An electric power self-healing method for multi-node fault testing

Abstract

The invention relates to the technical field of electric power self-healing, in particular to a power self-healing method for multi-node fault testing. It includes the following steps: building multiple fault test nodes on the power grid; using a multi-node fault diagnosis algorithm to detect multiple fault test nodes, and extracting the status results of the power grid; using GPS positioning technology to locate faulty nodes and determining The position of the fault node of the power grid; the hybrid fault self-healing algorithm is used to perform self-healing control on the power grid; the power grid with successful self-healing control is issued a preventive self-healing control signal, and the power grid that fails to perform self-healing control is alarmed to remind the staff. The invention can accurately obtain the node position of the power grid fault, improve the recovery efficiency, and has a good self-healing effect. When the self-healing control fails to execute the power grid recovery, it will alarm and remind the staff in time, and check and repair according to the location of the faulty node to improve the use of the power grid. Safer and more practical.

Description

technical field [0001] The invention relates to the technical field of electric power self-healing, in particular to a power self-healing method for multi-node fault testing. Background technique [0002] With global warming, frequent natural disasters, serious environmental pollution, and insufficient traditional energy sources, ecological problems have become increasingly prominent. At the same time, to meet economic and social development, human needs for energy use, energy efficiency, and energy security have increased. The development and operation safety of the distribution network put forward higher requirements. As a system directly connected to the user, the failure of the distribution network will affect people's daily life and economic production. In this context, relying on modern information, communication and control Actively develop smart distribution network technology, which has become a common choice for the power industry to face future challenges, and the...

Problems solved by technology

[0003] In order to reduce the occurrence of large-scale cascading faults and power outages in the current smart distribution network, people have introduced the concept of self-healing into the power grid. When the self-healing control is executed, the self-healing control cannot be effectively performed on the faulty node, resulting in low efficiency of fault self-healing, which affects normal use, and cannot locate the faulty node where the recovery is unsuccessful, which is not conducive to the safety of the staff. Timely maintenance will further affect the use of the power grid, and the practicability is lacking. In view of this, we propose a power self-healing method for multi-node fault testing
