The USSC is an active filter (AF) and it compensates the reactive power, harmonics in both the voltage and current caused by loads. The USSC makes use of two back to back connected IGBT based voltage source inverters (VSIs) with a common DC bus. One inverter is connected in series and the other one is placed in shunt with the load. The shunt inverter works as a current source and it compensates the current harmonics. The series inverter works as a voltage source and it helps in compensating the voltage harmonics. Previous works presented a control strategy for shunt active filter with PI control. Then, this control strategy was extended to develop the two controllers for shunt and series active filters. The simulation results of these control strategies are listed for comparison and verification of results","PeriodicalId":191301,"journal":{"name":"2006 IEEE Power India Conference","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124721114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed AC-DC converter is based on a star connected autotransformer, designed for producing 15-phase shifted AC voltages for effective harmonic reduction. The proposed 30-pulse AC-DC converter is suitable for retrofit applications, where, presently a six-pulse diode bridge rectifier is being used. The resulting supply current is near sinusoidal in shape with low total harmonic distortion (THD) of supply current and a nearly unity power factor. The effect of load variation on various power quality indices is also presented.

The problem is posed as an initial value problem. The autonomous system considered is a function of n state variables. The period is unknown for autonomous systems. The total number of unknowns to be determined at each step is n+1, i.e., n state variables plus the time period T. Since autonomous systems admit an infinite number of periodic solutions each one differing from the others by a translation in time, to have a unique solution, an appropriate value for one of this n+1 variables is assumed. The recasted system of n nonlinear algebraic equations in n unknowns is solved iteratively using Newton-Raphson method. This will give one periodic solution and its period. To have a continuum of solutions, a locally parameterised continuation procedure is adopted. Stability of periodic solutions along the continuous branch of solutions is determined by computing characteristic multipliers. The effectiveness of the algorithm is demonstrated by conducting bifurcation analysis on a three-node power system","PeriodicalId":191301,"journal":{"name":"2006 IEEE Power India Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131117429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
