摘要:
目的 为解决大型火电机组空气预热器传统预防性维护手段的弊端,提出了一种基于数字孪生预测性维护的一般模式,并基于数字孪生技术,构建空气预热器数字孪生系统。 方法 所提系统包括回转式空气预热器物理实体、实时数据采集与分析模块、数字孪生模型构建模块、热力参数状态监测、转子热场视频与热变形可视化及积灰预测模块;实时采集温度参数状态和视频数据,通过温度场、视频图像、漏风计算等模块,实现热力参数的计算并进行积灰的预测。同时,以3D组态画面实时显示数据,利用软件算法不断优化热力参数计算及积灰预测的准确度,实现吹灰策略自动优化。 结果 所提方案实现了空气预热器热力计算过程的状态监测与动态控制,解决现有电站中回转式空气预热器积灰因素影响火电机组安全可靠运行的问题。 结论 通过实际机组的工程测试,所提方案有效提高了火电机组空气预热器运行维护的效率,验证了所提方法的可行性,为后期智慧电厂系统的开发提供技术支撑。
