An apparatus for dynamic load flow control in high-voltage networks has at least one phase conductor and first high-voltage connection for connection to each phase conductor. Each first high-voltage connection has first and second core sections of a closed magnetic circuit and first and second high-voltage windings surrounding respective core portions and connected in parallel. The core portions and windings are in a tank filled with ester fluids. At least one saturation switching branch outside the tank saturates the core sections and has controllable power semiconductor switches. A control unit controls the power semiconductor switches. The first and second high-voltage windings are connected at high-voltage ends to associated first high-voltage connections and at low-voltage ends to respective saturation switching branches. The device is connectable in series into the high-voltage network, with the saturation switching branches electrically insulated from ground potential.

A device for compensating for vibration and/or material stress of a component of a high-voltage system filled with a viscous medium includes a piston and a housing. A first end piece of the piston may be coupled to the component of the system. A second end piece of the piston may be at least partly within the housing and enclosed thereby, enabling movement of the piston and the housing in opposite directions along an axis. The second end piece may be coupled to an inner wall of the housing by at least one spring. The piston and the housing are surrounded by the medium filling the system. A method and computer program product for computer-aided design of a device for compensating for vibration and/or material stress of a component of the system filled with a viscous medium are also provided.

A method determines the overload capacity of a high-voltage device. The method includes creating a load forecast request for a predefined time period, determining an operational state of the high-voltage device by obtaining state parameters, transmitting the load forecast request and the state parameters at a request time to a load-forecasting model, and determining the maximum utilization in the predefined time period by the load-forecasting model, with which the overload capacity of a high-voltage device can be fully exploited. A lifetime consumption of the high-voltage device before the request time is derived from measured values by obtaining an actually consumed lifetime and the actually consumed lifetime is fed to the load-forecasting model as a state parameter. The load-forecasting model then determines the maximum overload capacity depending on the actually consumed lifetime.

In order to create a full variable shunt reactor having two magnetically controllable high-voltage throttles which is compact and at the same time can also provide capacitive reactive power, auxiliary windings are used which are inductively coupled to the high-voltage throttles. The auxiliary windings are connected to at least one capacitively acting component.

A converter station for the transmission of electrical power has a diode rectifier with a DC terminal and an AC terminal. At least one transformer is connected to the AC terminal. In order to render the converter station as compact as possible, the diode rectifier is arranged in an insulating material.

A gas turbine arrangement, a power plant having such a gas turbine arrangement and a method for operating the power plant are provided. A compressor may be mechanically coupled to a turbine which can be driven by combustion gases, such as can be generated by combustion of fuel with the compressed combustion air. An exhaust system may be used to discharge the combustion gases. One or more thermoelectric generators may be thermally coupled to the exhaust system for generating electrical energy from residual heat of the combustion gases which pass in the exhaust system. This gas turbine arrangement allows waste heat from the combustion gases to be utilized and thus the overall efficiency of the gas turbine arrangement can be increased and pollutant emissions may be lowered.

Electric fields control an electric combustion. Plasmas are created by a dielectrically impeded discharge. At least one part of the fuel is mixed with water vapor in the supply line and is subjected to a plasma discharge in a compact reactor that is in close contact with the burner in terms of reaction kinetics. In the associated device, a plasma reactor for creating a reactive plasma gas with at least one supply line for the fuel gas-water vapor mixture and an electric energy supply is integrated into the burner. The device provides suitable flow guidance of the fuel gas-air mixture, of the fuel gas-water vapor mixture, and of the reactive plasma gas.

For monitoring a combustion process in an internal combustion engine wherein a fuel-air mixture is ignited with a high-frequency plasma it is provided to determine the impedance of the plasma. A high-frequency signal is applied to the resonator with a capacity that is so low that no arcing-over forms on the electrodes and the high-frequency current and the high-frequency voltage are measured. The impedance of the ignited mixture is determined from the high-frequency current and the high-frequency voltage.

A barrier system for a line leadthrough in an electric installation has mutually adjacent wall elements forming barriers that extend in an axial longitudinal direction and are spaced apart from each other, forming channels. The wall elements lie partially on a support, at least at their lower ends. The wall elements are joined by a plug element to the leadthrough. Slots having a width which corresponds to the wall thickness of the wall elements are arranged in the plug element. The wall elements can be inserted into the slots, thus permitting a barrier system to be quickly and easily assembled and disassembled.

A specific electrode arrangement for a burner already exists with which the flame of the burner is influenced by using electrical fields, whereby these electrical fields pass through only areas of the flame in which a stabilizing and pollutant-reducing action occurs. According to at least one embodiment of the invention, the electrodes used to this end simultaneously serve both as probes for detecting flame properties as well as active field electrodes for influencing the flame properties. The probe signals can react to the voltage applied in an inertia-free manner to the electrodes without the involvement of mechanical elements. According to the associated device equipped with a burner and associated electrodes and with a power supply unit, the power supply unit furnishes a voltage that varies over time, and at least one measuring transducer exists that detects the current generated in the flame by the voltage between both electrodes and provides feedback to the power supply unit after amplification.
