The metro power supply system has a low power factor during low load rate operation. In order to save the investment of reactive compensation devices and compensate the reactive power for the metro medium voltage power supply network in the most reasonable and economical way, the reactive power optimization scheme based on the medium voltage energy feeding device is studied. The reactive power optimization model of the metro medium voltage power supply network is built and the particle swarm optimization (PSO) is used to solve the problem. In order to verify the proposed scheme, taking a metro medium voltage power supply line as an example, PSO is applied to reactive power optimization with the objective of minimizing active power loss. The simulation results show that the reactive power compensation based on the optimization results can effectively reduce the active power loss, which verifies the feasibility, rationality, and economy of the proposed scheme.
