| Abstract: | By analyzing the features of power system black-start, the basic principles of arrangement for the protective devices are presented. The line protection scheme with zero-sequence current protection and distance protection as the main protection is proposed for the radial system with a single power source during the initial stage of black-start, Based on the analysis of zero- sequence current distribution of earth faults under different operating conditions, a method of determining the settings of the zero-sequence current protection is also presented, A numerical example is given to demonstrate the effectiveness of the proposed principle and method. |
