Blocking scheme in distance protection
WebJan 9, 2024 · Distance protection blocking and re-opening scheme in multi-machine power system oscillation scenes Jing Ma, Corresponding Author [email protected] … WebA fault location method is proposed because this is a prerequisite for an effective design of a fault protection scheme. It is demonstrated that it is relatively easy to evaluate the distance to a short-circuit fault using voltage reference comparison. For the more difficult challenge of locating ground faults, a method of estimating both the ...
