Device with an omnidirectional master transmitter and an apparatus for coupling the electricity distribution network with the multidirectional master transmitter

摘要

A current sensor (4) in each phase line is connected through an audio frequency level meter (5) to the actual-value input of a set-point controller (8). the output is addressed to a controlling input (9) of the transmitter (1) for adjustment of its output current. Each level meter is composed of a pref. least-squares estimate averager (5a) and a low-pass filter (5c). The set-point comparator (8a) is followed by a proportional-integral regulation amplifier (8b) with an anti-wind-up circuit preventing a second integration of the control signal in the saturation region of a limiter.
