Causality assessment for power quality stationary disturbances

Causality assessment for power quality stationary disturbances by means of centrality index

“…In order to test the proposed method, we applied the proposed method to two real cases that had been previously studied by the Program of Acquisition and Analysis of Electromagnetic Signals of National University PAAS-UN resorting to the assessment method based on epidemiology [6]. These two cases were selected with the aim of comparing the proposed method with already existing results.…”

“…CAUSALITY IN the conditions related to them, which combined are capable of causing an specific (frequently undesirable) power quailty state [6], that can cause one or more disturbances. In this case, the system is compound by loads and feeders connected to point of common coupling.…”

“…Some of them use the orthogonal decomposition of current based on FBD's power theory [7] [8] like the method explained in [6]. The method proposed in this paper employs some of these principles, particularly the decomposition of currents and the Method of Disturbances Interaction -M D I [4], in order to determine the interaction between agents for each stationary disturbances.…”
