Sharing Solutions for Common O&M Challenges at Hydro Projects

Hydro project owners 和 operators throughout the U.S. 遇到各种与操作和维护相关的挑战、问题和任务. Proper implementation of 操作 和 维护 (O&M)活动是水电站业主的主要关注点,通常消耗项目总预算的很大一部分.

虽然其中一些挑战是独特的,因为项目的地理位置和规模, others are much more commonplace.

根据最近的对话和发布的内容,五个常见的例子 干净的水流 Conference 和 Tradeshow 是:

在这篇文章中, we offer examples of solutions being applied to resolve these commonplace challenges.

Knowledge transfer from existing employees, many of whom are retiring, to new hires

这种知识转移是工程专业人员和行业员工都需要的,不仅是在水电项目中,而且在为水电项目提供服务和产品的公司中也是如此.

和, while the need is very real, 公司和组织面临着平衡这种知识转移和劳动力发展的需求,以及最小化劳动力预算增加的短期目标.

To address the knowledge transfer challenge, several utilities are developing internal mentoring programs, which pair senior engineers at the company with newly hired employees. 其他人则与当地的社区学院和大学合作,提供实习机会, with the idea of grooming the interns to become full-time employees.

许多资产所有者和服务/产品供应商使用国家水电协会的 Operational Excellence database as a workforce development resource. 数据库, available exclusively to employees of beat365官方app下载 member organizations, is a repository of reports describing safety, 操作, 维护, 和环境绩效——在美国各地实际的水电项目中发生的事件.S. 每个事件报告(已修订的敏感信息)提供所发生事件的详细信息, the lessons learned, 和 recommended changes to implement to prevent the same problem from re-occurring. 事件报告提供了现成的事件,以便在每天的“后门”安全会议或每周的员工会议上审查和讨论.

Processing 和 monitoring data from digital sensors

With the advent of digitalization, many asset owners are being inundated with data. 为了管理所有这些数据,一种解决方案是建立一个集中的监视和诊断(M&D) center that is staffed 24 hours per day, seven days per week. 这些中心的工作人员在机器学习软件的帮助下监测来自水力发电机组的数据和趋势,该软件分析数据的模式和潜在的异常情况. By reviewing data in real time, 工程师可以发现异常情况,并在设备成为主要问题之前进行干预. This approach is resulting in less damage to equipment 和 thus reduced unit downtime.

Other asset owners use a third party to perform this service offsite. Data is gathered 和 provided to the offsite support organization, 分析数据并通知工厂操作员任何可能需要注意的异常情况.

Ensuring Crane Capabilities

Powerhouse cranes play a vital role in plant rehabilitation / modernization. In many powerhouses, these cranes are not frequently used. 因此, 操作问题可能只有在起重机实际投入使用时才会暴露出来……通常在一个紧凑的修复或现代化时间表下.

一个及时发现和解决起重机操作问题的解决方案是制定一个标准程序,在任何重大项目前一日历年对厂房起重机进行评估. 以这种方式, 资产所有者可以识别潜在的问题并执行必要的纠正工作.

Noise abatement in the powerhouse

减少或消除水电设施某些区域的高噪声水平是许多水电项目业主和运营商讨论的“首要”话题. 美国职业安全与健康管理局(OSHA)规定,暴露8小时的噪音上限为90 a加权分贝(dBA), including a 5 decibels (dB) exchange rate. 对于85 dBA及以上的噪音水平,雇主必须有听力保护计划.

Turbine wheel pits, common mechanical equipment rooms, 通风管画廊通常是水电设施内的位置,在那里可以发现噪音水平高于85 dBA水平.

In 2015, the Bureau of Reclamation 和 the U.S. 陆军工程兵团对水电站的噪音进行了研究,并发表了报告, 水力发电厂降噪工程控制,最终报告ST-2014-6433-01, provides several possible solutions to abate noise in hydropower facilities. Solutions include engineered enclosures for noisy equipment, installation of acoustical absorption panels 和 clear plastic strip curtains, 和, 当然, purchase of quieter equipment. Although the report is several years old, 在寻找噪音消除解决方案时,它仍然被认为是一个很好的公共可用的“首选”参考.

Managing impacts of zebra mussels

入侵的斑马贻贝(多形德赖森贻贝)正在影响美国各地的许多水电厂.S. The microscopic larvae, called veligers, 在河水中移动一段时间,然后附着在任何他们能找到的坚硬表面上. The veligers clog cooling water strainers, generator 和 thrust bearing oil coolers, 和 the plant’s piping. Consequently, generating unit outages are required to perform periodic cleaning. The larger mussels also attach to the unit’s trashracks.

To control the invasion of these mussels, the U.S. Army Corps of Engineers, at its 132-MW Gavins Point Dam on the boarder of Nebraska 和 South Dakota, 是否安装了紫外线照射系统,在进入工厂的冷却水系统之前将处于幼虫阶段的斑马贻贝杀死.

部队正在试验的其他控制措施包括在垃圾架和内部管道表面涂上防粘涂层或更换材料.

Why Sharing of Solutions Matters

项目业主和运营者一致认为,分享他们遇到的问题,并寻求其他业主的意见,这是至关重要的,因为他们寻求以安全和经济的方式保持其发电机组的可靠性.
