Beschreibung
Zusammenfassung:	The invention belongs to the technical field of power system frequency stability calculation and analysis, particularly relates to a regional power grid inertia gravity center algorithm, and more completely relates to the crossing field of inertia calculation in the power system frequency stability field and plane gravity center calculation in physics. The method comprises the following steps: calculating node inertia and total inertia of a regional power grid; acquiring regional power grid node position information; obtaining a geographic coordinate axis of the regional power grid by using the obtained node position information of the regional power grid; calculating the inertia gravity center position of the regional power grid by using the geographic coordinate axis of the regional power grid; and obtaining regional power grid inertia gravity center comprehensive information according to the regional power grid inertia gravity center. According to the method, the inertia of each node of the regional power
