讨论了基于冗余度分析的海上风电场内部电能收集系统和传输系统可靠性提高方法。定义了风电场低压/中压网络与高压传输系统的冗余度。在同时考虑可靠性和经济性的前提下,提出了系统进行风电场冗余设计的方法。采用大型海上风电场设计实例对所提方法进行了验证,得到了最优冗余设计结果。该方法对于提高具有复杂拓扑的大型海上风电场电能收集和传输系统的可靠性具有一定应用优势。

针对大变形非线性结构拓扑优化问题,提出了基于混合细胞自动机(HCA,Hybrid Ce.lularAutomata)多空间域连续体结构拓扑优化方法;采用密度法,建立了单元相对密度表示的材料弹-塑性模型;以单元相对密度和应变能作为细胞自动机(CA,Ce.lular Automata)的状态信息,利用CA局部控制规则,修改相对密度,迭代实现各设计空间域应变能均匀分布;设计了多空间域拓扑优化HCA算法,采取多个对象同时耦合优化迭代,各自收敛策略,解决了多空间域优化迭代算法收敛稳定性问题;最后,以汽车保险杆结构横梁和支撑等两个设计空间为例,施加大变形动态载荷作用,对提出的多空间结构优化算法进行了验证,优化后结构有效地降低了碰撞作用力峰值达54%,提高了结构安全性.
