Reliability evaluation for main electrical scheme of simultaneous AC-DC power transmission

H. Rahman and B. H. Khan have given a new model for simultaneous AC-DC power transmission through a transmission line. This paper model formation to evaluate the reliability of main electrical scheme. Use advanced four state component model, redefined abnormal state and maintainable state, combined maintenance state based on condition of component and schedule maintenance state to maintenance state on the basis of taking account of the condition-based maintenance and then confirmed the conversion relationship and the parameter to each state. The main electrical scheme is simplified on the basis of function and gets more simple net. For DC station, it simplified with the method of combining components and dividing subzone. Apply advanced four state component model to make certain reliability parameters of each part and get reliability parameters of main electric scheme through Markov model.
