This paper proposes a nonlinear control strategy of a Static Synchronous Compensator (STATCOM) for improving transient stability of multimachine power system. The large scale and the complexity of modern power system require the nonlinear control strategy of the STATCOM. The concept of Lyapunov energy function is applied to derive the nonlinear control strategy and the proposed control based on...

Today Transmission & Distribution network of power systems are very stressed due to growing demand of better quality of power at lower cost. As a result transmission networks are operating on high transmission levels. Transient stability, damping oscillations etc are the major operating problems that power engineers are confronting during transmitting power at high levels.Transient Stability in...

The Generalized Unified Power Flow Controller (GUPFC) is a Voltage Source Converter (VSC) based Flexible AC Transmission System (FACTS) controller for shunt and series compensation among the multiline transmission systems of a substation. The paper proposes a full model comprising of 60pulse Gate Turn-Off thyristor VSC that is constructed becomes the GUPFC in digital simulation system and inves...

The hybrid renewable energy harvesting and grid integration system has been proposed validated in this work. uses a Wind Energy Conversion System (WECS) Solar Photo Voltaic (SPVECS). WECS Permanent Magnet Synchronous Generator (PMSG) driven by wind turbine. variable frequency voltage output of PMSG is rectified Diode Bridge Rectifier (DBR) stepped up Super Lift Luo Converter (SLLC 1), finally, ...

Many distributed energy (DE) resources are near load centers and equipped with power electronics converters to interface with the grid, therefore it is feasible for DE to provide ancillary services such as voltage regulation, nonactive power compensation, and power factor correction. A synchronous condenser and a microturbine with an inverter interface are implemented in parallel in a distribut...

The effect of the static synchronous compensator (STATCOM) on distance protection a high-voltage transmission line is studied in this article. To carry out research stated topic paper, an experimental scheme was developed, equipment selected, operation settings 3 stages were calculated and quad characteristics built their basis. All listed above, as well further experiments, carried by real tim...

Power quality problems in electric systems are one of the important topics that occupy a wide area ​​interest to researchers and engineers. The increased use power electronics circuits has led improve efficiency performance equipment; on other hand, they withdraw non-sinusoidal current increase harmonics which causes decrease quality. Also, these electronic devices sensitive problems. However, ...
