| Abstract: |
| Based on the relation between reactive power and voltage in MIDC(Multi-Infeed Direct Current )system,the model and algorithm for assessing voltage stability at commutation buses in MIDC system are presented.The concept of voltage regulative factor coupling rate(K)is also presen-ted.With a dual-converter HVDC system,the effects of control mode,SCR and electric distance be-tween subsystems on VSF and K are analyzed.The measures that improve voltage stability at com-mutation buses in MIDC system are given. |
| Key words: multi-infeed direct current system,voltage stability,model,algorithm |
