Problems solved by technology

[0003] (1) When generating a fault self-healing scheme, starting from the fault situation of the distribution network, heuristic search or optimization algorithm is used to obtain the optimal fault self-healing scheme. When formulating the self-healing scheme, there is a lack of comprehensive evaluation of the success of multiple remote operations. consideration;
[0004] (2) The distribution network fault self-healing scheme is out of touch with the actual control method, and the dispatcher needs to convert the self-healing scheme into an operation scheme, and then operate one by one, and the automation level is low;
[0005] (3) In the actual remote control operation, the remote control may fail. At this time, the self-healing scheme needs to be corrected, but the existing self-healing control method lacks consideration of this situation

Embodiment 1

[0034] 1. Generate initial self-healing scheme and remote control operation sequence;

[0035] 2. Perform the remote control operations in the operation sequence in order. Each time an operation is obtained, a remote control application is submitted to the dispatcher. After the dispatcher confirms the execution, the distribution automation system executes the operation and judges whether the returned execution result is successful; if the remote control execution is successful, continue to execute the next remote control operation of this remote control sequence ;Repeat until all remote control sequences have been executed

Embodiment 2

[0037] 1. Generate initial self-healing scheme and remote control operation sequence;

[0038] 2. Perform the remote control operations in the operation sequence in order. Each time an operation is obtained, a remote control application is submitted to the dispatcher. After the dispatcher confirms the execution, the distribution automation system executes the operation and judges whether the returned execution result is successful;

[0039] 3. If the remote control execution fails, notify the equipment maintenance personnel to go to the scene for emergency repair, and generate a backup self-healing plan and operation sequence at the same time;

[0040] 4. The emergency repair work takes a long time (more than 30 minutes), and the remote control operation is performed in accordance with the sequence of the backup self-healing plan to restore;

[0041] 5. After the repair work is over, the dispatcher will reconstruct the restored distribution network according to the initial se...

Abstract

The invention provides a smart distribution grid semi-closed loop self-healing control method aiming at the actual situation that an original self-healing scheme can not continue to be carried out probably because of remote control failure in the actual operation according to an operation sequence obtained through the self-healing scheme when a smart distribution grid carries out self-healing control. According to the technical scheme, when the smart distribution grid breaks down, the remote control operation sequence of the self-healing recovery scheme is obtained, and each step of remote control operation is carried out after being determined errorless by a dispatcher; once remote control failure happens, a standby self-healing scheme and a standby operation sequence are generated, and distribution grid self-healing is achieved according to the standby operation sequence; finally, it is ensured that the distribution grid operates in the optimum mode after seal-healing through distribution grid reconfiguration. According to the smart distribution grid semi-closed loop self-healing control method, the semi-automatic self-healing automatic control mode is achieved, the automation level of a self-healing control system is improved, self-healing scheme correction is carried out aiming at the remote control failure probably happening in seal-healing control, and the effectiveness and feasibility of distribution grid self-healing control are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering and relates to a practical application method of self-healing control suitable for an intelligent distribution network. Background technique [0002] Self-healing is a typical feature of smart distribution grids. The self-healing of the smart distribution network includes two meanings. When the system has a large operational risk, the distribution network needs to be able to actively identify potential safety hazards, reconfigure the distribution network, and reduce operational risks; The network can quickly identify faults, perform fault isolation and fault recovery, and minimize power loss due to faults. At present, in the practical application of the self-healing system of the smart distribution network, there are the following problems: [0003] (1) When generating a fault self-healing scheme, starting from the fault situation of the distribution network, heuristic search ...
