Abstract
The series voltage source converter(SVSC) is widely used in the power electronic equipment, such as series active power filter, dynamic voltage restorer, unified power flow controller and so on. However, while the SVSC is more vulnerable to the impact of fault current, its applications are increasing, bringing huge challenges to the safe operation of the grid. In recent years, the topology and control strategy of the series voltage source converter with fault current limiting(SVSC-FCL) are a research hotspot. In this paper, it suggests classifying SVSC-FCL based SVSC into two groups: the control scheme optimization group and the existing topology improvement group. The research challenges and perspectives of the SVSC-FCL are introduced in detail. This paper aims to illustrate current research progress on SVSC-FCL and enrich the available pool of the multi-functional power electronic equipment.
Highlights
With wide use of the nonlinear loads and introduction of numerous distribution generations(DGs), voltage disturbances present serious problems associated with the power quality[1,2]
To prevent the negative effects of voltage disturbances and fault currents and to improve the reliability of the network, various kinds of series compensators are installed in the power grid[7,8], including series active power filters(SeAPFs)[9], dynamic voltage restorers (DVRs)[10], static synchronous series compensators (SSSCs)[11], interline power flow controllers (IPFCs)[12], universal power flow controllers (UPFCs)[13], and unified power quality conditioners (UPQCs)[14]

Jiang et al.: A Review of Series Voltage Source Converter with Fault Current Limiting Function faults is too small compared to the normal operation periods of the power system Another problem is the in the limited use of FCLs, making them inefficient as a grid investment. The SVSC and the FCLs can improve the quality and the reliability of the power grid, installing two separate devices to suppress power quality problems and limit fault currents may not be a cost-effective solution. This paper reviews the literature on the series voltage source converter with fault current limiting (SVSC-FCL) function.
