Method of controlling compensation device for compensating ground currents in n-phase distribution system j

摘要

Compensation device (2) with controlled current sources (3, 3, 3'') conventionally is connected between the phase conductors L.sub.1.n., L.sub.2.n., L.sub.3. nn-phase distribution system (1) instead of the ground potential (5). The novel method of controlling according to the invention is characterized in that when a ground fault (6) The total compensation current (I.sub.0.n.) creates a vector sum of the individual (n) compensation current (I.sub.01. n., I.sub.02.n., I.sub.03.n.) of all controlled current sources (3, 3, 3''), with a current amplitude show the absolute value of the deviation of more than 25% from I.sub.0.n./n values, and angles (.FI..sub.1.n., .FI..sub.2.n., .FI..sub.3.n.) their phase feed values ​​differ by more than 30% compared to the angle (.FI..sub.0.n.) phase shift in total compensation current (I.sub.0.n.).
