Reliability Improvement of "Single Point Protection" of Main and Auxiliary Equipment in Thermal Power Plants

Zhang Guo-kun，Dong Li-jiang

[Abstract]By adding redundant protection measuring points of important auxiliary machines of two units，the singlepoint protection control logic of important auxiliary machines is optimized；multiple main protection measuring points and signal cables using the same cable are listed independently；In 2021，the reliability of thermal protection of the main and auxiliary equipment of China Coal Hami Power Generation Co.，Ltd. will be continuously improved，escorting the safe and stable operation of the unit.
