Abstract: Abstract:After the bypass system of the 300MW condensing generator set of Hubei Huadian Xiangyang Power Generation Company Limited was reformed, it is needed to modify and perfect correlative logic. The hidden danger, which may occurs after the bypass system was rformed, was analyzed, and relevant control logic optimization measures were proposed. The unit bypass system had been reformed for a year, the system was tested by different conditions and operated reliably and stably.
