Use of Superconducting Devices Operating Together to Ensure the Dynamic Stability of Electric Power System

Abstract

Among the superconducting power devices developed to nowadays first of all should be mentioned superconducting magnetic energy storage (SMES) and superconducting fault current limiters (SFCL) since they have the best test results while operation in real electric power systems. This study is aimed to the development of superconducting magnetic systems of both these devices operating in power system together, what facilitates the solution of two tasks. The first one is to assure the dynamic stability of electric power network itself by the joint operation of SMES and SFCL. The second one is to provide an uninterrupted power supply together with the assurance of stable operation for power system with the synchronous load, e.g., for oil refineries, the main power consumers of which are parallel operating synchronous motors. Under fault event which disturbs the normal operation, we understand here the sudden short-circuit leading to the disconnection of the damaged power transmission line.
