Abstract: Based on the system investigation and the data processing, combining with the practical situation of Gansu Datang Xigu Cogeneration Power Corporation Limited ,the settlement method of the power grid and the power plant was studied. According to the study result, the startup and standby high voltage auxiliary power system for 330MW cogeneration units was reformed, and the mutual supply of auxiliary power between adjacent units was realized, which reduces the offgrid energy of the power plant.

Key words: heat and power cogeneration unit, mutual supply power source, scope of reformation, security, economical efficiency
