Possible savings in electricity transmission using wide area monitoring technologies in Croatian power transmission network

Since the economic aspect arose over the technical regarding the development of the infrastructure of electrical power systems, new guidelines and ideas began to emerge particularly in terms of control, measurement and protection of the system. This paper describes concept and functions of wide area monitoring, protection and control in the real time in order to reduce costs that could be caused by future investments in building the infrastructure of electrical power system. Also, the paper considers the aspects of implementation of renewable energy sources on the example of wind farm Vrataruša and describes the conceptual design of automatic control for that part of the power transmission network.
