摘要
根据江西电网的实际情况,提出2种分别适用于500kV线路和220kV及以下电压等级线路的移动式直流融冰装置设计方案。前者考虑融冰、直流输电等多种用途,以可关断元件绝缘栅双极晶体管(IGBT)构成的电压源型换流器(VSC)为基础,通过模块化设计,实现装置与半挂式平板拖车整体移动。后者以简单实用为前提,采用基于晶闸管的三相全控整流桥的主电路结构,整体装置通过集装箱吊装实现移动化。结合现场调试经验,提出了较为完整的直流融冰装置调试试验方法及其注意事项,为类似装置的工程应用提供了有益的参考。
According to the practical situation of Jiangxi Grid, two kinds of movable DC de-icer design which are respectively suitable for 500 kV and 220 kV or under transmission line are presented. The former may work as DC de-icer or as HVDC transmission, etc. Its main equipment is built based on the voltage source converter （VSC） with insulated gate bipolar transistor （IGBT）, which realizes removability with semi-mounted platform trailer by modular design. The main circuit structure of the latter one is used three, phase controlled thyristor bridges to meet practical requirement. The removability of whole system is implemented with container suspension. Combined with testing experience on site, an integrated commissioning method of DC de-icer and some key remarkable items are put forward. It may be an useful reference for testing similar equipments,
