提出了STATCOM用于直流融冰时适合的应用范围

并提出了移动式STATCOM融冰设计的理念和设计方法。

Abstract

Two star-connected cascaded static synchronous compensators (STATCOMs) can be used to melt ice of overhead transmission lines by connecting the line between the neutral points of the two STATCOMs. The ice-melting method has the advantage of small harmonic current and footprint. The control principle of this ice-melting mode is discussed. The DC voltage fluctuation formula is derived and the cause of double frequency circulation is analyzed by the power analysis method via simulation. In order to further engineering application

the optimal selection and design of STATCOM is analyzed

and the technical parameters and characteristics are compared with traditional static var compensator (SVC) ice-melting device. The suitable range of application of STATCOM for DC ice-melting is proposed and the design philosophy and method of movable STATCOM are proposed.
