Electrical network takes a role of the bridge between producing -electrical energy enterprises and users, it is well known that electrical network is also important for the stability and reliability of power supply. The design of power system acts as important one aspect in the construction of electrical network, witch must be given an extra attention. This paper concisely has introduced method and the process of the distribution net design of regional power grid. It should be according to the related information of user loads, each distribution station site and the condition of power supply of existed power plants, making corresponding power balance, and then determine every distribution transformer capacity and number. According existing knowledge and experience, imagine two kinds alternative scheme, compare through technical economy from some aspects, making sure the best scheme for the selection of the design schemes. Finally to the best scheme flow calculation, according to its results we should assess the surge plan requirements of the optimum scheme, and select the final surge plan. Key Words: power flow calculation, voltage regulation scheme, network connection program 目录 目录 目 录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc356051408 第1章 引言  PAGEREF _Toc356051408 \h 1  HYPERLINK \l _Toc356051409 1.1 选题背景  PAGEREF _Toc356051409 \h 1  HYPERLINK \l _Toc356051410 1.2 研究目标和意义  PAGEREF _Toc356051410 \h 1  HYPERLINK \l _Toc356051411 第2章 设计题目和原始资料  PAGEREF _Toc356051411 \h 2
