风电机组CMS系统试验性能比对研究

Comparative Study on Test Performance of CMS System of Wind Turbine

风电机组状态监测系统(Condition Monitoring System,下文简称CMS)用于实时监测风电机组的状态和智能故障预警,以保障风电机组安全运行,防患于未然。本文在同一测试环境下针对不同CMS系统的加速度传感器和后处理软件开展试验性能比对测试和研究,结果表明:不同加速度传感器在时域和频域的表现一致;而不同CMS系统后处理软件在不同频段的时域结果存在偏差,对风电机组传动链的振动频谱分析有明显差异。研究结果可提供多维度的不同CMS系统数据可靠性和准确度的评价标准,进而更有效地利用CMS系统实现风电机组的振动监测和故障预警。

The Condition Monitoring System(CMS)of wind turbines is used to monitor the status of wind turbines in real time and intelligent fault warning to ensure the safe operation of wind turbines and prevent problems before they occur.In this paper,under the same test environment,the performance comparison test and research of the acceleration sensors and postprocessing software of different CMS systems are carried out.The results show that:the performance of different acceleration sensors in the time domain and the frequency domain is consistent.However,the time domain results of different CMS system post-processing software in different frequency bands are biased,and there are obvious differences in the vibration spectrum analysis of the wind turbine transmission chain.The research results can provide multi-dimensional evaluation standards for the reliability and accuracy of different CMS system data,and more effectively use the CMS system to realize the vibration monitoring and fault warning of wind turbines.
