    摘要: A method for extracting bitumen and/or extra-heavy oil from an underground deposit is provided. The energy for producing the steam and for the electric heating is generated in situ, for which purpose part of the extracted bitumen and/or extra-heavy oil is burned in an industrial turbine with a downstream generator coupled to the turbine. The industrial turbine may be a gas turbine or a steam turbine. In particular the industrial turbine with downstream generator is assigned a waste heat recovery steam generator which serves for generating the steam and accordingly takes the form of a boiler. Through intermediate storage of the bitumen and/or ultra-heavy oil produced it is possible to implement a self-contained closed circuit which operates autonomously, independently of any external energy supply, using approx. 20% of the extracted bitumen and/or extra-heavy oil for the purposes of extraction.

    摘要: A method for the in situ extraction of bitumen or very heavy oil from oil sand deposits close to the surface, where thermal energy is introduced into the deposit to reduce the viscosity of the bitumen or very heavy oil is provided. Condensed water is used that is introduced into the deposit via an injection pipe and is horizontally conducted inside the pipe within the deposit such that the water can evaporate in situ and the heat can be applied to the deposit. An apparatus including an injection pipe, an extraction pipe, a converter and electrical conductors are also provided.

    摘要: In a protective circuit for a converter having a plurality of phases, for each phase current of the phases, a signal proportional to the respective phase current is applied to a transformer circuit that, below and in the area of a limiting frequency, functions as a low-pass filter with the limiting frequency, and above the limiting frequency, functions as a divider. The outputs of the transformer circuit are applied to a maximum generator for forming the absolute value maximum. This maximum is fed to a comparator in which the maximum is compared to a reference value.

    摘要: A method is for the pulse width modified control of switching elements in a frequency converter having N phases, in which for each phase the control pulses of the switching elements are derived from, in each case, one P-periodic control voltage. The P-periodic control voltages correspond to a superposition of sinusoidal control voltages of period P, that are shifted by 360/N degrees with respect to one another, by an N*P-periodic offset voltage that applies to all phases. The offset voltage is selected such that, at any time, exactly one of the P-periodic control voltages lies effectively on a modulating limit for the derivation of the switching pulses. Using this method, the excitation of resonances at the star point of a connected load may be clearly reduced.
