Then, the target power distribution equipment 101 outputs the obtained electrical energy to the first load 12 in the star network formed by its own connection according to the preset power distribution rules, so as to ensure the normal operation of the first load 12 .

Second Embodiment

Referring to FIG. 2 , a second embodiment of the present invention provides a power distribution equipment fault adjustment method, and the power distribution equipment fault adjustment method is applied to any target power distribution equipment among a plurality of power distribution equipment in a power distribution system. The method for adjusting the fault of power distribution equipment includes: step S100, step S200 and step S300.

Step S100: when the target power distribution equipment generates a power distribution fault in the process of outputting the electrical energy obtained from the first power distribution equipment to the first load, determine the power distribution network topology according to the preset A target power distribution path that does not pass through the target power distribution device, wherein each power distribution device corresponds to a star network, and the power distribution network topology is composed of a plurality of star networks corresponding to a plurality of power distribution devices constitute.

In the power distribution system, a target power distribution device may be connected to at least one first power distribution device and at least one first load respectively, so as to form a star network centered on the target power distribution device. Wherein, the processing flow of the target power distribution device for each first power distribution device in the at least one first power distribution device is the same as that of other first power distribution devices in the at least one first power distribution device, and the target power distribution device The processing flow of the device for each of the at least one first load is the same as that of the other first loads in the at least one first load, so this embodiment uses any one of the at least one first power distribution device as the first load. A power distribution device, and taking any one of the at least one first loads as an example for detailed description.

In the case of normal power distribution, the target power distribution device is connected to the first power distribution device, so that the target power distribution device can obtain the electrical energy output from the first power distribution device and obtained from the power grid. The target power distribution device is connected to the first load, and the target power distribution device outputs the electric energy obtained from the first power distribution device to the first load, so as to realize power distribution for the first load.

In the case of abnormal power distribution, for example, when the target power distribution equipment is short-circuited or open-circuited and needs to be repaired by maintenance personnel, the target power distribution equipment cannot output the electrical energy obtained from the first power distribution equipment to the first load. At this time, the target power distribution equipment needs to adjust the power distribution to ensure that the first load can still maintain normal power distribution when the target power distribution equipment fails.

Specifically, a distribution network topology diagram of the power distribution system is preset in the target power distribution equipment. In the power distribution system, each power distribution device corresponds to a star network, so the distribution network topology can be composed of multiple star networks corresponding to multiple power distribution devices.

For example, in a power distribution system, power distribution equipment A forms a star network A by connecting load A1, load A2 and power distribution equipment B respectively, and power distribution equipment B forms a star network by connecting load B1 and power distribution equipment C respectively. Network B, while power distribution equipment C forms a star network C by connecting load C1, load A1 and power distribution equipment B respectively. And then the power distribution network topology diagram of the power distribution system composed of star network A, star network B and star network C, the distribution network topology diagram is: power distribution equipment B is connected to load B1, power distribution equipment respectively A is connected with power distribution equipment C, power distribution equipment A is connected with load A1 and load A2 respectively, and power distribution equipment C is also connected with load A1 and load C1 respectively.

Further, when the target power distribution equipment generates a power distribution fault in the process of outputting the electrical energy obtained from the first power distribution equipment to the first load, the target power distribution equipment can be based on the preset power distribution network topology map. , and determine a target distribution path that does not pass through the target distribution equipment. For example, if the target power distribution device A is connected to the first power distribution device B and the first load C, respectively, it is determined that a target power distribution path that does not pass through the target power distribution device can connect the first power distribution device B to the power distribution device D. The power distribution device D is then connected to the first load C.

It should be understood that there may be at least one path for re-outputting the electrical energy to the first load in the distribution network topology diagram, so the determined target distribution path should be the optimal choice in the at least one path.

Specifically, the method of determining the optimally selected target power distribution path may be that the target power distribution equipment determines all at least one power distribution path that does not pass through the target power distribution equipment from the power distribution network topology diagram, and the at least one distribution path does not pass through the target power distribution equipment. Each power distribution path in the electrical path is respectively connected to the first power distribution device and the first load, so as to ensure that the electrical energy output from the first power distribution device can be output to the first load from the direction of the path.

After the at least one power distribution path is determined, the target power distribution path obtains, according to the at least one power distribution path, the power surplus of each power distribution device in each power distribution path of the at least one power distribution path, and further obtains The power headroom of each power distribution path corresponds to the superposition of the power headroom of each power distribution device in each power distribution path. For example, in a power distribution path A of at least one power distribution path: the power surplus of the power distribution equipment A1 is 3KW, the power surplus of the power distribution equipment A2 is 4KW, and the power surplus of the power distribution equipment A3 is 3KW, Therefore, the power margin of distribution path A is 10KW.

Further, the target power distribution device may select a power distribution path to be determined with the least number of power distribution devices from at least one power distribution path. Wherein, in the process of selecting the to-be-determined power distribution path, the number of the to-be-determined power distribution path may have two optional situations.

As an implementation situation, when one power distribution path to be determined with the least number of power distribution devices is selected, that is, the number of power distribution devices in the power distribution path to be determined is the least among all paths. At this time, the target power distribution device can determine whether each power distribution device in the distribution path to be determined meets the preset conditions for transmitting electric energy, that is, determine the power surplus of each power distribution device in the distribution path to be determined. Whether all of them are greater than the power demand required to transmit electrical energy.

