Research On Construction And Operation Of Intelligent Substation Online Monitoring System

With the increasing capacity of electric power industry and the increasing scale of the whole grid,the fault of the substation,which is the core of the energy transmission,will cause great loss to the whole power system.if it is not handled properly,will cause a great disaster.And it will bring very big impact on the work and life.So the study of substation on-line monitoring technology to realize the reliable and stable equipment operation condition monitoring and ensure the normal operation of electrical equipment.In the process of system construction is to realize the on-line monitoring,on-line monitoring function of all kinds of electrical equipment is the most important,and according to the different needs of the actual equipment set up monitoring points and control monitoring mode,different switch,make the information collection,processing,analysis sub module.The realization of substation system status monitoring can improve the overall level of operation and management of electrical equipment to a great extent,and improve the role of state monitoring in maintenance decision making.The on-line monitoring of transformer substation can improve the reliability and safety of all kinds of electrical equipment,and is beneficial to the improvement of social and economic benefits.This paper introduces the research status of on-line monitoring system,and introduces the principle and way of condition monitoring of the traditional substation transformer,high voltage circuit breaker and so on.Conclusion the use of neural network combined with fuzzy control method is effective way to contain gas detection and the trend of transformer oil,combining neural network and expert system is the future development trend of fault diagnosis.Then analysis the current monitoring system which used in the distributed structure,mainly through acquisition sensors,monitoring IED and the background.After the integration of the system platform to better achieve the decentralized information collection and centralized processing,and the information will be announced in a timely manner.The system can monitor well for substation.According to the characteristics of intelligent substation operation of on-line monitoring process,it will carry out the monitoring idea reliability design,scheme selection,overall architecture design and so on,and finally achieved intelligent online monitoring system based on the working state and data information platform.Finally,summary the notice in the process of implementation about the key link and points out the corresponding countermeasure to sum up the experiences of engineering.
