摘　　要： 本文首次论述了交直流并联输电系统可靠性评估的运算条件,并建立起Monte Carlo模拟的数学模型和有关算法。失负荷判据中既考虑了系统的有功、无功以及电流和电压约束,也考虑了换流器运行点的限制,同时还包含了交直流并联输电系统静态稳定特性的影响。本文针对经简化的长江三峡交直流并联输电系统进行了实际应用。结果表明,本文方法是可行的。 The operation conditions for reliability evaluation of HVAC / DC parallel systems are presented in this paper for the first time.A model based on Monte Carlo simulation and the relevent algoritems are also proposed .The criterion for loss of load takes into account the constraints for active and reactive power,current and voltage limitations ,the feasible region for the working states of converter stations as well as the effects of system stability.The application to the Three-Gorge HVAC/DC Project is also described in this paper with results showing that the methods of this paper are correct and applicable.