When it is judged to be yes, that is, the power surplus of each power distribution device in the to-be-determined distribution path is greater than the power demand required for the transmission of electrical energy, so it can satisfy the requirement that the electrical energy is transmitted to the first power distribution path on the to-be-determined distribution path. A load will not cause the power distribution equipment on the to-be-determined power distribution path to be overloaded. Further, it is determined that the to-be-determined power distribution path is the selected target power distribution path.

When the judgment is no, that is, the power surplus of at least one power distribution device in the to-be-determined distribution path is not greater than the power demand required for the transmission of electrical energy, so when the electrical energy is transmitted on the to-be-determined distribution path, it is not greater than At least one power distribution device that transmits the power demand required for electrical energy can be overloaded. Therefore, the to-be-determined distribution path cannot be used as the target distribution path. Afterwards, the target power distribution equipment selects a power distribution path with the least number of power distribution equipments from the at least one power distribution path except the power distribution path to be determined last time, and uses the power distribution path as the current judgment. The new to-be-determined distribution circuit returns to the step of "judging whether each power distribution device in the to-be-determined distribution path satisfies the preset conditions for transmitting the electric energy", until the to-be-determined distribution circuit is determined. Determine the distribution path as the target distribution path.

As another implementation situation, when at least two power distribution paths to be determined with the least number of power distribution devices are selected, that is, the number of power distribution devices in the at least two power distribution paths to be determined is the smallest among all paths. At this time, the target power distribution equipment needs to first determine the optimal selection from the at least two to-be-determined power distribution paths, that is, the target power distribution equipment first obtains the at least two to-be-determined power distribution paths for each of the to-be-determined power distribution paths. power headroom. Wherein, the power headroom of the power distribution path to be determined is also the sum of the power headroom of each power distribution device in the power distribution path to be determined. Then, the target power distribution device selects the power distribution path to be determined with the largest power headroom from the power headrooms of the at least two power distribution paths to be determined. It can be understood that the to-be-determined power distribution path with the largest power margin is the optimal choice among the at least two to-be-determined power distribution paths.

At this time, the target power distribution device can determine whether each power distribution device in the to-be-determined distribution path with the largest power headroom meets the preset conditions for transmitting electric energy, that is, the to-be-determined distribution path with the largest power headroom can also be determined. Whether the power surplus of each power distribution device in the system is greater than the power demand required for transmitting electrical energy.

When it is judged to be yes, that is, the power surplus of each power distribution device in the to-be-determined distribution path with the largest power headroom is greater than the power demand required for power transmission, so it can be satisfied that the power at the maximum power headroom The transmission to the first load on the to-be-determined distribution path will not cause the power distribution equipment on the to-be-determined distribution path with the largest power margin to be overloaded. Further, it is determined that the to-be-determined distribution path with the largest power margin is the selected target distribution path.

When the judgment is No, that is, the power distribution path to be determined with the largest power headroom has at least one power distribution equipment whose power reserve is not greater than the power demand required for transmitting electric energy. It is determined that at least one power distribution device that is not greater than the power demand required to transmit electrical energy is overloaded when transmitting on the distribution path. Therefore, the to-be-determined distribution path with the largest power headroom cannot be used as the target distribution path. Afterwards, the target power distribution equipment selects a distribution path with the smallest number of power distribution equipment from the at least one power distribution path except the power distribution path to be determined with the largest power margin determined last time, and assigns the power distribution path to the distribution path. As a new power distribution circuit to be determined for the current judgment, it returns to the step of "judging whether each power distribution device in the power distribution path to be determined meets the preset conditions for transmitting the electric energy", until A to-be-determined distribution path that satisfies the conditions is determined as the target distribution path.

Step S200: Generate corresponding power distribution adjustment information according to the target power distribution path.

After the target power distribution path is determined, the target power distribution device can generate power distribution adjustment information corresponding to the target power distribution path according to a preset control program. The power distribution adjustment information includes the ID of each power distribution device in the target power distribution path, and the power distribution handshake instruction of each power distribution device in the target power distribution path.

Of course, the generation of power distribution adjustment information including the above information in this embodiment is only an implementation of this embodiment, and is not intended to be a limitation of this embodiment.

S300: Transmit the power distribution adjustment information to the first power distribution device in the target power distribution path, so that the first power distribution device outputs the electrical energy to the first power distribution device through the target power distribution path a load.

After the target power distribution equipment generates power distribution adjustment information, the target power distribution equipment may first send the power distribution adjustment information to the first power distribution equipment connected to the target power distribution equipment in the target power distribution path. Therefore, according to the power distribution handshake command corresponding to itself in the power distribution adjustment information, the first power distribution device knows that the electric energy originally output to the target power distribution device needs to be re-processed through the connection relationship in the target power distribution path. output. Further, also according to the power distribution adjustment information, the first power distribution device sends the power distribution adjustment information to the power distribution devices connected in the target distribution path. Therefore, each power distribution device in the target distribution path forwards the power distribution adjustment information in turn, and each power distribution device in the target distribution path can correspond to its own power distribution handshake command from the power distribution adjustment information. Each power distribution device in the power distribution path outputs electric energy to the first load through the target power distribution path according to the power distribution handshake instruction.
