The generator self-excitation is the most important issue in the black-start scheme calibration. In the early stage of black-start,once generator self-excitation happens,it not only causes the damage of generator and other elec-trical equipment,but also affects the later stage of black-start and causes the failure of the black-start. It means that the black-start scheme is invalid. In this article,the mathematical principle,physical process and all kinds criterion of self-excitation is introduced firstly,and then the Taipingshao hydropower station in Dandong is chosen as black-start power supply. The simulation model on PSCAD/EMTDC platform is accomplished according to the selected black-start path structure. The results verify Dandong power grid black-start scheme is valid.
