What is the difference between phasor measurement unit (PMU) blocks in Simulink?
- What is the basic algorithm inside this block - https://www.mathworks.com/help/physmod/sps/powersys/ref/pmupllbasedpositivesequence.html?s_tid=srchtitle (PMU (PLL-Based, Positive-Sequence))? Does it follow the P or M Class filter paradigm defined in C37.118?
- There seems to be one other PMU block introduced in R2020a: https://www.mathworks.com/help/releases/R2020a/physmod/sps/ref/phasormeasurementunitpmuthreephase.html (Phasor Measurement Unit (PMU, Three-Phase)). I cannot find any information on this block's algorithm either.
