RIPPLE CONTROL SYSTEM FOR A SUPPLY AREA

摘要

588389 Disclosed is a ripple control system for a supply area (NS) including an arrangement for verifying the correctness of ripple control commands. The ripple control system has a ripple control command unit (RKG) which is coupled to a ripple control transmitter (RS), a monitoring control centre (UZ), a storage buffer and monitoring receivers (UE). The ripple control transmitter (RS) supplies transmissions sent by the ripple control command unit (RKG) as audio-frequency signals to the supply area (NS). The ripple control command unit (RKG) is integrated with a monitoring control centre (UZ) in a single unit. The supply area (NS) contains the monitoring receivers (UE) in a distributed arrangement which receive sent audio-frequency transmissions and store them in the storage buffer (RB). The monitoring control centre (UZ) is connected to the monitoring receivers (UE) in order to receive the transmissions stored in the storage buffer of the monitoring receivers (UE) and to compare them with the transmissions sent by the ripple control command unit (RKG).
