Power self-healing method for multi-node fault test

Abstract

The invention relates to the technical field of electric power self-healing and particularly relates to an electric power self-healing method for a multi-node fault test. The method comprises the following steps of constructing a plurality of fault test nodes on a power grid; detecting a plurality of fault test nodes by adopting a multi-node fault diagnosis algorithm, and extracting a power grid state result; positioning the fault node by adopting a GPS positioning technology, and determining the position of the fault node of the power grid; performing self-healing control execution on the power grid by adopting a hybrid fault self-healing algorithm; the power grid successfully executing self-healing control issuing a self-healing prevention control signal, and the power grid failed in self-healing control execution being alarmed to remind a worker. The method is advantaged in that the node position of the power grid fault can be accurately obtained, recovery efficiency is improved, the self-healing effect is good, when self-healing control execution power grid recovery fails, an alarm is given to remind a worker in time, troubleshooting and maintenance are carried out according to a fault node positioning position, use safety of the power grid is improved, and practicability is higher.

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
