Abstract In accordance with the practical operational situation of distributed control systems（DCS）in certain fossil-fired power plants under Anhui electric power grid，the faults and hidden hermits in DCS systems of which affecting safety operation of the power units are analyzed and investigated from several areas，e. g. ，DCS modules，application software，network communication，and power supply. Positive suggestions for enhancing applicable level of DCS in fossil-fired power plants are contributed.
