METHOD OF MEASURING POWER CIRCLE DIAGRAM AND POWER MARGIN BASED ON REAL-TIME DATA AND POWER MONITORING SYSTEM USING THIS METHOD

摘要

The present invention relates to a technique for monitoring the transmission power by receiving the pager data from the transmission and substation in real time to calculate the power circularity and the active power margin. The present invention includes the steps of acquiring time-synchronized pager data from a data transmission apparatus installed in power transmission and reception substations, calculating circle diagrams at power transmission and reception substations based on the acquired time synchronization pager data, and the calculated circle diagram. Computing the margin of the active power using the. Thus, it is possible to monitor the power system in real time and operate the system with improved reliability.
