Dynamic State Estimator Based on Wide Area Measurement System During Power System Electromechanical Transient Process
The wide area measurement system (WAMS) developed rapidly in recent years [1-3]. It has been applied to the studies on many topics in monitoring and control of power systems. But as a kind of measurement system, WAMS has the measurement error and bad data unavoidably. The steady measurement errors of WAMS have been prescribed in corresponding IEEE standard [4], but the dynamic measurement error...
متن کاملWave propagation theory in offshore applications
A frequency-wavenumber-domain formulation is presented in this paper for calculation of the Green's functions and wave propagation modes in a stratified fluid body underlain by a layered viscoelastic soil medium. The Green's functions define the solid and fluid displacements and fluid pressures due to uniform disk loads acting in either the soil or fluid media. The solution is in the frequency ...
متن کاملTestbed Study of Electromechanical Wave Propagation Impacts on Protective Devices
-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 os...
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...
