Short Circuit Ratio of Multi-HVDC System of Rectifier Station Near the Inverter Station
Multi-infeed short circuit ratio (MSCR) is an important reference index in the study of multi-infeed HVDC power system,however,previous studies only consider the sending end or receiving end.For multi-HVDC system of rectifier station near the inverter station,the traditional MSCR has been unable to correctly describe its running characteristics.Based on the original research,this paper studies the MSCR of multi-HVDC system of rectifier station near the inverter station,analyzes the influence of electrical distance,and generalizes the variation rule of its MSCR.Finally,based on CIGRE model,a 2-different end DC power transmission model is built.The simulation analysis has verified its validity.
