Description
技术领域
本说明一般涉及机械/电装置的操作、监控和诊断,更具体而言,涉及自动向操作员提醒重型燃气涡轮机的异常行为的***和方法。
背景技术
监控机械健康并向操作员警告异常机械状况是操作一个或者多个机器的重要部分。具体而言,监控选择的辅助***过程参数对于燃气涡轮机辅助***的健康监控是重要的。当前没有用于大多数辅助***过程参数的在线估计的已知的监控***,并且仅监控测量的参数。不通过将测量值与期望值比较,定义警报阈值的动态基线和物理见解是未知的。没有该计算,仅基于与预设值的恒定偏差的静态阈值是可用的。此外,没有辅助***过程参数的估计,阻碍了故障排除。例如,可以对偏差的源是否在期望值与测量值之间进行确定。此外,快速改变的可操作状况或者非常慢改变的可操作状况可能使得操作员难以识别异常状况或者可以做出什么可操作改变来减轻异常状况。
至少预定义了一些已知的仅监控测量值并使用对于相同类型的机器静态阈值的历史数据的辅助***监控***,使得如果测量值超过预定义的阈值则发出警报。需要很多尝试来定义并细化这些没有考虑到机器运行或者负载状况的阈值。该***容易发出太多虚假警报,并且实际故障一般检测得太晚。此外,在该***中仅提供有限的故障排除信息或者不提供故障排除信息。
发明内容
在一个实施例中是一种计算机实现的方法,用于监控并诊断燃气涡轮机的辅助***中的异常,所述方法使用耦接至用户界面和存储器设备的计算机设备实现,所述方法包括:将多个规则集存储在所述存储器设备中,所述规则集与所述燃气涡轮机的所述辅助***有关,所述规则集包含表达为实时数据输出相对于实时数据输入的关系表达式的至少一个规则,所述关系表达式特定于与所述燃气涡轮机的所述辅助***关联的参数;从与所述燃气涡轮机关联的状况监控***接收实时和历史数据输入,所述数据输入涉及与所述燃气涡轮机的所述辅助***关联的过程参数;以及使用接收的输入,对与所述燃气涡轮机的所述辅助***关联的参数的至少一些估计值。
在另一个实施例中是一种用于燃气涡轮机的辅助***的监控和诊断***,所述燃气涡轮机包括流连通的轴流压缩机和低压力涡轮机,所述***包括涉及所述辅助***的多个规则集,所述规则集各包含实时数据输出相对于实时数据输入的关系表达式,所述关系表达式特定于有关所述辅助***的相应的过程参数的输入。
在又一个实施例中是一个或更多的非临时性计算机可读存储介质,具有实施于其上的计算机可执行指令,其中,当至少由一个处理器执行时,计算机可执行指令使处理器接收燃气涡轮机的辅助***过程参数的测量值,接收测量值和与燃气涡轮机关联的参数的推断值,估计接收的测量值的相应的期望值,将期望值与相应的测量值比较,并基于比较来产生推荐要采取的动作的咨询消息。

供应给各种机器或者由工厂中发电机产生的电力可以由与各机器关联的马达保护中继器248监控。典型地,该中继器248位于远离所监控装置的马达控制中心(MCC)或者向机器供电的开关设备250中。此外,对于保护中继器248,开关设备250还可以包含监控和数据采集***(SCADA),该SCADA向LMDS 213提供电源或者电力输送***(未示出)装置,其例如位于在开关站、或者远程传输线断路器和行参数的工厂。
图3是(图1所示的)可以与LMDS 213使用的示例性规则集280的框图。规则集280可以是一个或更多自定义规则、以及定义自定义规则的行为和状态的一系列性质的组合。规则和性质可以捆绑并存储为XML字符串的格式,当存储到文件时,其可以基于25个字符字母数字密钥加密。规则集280是模块化的知识单元,包含一个或更多的输入282和一个或更多的输出284。输入282可以是将数据从LMDS 213中的具***置指引至规则集280的软件端口。例如,来自泵外置振动传感器的输入可以传输至DCS 201中的硬件输入终端。DCS 201可以在该终端将信号采样,以接收其上的信号。信号然后可以处理并存储在存储器可访问的单元和/或集成到DCS 201。规则集280的第一输入286可以映射的至存储器的位置,使得存储器中该位置的内容作为输入对规则集280可用。类似地,输出288可以映射至存储器中的可由DCS 201访问的另一个位置或者映射至另一个存储器,使得存储器中的位置含有规则集280的输出288。
