葛洲坝电站HOMIS在线监测系统振摆传感器常见故障分析及处理

HOMIS在线监测系统已在葛洲坝电站运用多年,在及时为机组发现故障隐患,分析和掌握机组的运行特性,指导机组运行和检修维护,辅助进行各项性能试验,提高电厂数字化和网络化水平等方面发挥了很好的作用。但在线监测系统测量元件本身往往会出现故障或异常等现象,给机组状态的实时监测带来了一定的影响,尤其是机组的振动和摆度传感器,它们作为机组重要部件的监测元件,在机组实时安全、稳定运行过程中发挥着至关重要的作用。在这里着重对这些振动、摆传感器常见的故障进行分析和探讨,并对这些故障的处理进行总结研究,为这些振动、摆传感器在日常的运行和维护过程中提供一定的指导意义。

水电机组在线监测系统简析

水电站中对机组的在线监测,已经是中大型水电站中必备系统,该系统不仅能够实时监测机组的运行状态,提供机组检修的数据支持,还能对机组故障进行分析。本文通过机组在线监测经典配置,浅谈其在水电站中的使用。

Evaluation of Skills in Swing Technique in Classical Japanese Swordsmanship in laido Using Sensors

In this study, we analyzed the swing motions of more experienced practitioner and new practitioner of iaido players by using tri-axial acceleration sensor and gyro sensor. Iaido is a modern Japanese martial art/sport. In this way, the acceleration and gyro sensor measurement enabled detailed motion information at the installation points to be displayed in a short time, thus making it possible to easily extract the objective problems. Although it was not possible to confirm by the acceleration and angular velocity measurements the detailed motion of the entire body as obtained in the 2D motion analysis with a high-speed camera, it was confirmed that the acceleration and gyro sensor is an evaluation means that can be installed easily and can provide the exercise information in a short time as an objective index.
