The invention discloses a power angle stability-based direct current receiving end simultaneous stop overhaul scheme determination method and system. The method comprises the steps of for each alternative simultaneous stop overhaul scheme, calculating a whole network average power angle oscillation characteristic damping ratio corresponding to each power generator node fault in an electric network, and determining a risk level corresponding to each power generator node fault; calculating an electric network topology entropy value of each alternative simultaneous stop overhaul scheme; calculating a sum of a load motor ratio and a unit spinning reserve rate in a time period corresponding to each alternative simultaneous stop overhaul scheme; calculating a comprehensive risk assessment valueof each alternative simultaneous stop overhaul scheme; and according to the comprehensive risk assessment value of each alternative simultaneous stop overhaul scheme, determining an optimal simultaneous stop overhaul scheme.
