Description

Implementation of a real time wide area monitoring system using synchrophasors, which monitors, records and stores measurements from critical locations (generating stations and main load centers) is very important for a power system. The synchrophasor technology is implemented very successfully to prevent the system-wide blackout in United States of America, Canada, China, India, and in many European countries. The information collected and monitored from all around the system will be helpful to analyze any short term or long-term events. This technology is very useful in the Control Center to monitor the real time behavior of the power system efficiently, and with better visualization compared to the existing SCADA (Supervisory Control and Data Acquisition) system due to very high resolution of the available system data. With synchrophasor technology, it is easy to analyze the disturbance throughout the country due to common GPS satellite global reference time signal. In addition, this information will be useful to pin-point the root causes and make corrective actions to prevent such events in the future. Furthermore, implementation of such monitoring system is beneficial to evaluate, retune and modify very important devices such as controllers and protection systems. The presentation was focused on the applications of synchrophasors in power system applications. Several practical examples were discussed .
