为了保证高压断路器传动机构在运动过程中机械强度的可靠性,可应用CAE仿真技术,在设计初期对高压断路器传动机构进行建模和仿真计算,然后根据各部件的计算结果,对强度薄弱部件的结构进行优化,进而提高传动机构的可靠性.以某高压开关断路器传动机构为研究对象,首先利用三维软件进行设计建模,然后根据传动机构动触头行程与拐臂转角之间的一一对应关系,应用CAE仿真软件ANSYS Workbench软件中的刚体动力学与瞬态动力学仿真模块,求解传动机构在运动过程中,各部件的最大应力随时间变化曲线.最后结合机械寿命试验,对ANSYS Workbench运动仿真计算结果的可靠性进行验证.结果表明,ANSYS Workbench运动仿真计算结果可为高压开关断路器传动机构设计提供依据.

考虑到低压微电网中多逆变器并联运行时功率合理分配和环流抑制的问题,提出了一种基于虚拟阻抗的多逆变器并联运行控制策略.由于逆变器的等效输出阻抗存在较大的差异,通过引入虚拟阻抗使得逆变器的系统输出阻抗呈可调节的感性,降低了线路电阻引起的功率耦合,并改善了各逆变器输出电压质量.在此基础上通过改进逆变器的功率下垂控制策略,实现了并联逆变器之间较高的功率分配精度和良好的动态响应能力,抑制了并联逆变器之间的环流.最后,在Matlab/Simulink环境下构建多逆变器并联系统模型,分析了多逆变器并联运行特性,仿真结果
