基于状态信息的风电机组维护研究综述

Review of Wind Turbine Maintenance Based on Condition Monitoring Systems

随着风电行业逐渐步入风电后市场时期,风电机组运维逐渐成为风电行业关注的主要问题之一。相比常规能源、传统汽车、航空等行业,风电机组运维存在由低行业利润限制、随机因素影响以及庞大维修基数等因素带来的特殊问题。首先对影响风电机组状态维护的不确定因素及其常用的模型与建模方法进行梳理;然后,从维护决策量化分析的角度,对风电机组常用的维护分类及建模方法、维护决策模型及决策方法等进行归纳;最后,对风电机组维护决策中仍存在的主要问题和难点进行总结,并提出一种兼顾全寿命周期长期运维优化与考虑短期随机因素影响的风电机组运维决策研究思路与框架。

With the great expansion of wind power after market, operation and maintenance(O&M) of wind turbines has been a big concern in wind industry. Comparing with O&M in the traditional power generation, motor and aviation industries, there are some special problems of the O&M of wind turbines(WTs) which are introduced by limits of low profit, impacts of stochastic factors, large number of WTs and etc. In this paper, firstly, the uncertainties affecting the O&M of WTs and their modelling methods were summarized. Secondly, the classifications, modelling methods and decision-making strategies of WT maintenance were described and analyzed. Finally, some difficulties and problems of the O&M of WTs were described and a decision-making framework both considering the life-cycle O&M optimization and short-term random factors was proposed in this paper.
