Delay Analysis of Multi-Link Data Exchange and Data Sharing Network in Intelligent Substations
The real-time and reliable data transmission based on IEC61850 is an important part of the intelligent substation process bus communication.All the control,protection and current/voltage signals in the intelligent substation are transmitted through network.The communication network,as information exchange hub of the intelligent substation,has played a decisive role in the control and protection of system functions,and becomes the foundation of safe and reliable operation of the intelligent substation.This paper analyzes the network transmission characteristics and delay of GOOSE,and tests the performance of system network.Emphatically,the transmission delay,store-and-forward delay,switch delay,queuing delay are studied.According to the network flow,quantitative analysis is made on the network delay which affects the intelligent substation performance.The total delay is calculated,and the validity and reliability of the GOOSE network trip method is verified.
