Abstract
This paper deals with the new frequency controller of the HVDC scheme linking Haenam to Cheju Island. The primary aim of the study is to develop and evaluate a new frequency controller after the removing of the present synchronous compensators. The simulation methods are the mix of PSCAD/EMTDC and PSS/E, the main system studies are done for the transient state analysis using PSCAD/EMTDC. The study cases are completed involving 3 phase, single phase trip and load tripping events and study plots presented. In conclusion, the new frequency measurement from the AC network gives effective frequency control and dynamic performance.
