Submodule capacitance monitoring approach for the MMC with asymptotically converged error
To reduce noise interferences and improve the steady-state estimation accuracy of
submodule (SM) capacitors, a novel SM capacitance monitoring approach has been
proposed for the modular multilevel converter in this article. First, the fundamental frequency
(FF) component is analyzed to be dominant of the capacitor voltage squared. Then, based
on the energy equation W= Cv 2/2, half of the FF capacitor voltage squared is selected as
the input variable, and the FF capacitor energy calculated by power integral is selected as …
