随着特高压交直流工程大规模建设和交直流耦合程度的加深,多直流馈入受端电网主变充电对直流输电及受端电网运行具有一定影响。根据规划2017年淮沪特高压交流南半环重要枢纽苏州站将投运,为了研究特高压交流苏州站启动调试期间充电对锦苏直流运行的影响,在RTDS中搭建了锦苏直流和淮沪特高压交流及周边等值交流电网,采用与锦苏直流输电工程在控制保护功能和故障下的暂态响应等方面特性一致的特高压直流控保真型装置与RTDS构成闭环仿真平台,对锦苏直流近区空充主变以及特高压交流主变后锦苏直流运行情况进行了仿真分析。结果表明 ...

为提高微电网故障恢复能力,文中提出了一种构网型储能变流器支撑微电网黑启动控制策略。首先,开展了微电网黑启动过程电压支撑和变压器励磁涌流产生的工作机理分析。在此基础上,采用虚拟同步机(virtual synchronous generator,VSG)技术控制构网型储能变流器作为黑启动微源,为孤岛微电网提供电压支撑,并将构网型储能变流器当作主电源而跟网型储能变流器当作从电源进行协同配合;其次,提出一种构网型储能变流器输出电压建立的柔性启动策略,以减小配电变压器的励磁涌流。最后,在MATLAB ...
