混合双馈入直流系统中LCC-HVDC对VSC-HVDC稳态运行区域的影响
The Effect of LCC-HVDC on Stable Operating Area of VSC-HVDC in Dual-infeed Hybrid HVDC System
摘要
Abstract
The influence mechanism of line commutated converter based high voltage direct current (LCC-HVDC) sub-system to the operation characteristic of voltage source converter based high voltage direct current (VSC-HVDC) sub-system in hybrid dual-infeed HVDC system needs further study.Firstly,the mathematical models of hybrid dual-infeed HVDC system with different LCC-HVDC control modes were derived in this paper.Based on these models,the security and stability constraints of the VSC-HVDC sub-system in hybrid dual-infeed HVDC system were analyzed and summarized.Then,an approach to determine the stable operating area of the VSC-HVDC sub-system in hybrid dual-infeed HVDC system was presented.Based on this method,the impact of the different control mode of LCC-HVDC sub-system,the short circuit ratio (SCR) of AC system and the capacity rate between LCC-HVDC and VSC-HVDC on the stable operating area of VSC-HVDC sub-system were studied.Lastly,the validity of the proposed approach was proved by hybrid dual-infeed HVDC simulation model built in PSCAD/EMTDC.关键词
