混合多馈入直流输电系统相互作用关系的定量评估方法
A Quantitative Evaluation Method on Interaction Analysis of Hybrid Multi-infeed HVDC System
摘要
Abstract
Apparent increase in short circuit ratio (AISCR) is an index to quantitatively evaluate the impact of voltage source converter based high voltage direct current (VSC-HVDC) on line commutated converter based high voltage direct current (LCC-HVDC) in hybrid mutli-infeed HVDC system. Based on the AISCR index, the impact of VSC-HVDC on LCC-HVDC was further studied considering different power flow direction of VSC-HVDC link. Then, the transient performances of LCC-HVDC, such as transient over-voltage, commutation failure immunity and fault recovery performances, were investigated in PSCAD/EMTDC software, when VSC operates as rectifier or inverter. Considering the electric distance between VSC-HVDC and LCC-HVDC, the trend of AISCR was calculated with varying distance. Finally, the coupling effects of AC system and VSC-HVDC on AISCR of LCC-HVDC were decoupled, and the AISCR impacted by VSC-HVDC only, without the impact of AC system, was obtained. The conclusions got could provide valuable theoretical guide for capacity and feed-in location selection of VSC-HVDC in hybrid multi-infeed HVDC system.关键词
