【正文】 termined to be safe in order to provide satisfactory service to the power system customers. Voltage levels, line currents, and equipment loading may vary from location within a system, and control is on a relatively local basis. For example, generator voltage is determined by the field current of each particular generating unit。 and e Iamp。Power Supply and Distribution System The basic function of the electric power system is to transport the electric power towards customers. 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 drives innovation of electric work. On the basis of national and internatio nal advanced electric knowledge, the dissertation introduces the research hotspot for present electric power sy etem as following. Firstly, this dissertation introduces the building condition of distribution automation(DA), and brings forward two typical construction modes on DA construction, integrative mode and fission mode .It emphasize the DA structure under the condition of the fission mode and presents the system configuration, the main station scheme, the feeder scheme, the optimized munication scheme etc., which is for DA research reference. Secondly, as for the (DA) trouble measurement, position, isolation and resume, This dissertation analyzes the changes of pressure and current for line problem, gets math equation by educing phase short circuit and problem position under the condition of singlephase and works out equation and several parameter s Uamp。 , s Iamp。 table on problem . 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
