Distribution Network Scheduling The Auxiliary Support Development And The Development Of The System,

Smart grid represents the general research trend of power systems and serves as a comprehensive solution in tackling energy shortage, environmental pollution, and climate change, economic and sustainable development challenging human beings. Cooperation and collaboration of system become more and more important. In addition, with the development of renewable technology, renewable power systems are growing rapidly because of their cleanness. Distribution network scheduling support essential to ensure the system power distribution system reliability, high performance and high power quality, power system operation to achieve security, stability and economic performance.As distribution network connection between transmission network and consumer's facilities, distribution network has been paid more and more attentions to its planning. So distribution automation is more and more important.Based on above background, this paper introduces the characteristic of distribution network scheduling support system design and the application method. Firstly, the development status of distribution networks and correlative matters are analyzed. Then a dispatch support system of distribution networks which has eight main functions that are the facility parameters recording function basing on graphic and model integration technology, which is include automatic drawing, automatic generation of topology, automatic database associated, measurement points marked automatically, the correctness of the school co-graphic generated automatically, the facility state intelligent displaying function, which is virtual expression through visual equipment to meet the subdivision operation mode, in-line with a pie chart, color dashed, solid line, gray, adding to other display means shows the location substation equipment with a different variety of icons status, and view the specific information, such as the specific state of equipment out planned maintenance, protection action. The function is creating, referring, and inversing of preparing case basing on graphic and model integration technology. The intelligent work relieving recording function, which is graphics library can define and generate the distribution network model, which can include all the various distribution network equipment, power distribution system transformers, circuit breakers, the recloser, Sectionalized, column load switch, ring main units, voltage regulators , Reactive power compensation capacitors. The risk and weakness location evaluating and prompting function, the WEB promulgating function, and the history incident checking and reporting function, is designed based on visualization technology. At last, it is applied and verified in the actual system that shows that it would be a reference to intelligent electric power grid construction.
