Modelling and Analysis of Upfc Connected Single Machine System with Pss Design Using Sliding Mode Control Technique

The unique capability of the Unified Power Flow Controller in multiple line compensation are integrated into a generalized power flow controller that is able to maintain prescribed and independently controllable, real power and reactive power flow within the line. We demonstrate the proposed technique on a single machine infinite bus system. In this paper, we propose UPFC with PSS design scheme based on multirate output feedback control technique. Using different plant rates including the former plant output information, sampling error at multiple sampling intervals is thought-about. As a result, management and stability performance can be improved.
