华电红雁池发电厂设备状态检修管理研究

摘要随着电力体制的改革，电厂在经济上将独立核算，削减运行维修费用成为发电企业降低发电成本的首选目标，状态检修必将得到广泛的重视。本文以华电红雁池发电厂（以下简称华电红电）设备检修为研究对象，首先综述设备检修中事后检修方式、预防检修方式和状态检修方式各自的优缺点；其次分析华电红电设备检修的现状及存在问题，实行状态检修的必要性和可行性；应用可靠性管理理论建立华电红电设备故障分布的数学模型，对华电红电设备可靠性进行分析和预测；探讨了华电红电设备状态检修的技术构架；针对主设备、主要辅机和辅助设备分别采取不同的检测技术，并建立设备状态数据中心，利用采集到的数据对设备运行状况进行预测和分析，针对设备的运行状态确定不同的检修计划；昀后探讨了华电红电设备状态检修管理问题，包括数据综合管理、备品备件管理、检修人员管理以及优化检修计划的内容，提出华电红电设备状态检修方案的实施措施。关键词：设备管理，可靠性，状态监测，状态检修AbstractThepaperaimattheHuadianHongyanchipowerplant;narrateseveralwaysofequipmentexaminingandrepairingandtheiradvantageanddisadvantageatfirst；pointoutthesignificanceofpractiseconditionmaintenanceintheHuadianHongyanchipowerplant.Then,thepaperanalysistheactualityandshortageofthepowerplant;setupmathematicalmodelofthepowerplantbasedonthetheoryofreliability；validatefaultprobabilityoftheequipmentdiagnoseandprognosisthereliabilityoftheequipmentsinthepowerplant；constructthetechnologyframeofthepowerplantonthebasisoftheformerwork:adoptdifferentexaminingmeansfordifferenttypeofequipment；explainthereasonforadoptingcorrespondingmethodandthewaysmeasuremethod；setupthedatabaseofequipmentcondition;analysistheequipmentconditionscientificallymakinguseofthesisdatatogetholdoftheequipmenthealthcondition.Atlast,designtheconditionmaintenanceandmanagementmode.QiJi(IndustrialEngineering)Directedbyprof.ZhouJianGouKEYWORDS:EquipmentManagement,Reliability,ConditionMonitoring,ConditionMaintenance目录中文摘要英文摘要第一章绪论...................................................................................................................11.1研究的背景及意义.................................................................................................11.2本论文的研究目的、主要工作..............................................................................21.3论文的研究思路及框架.........................................................................................3第二章设备检修理论综述.............................................................................................42.1设备检修及有关检修方式概述..............................................................................42.1.1事后检修方式................................................................................................42.1.2预防检修方式................................................................................................42.1.3状态检修方式................................................................................................52.1.4三种设备检修方式评述.................................................................................62.2设备状态检修方式的现状及发展趋势..................................................................82.2.1国内电力设备状态检修的现状及发展趋势...................................................82.2.2国外电力设备状态检修的现状及发展趋势.................................................102.2.3国内外电力设备状态检修的成效................................................................12第三章对华电红电设备检修问题分析与相应对策的设想..........................................133.1华电红电设备检修现状.......................................................................................133.1.1企业概况......................................................................................................133.1.2华电红电设备检修的流程...........................................................................143.1.3华电红电设备检修的管理...........................................................................153.2华电红电设备检修中存在的问题........................................................................163.2.1缺乏经济性与科学性...................................................................................163.2.2现有的检修方式不适应电力企业的改革和发展.........................................163.2.3检修人员素质较低，不能完全胜任设备的检修.........................................173.2.4检修方式不灵活，不能迅速处理突发事件，效率低下..............................173.2.5备品备件储备不合理，造成企业大量资金的积压.....................................173.3对提高华电红电设备检修水平的基本原则与主要措施的设想...........................173.3.1提高华电红电实施设备状态检修水平的基本原则.....................................183.3.1.1保证设备的安全运行..............................................................................183.3.1.2总体规划，分步实施，先行试点，逐步推进.........................................183.3.1.3充分运用现有的技术手段，适当配置监测设备.....................................193.3.2对提高华电红电设备检修水平的主要措施的设想.....................................193.3.2.1建立华电红电设备状态检修可靠性管理系统.........................................193.3.2.2选择适合华电红电设备状态检修系统的技术构架.................................203.3.2.3搞好华电红电设备状态检修工作的常规管理.........................................20第四章建立华电红电设备状态检修可靠性管理系统.................................................224.1华电红电设备的故障分布概率验证....................................................................224.1.1华电红电设备故障的可靠性数据分布........................................................244.1.2华电红电设备故障数据的选取及处理........................................................254.1.3基于可靠性数据分布的数值检验法的应用.................................................254.2华电红电设备可靠性分析...................................................................................284.3华电红电设备状态预测.......................................................................................294.4华电红电设备可靠性管理系统............................................................................31第五章选择
