Development of Medium Voltage Power Flow Control Device

The article is devoted to the problem of an automatic regulation of the active and reactive power flows in a medium voltage (MV) distribution network (6–20 kV). The design of the (MV) Power Flow Control Device (PFCD) has been developed and it implements a method for the vector control of network parameters. To test the adequacy of the theoretical propositions a Simulink model of a 6 kV distribution network with MV PFCD has been developed. Studies of the adjustment characteristics (voltages and currents) of MV PFCD semiconductor converters on the basis of the simulation model have been carried out. The analysis of the adjustment characteristics allows determining the phase and amplitude control laws for the voltage vector of the MV PFCD converters for the automatic control of the active and reactive power flows in the MV network.
