Dynamic Adjustment Schemes for Divisional Power Grid Structures Based on Phasor Measurement Unit
To control the short-circuit current of Shanghai power grid,220kV power system runs hierarchically and divisionally at present and the structure of the divisional power grid needs frequent adjustment.The Phasor Measurement Unit (PMU) devices can obtain dynamic bus voltage magnitude and phase angle instantaneously and simultaneously.Therefore,the operations of breaking and closing loops based on PMUs is presented,including automatically detecting whether the conditions of breaking and closing loops can be satisfied and searching for reasonable schemes of breaking and closing loops.The research on schemes of load transfer and power support from closing loops in divisional power grid is specifically proposed.Finally,the validity of the research methods are verified by the example of Shanghai power grid.
