AUTOMATIC AC BUS VOLTAGE REGULATION FOR POWER DISTRIBUTION GRIDS |
摘要 |
A system for automatically regulating voltage on a distribution-level AC bus having an actual voltage and a nominal voltage includes an electronic power converter connected to the distribution-level AC bus. The system generates a feedback signal representative of the actual voltage of the distribution-level AC bus and produces an input control signal in response to the feedback signal. The input control signal is representative of a commanded level of reactive power. The electronic power converter is responsive to the input control signal to deliver a commanded reactive power output to the distribution-level AC bus, and the commanded reactive power output pushes the actual voltage towards the nominal voltage. |

1. A system for automatically regulating voltage comprising:
an AC bus voltage controller in communication with a distribution-level AC bus connected to a power distribution grid and having an actual voltage and a nominal voltage, the AC bus voltage controller being configured to generate an input control signal based on a feedback signal representative of said actual voltage of said distribution-level AC bus, a droop signal and a reference signal representative of said nominal voltage, said input control signal being representative of a commanded level of reactive power; and an electronic power converter connected to said distribution-level AC bus, wherein said electronic power converter is responsive to said input control signal to deliver a commanded reactive power output to said distribution level AC bus and said commanded reactive power output pushes said actual voltage towards said nominal voltage.
