متن کاملImproving Monitoring, Control and Protection of Power Grid Using Wide Area Synchro-Phasor Measurements
When disturbances occur in power grid, monitoring, control and protection systems are required to stop the grid degradation, restore it to a normal state, and hence minimize their effects. However, in wide area power grid resulting from large extension and interconnection with neighbor grids, classical systems based on local independent measurements and decisions are not able to consider the ov...
متن کاملIdentifications and Monitoring of Power System Dynamics Based on the PMUs and Wavelet Technique
Low frequency power oscillations may be triggered by many events in the system. Most oscillations are damped by the system, but undamped oscillations can lead to system collapse. Oscillations develop as a result of rotor acceleration/deceleration following a change in active power transfer from a generator. Like the operations limits, the monitoring of power system oscillating modes is a releva...
