| Abstract | ||
| Recently, power system engineers have faced numerous difficulties in adding new power stations and transmission lines to face the continuous need of electrical power. In the future, superconducting generators (SCGs) are expected to be the most suitable solution for the previous problem. This paper presents the design and implementation of Posicast Input Command Shaping(PICS) which is combined with phase advance controller in the governor control loop for a SCG against infinite bus system. This is to improve the system performance, enhance its stability and reduce the exhibiting oscillations. To achieve a high degree of accuracy, a detailed non-linear system model is considered including SCG, governor, turbine, controllers, transmission lines and non-linear constrains. The performance of the SCG equipped with the phase advance controller has been studied and the results were obtained in a comparative form with others obtained when PICS is used under different faults (3-phase short circuit for 120ms and 10% step increase in the mechanical input) and over a wide range of operating conditions. | ||
