SHI Hui, CHEN Hao, ZHANG Jinfan, et al. Application Prospect of New Dynamic Reactive Power Compensation in Hunan Power Grid[J]. 2020, 40(1): 16-19.DOI:
In view of the shortage of dynamic reactive power support in Hunan UHV power grid development
the technical route of adding dynamic reactive power compensation in Hunan Power Grid is discussed. Through the comparison and analysis of four kinds of technologies such as FC
condenser
SVC and SVG
and the practice and summary of similar projects in China
this paper focuses on the analysis and demonstration of the new DC and the new SVG schemes.The simulation results show that the SVG dynamic reactive power support effect is slightly inferior to that of the condenser
but it has unique advantages in the cooperative control of dynamic reactive power and short-circuit current.
