th storage capacitor among the Mx storage capacitors that are connected to the (tx-1)-th storage capacitor and are also connected to other circuit breakers. Let Mx be the weight corresponding to the (tx-1)th storage capacitor, where Mx is an integer greater than or equal to 0. , , ...until The values ​​decrease sequentially;

[0053] Among them, the most suitable storage capacitors for power extraction are: storage capacitor clusters connected to circuit breakers. The storage capacitor with the largest value is selected, similar to the above. In this case, the storage capacitor with the most abundant overall power can be chosen for power extraction. The impact of power extraction on other circuit breakers connected to this storage capacitor cluster is also minimized. In other words, this strategy not only requires selecting a storage capacitor capable of extraction but also minimizing the impact of power extraction on other circuit breakers.

[0054] In addition, the circuit breaker is configured to perform the following operations before detecting any abnormality in the power grid lines:

[0055] The circuit breaker acquires the voltage and the current persistence information of the power grid line at a preset time point in the current period;

[0056] The processing chip of the circuit breaker analyzes the voltage and the current persistence information by the lightweight model built-in the processing chip to determine the probability of the abnormality of the power grid line in the current period. For example, the voltage and the current persistence information can also include the respective voltage and current at multiple time points. The circuit breaker interleaves the respective voltage and current at multiple time points according to the energy level to obtain the interleaved multiple voltage and current, wherein the interleaved multiple voltage and current includes multiple groups of voltage and multiple groups of current, each group of voltage includes the voltage sorted in the order from high to low or from low to high according to the energy level, and each group of current includes the current sorted in the order from high to low or from low to high according to the energy level, if the voltage corresponding to the energy level is missing in the respective voltage at multiple time points in a group of voltage, the voltage corresponding to the energy level is set to 0, if the current corresponding to the energy level is missing in the respective current at multiple time points in a group of current, the voltage corresponding to the energy level is set to 0; the processing chip of the circuit breaker analyzes the interleaved multiple voltage and current by the lightweight model built-in the processing chip to determine the probability of the abnormality of the power grid line in the current period, and reports the probability to the operation and maintenance center. It should be understood that the principle of interleaving can refer to the related description above, which will not be described here.

[0057] In summary, since the circuit breaker takes power from the power grid line connected to the circuit breaker and stores the power energy obtained by taking power into the corresponding storage capacitor, even if the battery of the circuit breaker fails, is maintained or is insufficient, in the case of monitoring the abnormality of the power grid line, the circuit breaker can also acquire power energy from the corresponding storage capacitor to execute local protection, thereby improving the reliability of the circuit breaker executing local protection. In addition, since the circuit breaker also reports information indicating that the circuit breaker executes local protection and the position of the circuit breaker to the operation and maintenance center, the operation and maintenance center can timely know the position of the power grid line that fails and timely repair to reduce the loss caused by the failure.
