12.1.2 Functionality
The multi-purpose filter function block, SMAIHPAC, is arranged as a three-phase filter. It has very
much the same user interface (e.g. inputs and outputs) as the standard pre-processing function
block SMAI. However the main difference is that it can be used to extract any frequency
component from the input signal. Thus it can, for example, be used to build sub-synchronous
resonance protection for synchronous generator.
