The intelligent substation bay equipment communicates with the monitoring background and remote control network shutdown using the IEC 61850 MMS model and protocol.The MMS information model is complex,with a wide range of service contents,and there are problems such as large MMS information volume and low debugging efficiency.This article proposes an intelligent station debugging technology based on MMS simulation,studies the communication and service simulation of MMS data sources,and develops an MMS simulation debugging system.By simulating the MMS client to monitor and view the device information of the station control layer,the MMS server sends protection and measurement and control information to the monitoring master station,responds to the command of the master station,and achieves MMS communication anomaly debugging,protection information debugging,control master station point-to-point debugging,and closed-loop automatic testing based on MMS simulation.The practical application of this technology has shown that it can effectively improve the efficiency of MMS information debugging in intelligent substations,ensuring the timely and reliable operation of intelligent substations.
