چکیده
-Electromechanical wave propagation may affcet power system protective device operation. This paper discusses the testbed development to study the electromechanical wave propagation impacts on power system dynamic behavior, and consequently impacts on protective devices including overcurrent, distance, and out-of step relays. To have a better insight, a test bed to simulate electromechanical oscillations of generator rotors has been implemented. The test cases are developed in Alternative Transients Program (ATP) considering continuum model which includes transmission capacity and uniformly distributed machine inertia in modeling the power network.

متن کاملImpact of electromechanical wave oscillations propagation on protection schemes
Major disturbances in power system can take place after power system elements such as generators, loads, or transmission lines are suddenly disconnected. Such disturbances can create so called “electromechanical wave oscillations” waves which propagate through transmission lines at much lower speed than speed of light. They can cause adverse effect on power system protective relays. In this pap...
