【正文】 s selfcontradictory in the coexistence of economy and reliable. To improve the reliability of the power supply work, we must increase the investment cost of the work con struction But, if the cost that improve the reliability of the work construction, but the investment on this kind of construction would be worthless if the reducing loss is on the poweroff is less than the increasing investment on improving the reliability .Thus we find out a balance point to make the most economic, between the investment and the loss by calculating the investment on power and the loss brought from poweroff. The thesis analyses on the economic and the reliable of the various line modes, according to the characteristics various line modes existed in the electric distribution in foshan.. First, the thesis introduces as the different line modes in the l0kV electric distribution and in some 7 foreign countries. Making it clear tow to conduct analyzing on the line mode of the electric distribution , and telling us how important and necessary that analyses are. Second, it turns to the necessity of calculating the number of optimization subsection, elaborating how it influences on the economy and reliability. Then by building up the calculation mode of the number of optimization subsection it introduces different power supply projects on the different line modes in brief. Third, it carries on the calculation and analyses towards the reliability and economy of the different line modes of electric distribution , describing drafts according by the calculation. Then it makes analysis and discussion on the number of optimization subsection. At last, the article make conclusion on the economy and reliability of different line modes, as well as, its application situation. Accordion to the actual circumstance, the thesis puts forward the beneficial suggestion on the programming and construction of the l0kV electric distribution in all areas in foshan. Providing the basic theories and beneficial guideline for the programming design of the lOkV electric distribution and building up a solid , reasonable layout, qualified safe and efficientlyworked electric distribution .

It brings out optimized isolation and resume plan, realizes auto isolation and work reconstruction, reduces the power off range and time and improves the reliability of electric power supply through problem self diagnoses and selfanalysis. It also introduces software flow and use for problem judgement and sets a model on work reconstruction and puter flow. Thirdly, electricity system state is estimated to be one of the key techniques in DA realization. The dissertation remends the
