This paper presents a comprehensive survey on the mitigation of power quality problems such as low power factor, shortage of reactive power, poor voltage, voltage and current harmonics due to sudden change in field excitation of synchronous alternator, sudden increased in load, sudden fault occur in the system are solved by FACTS controllers such as STATCOM, DSTATCOM, and DSTATCOM. This paper a...

Wind power is one of the optimistic sources of energy generation among all the renewable energy sources. Hence for exploiting wind energy sources it must be connected to electric grid. Wind power inculation into grid affects power quality because of its fluctuating nature. This paper recommends a control scheme based on instantaneous SRF (Synchronous Reference Frame) theory for compensating the...

Internal Liability of power system transmission lines influenced by the turbulences owing to catastrophic disasters. In order achieve Constant Voltage Stability at both ends lines, Static Synchronous Compensator (STATCOM) is imperative. source Converter mechanisms augment with switching frequency control methodologies are widely adopted regulate reactive power. By deliberating IEEE Standards, m...

Over the recent period of time, power quality problems have been marked as a buzzing issue with regards to promote delicate or miniature electronic devices where Voltage sag problem is most frequently occurring well detrimental problems. Thus, purpose this study assuage voltage using proposed Distribution Static Synchronous Compensator (D-STATCOM). Utility distribution networks, sensitive indus...

In this paper, a novel approach based on the Thévenin tracing is presented to modified conventional impedance-based out-of-step (OOS) protection. In conventional approach, the OOS detection is done by measuring positive sequence impedance. However, the measured impedance may be change due to different factors such as capacitor bank switching and reactive power compensators that it can cause the...

TCSC (Thyristor-Controlled Series Compensator) has been used in modern power systems to increase power transfer and system stability. Besides, due to its controllable feature, TCSC has been used to work as a solution to sub-synchronous resonance (SSR) problems. However, it is not clear so far whether TCSC’s inherent characteristic can avoid SSR and its effectiveness for SSR damping. In this pap...
