This paper presents harmonics elimination in H-bridge Multi-Level Inverter. The basic concept of this reduction is to eliminate harmonics in different level with an appropriate choice of switching angles. This paper employs Homotopy algorithm to solve the transcendental equations for finding the switching angles. This method solves the nonlinear transcendental equations. In order achieve a wide range of modulation indices with minimize total harmonics distortion (THD) in particularly third, five and seven level. It is much simpler formulation without complex analytical calculations for any number of voltage levels. It has several informative simulation results verify the validity and effectiveness of the proposed algorithm using MATLAB/SIMULINK.Keywords

In this paper, the advancement in small signal stability via the optimal placement of Static Synchronous Compensator (STATCOM) and its performance is considered. The Eigen values are employed to analyze the stability of the WSCC system and the analysis has been done by PSAT software. It has been studied through light, medium, heavy, heavy one loading conditions unlike the existing system. At heavy one loading condition, the stability of the system collapses and the system has positive Eigen values. The system with STATCOM has the ability to work with stability though it undergoes heavy one loading conditions compared to the system without STATCOM and the positive Eigen values in the system is nil. The outcome of the proposed approach shows that STATCOM enhances the small signal stability excellently in the power system network.Keywords
