Abstract
The discovery of the high-temperature superconductivity (HTS) phenomenon has created the possibility of introducing electrical devices with unique characteristics. The second generation HTS wire based on yttrium ceramics has a layered structure, in which the superconducting layer occupies a small fraction. In the load mode, the HTS wire has zero resistance, and when overcurrent occurs, the superconducting layer goes into the normal state, in which it has a high resistance. The current flowing through the wire is forced into non-superconducting layers (mainly the copper layer), which in turn can significantly limit the current due to the relatively small cross-section. On this basis, high-temperature superconducting fault current-limiting devices (FCL) of resistive type have been created. In Russia and around the world, the development of HTS FCL is actively underway, one of the largest projects has been implemented in Moscow. It is of interest to study the issue of the influence of HTS FCL on the stability of power transmission when installing the FCL near the generator. The article examines the influence of HTS FCL on stability using the example of the simplest power transmission generator - infinite power bus when installing FCL at characteristic power transmission points. A criterion for the preferred value of active resistance is proposed based on the condition of the minimum deviation of the rotor angle at the initial moment of a short circuit. Simulation modeling was carried out in the Matlab/Simulink software and computing system. The positive effect of HTS FCL on the stability of power transmission in the event of short circuits is shown. The need to solve optimization problems for selecting the optimal active resistance of the HTS FCL is noted, and the vector for further research on the topic under consideration is determined.