在示例性实施例中,规则集280包含涉及与在工厂中操作的装置的具体问题关联的监控和诊断的一个或更多的规则,工厂诸如例如是气体回注工厂、液化天然气(LNG)工厂、发电厂、炼油厂和化学处理设施。尽管关于与工厂一起使用而说明了规则集280,但规则集280可以适当组成为捕获任何知识并用于确定任何领域的解决方案。例如,规则集280可以含有关于经济行为、金融活动、天气现象和设计过程的知识。规则集280然后可以被用于确定这些领域中的问题的解决方案。规则集280包含来自一个或者很多源的知识,使得当适用了规则集280时,该知识传输至任何***。以规则的形式捕获的知识将输出284与输入282相关,使得输入282和输出284的规范允许规则集280适用到LMDS 213。规则集280可以仅包含针对具体工厂资产的规则,并可以仅针对与该具体工厂资产关联的一个可能的问题。例如,规则集280可以仅包含适用于马达或者马达/泵组合的规则。规则集280可以仅包含使用振动数据来确定马达/泵组合的健康的规则。规则集280还可以包含使用一套诊断工具来确定马达/泵组合的健康的规则,该套诊断工具除了包含振动分析技术外,还可以包含例如用于马达/泵组合的性能计算工具和/或金融计算工具。

在创建规则集280期间,该领域的人类专家使用通过编程一个或更多的规则的开发工具,透露对于具体资产特定的该领域的知识。规则通过产生输出284与输入282之间的关系的表达式来创建,使得不需要对规则编码。可以使用图形方法,例如使用在开发工具内建的图形用户界面上的拖放,从操作数的库选择的操作数。操作数的图示可以从屏幕显示器(未示出)的库部分选择,并拖放到规则创建部分。输入282与操作数之间的关系以逻辑显示方式布置,并且用户被提示输入值,诸如当适当基于具体操作数时的常数、以及选择的输入282的具体一个值。因为创建了需要捕获专家的知识的很多规则。相应地,规则集280可以包含一组强壮的诊断和/或监控规则、或者基于客户的要求以及规则集280的特定领域中的技术状态的一组相对不太强壮的诊断和/或监控规则。开发工具提供的资源用于在开发期间测试规则集280,以保证各种组合和输入282的值在输出284产生期待的输出。
图4是依据本公开的示例性实施例的规则构建工具400的屏幕截图。在示例性实施例中,工具400使用代表编程的操作的对象,其容易操纵来产生对于要监控的各辅助***参数特定的规则集。对象在操作选择区域402中选择,其由操作符选择标签404访问。功能选择标签406、热动力学算法标签408、以及构造标签410也可用于选择。对象被拖动到工作区域412,与标签关联的操作对象在工作区域412建立逻辑,来从测量的或者推断的参数产生输出。
图5是示出对于示例性辅助***过程参数、即罐差压过程参数的逻辑流程的分层流程图500。图500包含症状行502,用于列出可以由规则集表明需要注意的症状。列出担忧的症状源的标签以及符合产生咨询的参数或者状况。图500还包含行504,用于列出行502列出的症状潜在原因。动作行506列出诊断工程师遵循的指令,便于隔离出并可能地校正该源。在各种实施例中,诊断工程师是远程监控燃气涡轮机的操作的第三方。推荐行508列出对燃气涡轮机的操作员的推荐,其可以比传输给诊断工程师的动作更深入或者要求更多介入。
