[0002] In recent years, with the vigorous promotion and development of clean energy, photovoltaic and wind power generation have achieved leapfrog development. Since the capacity of wind power and photovoltaic units in medium and low voltage distribution networks is small and the output is volatile, they are mostly connected to the distribution network in the form of distributed generation (DG). A large number of distributed power sources have transformed the distribution network from a traditional single-end radiation network to a multi-end multi-source network, and the network topology is more complex. Although the distribution automation master station can collect most of the node operation data in the network, with the expansion of the scale of the distribution network and the increase in the number of distributed power sources, the analysis and processing requirements of the master station increase, and the difficulty of optimization and solution becomes greater. The existing analysis and processing strategies gradually cannot meet the requirements of the distribution network for recovery speed. At the same time, when a communication failure occurs in the decision center, the reliability of centralized recovery is reduced.

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1: Figure 1This is a flowchart of a control analysis method based on blockchain provided in Embodiment 1 of the present invention. This embodiment can be applied to a control analysis system. This method can be executed by a control analysis system based on blockchain provided in an embodiment of the present invention. The system is composed of multiple software and hardware modules, such as Figure 1 As shown, the method specifically comprises the following steps:

[0042] S101, performing fault judgment and time removal management of the distribution network;

[0043] Exemplarily, in an embodiment of the present invention, each regional agent of the distribution network is controlled to detect the bus voltage and the current sampling information of each branch according to a set cycle to perform fault judgment detection; in this step, according to the set cycle, each regional agent is controlled to detect the bus voltage and the current sampling information of each branch. If there is information exceeding the set operating range, it is determined that a fault has occurred in the operation of the distribution network, and the information of each branch in the region and the protection information sent by the upstream and downstream adjacent regional agents are used to perform fault judgment. After determining the fault location, the fault area is isolated by controlling the circuit breaker action. At the same time, according to the severity of the fault, the area after the fault is divided into a light fault area and a heavy fault area. When the bus voltage U>0.2 and the voltage mutation angle ω<38°, the corresponding distribution network regional agent is determined to be in a light fault area. When the bus voltage U≤0.2 or the voltage mutation angle ω≥38°, it is considered that the regional agent is in a heavy fault area. Through this processing, the distribution network fault detection can be made more efficient and accurate, which is conducive to subsequent analysis and processing.

[0044] After receiving the information that there is a fault in the distribution network, the delayed removal processing of the downstream connecting branch is performed; in this step, when the regional agent is in a light fault state, the k values ​​of its upstream and downstream connecting branches are 1 and 0 respectively or the k value of the downstream connecting branch of the feeder agent is 0, and after the regional agent excludes the fault of the non-connecting branch in the area, if no information from the opposite side is received within the basic waiting time T, the step-by-step fault removal is started, starting from the regional agent at the end of the line and ending with the feeder agent of the substation, wherein on the basis of the basic waiting time T, for each additional agent, the removal time increases by a delay of △T, but the fault removal delay of each agent does not remain unchanged. When the feeder topology changes due to self-healing or economic reconstruction, the feeder agent is controlled to re-adjust the removal delay of each agent according to the latest network topology, and send it to the corresponding regional agent. Through this processing, the impact range caused by the distribution network fault can be effectively reduced to ensure the overall stable operation of the distribution network.

[0045] S102, performing power supply analysis and control on the power failure area of ​​the distribution network;

[0046] Exemplarily, in an embodiment of the present invention, after power is supplied to the power fault area of ​​the distribution network, power supply to the power fault area is adjusted and controlled according to the real-time data information of the feeder; when the feeder supplies power to the power fault area, due to the increase in load on the entire feeder, the current of multiple branches in the feeder will increase, and at the same time there is an increase in line voltage drop, resulting in a decrease in node voltage in the normal power area. In order to ensure that the current of each branch does not exceed the branch limit and the voltage is not lower than the minimum allowable voltage condition of the node, through this step, after power is supplied to the power fault area, the feeder current and the voltage of the normal power area are adjusted and controlled according to the power supply result information fed back in real time after power supply, so that they meet the above conditions, ensure the normal power supply transmission of the distribution network, and make the corresponding fault area agent become the normal area agent.

[0047] S103, performing fault self-healing control processing of the distribution network;

[0048] Exemplarily, in an embodiment of the present invention, after detecting and identifying the existence of fault information in the distribution network, the regional agent of the distribution network is analyzed and pre-processed; in this step, after detecting that a fault has occurred in the distribution network, the regional agent is controlled to disconnect the corresponding fault branch. If the fault occurs in the load branch, the power outage range is limited. If the fault occurs in the connecting branch, a large area of ​​power outage will appear downstream of the fault point, so self-healing control intervention is required to recover the distribution network. If the regional agent detects that the voltage and frequency are both out of limit and exceed the set time respectively, it can be determined that it is in the fault area and disconnect the circuit breakers of the upstream and downstream branches. After the corresponding unconnected area is formed in the fault area, the regional agent updates its own identity according to the type and operating status of the distributed power source to become a faulty regional agent or a controllable regional agent.

[0049] After receiving the information that the fault occurs in the connecting branch, a communication relationship is established with the feeder agent that is not directly above through the communication channel and forwarded by the normal regional agent. After obtaining power supply, the fault recovery of multiple scattered fault regional agents in the fault area is completed; in this step, the fault regional agent sends a power supply request to the regional agents adjacent to the downstream of the distribution network feeder through communication, wherein the power supply request includes the regional load priority of the fault regional agent and its own IP address information. After receiving the power supply request sent by the fault regional agent, the normal regional agent directly forwards the request to the upper-level feeder agent, so that it determines the fault location according to the normal regional agent, and sends the voltage corresponding to the normal regional agent, the total line impedance of the shortest electrical distance from the feeder outlet to the normal regional agent, and the feeder agent. The IP address is merged into the feeder constraint information, and the fault area agent that issued the request is directly replied according to the IP address in the power supply request, and the fault area agent is controlled to analyze the regional load balance. If the regional load balance is greater than 0, a transfer consent command is sent to the feeder agent according to the IP address, and the corresponding switch / circuit breaker is closed, otherwise a transfer refusal command is sent, wherein the feeder agent receives the transfer consent command sent by the fault area agent, sends a closing command to the corresponding normal area agent, completes the power supply to the specific fault area, and updates the fault area agent identity to the normal area agent. Through this processing, the fault recovery processing of the distribution network can be carried out to a certain extent, effectively avoiding the situation of immediate manual maintenance due to the occurrence of a fault, and reducing the consumption of manpower and material resources.

[0050] After completing the self-healing recovery process of the distribution network fault, the corresponding coordination processing is carried out; in this step, after completing the self-healing recovery process of the fault, when it is detected that the fault has not been repaired successfully, the result is transmitted to the corresponding workbench, waiting for manual processing, and at the same time maintaining the corresponding coordination processing of the fault area of ​​the coordinated distribution network.

[0051] S104, recording the certification of the fault repair of the distribution network;

[0052] Exemplarily, in an embodiment of the present invention, after the distribution network fault is self-healed and it is detected that the fault problem is solved, the result is provided to the corresponding staff for review and detection. When more than half of the staff members agree that the fault repair is successful, it is considered that the fault repair is completed, otherwise it is not completed;

[0053] The fault information and repair process of the distribution network are recorded and stored to provide a reliable basis for subsequent optimization processing.
