Research on Substation Communication Power Supply Monitoring Based on MODBUS Protocol and IEC 61850 Protocol
Because the existing substation power supplies are generally independent of each other,the communication protocols between systems are incompatible with each other,and it is difficult to share information.In order to solve the above problems and realize intelligent monitoring of substation power supply,a monitoring method of substation communication power supply based on MODBUS protocol and IEC 61850 protocol is proposed.The system uses IEC 61850 protocol to standardize the data of substation communication power supply system,and realizes the conversion between different communication protocols through software conversion module to monitor different power supplies of substation in real time.The test results show that the substation power monitoring system can realize the communication between charger and battery management system,inverter and IEC 61850,and effectively solve the problems of difficult data sharing and incomplete monitoring information in the existing power monitoring system.
