This guide outlines the design of protection systems for Dynamic Reactive Power Compensators (DRPC). The guide covers protection schemes and philosophies, instrument transformers, relay protection, control system protection, and testing related to the DRPC application. Differences between conventional substation and DRPC protection is discussed, including protection schemes and functions. Recommendations are provided for 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, ground...

This guide outlines the design of protection systems for Dynamic Reactive Power Compensators (DRPC). DRPCs play an important role in enhancing reliability and stability of transmission systems. The control and protection systems in a dynamic reactive power compensators system (static var compensator (SVC), static synchronous compensator (STATCOM) and Hybrid STATCOM) are custom designed according to the topology used for a specific application. Protection systems are intended to make use of the maximum operational limits of the equipment. Modern protection systems are fully integrated with the development of communication protocols and multifunctional Intelli...

The purpose of this guide is to describe: * differences in protection from conventional substation equipment * current practices in protection for SVC, STATCOM and Hybrid STATCOM systems * recommended protective functions to increase reliability, security and dependability * testing of SVC, STATCOM and Hybrid STATCOM protection systems
