摘要
Abstract
Equivalent disturbing current is used as the standard of restricting harmonic current level at DC side in HVDC project. To compute accurate equivalent disturbing current, using 3-pulse model the UHVDC power transmission project was modeled and equivalent disturbing currents under different parameters of DC filtering system were calculated, thus following rules of equivalent disturbing current varying with parameters of component parameters were attained: the equivalent disturbing current decreases with the increase of inductance value of smoothing reactor; it decreases with the increase of neutral-line-to ground capacitance; it decreases with the increase of capacity of HV capacitor of DC filter, and corresponding varying curves were obtained. Besides, the parameters of the filtering system, by which the equivalent disturbing current could meet the requirement of the allowable value, were proposed.关键词
