Systems with multiple dc infeed
WebThe MESCR proposed in [ 12] defined a multi-infeed interaction factor (MIIF) to convert the capacity of all other DC transmission lines to the bus under investigation, so that it could consider the interaction between all DC rectifier/inverter stations. Webthe two dc systems is small – a so called “multi-infeed” HVDC system [1]. Multi-infeed converters either share a common ac bus or connected to buses that are electrically close. The operation of adjacent dc terminals poses serious concerns for mutual interaction following a disturbance in either dc systems or in the common ac system.
