摘要：
Without considering the power voltage characteristics of the system components, the existing short circuit ratios cannot measure the critical voltage stability point of the hybrid infeed HVDC system accurately. To deal with this challenge, a new index called the hybrid infeed short circuit ratio (HISCR) is proposed in this paper to analysis the critical voltage stability point of this system. First of all, a hybrid infeed power voltage sensitivity factor (HIPVSF) is derived from the Jacobian matrix as the basis of the following theoretical analysis, and takes into account the power voltage characteristics of the components. Then, the HISCR is proposed based on the HIPVSF considering the impacts of the dynamic power voltage characteristics of the HVDC links and the synchronous condenser. Finally, multiple simulations are conducted in this paper to verify the validity of the proposed index by using the PSCAD/EMTDCTM and the MATLAB. © 2021, Power System Technology Press.
