摘要
直流融冰装置是目前电网抗冰的主要利器,在冬季应对低温凝冻天气对主网的侵袭中发挥巨大作用。总体来说,基于各种器件研发的各类装置能够对不同长度、不同导线型号线路进行直流融冰,装置的适应性较好,但各类型装置有不同的受限条件。本文介绍了直流融冰技术以及基于各种类型功率器件研发的各类型装置,对比了各种类型直流融冰装置技术特点和经济性,对装置在实际运行中存在的问题进行分析总结,并展望未来直流融冰技术发展的几个方向:基于新器件、新拓扑研发新型直流融冰装置,同时结合直流输电相关技术的发展,拓展直流融冰装置的应用,除冬季抗冰外,其余时间可兼具其他功能应用,提升装置资产利用率和解决装置长期不用带来的缺陷率增加、运行可靠性降低问题。
DC deicer is the main weapon of anti ice in power grid at present.It plays an important role in dealing with the attack of low temperature and freezing weather on the main network in winter. Generally speaking, all kinds of devices based on various devices can be used for DC ice melting of lines with different lengths and different types of wires. The adaptability of devices is good, but each type of device has different limited conditions. This paper introduces the DC deicing technology and various types of devices based on various types of power devices, compares the technical characteristics and economy of various types of DC deicing devices, analyzes and summarizes the problems existing in the actual operation of the device, and looks forward to several directions for the development of DC deicing technology in the future: Based on new devices and new topology, new DC deicing device is developed. Combined with the development of DC transmission technology, the application of DC deicing device is expanded. In addition to anti icing in winter, other functions can be applied in the rest of the time to improve the utilization rate of device assets and solve the problems of increasing defect rate and reducing operation reliability caused by long-term use of the device.
