Abstract

The short-circuit current level is an important index to evaluate power system strength. With increasing transmission capacity between different zonal power systems, the receiving-end grid is gradually confronting with the network structure with multi-infeed DC transmission.The status quo requires better control on short-circuit capacity so as to assure the safe and stable operation of the DC-AC hybrid power system. In this paper, the interaction among short-circuit current, the transmission capacity of DC tie-line, and the voltage support is studied. Moreover, on the basis of the average difference between short circuit ratio(SCR) and multi-infeed short circuit ratio(MISCR), a novel method for short-circuit current control is proposed. Synthesized with the latest ultra-high voltage network planning in Eastern China Grid, the specification for short-circuit control of converter station is also put forward, which can address the constrains of multiple DC intercon- nections in Eastern China Grid. The research work presented in this paper can afford the guidance information to future planning in terms of the location decision for converter stations in the receiving-end system with multiple DC interconnections.
