Problems solved by technology

[0002] Distributed control of distribution network faults has the advantage of fast control speed. At the same time, distributed control also has certain potential safety hazards, because the computing power of the power distribution terminal STU is limited, and it cannot do complex encryption and authentication work. The equipment protection capabilities in the LAN weaker

Embodiment Construction

[0032] like Figure 1-8 As shown, the distribution network distributed intelligent control method based on the regional agent mode disclosed by the present invention includes the following steps:

[0033] Step 1, designate a terminal in the distribution network as the regional proxy server SRC, and the regional proxy server SRC regularly sends keys to each signal power monitoring unit STU in the system, and the keys include public keys and private keys;

[0034] Step 2. After the signal power monitoring unit STU detects a fault, it uses the current received private key to sign the fault detection information, and then sends the signed fault indication information to the regional proxy server SRC;

[0035] Step 3: After receiving the fault indication information and the switch displacement information reported by the outlet switch, the regional proxy server SRC uses the public key to verify the signed fault detection information, and performs fault location after the verificati...

Abstract

The invention provides a power distribution network distributed intelligent control method based on a regional agent mode. The method includes the steps of key management (KDC), STU fault detection, starting of fault positioning, isolation of faults, and fault recovery. The power distribution network distributed intelligent control method utilizes a regional agent mode to complete distributed FA, realizes management in a local area network, and realizes a complicated power supply recovery strategy.

Description

technical field [0001] The invention relates to a distributed intelligent control method for a distribution network, in particular to a distributed intelligent control method for a distribution network based on an area agent mode. Background technique [0002] Distributed control of distribution network faults has the advantage of fast control speed. At the same time, distributed control also has certain potential safety hazards, because the computing power of the power distribution terminal STU is limited, and it cannot do complex encryption and authentication work. The equipment protection capabilities in the LAN weaker. The present invention adopts the distributed FA under the agent control mode. In order to ensure the security of the whole system, a dual-network structure of communication between the WAN and the main station and communication between the LAN devices is adopted. Relatively simple digital signature measures are adopted between SRC and SRC to ensure the se...
