چکیده
This article proposes a capacitor condition monitoring (CM) method for modular multilevel converter (MMC) in motor drive applications. The proposed is based on wavelet decomposition of transient voltage signals, which independent modulation schemes and control strategies. equivalent series resistance (ESR) change can be detected with moderate computation requirement. Both simulation experimental results have verified the performance method.

Capacitor Voltage Monitoring in Modular Multilevel Converter
A Modular Multilevel Converter (MMC) is an attractive solution for power conversion without transformers. As MMC consists of cascade connections and floating dc capacitors, it requires continuous voltage monitoring. An adaptive observer design has been presented to estimate the capacitor voltages from the measurement of arm currents. This work introduces a capacitance value of the cell capacito...
متن کاملModular Multilevel Converter Based HVDC for Grid Voltage Stability
This paper proposes a control method of the modular multilevel converter based high voltage direct current (MMC-HVDC) system for the grid voltage stability instead of using a static synchronous compensator (Statcom). The d-axis current component is used to control the grid voltage via the reactive power. Meanwhile, the q-axis current component is employed to control the active power according t...
متن کاملTrade-Off Strategies in Designing Capacitor Voltage Balancing Schemes for Modular Multilevel Converter HVDC
This paper focuses on the engineering trade-offs in designing capacitor voltage balancing schemes for modular multilevel converters (MMC) HVDC: regulation performance and switching loss. MMC is driven by the on/off switch operation of numerous submodules and the key design concern is balancing submodule capacitor voltages minimizing switching transition among submodules because it represents th...

A unified power flow controller (UPFC) based on the flying capacitor (FC) multilevel voltage-source converter (VSC) topology with phase-shifted sinusoidal pulse-width modulation (PWM) control is presented. This converter allows higher power handling, potentially lower power loss, lower harmonic distortion and hence less filtering requirements when compared with the typical two-level counterppar...
متن کاملModified Modular Multilevel Converter
The modular multilevel converter (MMC) is receiving extensive research interests in high/medium voltage applications due to its modularity, scalability, reliability, high voltage capability and excellent harmonic performance. The submodule capacitors are usually quite bulky since they have to withstand fundamental frequency voltage fluctuations. To reduce the capacitance of these capacitors, th...
