Protection of the VSC-HVDC Systems by employing Saturated Iron-Core Superconductive Fault Current Limiter
Fault analysis, dc line to line fault,VSC HVDC,uperconductive fault current limiter.
The high-voltage direct-current transmission based on voltage source converter (VSC-HVDC) system point towards the development of the distributed generation,which gain more importance nowadays. But one of the challenge faced is that VSCs are vulnerable to dc short-circuit faults.The reason behind it is the huge discharge current of the dc-link capacitor. Therefore saturated iron-core superconductive fault limiter is used to limit this current which will offer superior technical performance in comparison with conventional methods. Due to this advantage and practical demand SISFCL has been applied on transmission lines. The working principle behind the SISFCL are discussed . The relationship between the inductance and dc gird current of the SI-SFCL is deduced.Thus Current limiter (SISFCL) is introduced to limit the fault current to a relatively low level is discussed.
