Then, the target power distribution device 101 outputs the obtained power to the first load 12 in the star network formed by connecting itself according to the preset power distribution rule, 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, which is applied to any target power distribution equipment in a plurality of power distribution equipment of an electric power distribution system. The fault adjustment method for the power distribution equipment comprises the following steps: 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 electric energy obtained from the first power distribution equipment to the first load, a target power distribution path which does not pass through the target power distribution equipment is determined according to a preset power distribution network topological graph, wherein each power distribution equipment corresponds to a star network, and the power distribution network topological graph is formed by a plurality of star networks corresponding to a plurality of power distribution equipment.
In the power distribution system, the 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 constitute a star network centered on the target power distribution device. The processing flow of the target power distribution device for each of the at least one first power distribution device is the same as that of the other first power distribution devices in the at least one first power distribution device, and the processing flow of the target power distribution 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 that the present embodiment takes any one of the at least one first power distribution device and any one of the at least one first load as an example for detailed description.
Under the condition of normal power distribution, the target power distribution equipment is connected with the first power distribution equipment, and the target power distribution equipment can obtain the electric energy output by the first power distribution equipment and obtained from a power grid. The target power distribution equipment is connected with the first load, and the target power distribution equipment outputs the electric energy obtained from the first power distribution equipment to the first load so as to realize power distribution for the first load.
When power distribution is abnormal, for example, when a fault such as a short circuit or an open circuit occurs in the target power distribution equipment and needs to be repaired by a service person, the target power distribution equipment cannot output the electric energy obtained from the first power distribution equipment to the first load. At this time, the target distribution equipment needs to adjust the distribution to ensure that the first load can also maintain normal distribution when the target distribution equipment fails.
Specifically, a power distribution network topological graph of the power distribution system is preset in the target power distribution equipment. In the power distribution system, each distribution device corresponds to a star network, so the distribution network topology can be formed by a plurality of star networks corresponding to a plurality of distribution devices.
For example, in an electrical power distribution system, distribution equipment a forms a star network a by connecting load a1, load a2, and distribution equipment B, respectively, distribution equipment B forms a star network B by connecting load B1, and distribution equipment C, respectively, and distribution equipment C forms a star network C by connecting load C1, load a1, and distribution equipment B, respectively. And then star network A, star network B and star network C form the distribution network topological diagram of this electric power distribution system, this distribution network topological diagram is: distribution B is connected to load B1, distribution a, and distribution C, distribution a is connected to load a1 and load a2, respectively, and distribution C is connected to load a1 and load C1, respectively.
Further, when the target power distribution equipment generates a power distribution fault in the process of outputting the electric energy obtained from the first power distribution equipment to the first load, the target power distribution equipment can determine a target power distribution path which does not pass through the target power distribution equipment according to a preset power distribution network topological graph. For example, the target distribution device a is connected to the first distribution device B and the first load C, and then it is determined that a target distribution path that does not pass through the target distribution device may be connected to the distribution device D for the first distribution device B, and the distribution device D is connected to the first load C.
It should be appreciated that the path for re-outputting the electrical energy to the first load may be at least one path in the distribution network topology, and thus the determined target distribution path should be an optimal choice of the at least one path.
Specifically, the method for determining the optimally selected target power distribution path may be that the target power distribution device determines, from the power distribution network topology map, all at least one power distribution path that does not pass through the target power distribution device, and each power distribution path in the at least one power distribution path is connected to the first power distribution device and the first load, so as to ensure that the power output from the first power distribution device can be output to the first load in the direction of the path.
After at least one power distribution path is determined, the target power distribution path obtains the power surplus of each power distribution device in each power distribution path of the at least one power distribution path according to the at least one power distribution path, and further obtains the power surplus of each power distribution path corresponding to the sum of the power surplus of each power distribution device in each power distribution path. For example, in a power distribution path a of the at least one power distribution path: the remaining power of the distribution device a1 was 3KW, the remaining power of the distribution device a2 was 4KW, and the remaining power of the distribution device A3 was 3KW, so the remaining power of the distribution route a was 10 KW.
Further, the target power distribution equipment can select a power distribution path with the least number of power distribution equipment to be determined from the at least one power distribution path. In the process of selecting the power distribution path to be determined, the number of the power distribution paths to be determined can have two selectable situations.
As an implementation case, when the power distribution path to be determined with the least number of power distribution devices is selected as 1, that is, the number of power distribution devices in the power distribution path to be determined is the smallest among all paths. At this time, the target power distribution device may determine whether each power distribution device in the power distribution path to be determined satisfies a preset condition for transmitting the electric energy, that is, determine whether the power remaining amount of each power distribution device in the power distribution path to be determined is greater than the power demand amount required for transmitting the electric energy.
