Abstract
In this paper
a kind of MMC-based mobile DC ice-melting device with such advantages as modularity
strong scalability
high redundancy and wide DC voltage generation is studied and it is suitable for DC ice-melting application. The operating principle of MMC for ice-melting device is analyzed firstly.Then
the main control strategy of the ice-melting device is proposed. For simplifying experimental condition
a new type of rated-current zero-power test scheme is proposed. A set of mobile MMC ice-melting device for industrial application is developed and the control strategy and the effectiveness of zero power test scheme of rated current are verified on it. The function of STATCOM is achieved successfully.
