Embodiment Construction
[0020] Embodiments will now be described more fully with reference to the accompanying drawings in which certain embodiments are shown. However, other embodiments in many different forms are possible within the scope of this disclosure. Rather, the following embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Throughout the specification, like reference numerals indicate like elements.
[0021] According to the invention, a Y-connection topology device STATCOM is used. Instead of using phase reactors to provide impedance to the necessary voltage difference between the grid and the MMC, transformer leakage reactance is used. Overall, this reduces component count and footprint while simplifying the overall circuit. This does not exclude the use of (smaller) filter reactors in series with any of the converter arms. A filter reactor is a reactor whose purpose ...
