Experimental analysis and modelling of an information embedded power system
Maung Than Oo, Amanullah (2007) Experimental analysis and modelling of an information embedded power system. PhD thesis thesis, Victoria University.
As power industry enters the new century, powerful driving forces, uncertainties and new functions are compelling electric utilities to make dramatic changes in their information communication infrastructure. Expanding network services such as real time measurement and monitoring are also driving the need for more bandwidth in the communication network and reliable communication infrastructure. These needs will grow further as new remote real-time protection and control applications become more feasible and pervasive. Information embedded power system via wide area network (IEPS-W) is the solution to accommodate the growing demand of wide area monitoring, protection and control. IEPS-W is an extension of traditional power systems with added monitoring, control and telecommunications facilities. Various power system communication protocols are being used within IEPS-W to transmit critical data in real time along with decades old Supervisory Control and Data Acquisition System (SCADA). Most of the protocol in used are not originally developed to use in wide area computer network (WACN) environment. However, protocol developers upgrade their protocols and use it in WACN. This requires experimental investigation of various power system communication protocols before employing it on the power grid. An experimental platform was set up at Victorian Network Switching Centre owned by SP AusNet PTY LTD (an Australian Transmission and Distribution company based in Victoria) in order to experimentally analyse the performance characteristic of Distributed Network Protocol (DNP3) over wide area network (WAN). In this experiment, real time data were sent from Intelligent Electronic Devices to utility control center using WAN. Experimental work reveal that measurement delays associated with DNP3 over WAN is high, as this type of network is much more complex due to the added complexities of routing and switching. This requires further development of DNP3 protocol to be reliably used in IEPS-W. Hence, DNP3 was further developed using Optimized Network Engineering Tools (OPNET). OPNET is the industry‘s leading simulator specialized for network research and development. Finally, a new protocol has been developed based on DNP3 protocol to reliably and securely transmit power system data for IEPS-W.
