Application Of Intelligent Dispatching Technology In Guangzhou Power Distribution Network

With the rapid development of national economy and the increasing improvement of national living standards,various types of electrical appliances are constantly emerging,people are increasingly inseparable from electricity.In the continuous renewal of power supply and transmission equipment,the management of power grid business also needs corresponding changes.Distribution network as a terminal link of power transmission directly facing customers,the reliability of distribution network power supply directly affects the user's experience of electricity consumption,distribution network security,reliable and efficient operation has gradually become the focus of power supply enterprises.Among them,as the commander of distribution network operation and fault handling,the safe and efficient operation of distribution network dispatching business is closely related to the safe and reliable power supply level of distribution network..Distribution network is a large-scale,complex structure and frequently changed network.The complexity of distribution network structure determines the high risk of its operation.Then,the technical support of distribution network dispatching is often neglected,resulting in the backward technical support level of real-time dispatching operation of distribution network.Especially when the dispatching business of distribution network is increasing rapidly and the dispatchers are insufficient,it is urgent to develop intelligent dispatching technology to improve the efficiency of dispatching operation of distribution network.In this paper,the characteristics of Guangzhou distribution network dispatching and operation business,in order to improve the efficiency of distribution network dispatching and operation,the application of distribution network intelligent dispatching technology is studied.By analyzing the characteristics of Guangzhou distribution network dispatching business of fault disposal and planned overhaul,this paper discusses the establishment of the accounting basis for the application of intelligent dispatching technology from the aspects of the components,data sources and construction methods of distribution network dispatching accounts,and puts forward a complete accounting basis for the construction of intelligent dispatching platform of distribution network.Standard.On this basis,this paper discusses the application of intelligent technology support in fault disposal dispatching service,planned maintenance dispatching service and dispatching service connection.In the aspect of fault disposal,the alarm and action sequence of switching fault tripping in distribution lines are analyzed,the fault alarm information of SCADA system,the switch position information and the voltage information of distribution transformer in metering automation system are read and synthetically judged,and the discrete fault alarm,switch position change and voltage loss information are integrated into one.In the case of large area power failure caused by abnormal main network,this paper discusses how to quickly generate the logic of distribution network relay strategy by technical means combining with real-time operation mode,real-time load,historical load and the load-bearing capacity of main distribution network equipment,and analyzesthe planned overhaul business.The characteristic of repair business is that discrete scheduling behavior is integrated into a complete dispatching event,and the application of intelligent agent execution technology is further discussed.In the connection of dispatching business,the existing problems of dispatching business connection mode of distribution line side transmission are analyzed,and the thinking of constructing distribution line side network dispatching application is expounded.Road and safety precaution measures.Fundamentally improve the distribution network intelligent dispatching technology level,to solve the Guangzhou distribution network dispatching after the implementation of intensive management of business bottlenecks.
