Research On Regulation And Control System Of Grid 500kV Substation In Northern Hebei

In the background of "big run" system of the STATE GRID,the regional power grid establishes gradually a integrated management model combined power grid dispatch management with monitoring control.Then the automation system of integration of dispatching and supervisory control develops rapidly in all parts of the country.In order to improve the level of dispatching operation and management in the northern Hebei Province,this paper studies the current situation and development trend of power network operation management mode and dispatching automation system.In this paper,the current situation of dispatching operation management and dispatching automation system in the northern Hebei Province are studied.Then the operation management mode for 500 kV substations is built,which is suitable for the development of the 500 k V substations in the northern Hebei Province.Firstly,this paper introduces the current situation and development trend of the operation management mode and dispatching automation system in the domestic and international power network.Then the current situation of dispatching operation management and dispatching automation system in the northern Hebei Province are studied.Furthermore,the paper puts forward the implementation conditions,design objectives,design principles and functional requirements of building the integration of dispatching and supervisory control in the northern Hebei Province.Then the implementation plan of the integration of dispatching and supervisory control is introduced in detail from the conditions,system composition,configuration and network solutions.The main technical characteristics of the integration of dispatching and supervisory control in the northern Hebei Province are analyzed including the control level of the 500 k V substation equipment.The paper points out the advantages and disadvantages of realizing the integration of dispatching and supervisory control of 500 k V substations on the network and provincial level.Finally,this paper introduces the implementation effect of the automation system of the integration of dispatching and supervisory control.From improving the quality of basic data,improving the level of benchmarking,normalization circuit breaker remote operation,shorting the time of adjustment and fault handling,double construction of dispatching data network,enhance secondary system security protection and other aspects this paper shows the application of the integration of dispatching and supervisory control automation system.The designed automation system of the integration of dispatching and supervisory control in the northern Hebei Province 500 k V substations in this paper can be integrated into the existing dispatching automation system.The system can not only meet the application requirements of control center,and adapt to the construction requirements of "big run" system.The technical support system is safe,stable,reliable,and can significantly improve the working efficiency of the dispatcher and monitor operator.
