摘要
针对汽轮机安全监视(TSI)系统在高温高压及频繁调峰工况下故障率高、非计划停机频发的问题,提出一套可靠的提升策略,创新性制订三级量化检修标准,并结合激光对中与“五步法”安装工艺,使探头合格率提升至98.7%;开发CNN-LSTM智能诊断系统,能实现故障早期识别与动态阈值提前预警,使修复时间减少90%;构建的数字孪生平台,能使LVDT差胀监测误差降至±3μm。研究成果为TSI系统可靠性优化提供了有效范式。
To address the problems of the high fault rate and frequent unplanned shutdowns of the TSI system of the turbine in the working conditions of high-temperature,high-pressure and frequent peak-shaving,a set of strategies for reliability improvement is proposed.Formulating a three-level quantitative maintenance standard in an innovative way as well as combining laser alignment with the“five-step”installation technique can increase the qualification rate of the probe to 98.7%.In addition,it can achieve early fault identification and dynamic threshold early warning,reducing the repair time by 90%.The constructed digital twin platform can reduce the error of the LVDT differential expansion monitoring to±3μm.The research results provide an effective normal form for the reliability optimization of the TSI system.
