| Abstract: |
| The reliability evaluation of HVDC(High Voltage Direct Current transmission) system has become more important. A new way to calculate the reliability indices of HVDC system using FTA(Fault Tree Analysis) theory is given. The system fault tree is constructed based on the principle of HVDC and the reasons leading to system failure. It considers all system failure events and the spare components in station,and is an effective method. This project is supported by National Natural Science Fund of China(50337010). |
