Abstract: In this paper, 148 typical cases involving system design, configuration, installation, maintenance and operation are selected and categorized from the collection of the thermal control system faults that occurred in the power plants nationwide throughout 2017. Through the statistical analysis of these typical cases, regarding the problems including the aging of the control system and auxiliary equipments, inadequate testing and maintenance of the automatic system, high failure rate of the on-site standalone control devices and repetitive occurrence of the typical faults, etc., the relevant pre-control measures and suggestions to further eliminate the potential risks and improve the system reliabilities are proposed such as equipment degradation analysis and upgrading, automatic system quality maintenance, specification normalization and implementation, and strengthening the effectiveness of the technical management and the personnel training.

Key words: thermal power plant, thermal control system, fault, statistic and analysis, suggestion
