【正文】 ing pensate device and using the line protection with the detection of the sensitive small ground current. The paper introduces and analyzes the characteristic of all kind of grounding modes about l0kV work at first. With the parison with technological and economy, the conclusion is drawn that the improved arc suppressing coil grounding mode shows a very big development potential. Then, this paper researches and introduces some operation characteristics of the arc suppressing coil grounding mode of the l0kV distribution work. And then the paper put emphasis on how to extinguish the earth electric arc effectively by utilizing the resonance principle. This paper bines the development of domestic and international technology and innovative achievement, and introduces the puter earth protection and autotracking pensate device. It proves that the improved arc suppressing coil grounding mode have better operation characteristics in power supply reliability, personal security, security of equipment and interference of munication. The application of the arc suppressing coil grounding mode is also researched in this paper. Finally, the paper summarizes this topic research. As a result of the domination of the arc suppressing coil grounding mode, it should be more popularized and applied in the distribution 4 work in the way of thinking, project and conclusions in this thesis have effect on the research to choose the neutral grounding mode not only in I0kV distribution work but also in other power system.. The basic function of the electric power system is to transport the electric power towards customers. The l0kV electric distribution is a key point that connects the power supply with the electricity using on the industry, business and dailylife. For the electric power, all costumers expect to pay the lowest price for the highest reliability, but don39。t consider that it39。s selfcontradictory in the coexistence of economy and improve the reliability of the power supply work, we must increase the investment cost of the work construction 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. KEYWORDS: power supply and distribution, power distribution reliability ， reactive pensation, load distribution The revolution of electric power system has brought a new big round construction,which is pushing the greater revolution of electric power technique along with the application of new technique and advanced equipment. Especially, the bination of the information technique and electric power technique, to great ex tent, has improved reliability on electric quality and electric supply. The technical development decreases the cost on electric construction and drive
