摘要

In order to reduce the data transmission delay of intelligent substation and improve the performance of intelligent substation communication network, the data mapping method of intelligent substation based on full communication link is studied. Select the devices that follow IEC61850 standard in the station control layer and interval layer, realize the communication of all communication links at the station end of intelligent substation based on IEC61850 communication architecture, and construct the communication scheme by using Manufacturing Message Specification (MMS). Based on this, design the communication model of intelligent substation with IEC61850 and MMS in combination with IEC61850 protocol, complete the bottom communication, and provide favorable conditions for the subsequent data mapping at the station end of intelligent substation. Through SPCD (Optical Fiber Physical Loop Model) and Cable automatic search algorithm, combined with the mapping of the core service of ASCI to MMS, the data mapping of intelligent substation is realized. The experiment shows that the IEC61850 and MMS of this method are consistent, and the minimum data transmission delay of intelligent substation is 0.016s, and the communication network of intelligent substation has good performance.
