Research on dynamic reactive power balance control based on comprehensive metro monitoring
Based on the phenomenon that the power factor of the public connection point(PCC)of certain urban rail transit power supply systems is less than 0.9,by analyzing and researching the generation of reactive power,compensation capacity,and compensation methods,Guangzhou metro line 10 utilizes networked dynamic balance control methods based on integrated monitoring for bidirectional compensation.In doing so,it compensates for inductive reactive power when the system is capacitive and compensation for capacitive reactive power when the system is inductive,thus ensuring that the system does not overcompensate.The results of this operation prove that this method not only eliminates harmonics,avoids resonance risks,and improves power quality,but also improves the operational stability of the metro system.This serves as a useful reference for similar engineering processes.
