Embodiment Construction

[0064] Attached below figure 1 , 2 The present invention is described in further detail.

[0065] As an important component of the entire power distribution system, the power system switch plays an important role in the safety of the power distribution system and the reliability of power supply. Distribution automation is closely related to primary equipment switching. Distribution automation fault automatic isolation and network reconfiguration are all realized by remote operation of primary equipment switching by computer. The distribution automation terminal is the basic link to realize the distribution automation, and has functions such as remote signaling, telemetry, remote control, and remote adjustment. The second remote feeder terminal refers to the power distribution terminal with the functions of remote measurement, remote signaling and fault information reporting. Since it does not have the remote control function, the corresponding switch does not need an electri...

Abstract

The invention provides an optimal configuration method for feeder terminals based on an genetic algorithm, which is characterized in that an objective function is built according to the total investment of two-remote feeder terminals and three-remote feeder terminals under constraint conditions of a power supply reliability index of a power distribution network and power failure time of a load point, reliability evaluation is performed by adopting a fault consequence analysis method, influences imposed on the reliability of a power distribution system and the power failure time of a load pointby the two-remote feeder terminals and the three-remote feeder terminals are sufficiently considered, and finally the objective function is solved in an optimized manner by adopting the genetic algorithm. The optimal configuration method can solve a configuration problem in number and position of the two-remote feeder terminals and the three-remote feeder terminals, and provides a reference for scientifically and reasonably performing power distribution automation plan design and transformation.

Description

technical field [0001] The invention relates to an optimal configuration method, in particular to a genetic algorithm-based optimal configuration method for a feeder terminal. Background technique [0002] The proposal of smart grid has received positive responses from most countries in the world. Smart grid is a power system composed of distribution network and transmission network. Compared with traditional power grid, it has the characteristics of observability, controllability and automation. Through the application of communication and computer technology, the safe and reliable operation of the power grid can be realized. As a big power country, our country is also actively developing smart grids, and puts forward three technical requirements to realize informatization, automation, and interaction. The distribution network is an important part of the power grid. How to meet the requirements of the development of the smart grid and the transformation of the distributio...
