构网型储能PCS变流器控制策略及发展趋势综述

Gaoya dianqi
作为未来电力系统的重要供能来源，以风光为主的新能源发电给电力系统带来了波动性和间歇性等诸多困扰，储能装置具有平抑新能源出力波动，维持电网稳定的功能，其中，储能功率转换系统（PCS）即储能变流器，作为储能设备的并网接口，其控制特性显著影响储能单元的并网特性。传统跟网型控制变流器存在功率调节能力低、缺乏电网支撑能力等问题，研究中陆续提出了构网型（grid-forming，GFM）变流器的控制模式，储能单元结合构网型控制策略可有效改善电网侧的动态性能和稳定性。文中阐述了构网型储能变流器的结构和特点 ...

基于改进遗传算法的高压隔离开关主开关机构优化设计

Gaoya dianqi
水平伸缩式高压隔离开关因其占地面积小、产生断口明显，在高压电网中应用广泛。但其主开关机构在分合闸过程中产生较大的重力矩变化，除需配置合适的平衡弹簧，还需对结构进行优化设计，以减小机构所需驱动力矩。文中以550 kV交流高压隔离开关为对象，对主开关机构进行力学分析，并基于改进遗传算法对主开关机构进行优化设计、建立动力学仿真模型并进行验证，确定高压隔离开关工作时所需电机驱动力矩的最小值。结果表明，改进遗传算法相比传统方案所需最大电机驱动力矩减小22%，驱动力矩变化量减小43 ...
