| With the rapid development of China's economy and the improvement of people's living standards,users of power quality and reliability of power supply requirements are getting higher and higher,short-term power outages and voltage fluctuations are likely to cause huge economic losses,but the traditional The distribution network operation and management methods have been difficult to further improve the distribution network management level and reliability.Achieve distribution automation can improve power quality and reliability,but also can be a reasonable distribution of power and reduce losses.Site monitoring system is equipped with the core automation technology solutions,according to choose the distribution automation and with the goal of building the actual state of the grid.Distribution grid distribution automation systems need to include consideration of site monitoring main column switch,switch stations,distribution stations,as well as bench changed me change and so on.Monitoring the site,including a remote(remote communication),two remote(remote communication / telemetry),three remote(remote communication / telemetry / remote control),local control four basic implementation.Distribution point monitoring system covering the site of a city or urban part of the city,involving tens of thousands of sets of equipment,the construction process is a comprehensive enormous project,if there is no reasonable scientific technical solutions,it is hard to imagine after completion of the system can and to achieve the desired objectives.Therefore,the implementation of web sites and distribution monitoring,should pay attention to the system design,scientific and rational way to determine the goal of building systems and monitoring program for the construction of a reliable,practical,distribution automation site monitoring system lay the foundation for the economy.The issue surrounding the characteristic distribution automation monitoring program of four sites on the power supply reliability indicators in terms of the contribution made by such as expanded research and analysis,the main contents of this paper are:(1)To understand the scope of distribution automation,system architecture,site monitoring,configuration and information collection terminal functions,etc;for example,by how the communication network to achieve the operating characteristics of the power distribution between the terminals,with the concept of electronic stations,sub-stations and distribution terminals and sub-station and the main station of massive data transmission.(2)Every action research and analysis program to monitor the distribution site at the specific impact on improving reliability of power supply,as well as links between the two,including a walk,two steps,three remote and local control of these four sites monitoring program.(3)Analysis of AE five areas with the goal of building automation as well as contact the actual state of the distribution network and site monitoring program adopted between.(4)Analysis of economic development,for example G City five regions,each power supply load density zoning and indicators for power supply reliability requirements,according to the research content best suited to propose a set of basic conditions G City of distribution automation monitoring sites program.The proposed distribution automation monitoring system site selection principle,can be a good solution to the traditional distribution automation exists a lack of balanced embodiments other issues,but simple,reliable,and easy to implement,can further improve reliability,reduce investment costs,better achieve the desired results. |
