Problems solved by technology

However, this fault recovery mode that utilizes the network structure of the distribution network and the degree of automation of distribution equipment (sectioners, reclosers, etc.) is generally only applicable to distribution networks with relatively simple network connections, and cannot consider the actual load level and network operating constraints, and also does not have pre-simulation capabilities
When multi-power grid power supply appears in the power distribution network, this mode will not meet the actual requirements

Embodiment Construction

[0025] The system includes 4 parts: real-time subsystem, simulation subsystem, accident inversion subsystem and knowledge generation subsystem, and establishes network topology database, local historical database, rule database and example database, through the data interface from power distribution The automation system obtains real-time operation information of the power grid. The real-time subsystem monitors and processes the actual operation of the power grid, the simulation subsystem handles hypothetical accidents in the power grid, and the accident inversion subsystem plays back historical accidents. The network topology database stores the grid structure information, the rule base stores the rules on which reasoning is based, the example base stores historical cases, and the historical database stores the historical operation information of the distribution network.

Abstract

The invention belongs to the field of power network safety operation, and in particular relates to a distribution network failure isolation and quick power service restoration decision support system. The system is connected with a distribution automation system, comprises a real-time subsystem, a simulation subsystem, an accident inversion subsystem and a knowledge generating subsystem, and acquires power network operation monitoring data from the distribution automation system through a data interface, automatically tracks the real-time operating state of the power network, can quickly provide a power supply restoration scheme and intuitive simulation effect for a dispatcher to determine a proper restoration sequence after a failure happens, and provides accident simulation and accident inversion function; and the subsystems can be subjected to interface switching. The system is suitable for a distribution network which has a complicated network structure and of which the failure cannot be treated by automation equipment.

Description

technical field [0001] The invention belongs to the field of power grid safe operation, in particular to a distribution network fault isolation and fast power supply restoration decision support system. Background technique [0002] With the further improvement of the network structure and hardware facilities of the urban distribution network, the requirements for the reliability of power supply of the distribution network are getting higher and higher, and the indicators such as the annual average power outage time of users reflecting the reliability of power supply are related to the power distribution production department's response to power outages. Therefore, the power supply company usually uses the distribution automation system to improve the speed of fault detection and power restoration. The distribution automation system can not only obtain the remote signaling and telemetry information of the switch, but also can remotely control the action of the switch, and al...
