BENEFITS OF VSC BASED TRANSMISSION SYSTEM

Voltage Source Converter (VSC) technology has been selected as the basis for several recent projects due to its controllability, compact modular design, ease of system interface and low environmental impact. Following are few factors which increase use of Voltage Source Converter in transmission system.

1. Independent control of reactive and active power.
2. Reactive control independent of other terminal(s).
3. Simpler interface with ac system.
4. Compact filters.
5. Provides continuous ac voltage regulation.
6. No minimum power restriction.
7. Operation in extremely weak systems.
8. No commutation failures.
9. No restriction on multiple in feeds.
10. No polarity reversal needed to reverse power. 
11. Black-start capability.
12. Variable frequency.
13. HVDC Light cable - economic extruded polymer.