If the power residual quantity of each power distribution device in the power distribution path to be determined is greater than the power demand quantity required for transmitting the electric energy, the condition that the power distribution devices on the power distribution path to be determined are overloaded when the electric energy is transmitted to the first load on the power distribution path to be determined can be met. And determining the power distribution path to be determined as the selected target power distribution path.
If the power distribution path to be determined is not the power distribution path to be determined, namely the power surplus of at least one power distribution device in the power distribution path to be determined is not larger than the power demand required for transmitting the electric energy, when the electric energy is transmitted on the power distribution path to be determined, at least one power distribution device which is not larger than the power demand required for transmitting the electric energy can run in an overload mode. Therefore, the power distribution path to be determined cannot be the target power distribution path. Then, the target power distribution equipment selects a power distribution path with the least number of power distribution equipment except the last determined power distribution path to be determined from at least one power distribution path, and the power distribution path is used as a new power distribution circuit to be determined for current judgment, and the following steps are returned to be executed: and judging whether each power distribution device in the power distribution path to be determined meets the preset condition for transmitting the electric energy or not until the power distribution path to be determined meeting the preset condition is determined to be used as a target power distribution path.
As another implementation case, when at least two power distribution paths to be determined are selected, where the number of power distribution devices is the minimum, that is, the number of power distribution devices in the at least two power distribution paths to be determined is the minimum among all the paths. At this time, the target power distribution device needs to determine an optimal selection from the at least two to-be-determined power distribution paths, that is, the target power distribution device first obtains the power headroom of each to-be-determined power distribution path of the at least two to-be-determined power distribution paths. And the power surplus of the power distribution path to be determined is also the sum of the power surplus of each power distribution device in the power distribution path to be determined. And then, the target power distribution equipment selects the power distribution path to be determined with the maximum power margin from the power margins of the at least two power distribution paths to be determined. It can be understood that the power distribution path to be determined with the largest power margin is the optimal selection of the at least two power distribution paths to be determined.
At this time, the target power distribution device may determine whether each power distribution device in the power distribution path to be determined having the largest power headroom satisfies a preset condition for transmitting the electric energy, that is, determine whether the power surplus of each power distribution device in the power distribution path to be determined having the largest power headroom is greater than a power demand required for transmitting the electric energy.
If the power residual amount of each power distribution device in the power distribution path to be determined is larger than the power demand required for transmitting the electric energy, the condition that the electric energy is transmitted to the first load on the power distribution path to be determined with the maximum power residual amount cannot cause overload of the power distribution device on the power distribution path to be determined with the maximum power residual amount is met. And determining the power distribution path to be determined with the maximum power margin as the selected target power distribution path.
If the power surplus is not greater than the power demand required for transmitting the electric energy, the at least one power distribution device which is not greater than the power demand required for transmitting the electric energy is overloaded when the electric energy is transmitted on the power distribution path to be determined with the maximum power surplus. Therefore, the power distribution path to be determined, for which the power margin is the largest, cannot be the target power distribution path. Then, the target power distribution equipment selects a power distribution path with the least number of power distribution equipment except the power distribution path to be determined which is determined last time and has the largest power margin from at least one power distribution path, and the power distribution path is used as a new power distribution circuit to be determined for current judgment, and the execution is returned: and judging whether each power distribution device in the power distribution path to be determined meets the preset condition for transmitting the electric energy or not until the power distribution path to be determined meeting the preset condition is determined to be used as a target power distribution path.
Step S200: and generating corresponding power distribution regulation information according to the target power distribution path.
After the target power distribution path is determined, the target power distribution equipment can generate power distribution regulation information corresponding to the target power distribution path according to a preset control program. The power distribution regulation information comprises 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 the power distribution adjustment information including the above information in the present embodiment is only one implementation manner of the present embodiment, and is not limited to the present embodiment.
S300: transmitting the power distribution regulation information to the first power distribution device in the target power distribution path to cause the first power distribution device to output the electrical energy to the first load through the target power distribution path.
After the target power distribution device generates the power distribution regulation information, the target power distribution device may first transmit the power distribution regulation information to a first power distribution device connected to the target power distribution device in the target power distribution path. Therefore, the first power distribution equipment acquires that the electric energy which is originally output to the target power distribution equipment needs to be output again through the connection relation in the target power distribution path according to the power distribution handshake instruction corresponding to the first power distribution equipment in the power distribution regulation information. Further, the first power distribution device transmits the power distribution regulation information to the power distribution devices connected in the target power distribution path also according to the power distribution regulation information. The event all forwards this distribution adjustment information in proper order through every distribution equipment in the target distribution route, and every distribution equipment all can follow distribution adjustment information and correspond the distribution instruction of shaking hands of self in this target distribution route, and every distribution equipment all shakes hands the instruction according to this distribution in the target distribution route to make and export the electric energy to first load through the target distribution route.
