Problems solved by technology

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
[0004] Especially in the distribution network planning of the planning and construction area, the planning and construction area refers to the development in progress without the detailed control regulations of the local government, but the power load in the area increases rapidly

Embodiment Construction

[0064] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0065] Take the transformation and construction of the distribution network in the planned development area of ​​Yunnan Province as an example.

[0066] The distribution network in the built-up area is between the distribution network in the built-up area and the distribution network in the natural development area, and it can be used as a transitional stage for power distribution in the built-up area. In the case where the government has a clear plan, the grid planning method can be considered to plan the distribution network; Describe this method in detail.

[0067] 1. Bottom-up planning method of distribution network in construction area

[0068] In recent years, there have been a series of problems such as sudden increase in electricity load in tourist attractions, overloaded operation of distribution ...

Abstract

The invention provides a construction area distribution network planning method and system. The method comprises the following steps of: (1), carrying out status analysis; (2) giving a power demand prediction result of a planning area by adoption of bottom-to-top point load prediction and space load prediction combined method; (3) carrying out distribution transform platform planning; (4) carrying out medium-voltage line planning; (5) carrying out project booking; (6) carrying out investment estimation; and (7) giving suggestions to a superior power grid. Aiming at planning and construction areas, a bottom-to-top planning method is adopted, so that the applicability of distribution network planning is practically improved, and the refinement, differentiation and standardization levels of distribution network transformation and construction are furthermore strengthened.

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 construction 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 pow...
