【摘要】：风电机组超温报警故障是风电机组最常见的故障形式之一,国内许多风电场都发生过由于部件超温而迫使风电机组降负荷运行甚至停机的情况,给企业造成重大经济损失。由于风电机组系统比较复杂,造成超温故障的原因很多,运行过程中表现出的故障模式以及产生的影响也不尽相同,因此深入开展超温故障模式及其影响分析研究,对于整体提升风电机组设备的可用率和经济性具有重要的工程实际意义。本文以华电福新公司灌云风电场的50台海装H-93型2000kW双馈型风电机组为对象,开展风电机组齿轮箱和发电机超温故障模式、影响及危害度的分析研究,在此基础上提出了解决超温问题的技术方案,并进行了试验验证,取得显著效果。具体研究内容及解决的关键技术问题如下：(1)针对风电机组关键设备(齿轮箱、发电机和控制柜)频繁出现的超温故障,以灌云风场实际运行数据为依据,对超温故障的影响进行了系统的统计分析,探讨了超温故障对风电机组综合能效的影响,给出了灌云风场设备超温故障对整个风场可利用率和发电量的统计分析结果。(2)针对设备超温故障模式,结合灌云风场实际运行经验和数据,开展了深入细致故障模式、影响及重要度(FMECA)分析,形成了风电机组齿轮箱超温故障的FMECA分析表和故障危害性矩阵分析图,从而确定了齿轮箱超温故障危害性最严重的故障因素,为深入分析计算风电机组齿轮箱超温问题提供了依据。(3)根据风电机组过热故障的FMECA分析结果,结合海装H-93风电机组的实际运行经验和故障统计数据,提出并实施了超温故障和提升效能的整体优化方案,达到了整体优化效果。
[Abstract]:Overtemperature alarm fault of wind turbine is one of the most common fault forms of wind turbine. Many wind farms in China have forced wind turbine to run or even shut down due to overheating of components, which has caused great economic losses to enterprises.Due to the complexity of wind turbine system, there are many reasons for the overheating fault, and the fault mode and its influence are not the same during the operation, so the research on the overtemperature fault mode and its influence is carried out deeply.It is of great practical significance to improve the availability and economy of wind turbine equipment.In this paper, 50 sets of H-93 2000kW doubly fed wind turbine units installed in Huadian Fuxin Guanyun Wind Farm are taken as the object of this paper. The overtemperature failure modes of gearboxes and generators of wind turbines are analyzed and studied.On this basis, the technical scheme to solve the problem of overtemperature is put forward, and the experimental results are verified, and remarkable results are obtained.The specific research contents and key technical problems are as follows: 1) in view of the overtemperature faults frequently occurring in the key equipment (gearbox, generator and control cabinet) of wind turbine, the actual operation data of the wind field in the irrigation cloud are taken as the basis.The influence of overtemperature fault on the comprehensive energy efficiency of wind turbine is analyzed systematically, and the influence of overtemperature fault on the comprehensive energy efficiency of wind turbine is discussed.This paper gives the statistical analysis results of the overtemperature fault of the irrigation cloud wind field equipment to the utilization ratio and electricity generation of the whole wind field. (2) aiming at the overtemperature fault mode of the equipment, combined with the practical operation experience and data of the irrigation cloud wind field, the detailed fault mode is carried out.The FMECA analysis table and the fault hazard matrix analysis diagram of the overtemperature fault of the gearbox of the wind turbine are formed by analyzing the influence and importance of the gearbox, and the most serious fault factors of the gearbox overtemperature fault are determined.According to the FMECA analysis results of wind turbine overheating fault, combined with practical operation experience and fault statistics data of sea installed H-93 wind turbine, the paper provides a basis for further analysis and calculation of overheating problem of wind turbine gearbox.The overall optimization scheme of overtemperature fault and efficiency is put forward and implemented, and the overall optimization effect is achieved.
