采用常规直流配置动态无功补偿或柔性直流对受端广东电网稳定性影响的对比分析
Comparison on Influence of LCC-HVDC+Dynamic Reactive Power Compensation or VSC-HVDC at Inverter Side on Stability of Guangdong Power Grid
摘要
Abstract
Aiming at Wudongde multi-terminal UHVDC project, this paper studies the influence of line commutated converter HVDC ( LCC-HVDC) configured with dynamic reactive power compensation scheme or voltage source converter HVDC ( VSC-HVDC ) scheme on the stability of inverter side of Guangdong Power Grid.Firstly, STATCOM is selected as the dynamic reactive power com-pensation devices after comparing technical performance, voltage stability and real performance.Secondly, the stability of receiving-end grid is analyzed when LCC, LCC+dynamic reactive power compensation devices and VSC are used seperately when the receiving-end is at eastern Guangdong and at western Guangdong.Research results show that STATCOM should be put into operation in different levels for LCC scheme if the N-1 constraints are satisfied and the ability of withstanding severe AC system faults increases to the level of VSC scheme.关键词
