Boštjan Bajc (2011) Server program based on the IEC61850 protocol for notifying of the electricity system state. EngD thesis.
Indispensable part in power industry is communication with intelligent electronic devices and to control and monitor them. The communication consists of a server, which is located on the device and is intended to pass the information of the device status and a client, which is communicating with a server through the communication protocol, to control and manage the device. The thesis describes the server program, which is a part of the IEC61850 server and is capable of communicating with IEC61850 client through the MMS protocol, passing the information of process variables and to executing control operations. In thesis we analyse the structure of the communication protocol and define the way of binding process variables to communication data, where we use the EBNF notation. Next we define the arhitecture of the server program, where we decided to use a combination of C and C++ programming languages. The key part of the server program requested effective serving of data and processing of client requests. The result is a working server program, which can process the control and monitor demands over the process variables, which are mapped to IEC61850 protocol.
