Design And Implementation Of Simulation System For Relay Fault Analysis And Setting Management

With the continuous development of China's economy and society,all walks of life require more and more stable power supply.At the same time,with the deepening of power system reform,State Grid Corporation of China accelerates the transformation from extensive management to fine management,which all put forward higher requirements for the safe and stable operation of the power grid.In the power system,relay protection is an important measure to automatically open the corresponding circuit breaker to isolate the fault and ensure the safety of the power grid.Relay protection device is the core component of power grid,and the operation management status of relay protection device also reflects the management level of power supply enterprises.Therefore,it is more and more important to give full play to the role of relay protection device,improve the quality of power supply,and do a good job of relay protection fault analysis and setting management.With the advent of information society,it is an inevitable trend for power supply enterprises to further adapt to the development of the new era to integrate the analysis and management of relay protection faults into the information management mode.On the basis of fully understanding the background and significance of relay fault analysis and setting management,this paper analyzes the research status of relay fault analysis and setting management at home and abroad.By means of field investigation,the main problems existing in the current traditional relay protection fault analysis and setting management are summarized,and the overall design scheme of the software is put forward for the specific problems.At the same time,after referring to the calculation method used in traditional fault simulation,a set of fault simulation calculation method combining the advantages of dynamic method and semi dynamic method is designed and put forward,and the calculation speed is greatly improved through the verification of calculation examples.During the development of the simulation system of relay protection fault analysis and setting management,the mainstream technology in the field of software engineering is used.Visual Studio 2010 is used as the system development tool,and C / S structure mode,MVC framework and WPF technology are used to design and develop a simulation system of relay protection fault analysis and setting management by using SQL Server 2008 database and IIS server.The friendlyhuman-computer interface design is completed,which improves the efficiency of relay protection fault analysis and setting management,and improves the operation efficiency of the software.It has certain research significance and market application prospect.In this paper,a simulation software of relay fault analysis and setting management is designed and implemented,and several modules are designed.The automatic management mode is used instead of the traditional manual management mode to realize the intelligent management of relay fault analysis and setting management.Up to now,the relay protection fault analysis and setting management simulation system has been successfully put into operation and completed the construction goal of the system.It can basically meet the technical and business requirements of users for the relay protection fault analysis and setting management,has good popularization,and has accumulated valuable work experience for the later relay protection fault analysis and setting management.
