Voltage regulation device that includes a converter for harmonic current compensation and reactive power management

A control system for a voltage regulation device, the control system comprising:

• one or more electronic processors;
• and
• an electronic storage coupled to the one or more electronic processors, the electronic storage comprising machine-executable instructions that, when executed, cause the one or more electronic processors to:
• determine a harmonic compensation signal based on frequency data, the frequency data comprising one or more harmonic components;
• determine a reactive power compensation signal based on a reactive power set point;
• and
• control a converter of the voltage regulation device based on the determined harmonic compensation signal and the determined reactive power compensation signal to provide an output compensation current to a winding of the converter, wherein the winding of the converter is configured to magnetically couple to a winding of the voltage regulation device, and the output compensation current is configured to control an amount of reactive power provided by the converter to the winding of the voltage regulation device and to reduce an effect of the one or more harmonic components.

A method of controlling a voltage regulation device that comprises a converter, the method comprising:

• determining a reactive power set point, the reactive power set point being a target amount of reactive power provided by an electrical source electrically connected to the voltage regulation device at an input node;
• determining harmonic frequency data at a load electrically connected to the voltage regulation device at an output node, the harmonic frequency data comprising one or more harmonic components;
• determining a converter control signal based on the reactive power set point and the harmonic frequency data;
• magnetically coupling a winding of the converter to a winding of the voltage regulation device;
• and
• providing the converter control signal to the converter such that the converter produces a compensation current at the winding of the converter, wherein the compensation current reduces an effect of the harmonic components and provides reactive power to the output node, and the amount of provided reactive power is based on the reactive power set point.
