四、具体案例: 贵州省纳雍电厂4×300MW机组  案例研究
    1. 案例简介
    贵州省纳雍电厂隶属于贵州省电力公司,电厂坐落于贵州省毕节地区纳雍县城西南方向的阳长镇字库村,距县城约33公里,距六盘水70公里。213省道从电厂东面穿过,公路运输较为便利。县境内无铁路经过。离纳雍县最近的铁路站是位于水城境内的滥坝火车站,距阳长镇42公里。
    纳雍发电厂是位于纳雍煤矿区附近的一座大型坑口火电厂,就地消化纳雍县生产的无烟煤,缓解运输条件对纳雍煤炭生产的限制,促进了当地煤炭工业的发展,并带动全县经济的发展。电力将送入贵州主网分配,不仅可满足贵州电网负荷发展的需要,提高电网运行的可靠性及供电质量,而且可通过电网向广东等周边省份送电,实现“西电东送”发展战略。工程为4X30万千瓦机组建成后,总装机容量达120万千瓦,将成为贵州电网的主力电厂之一。3805E
    该工程4X300MW机组锅炉每小时耗煤量按设计煤种计算为513.2吨,年耗煤量约308万吨,全部通过公路运输。按载重量10吨的自卸汽车考虑,日最大进厂运煤车辆为1232辆。汽轮机采用亚临界、一次中间再热、单轴、高中压合缸、双缸两排汽、凝汽式汽轮机。额定功率300MW,主蒸汽流量937.86t/h,最大连续功率336.323MW。发电机最大连续输出功率333MW,额定功率300MW,额定功率因素0.85,水、氢、氢冷却方式。2002年8月,1#~4#汽轮机组,4×300MW,共安装了8套EN8000系统。
    2. EN8000系统结构
    贵州纳雍二电厂4台汽轮发电机组的配置相同。单台汽轮发电机组主机及辅机分别配置一个高速智能数采箱,两个数采箱配置在同一个标准机柜内,机柜内安装汽轮发电机组主机及其辅机的数采箱(下位机)和一个CRT显示器以及相应的接线端子。主机及辅机共用一套EN8000系统上位机工程师站。CRT显示器可显示每台机组主辅机的主监视图及各种分析数据图表。每台机组的下位机数采系统通过以态网与上位机工程师站相连,将数据上传至我公司的远程诊断中心并与电厂或省公司网域相连。系统下位机4台机柜安装于电子设备间内;系统上位机、显示器和打印机等设备视现场条件确定布置方案。
    3.EN8000系统安装描述
    纳雍电厂1#-4#机组共安装EN8000振动监测故障诊断专家系统8套,用于监测机组运行情况。
    1#机组由大机TSI之框架1的“DATA DYNAMIC 1”将机组的轴振和瓦振信号引入TDM系统。键相信号由大机TSI之框架1引入TDM系统。
    2#机组由大机TSI之框架1的“DATA DYNAMIC 1”将机组的轴振和瓦振信号引入TDM系统。键相信号由大机TSI之框架1引入TDM系统。
    3#机组由大机TSI之框架1的“DATA DYNAMIC 1”和“DATA DYNAMIC 2”将机组的轴振和瓦振信号引入TDM系统。键相信号由大机TSI之框架1引入TDM系统。
    4#机组由大机TSI之框架1的“DATA DYNAMIC 1”和“DATA DYNAMIC 2”将机组的轴振和瓦振信号引入TDM系统。键相信号由大机TSI之框架1引入TDM系统。
    在我公司工作人员认真、细致、周到地工作服务下,整个EN8000振动监测故障诊断专家系统至今仍在纳雍电厂的发电机组上正常运行。
所有这一切,都将有力地保证本项目在技术上处于世界先进水平,并保证本项目顺利实施、成功投用和长期稳定的运行,为机组安全、经济运行发挥重要作用。
