一种火电厂故障自动分析装置、方法及系统
摘要：
本发明涉及热工控制及自动化领域，公开了一种火电厂故障自动分析装置、方法及系统。该火电厂故障自动分析装置包括：采集模块，用于FSSS、DCS、ETS和发变阻故障录波器的数据；GPS模块，用于检查FSSS、DCS、ETS和发变阻故障录波器的GPS时钟；以及分析模块，用于在所述FSSS、DCS、ETS和发变阻故障录波器的GPS时钟相一致的情况下，根据所述DCS的数据、锅炉跳闸首出原因、汽轮机跳闸首出原因和发电机跳闸首出原因中的一者或多者分析出火电厂机组故障的首出原因；其中，采集的所述FSSS、所述ETS和所述发变阻故障录波器的数据分别示出所述锅炉跳闸首出原因、所述汽轮机跳闸首出原因和所述发电机跳闸首出原因。本发明能自动分析机组故障的原因，简化了人工分析过程。
摘要（英）：

The invention relates to the field of thermal control and automation, and discloses a fault automatic analysis device, method and system for a thermal power plant. The device comprises a collection module which is used for collecting the data of an FSSS, a DCS, an ETS and a generator-transformer unit fault recorder; a GPS module which is used for inspecting the GPS clocks of the FSSS, the DCS, the ETS and the generator-transformer unit fault recorder; and an analysis module which is used for analyzing a first-out cause of a set fault of the thermal power plant according to one of the data of the DCS, the first-out cause of boiler tripping, the first-out cause of turbine tripping and the first-out cause of generator tripping or more when the GPS clocks of the FSSS, the DCS, the ETS and the generator-transformer unit fault recorder are consistent with each other. The collected data of the FSSS, the ETS and the generator-transformer unit fault recorder respectively displays the first-out cause of boiler tripping, the first-out cause of turbine tripping and the first-out cause of generator tripping. The device can automatically analyze the cause of the fault of the unit, and simplifies the manual analysis process.
