摘要：
The conventional method of calculating high-voltage direct current (HVDC) converter commutation angles can result in very inaccurate results if the ripple of the DC is fairly high, or the HVDC link consists of capacitor commutated converters (CCC). For conventional line-commutated current source converters with a high DC ripple new analytical equations are presented for determining the commutation angles and the instantaneous values of DC DCside current at the firing instants. An iterative method for the calculation of commutation angles of CCC was also developed. The results are confirmed by digital simulation.
