The Design Of Online Monitoring Software Platform

The intelligent monitoring system of substation is an important part of the smart grid.The monitoring software can monitor the operation status of the whole substation system in real time,and the software has a certain degree of accident handling capacity.At present,there are many monitoring software used in substations,but there are few monitoring projects in general.Data information statistics are not standardized,communication standards are not consistent,and unified control of networking cannot be achieved.State grid and other power companies have an urgent need for a substation online monitoring software that can unify data modeling communication standards and perfect the integration of various monitoring units.This paper designed an online monitoring software for intelligent substation.The communication protocol adopts IEC61850 international standard.The software runed at the station control layer.It can monitor the operation status of substation equipment in real time.In addition,the software operation is safe and stable in the test of substation trial operation.Firstly,the development history of substation at home and abroad is summarized.The existing monitoring software of substation has the problem of inconsistent communication standard and so on.The software designed in this paper further improves the monitoring software of substation.Solve the existing monitoring software problems.The market demand function of intelligent substation monitoring software is analyzed.The software mainly includes monitoring decision-making function,software security,standardization and other aspects,and improves the software function.Firstly,the overall architecture is designed in the design of monitoring software platform,and then the modular design is carried out.According to the specific implementation function for detailed programming operations.At the same time the database design optimization.Database modeling,partition table.Optimize stored procedure repetition information.Speeding up data processing.The knowledge base is designed and the algorithm is analyzed.Optimize the accuracy of data processing and analysis.IEC61850 international communication standard is adopted to design the communication structure of the station control layer and unify the interface standard.Making all kinds of substation equipment accessible.Through software design,real-time online monitoring,information interaction between software devices,fault alarm and other functions are realized.Testing the software platform.Through the analysis and research of lightningarrester monitoring,transformer monitoring process of operation monitoring data,comparative analysis of online and offline data.Monitoring software produces more accurate results.The monitoring error is within the national standard and it can effectively implement fault alarm.Finally,the safety,reliability and stability of the software are proved by the software running in the actual substation.
