Abstract
One of the most important principles in power networks is system stability. For maximum use of investments in generation, present day systems work at their highest capacity. In other term, they are always at oscillating state and this reduces power system stability drastically. An ordinary generator has some flaws such as small output power density and low efficiency especially upon high powers; however, superconductor generator has higher efficiency than ordinary generator, and similarly, has greater stability upon occurrence of oscillations in power networks. From other side, use of fault current superconductor limiter for rapid removal of fault and ameliorating the transient stability also is effective for generator protection upon fault occurrence. Given above questions, the necessity of study and offering an approach regarding transient stability amelioration, modification of oscillations as well as protecting generators upon fault occurrence seems to be necessary. Here, by modeling an ordinary synchronous generator with infinite bus and comparing it with equal conditions upon fault occurrence with a superconductor generator at the presence of fault current superconductor limiter, we examine the rotor kinetic energy oscillations upon fault occurrence using MATLAB software.
