چکیده
Recently, high-frequency oscillation of the modular multilevel converter (MMC) based high-voltage direct current (HVDC) projects has attracted great attentions. In order to analyze small-signal stability, this paper uses harmonic state-space (HSS) method establish a detailed frequency domain impedance model AC-side HVDC transmission system, which considers internal dynamic characteristics. addition, suggested is also used assess system's mechanism, and effects MMC inner loop control, feedforward voltage links, control delay on characteristics effect higher components. Finally, three suppression schemes are analyzed for problems occurring in actual engineering, simplified considering only established compare with prove its reliability.

AC frequency characteristics of coplanar impedance sensors as design parameters.
Glass-based microchannel chips were fabricated using photolithographic technology, and Pt thin-film microelectrodes, as coplanar impedance sensors, were integrated on them. Longitudinal design parameters, such as interelectrode spacing and electrode width, of coplanar impedance sensors were changed to determine AC frequency characteristics as design parameters. Through developing total impedanc...
متن کاملComment on ‘‘AC frequency characteristics of coplanar impedance sensors
In their article, ‘‘AC frequency characteristics of coplanar impedance sensors as design parameters’’, Hong et al. present an analytical model for the calculation of the resistance between two electrodes in a microchannel. However, their measurements fit poorly with their suggested model, and they attribute the discrepancies to electrode thickness and a ‘fringing effect’. In this note we show t...

The small-signal impedance modeling of modular multilevel converter (MMC) is the key for analyzing resonance and stability of MMC-based ac power electronics systems. MMC is a converter system with a typical multi-frequency response due to its significant steady-state harmonic components in the arm currents, capacitor voltages, and control signals. Therefore, traditional small-signal modeling me...
