Smart switching reactor application and performance analysis

Weakly connected generators which are normally existed in actual power systems will be greatly affected by a nearby transient disturbance. A Smart Switching Reactor (SSR) has been used to improve the transient stability of the impacted generators. Different simulation models have been developed to study the effects of the SSR on the power system. The result shows that the transient stability has been improved while the small signal stability cannot be improved significantly. An application with the SSR has been carried out and the result demonstrates the valuable effects on protecting the generator from tripping frequently.
