Abstract

This paper employs a Kalman filter (KF) algorithm to estimate the capacitance of submodule (SM) capacitors in modular multilevel converters (MMCs). The proposed method can be used in the health condition monitoring technique of the capacitors. This proposed scheme estimates the capacitance of each individual capacitor from data of arm current and the corresponding voltage across the targeted capacitor. The arm current is used to calculate the capacitor current from the upper state of the SM switch. The proposed method has shown very good performance under normal operating conditions. The effectiveness of the proposed technique is validated via a MATLAB simulation analysis of a single-phase four-level MMC.
