Abstract

In this study, a static synchronous series compensator (SSSC) is used to investigate the effect of this device in controlling active and reactive power flow in transmission line. The SSSC is series injected voltage source controller, which leads or lags line current by 90°. In this paper, series compensation provided by an SSSC is considered.  A systematic procedure for modeling, simulation and optimally tuning the parameters of a SSSC controller in a multi-machine system, for power system stability enhancement is presented. The problem of SSSC controller is formulated as an optimization problem and Real Coded Genetic Algorithm (RCGA) is investigated to search for the optimal SSSC controller parameters. The results obtained from simulations validate the effectiveness of proposed modeling and tuning approach for power system stability improvement.

Keywords

Abstract

Simple, sensitive, and specific spectrophotometric methods were developed and validated for quantitation of Metoprolol succinate and Hydrochlorthiazide in tablet dosage form. A new analytical method was developed based on the simultaneous estimation of drugs in a binary mixture without previous separation. In simultaneous equation method, Metoprolol succinate and Hydrochlorthiazide were determined by using their absorptivity values at wavelength maxima, viz., 222 nm and 272 nm. The standard deviation value for the different validation parameters was found to be between 0.094 and 1.01 for simultaneous equation method. This method is simple, accurate, rapid, and they require no preliminary separation and can therefore be used for routine analysis of both drugs in quality control laboratories.
