| Abstract: | The 50 Hz and 100 Hz protection setting principles are introduced. The actions of 50 Hz and 100 Hz protections during Gaoling back-to-back HVDC system commission test are studied. The digital simulation software PSCAD/EMTDC is applied to study the action and cooperation of 50Hz and 100Hz protections in Gaoling back-to-back HVDC system, by which the correctness of above-mentioned protections are verified. The analytical results are instructional and helpful for the operation and maintenance of HVDC station. |
