如何提高高原型山地风电场35kV集电线路可靠性的研究

How to Improve the Reliability of 35 kV Collecting Line of High Prototype Mountain Wind Farm

高原型场地在建造风电场过程中,按照周围的环境进行匹配,采用35 kV的集成电路,出现65次的跳闸。在雷电、冰雪特殊天气下35 kV的集成电路有45次跳闸。特殊环境下35 kV集成电路线路跳闸,对风电场的安全稳定会产生较大的风险和威胁,会直接影响风电场的综合经济效益水平。为了更好地改善特殊天气下的35 kV集成线路电路跳闸的原因,需要结合跳闸产生的原因进行分析,对其需要改造的技术方案和改造形式进行研究,分析如何提升35 kV集成电路的运行稳定性,对可能发生跳闸的因素进行判断,分析如何实现集成电路的可靠性操作。

In the construction of electric field in plateau type site,the 35 kV integrated circuit is used to match the surrounding environment,and 65 trips occur.In the special weather of thunder,snow and ice,the 35 kV IC has 45 trips.The trip of 35 kV integrated circuit line in special environment will bring great risk and threat to the safety and stability of wind farm,and directly affect the comprehensive economic benefit level of wind farm.In order to better improve the cause of 35 kV integrated circuit tripping in special weather,it is necessary to analyze the causes of tripping,study the technical scheme and transformation form,analyze how to improve the operation stability of 35 kV integrated circuit,judge the possible factors of tripping,and analyze how to realize the reliability operation of integrated circuit.
