Monitoring method for power distribution and utilization network topology

Abstract

The invention discloses a monitoring method for power distribution and utilization network topology. The monitoring method comprises the steps that a management system detects the voltage conditions of all nodes of the power distribution and utilization network topology; under the condition that the management system detects that the voltage of the power distribution and utilization network topology is outside the preset voltage interval, the management system detects whether the voltages on a first transmission line, a second transmission line and a third transmission line of the power distribution and utilization network topology are within the preset voltage interval or not; under the condition that the voltages on the first transmission line, the second transmission line and the thirdtransmission line are all within the preset voltage interval, the management system detects the voltage on a connection path connected with the first transmission line, the second transmission line and the third transmission line; and the management system quickly determines the area of the voltage, outside the preset voltage interval, on the power distribution and utilization network topology. Byadopting the monitoring method, the fault location of the power distribution and utilization network topology can be quickly detected.

Description

technical field [0001] The invention relates to the field of power distribution and utilization, in particular to a method for monitoring the topology of a power distribution and utilization network. Background technique [0002] Nowadays, the use of electricity permeates every aspect of people's lives. [0003] The reliability of the traditional power distribution network largely depends on the rationality of the distribution network topology and the operational reliability of related equipment. Although the reliability of power supply can be improved through a complex distribution network topology, the investment is huge, the construction is complicated, and the increase in equipment itself also reduces the overall robustness of the distribution network. On the other hand, there is inherently a single transmission path between the distribution network power source and the distribution network power supply at the end of power distribution, and the redundancy is insufficien...

Although the reliability of power supply can be improved through a complex distribution network topology, the investment is huge, the construction is complicated, and the increase in equipment itself also reduces the overall robustness of the distribution network.

On the other hand, there is inherently a single transmission path between the distribution network power source and the distribution network power supply at the end of power distribution, and the redundancy is insufficient. The reliability of power supply is largely limited by the reliability of the equipment itself. In the series connection mode, the reliability of power consumption of end users is further reduced, which is a problem that cannot be solved by the existing distribution network topology
