I have more of a discussion type question than one about Electrical Concepts (though I suppose it will devolve into that area). I've been doing a bit of reading about settingless relaying schemes and was wondering how they really improve over the traditional methods?
The method of Dynamic State Estimation seems to do precisely the same thing as any other differential protection scheme, except it looks to be better at detecting high impedance faults.
Simplicity is beautiful, and, in many areas, superior to the obfuscation that "new technology" tends to introduce. If protection schemes are meant be as simple as functionally possible, would it be entirely prudent to complicate the methods by introducing State estimation and communication between remote areas? Thoughts?
