Abstract: This paper conducts the statistical analysis on 123 typical cases of unit trip caused by the thermal control systems in the power generation enterprises nationwide in 2016. It concludes that the fault causes involve the system design and configuration, installation, maintenance and operation. Through the analysis, the pre-control measures to eliminate the potential risks are discussed from the aspects of the optimization of the control logics, the normalization of the systematic and technical management and the enhancement of the reliabilities of the thermal control system to further improve the security of the system, prevent the units from tripping and improve the reliabilities of the operation of the generation units and the power grids.

Key words: thermal power generation unit, thermal control system, fault, cause analysis, pre-control measure
