Development area distribution network planning method and system

Abstract

The invention provides a development area distribution network planning method and system. The method comprises the following steps of: (1) status analysis: finding out weak links of administrative village distribution networks through arranging and analyzing data of the administrative village distribution networks; (2) a load prediction method; (3) an administrative village distribution network transformation and construction scheme: forming a uniform village distribution network transformation and construction scheme from the idea of overall planning to solve the existing problems in the administrative villages; and (4) investment estimation: carrying out project investment estimation on each single project in a project library according to investment estimation control unit price conditions. According to the method and system, administrative villages are taken as units to form a plan that one village has one scheme about distribution network, the problem solution scheme is integrally considered from the global angles of transformer substation, 10kV circuit, distribution transform platform and low-voltage circuit, and different from the existing single-point problem solution scheme, the scheme is capable of effectively avoiding the problems of mass-demolishing mass-construction and repeated construction, and enhancing the economic benefits of power grids on the basis of problem solution.

Description

technical field [0001] The invention belongs to the field of power system distribution network, and in particular relates to a distribution network planning method and system suitable for development areas. Background technique [0002] As the last link from the power system to users, the power distribution link has the closest relationship with users and has the most direct impact on the overall performance efficiency of the system and the quality of power supply for users. Therefore, in order to truly achieve "customer-centric" and improve service levels, a reliable distribution network must be supported. However, for a long time, my country's distribution network investment has been insufficient, resulting in a weak distribution network foundation, low reliability, and high line loss rate. [0003] In order to effectively improve the overall level of the distribution network, it is necessary to start from the technical level. On the basis of detailed analysis of the powe...

However, for a long time, my country's distribution network investment has been insufficient, resulting in a weak distribution network foundation, low reliability, and high line loss rate

[0003] In order to effectively improve the overall level of the distribution network, it is necessary to start from the technical level. On the basis of detailed analysis of the power supply requirements of different regions and different types of users, research and formulate the technical development route and goals of the distribution network. However, the current transformation and construction mode There are still some deficiencies and room for improvement in the support of "differentiated" planning goals, "standardized" construction types, and "refined" management
