Abstract: A remote electrical energy generating and distribution system is provided wherein a plurality of combustion turbine generators are located at respective remote sites having deposits of fossil fuel. The fossil fuel is thereby converted into electrical energy for transmission to an energy utilization center or to a power grid. Electrical energy is preferably converted to DC energy at the remote sites, and is supplemented by thermoelectric energy recovered from the exhaust of the combustion turbines. Each such source of DC energy is coupled to a main transmission line by a diode coupling device for providing isolation of each source in the event of a reduction in output voltage. Local power for cooling the diode coupling device is provided by a forward conduction voltage drop within the coupling device. The DC transmission system allows each generator to be operated at any independent optional speed.

Abstract: A method and a device in an electric power network (1), comprising an active filter (4) controllable via a control input (41), for reducing disturbances generated by a disturbance source (6) located in and/or connected to the power network. A control member (8) is adapted, based on at least one first state variable (Y1i) sensed in the power network (1) and a model of the power network (1), to calculate the disturbances (X2) which occur in a second section (B--B) in the power network (1) without action from the active filter (4), to calculate a control signal (C1) such that, supplied to the control input (41), it would generate in the second section (B--B) the calculated disturbances (X2) with reversed polarity, and to generate the control signal (C1) and supply this to the control input (41). By sensing, in addition, at least one second state variable (Y2i) in the second section (B--B), the control signal (C1) can also be generated in dependence on the control deviation (DU) of the second state variable (Y2i) from a desired value (Y2R). (FIGS. 1 and 2A)
