Based on the quantification analysis of DSR

to take the energy internet as the research background and the power control system as the research object

the paper studies the optimal reclosing and emergency control respectively. According to different fault types to choose the best combination of control strategy

through selecting the best security and economic emergency control program

using the principle of wave superposition

the two impulse of the reclosing failure is superimposed on the system after emergency control

and to make the coincidence impact in favor of the convergence of the maximum angle difference and make the system quickly restore stable state. In this paper

a comparison study is carried out on the case of symmetric and asymmetric faults

and the data verified the validity and practicability of the method of matching optimization of power system reclosing and emergency control based on DSR. Algorithm is conducive to the reliable interconnection of the power system control network and other interconnected network

and to achieve the healthy development of the entire energy ecosystem.
