SCADA systems that are used nowadays for the monitoring purpose of power system are becoming inefficient for dealing with many specific problems happening in the grid. The post disturbance analysis cannot be efficiently done using the SCADA. The introduction of PMU technology provides a greater perspective about the grid monitoring and post event analysis. The disturbances that have affected the power...
The present system used for the monitoring and control of grid is the Supervisory Control and Data Acquisition System (SCADA). It has been observed that dynamic visualization of power system cannot be achieved effectively by the use of the SCADA system because of the low sampling rate. But, paradigm shift in grid monitoring, online fault detection and offline post disturbance analysis can be achieved...
The issues regarding a huge quantum of measurement data to the Phasor Data Concentrator (PDC) at a very fast rate due to the installation of multi-channel PMUs in the power sector deserves significant attention from the utility and operators point of view. PMUs usually have a high reporting rate of 50 frames per second. The number of phasor parameters that can be send to the control centers are limited...
