Spletstrength of the system as the ratio between the short circuit capacity of the ac-network and the nominal power of the HVDC link. This index is valid for single infeed HVDC systems, but can be extended to multiple infeed HVDC by the so called Multiple Infeed Short Circuit Ratio (MSCR) or Multiple Infeed Effective Short Circuit Ratio (MESCR). Spletthe system strength declines. • The use of aggregate short circuit ratio (SCR) calculation methods, e.g. CIGRE TB 671, provides some insight on the likely issues. • However, actual power system performance must be confirmed by detailed modelling and simulation.
Splet29. dec. 2010 · The concept of the short circuit ratio (SCR) is an indicator used to characterize the strength of a power system. This indicator is also associated with the system short circuit capacity. The common concept of "infinite bus" (equivalent to infinite strong) is a special case of SCR = ∞.
