Abstract—Today’s modern interconnected power system is highly complex in nature. In this, one of the most important requirements during the operation of the electric power system is the reliability and security. Power and frequency oscillation damping mechanism improve the reliability. Because of power system stabilizer (PSS) low speed response against of major fault such as three phase short c...

A static synchronous compensator (STATCOM) is generally used to regulate voltage and improve transient stability in transmission and distribution networks. This is achieved by controlling reactive power exchange between STATCOM and the grid. Unbalanced sags are the most common type of voltage sags in distribution networks. A static synchronous compensator (STATCOM) is generally used to maintain...

ABSTRAK Pertumbuhan ekonomi di indonesia berbanding lurus dengan permintaan energi listrik masyarakat yang terus meningkat. Dampaknya adalah sistem tenaga akan menimbulkan berbagai masalah dalam penyaluran listrik, seperti drop tegangan diluar batas diijinkan, dan rugi daya bertambah besar pada saluran. Salah satu solusi dapat dilaksankan untuk mengurangi saluran memperbaiki profil menggunakan ...

The paper presents a new effective method to damp subsynchronous resonance (SSR) – shaft torsional oscillations for large synchronous generators. This is achieved by using a dynamic power filter and static compensator (DFC) scheme. The proposed scheme with a switched series capacitor compensation and a modulated Tuned-Arm-Filter can be used to damp SSR oscillation modes using a novel Tri-loop E...

This paper compares four converter topologies for the implementation of flexible ac transmission system (FACTS) controllers: three multilevel topologies (multipoint clamped (MPC), chain, and nested cell) and the well-established multipulse topology. In keeping with the need to implement very-high-power inverters, switching frequency is restricted to line frequency. The study addresses device co...
