摘 要
本設(shè)計主要內(nèi)容是按照給定的原始資料，考慮經(jīng)濟、安全、先進等要求設(shè)計一個現(xiàn)代化的供電系統(tǒng)。具體內(nèi)容為：全廠負荷的分析和計算，無功負荷的分析和補償計算，變壓所所址、型式的確定，變壓器臺數(shù)、容量、型號的選擇確定，變電所主接線方案的技術(shù)經(jīng)濟比較和確定，變配電所主要的選址及布置，短路電流的計算，全廠配電系統(tǒng)設(shè)計，高壓電氣設(shè)備的選擇與校驗，繼電保護及二次接線設(shè)計等。
通過負荷的統(tǒng)計計算，可以求出按發(fā)熱條件選擇供電系統(tǒng)中各元件的負荷值，根據(jù)計算負荷選擇的電氣設(shè)備和導(dǎo)線電纜，如以計算負荷連續(xù)運行，其發(fā)熱溫度不會超過允許值。工廠計算負荷是選擇工廠電源進線一、二次設(shè)備的基本依據(jù)，也是計算工廠的功率因數(shù)和工廠需電容量的基本依據(jù)。
電力線路的二次回路可以保證一次回路的安全、可靠、經(jīng)濟運行。在繼電保護方面我采用微機繼電保護，與傳統(tǒng)的機電型繼電保護具有：可靠性高，功能齊全，調(diào)試維護方便，經(jīng)濟性好。

Abstract
The lesson of the this time design main contents is according to the primitive data that give and settle, and consider the economy, safety, advanced etc. request design a modernization of power supply system.
Concrete contents is:Whole factory analysis that carry is with the calculation, have no the power the analysis that carry with compensate the calculation, and address for change to press , pattern really settling,transformer set counting, capacity, model number certain, change to give or get an electric shock a calculation for technique economy for lord connecting the line project comparing with make suring, and change to give or get an electric shock a choice for main equipments and arrange, short-circuit electric current,whole factory electricity give system design, defend the thunder to connect the ground design.the choice of the high pressure electric appliances equipments checks with school, protecting and connecting the line the design the iso - two times after the electricity.
The covariance that pass the burden computes, can beg to press to have fever term choice power supply system inside each an electricity for of burden value, according to calculation carrying choice equipments with lacing cable, if to compute burden continue circulate, its have fever the temperature can't exceed the admission the value.Factory calculation burden is basic basis that basic basis to choose factory power supply enter the line a, two times equipments, is also a power to compute the factory factor to need with the factory the electric capacity measures.
Electric power circuit two times back track can guarantee the safety of back track once, dependable, the economy circulates.In the aspects of protecting after the electricity I adopt the tiny machine to protect after the electricity, giving or get an electric shock with traditional machine the type to protect to have after the electricity:The dependable is high, the function is well-found, adjusting to try the maintenance convenience, the economic is good.
Key phrase: Calculation burden; transformer; transformer transformer
lord adjoin line; back track two times;Tiny machine protection;
