Distribution network connection method

Abstract

The invention relates to a distribution network connection method and belongs to the distribution network method technical field. The distribution network connection method adopts that a primitive connection type is the basic unit of the distribution network transmission electric energy; a point-to-point connection type from a power supply to a load comprises an overhead primitive connection and a cable primitive connection. The distribution network connection method identifies the types and magnitudes of the primitive connection, forms the distribution network connection method in an inferring mode, and accesses the types of the distribution network connection. The appraisal types of the distribution network comprise a reliability access, an economic access, and a security access. The distribution network connection method chooses an optimized connection model, introduces obscure subordinating degree function to solve the problem of inconformity of all kinds of index dimensions, and achieves selecting the optimized connection type under different emphasis through dynamic weighting. The distribution network connection method has the advantages of avoiding a former inherent flaw of the connection type, improving the security index, an obscure subordinating degree and a weighting thought, providing novel synthetic evaluation module for the distribution network connection, and has a significant practical value and referential meaning on construction of the distribution network by introducing an obscure inference method to constitute the distribution network connection type.

Description

technical field [0001] The invention relates to a novel distribution network connection method, in particular to the planning of the distribution network connection mode, the reliability, safety and economy of the operation of the power network, and belongs to the technical field of distribution network methods. Background technique [0002] In recent years, in order to adapt to the rapid growth of load and the continuous improvement of users' requirements for power supply, my country is planning and transforming urban distribution networks. Among them, the modular wiring of distribution networks is a very important issue. It not only involves The economy and reliability of power grid construction are conducive to the realization of automation, and it is of great significance to the development of the entire power industry and economic development. Therefore, how to choose the optimal connection mode and realize the reasonable planning of the distribution network has become a...

Problems solved by technology

But generally speaking, the current distribution network connection method and evaluation system still have some shortcomings: planners can only choose one of the traditional connection modes as the optimal connection for the planning area, and cannot avoid the traditional connection mode. Defects; Although the security analysis of the distribution network can be quantitatively analyzed with a set of indicators, these indicators can only be applied to the radial distribution network connection mode, and the traditional index evaluation system does not consider the distribution network. Safety issues; the traditional index evaluation system only calculates the specific values ​​of reliability and economical indicators for specific wiring methods, and cannot evaluate the overall advantages and disadvantages and adaptability of different wiring methods
