【摘要】：冰雪天气对输电线路的危害重大,轻则发生冰闪,重则造成倒塔(杆)、断线,甚至使电网瘫痪。研究切实可行的输电线路融冰及实施方案对于提高浙江电网抵御冰灾等自然灾害能力、保障电网安全稳定运行方面、建设坚强浙江电网等具有重要的现实意义。本文在阅读相关文献的基础上,提出了浙江金华500千伏直流融冰项目实施方案研究的整体思路,即在钻研基本理论,了解项目输电线路现状的前提下,分析实施此项目的技术风险,进而提出浙江金华500千伏直流融冰项目实施方案的设计。本文首先阐述了项目实施管理的基本理论以及输电线路覆冰和直流融冰技术的基本原理,为后续的研究提供理论基础。其次,分析了双龙变电站基本情况和项目方案的控制风险,提出了项目的整体方案,为之后该项目具体方案实施的制定打下基础。最后,结合个方面的相关理论和变电站的基本情况,本文从项目实施的整体概念、方案实施风险分析、施工组织和现场管理、施工流程安排、施工管理相关措施制定等几个方面介绍了该项目具体的实施方案。
[Abstract]:The ice and snow weather is harmful to the transmission line, the ice flashover occurs in the light, and the tower is broken in the heavy condition. Even make the power grid paralyzed. The study of practical transmission line ice melting and implementation plan to improve the Zhejiang power grid to resist ice disasters and other natural disasters, to ensure the safe and stable operation of the grid. Building a strong Zhejiang power grid and other important practical significance. On the basis of reading the relevant documents, this paper puts forward the overall idea of the implementation of the 500kV DC ice-melting project in Jinhua, Zhejiang Province, that is, on the premise of studying the basic theory and understanding the current situation of the project transmission line. Analyze the technical risks associated with the implementation of the project. And then put forward the implementation scheme design of Zhejiang Jinhua 500kV DC ice-melting project. Firstly, this paper describes the basic theory of project implementation management and the basic principle of transmission line icing and DC ice-melting technology. Secondly, the basic situation of Ssangyong substation and the control risk of the project scheme are analyzed, and the overall project scheme is put forward. Finally, combined with the relevant theory of the project and the basic situation of the substation, this paper from the project implementation of the overall concept, the implementation of the project risk analysis. Construction organization and site management, construction process arrangement, construction management related measures and other aspects of the specific implementation of the project are introduced.
