Impact of static synchronous compensator on flux‐based synchronous generator loss of excitation protection

Abstract: In order to increase the power transfer and providing the optimum utilisation of the power system capability, application of flexible alternating current transmission system (FACTS) devices technology, such as static synchronous compensator (STATCOM), has been attracted, in recent years. However, the STATCOM changes the voltage and current of the power system that disturb the operation of the impedance-based synchronous generator loss of excitation (LOE) protection. Then, this study proposes a new flux-based L… Show more

“…There are several techniques based on magnetic flux variation in the air gap that have been presented ( [9] and [10]) but those techniques have been criticized. This is because in order to measure the machine flux, search sensors coil should be utilized but there is a natural reluctance to install it because it may lead to machine damage [8].…”

“…In more recent studies, methods of improving the performance of relays in the presence of FACTS devices have been developed. The study conducted in Yaghobi is an attempt to present an LOE protection method based on flux in the presence of STATCOM. It is also shown in Ghorbani et al that by transmitting the voltage and current information of the two ends of the GIPFC line, the GIPFC effect can be reduced in LOE protection.…”

“…Static synchronous compensator (STATCOM) is one of the important members of FACTS family that is vastly applied on long transmission lines in modern power systems. It plays various roles in the operation and control of power systems, such as scheduling power flow, decreasing unsymmetrical components, reducing net loss, providing voltage support, limiting short‐circuit currents, mitigating subsynchronous resonance, damping the power oscillation, and enhancing the transient stability . A power network with a STATCOM is a complex system with so many issues to be addressed.…”
