摘　　要：在确定交、直流混联输电系统可靠性模型的基础上,基于元件状态持续时间抽样的蒙特卡罗模拟法抽取系统状态,提出交、直流混联输电系统的负荷削减非线性规划模型,并运用现代内点算法进行求解。算例证明:相对于以往的线性规划模型和求解算法,在保证计算速度的情况下,该模型和算法能获得更精确可信的可靠性指标;通过改进的IEEE30系统进行模拟仿真,验证模型的正确性和算法的有效性。On the basis of building the reliability model of AC/DC hybrid transmission system and selection of system state by Monte Carlo simulation based on component state duration sampling, the paper proposes a nonlinear programming model of load shedding in AC/DC hybrid transmission system and the solution through modern interior point algorithm. The calculation sample proves that this model and algorithm, compared with former linear programming model and solution algorithm, can achieve more accurate and responsible reliability specification in the case of ensured calculation speed. By analog simulation of improved IEEE 30 system, correctness and effectiveness of the algorithm are verified.
