| Abstract: | The reliability of converter transformer greatly impacts on the reliability of whole HVDC power transmission system,so it is necessary to enhance reliability evaluation of converter transformer system(CTS).A method to determine the transition rate among states of CTS with 12-pulse wiring,namely the failure rate,repair rate and installation rate,is proposed,and based on equivalent component group model a Markov state space graph for converter transformer subsystem with 12-pulse wiring,in which the standby co... |
