Static Shunt Compensators play an important role in enhancing reliability and stability of the transmission system. The control and protection systems in Static Shunt Compensators (static var compensator (SVC), static synchronous compensator (STATCOM) and Hybrid STATCOM) systems are custom designed according to one of several topologies intended for specific applications. An extensive protection system is ultimately intended to make use of the maximum operational limits of the equipment. Increasingly, modern protection systems are fully integrated with the development of communication protocols and multifunctional Intelligent Electronic Devices (IED). This guide outlines the current practice of protection system design for Static Shunt Compensators. Though it includes a brief overview of conventional protection schemes, the main focus is on special protection schemes required for the application and protection functions integrated in the control system or IEDs. The special protection schemes include protecting substation buses, power transformers and associated branches such as Voltage Sourced Converters (VSC), Thyristor Switched Capacitors (TSC), Thyristor Switched Reactor (TSR), Thyristor Controlled Reactors (TCR), harmonic filter banks, MV grounding transformers and auxiliary transformers connected to the MV bus. The guide also discusses the protection functions integrated in the control systems to protect the Static Shunt Compensator and its main components such as power electronic valves and associated cooling systems. Finally, the guide discusses the interaction of protective functions with the power system when exposed to transients during system disturbances, severe harmonics and DC current.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
