Abstract: A series compensation device for an electrical energy transmission network includes a transformer. A primary winding of the transformer can be connected in series in a phase line of the energy transmission network. The series compensation device has a modular multilevel power converter which has a plurality of modules that form an electrical module series circuit. The modular multilevel power converter is connected to a secondary winding of the transformer. A series compensation method for an electrical energy transmission network is also provided.

Abstract: A system for compensating one or more DC components in an electrical system includes one or more sensors for sensing the one or more DC components. The system also includes one or more DC component controllers for generating one or more reference signals from one or more signals received from the one or more sensors. In addition to this, the system also has one or more controllers for generating one or more firing pulses from the one or more reference signals received from the one or more DC component controllers and one or more valve configurations for charging one or more controllable branches to counterbalance the one or more DC components of the electrical system. A method for compensating one or more DC components in an electrical system is also provided.

Abstract: A device for pneumatically conveying a free-flowing bulk material in a dense flow method, containing a cross-sectionally closed conveying line with a conveying channel, a compressed gas auxiliary line with a compressed gas channel, and gas passages which permit the passage of compressed gas and which serve to supply the conveying channel with a compressed gas from the compressed gas channel. A fluidizing device is assigned to the conveying line, and the fluidizing device contains a fluidizing body having a fluidizing gas channel and fluidized gas passage openings which permit the passage of fluidizing gas and which serve to supply a fluidizing gas from the fluidizing gas channel and into the conveying channel.
