TB 068 1992 SC 14 WG 14.07 Guide for planning DC links terminating at AC locations having low short-circuit capacities. Part 1. AC/DC interaction phenomena.

Part I of the Guide AC/DC system interaction phenomena, discusses the effects of various aspects of interactions between AC and DC systems on the design and performance of DC schemes connected at locations where the AC system appears as high impedance. Part II : Planning guidelines, considers the impact of the interactions and their mitigation on economics and overall system performance.
