There is demand for a substation automation system (SAS) that is simple to integrate and provides high performance and flexibility. The increasing application of intelligent electronic devices (IEDs) with International Electrotechnical Commission (IEC) Standard 61850 capacities provides interoperability and advanced communications capabilities in substation protection, coordination, control, monitoring,...
This paper discussed the application of online monitoring system based on IEC61850 standard in the smart substation. Firstly, the functions and performance requirements of online monitoring system have been discussed, and the functional model and interface model of online monitoring based on IEC61850 have been established; Secondly, the application schema of online monitoring system has been designed...
With the fast development of the smart grid technology in china, more and more attentions were paid to the condition-based maintenance of the high voltage equipment. To realize the objectives, the standardizations of the online monitoring system hierarchy structure and function are the key steps in the development of the online monitoring system in pilot smart substation project. According to the...
The profitability pressure on utilities as a consequence of market liberalization and other influences is leading to the reconsideration of the entire secondary technology inside the substation. Possible synergies between protection, control and monitoring have to be considered. At the same time, assets have to be used in a more efficient and profitable way and an increased security of energy delivery...
