The design of digital delay line and low voltage-monitoring system for Kicker power supply

踢轨磁铁（Kicker）电源系统是兰州重离子加速器冷却储存环（HIRFL-CSR）注入引出系统中实现快引出的一个关键元件，主要功能是为踢轨磁铁提供快脉冲励磁电流以产生所需要的快脉冲磁场。踢轨磁铁（Kicker）电源系统各触发脉冲是否同步关系到束流能否顺利注入引出以及有好的束流品质。基于此，本文介绍了基于CPLD-EPM1270T144的数字延迟线系统，以满足HIRFL-CSR踢轨磁铁（Kicker）电源对触发脉冲进行适当延迟的要求；分析介绍了数字延迟线系统结构、工作原理、PCB制版及系统调试 ...

构网型储能变流器支撑微电网柔性黑启动的控制策略研究

Gaoya dianqi
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 ...

The design of Kicker power supply digital delay line and low voltage detection system

踢轨磁铁（Kicker）电源系统是HIRFL-CSR注入引出系统中实现快引出的一个关键元件，主要功能是为踢轨磁铁提供快脉冲励磁电流以产生所需要的快脉冲磁场。Kicker电源提供的是高电压大电流的快脉冲，电流脉冲上升沿和下降沿为150ns,脉冲宽度为650ns,其脉冲峰值电流为2700A，工作周期为10s-17s。因此及时监控Kicker电源闸流管的工作状况以及电流脉冲波形特性至关重要。本文针对踢轨磁铁（Kicker）电源的需要，进行了Kicker电源监测系统的设计，主要针对闸流管误漏导通检测 ...
