The use of synchronized vector measurement technology based on high-precision measurement of electrical regime parameters at various points of the EPS can significantly increase the observability of the processes occurring in the power system. Real-time visualization of the SVM makes it possible to achieve an increase in situational awareness of operational dispatch personnel, both in dispatch centers and at individual power system facilities, allowing responsible persons to respond faster to disturbances that arise in the system. The existing systems for data collection and operational dispatch control of both foreign and domestic manufacturers allow visualization of SVM both at the pace of the process and after the fact, keeping retrospective data, in case of disturbances in the EPS. The main visualization methods, as a rule, include: the use of contours (gradient display) of EPS characteristics (voltage angles, power flows in the system, etc.), the placement of pie charts and indicators to display bus voltage, load power lines, etc. and the use of combined indicators for displaying the direction of power flows in the system. Among the key trends in the field of visualization of measurement information for dispatching personnel, it is worth highlighting the increase in the representativeness of the system state due to a higher data update rate within the framework of the visualized EPS model and the identification of emergency conditions due to the processing of incoming data streams from PMU at the pace of the process with subsequent alarm formation for the dispatcher.
