Embodiment

[0023] A method for optimizing the implementation plan for the overhaul of the distribution network, the specific steps are as follows:

[0024] (1) Read in the information of the power distribution network and various power distribution equipment, including the load fluctuation and topology of the power grid, the status of the power distribution equipment, maintenance level, failure rate parameters, last maintenance time, maintenance cost, and fault replacement Expenses, troubleshooting expenses, etc.;

[0025] (2) The equipment to be overhauled is grouped according to the constraints of simultaneous overhaul, and the equipment overhauled at the same time is grouped together to generate an initial overhaul plan;

[0026] (3) Calculate the failure probability of power distribution equipment under different states and different maintenance levels during each maintenance period. When different power distribution equipment is in different health states, the probability of failure is di...

Abstract

The invention discloses an optimization method of an embodiment for overhauling a power distribution network. The method comprises the following steps: collecting information of the power distribution network and power distribution equipment; calculating the failure rate of the power distribution equipment; evaluating operational risks of the power distribution network and the overhauling yield of the overhauling scheme; and optimizing the overhauling scheme by using a particle swarm optimization algorithm, wherein the particle fitness value is the overhauling yield of the overhauling scheme. Compared with the existing optimization method of the overhauling schedule of the power distribution network, the method disclosed by the invention has the beneficial effects that the optimization method is more complete and accurate in evaluating the risks of the power distribution network, and interaction of various factors is comprehensively considered, so that the overhauling scheme obtained by optimization is more scientific and reasonable, and is beneficial for effectively conducting the overhauling work and lowering the cost.

Description

Technical field [0001] The invention relates to the technical field of power distribution network maintenance. Background technique [0002] The optimization problem of the distribution network maintenance plan is a multi-objective, multi-constraint and nonlinear optimization problem. A reasonable and scientific arrangement of the distribution network maintenance plan is very important to improve the power supply reliability of users, reduce the risk of the power grid and equipment, and control the maintenance cost. significance. With the development of the power system and the launch of the construction of a strong smart grid project, the ever-expanding grid scale and the emergence of new technologies such as state maintenance and distributed power generation pose new challenges to the formulation of the distribution network maintenance plan. [0003] In recent years, domestic and foreign experts and scholars have conducted a lot of research on the optimization method of the dist...
