摘要:隨著工業(yè)的發(fā)展以及用電需求量的不斷增加電力系統(tǒng)主電網(wǎng)的規(guī)劃顯得日益重要，它關(guān)系著用戶能否得到可靠優(yōu)質(zhì)的電能也關(guān)系著生產(chǎn)力的發(fā)展。

　　 本設(shè)計根據(jù)原始資料提供的電源信息、負(fù)荷信息以及地理信息做出相應(yīng)的功率平衡，確定電壓等級，確定發(fā)電廠變電站主接線、變壓器臺數(shù)及容量，按經(jīng)濟截面選擇備選方案導(dǎo)線，從機械強度、載流量、電壓損失等方面確定導(dǎo)線型號，然后根據(jù)電能損耗、線路投資以及年計算費用進(jìn)行技術(shù)經(jīng)濟比較，確定最終方案。

最后根據(jù)最終方案的潮流計算結(jié)果選定調(diào)壓方案。本設(shè)計給出所選方案的主網(wǎng)接線圖及潮流分布圖。

ABSTRACT:Along with the development of the industry and the increasing electricity demand of electric power system of the main grid planning is increasingly important, it was about whether the user can get reliable high-quality electricity also relationship with the development of productive forces.

　　　This design according to the information of original data provided by the power supply, load and power balance of the geographic information accordingly, determine the voltage grade, determine power plant substation main wiring, sets and the capacity of transformer, according to the economic section choice alternatives conductor, from the aspects such as mechanical strength, carrying capacity and voltage loss conductor type is determined, and then according to the electric energy loss and line investment costs of computing and technical and economic comparison, to determine the final plan according to the final solution of power flow calculation results regulating scheme is selected. This design gives main wiring diagram and the trend of the distribution of the selected scheme.

Keywords: Main grid   Power flow calculation   Surge tank scheme
