Network dynamic and static hybrid calculation method based on D-Q electrical network electromagnetic transient modeling

The invention discloses a network dynamic and static hybrid calculation method based on D-Q electrical network electromagnetic transient modeling. The method comprises the following steps: step 1, determining division of a local dynamic region and a static region; 2, constructing a unified differential-algebraic relational expression for describing the dynamic and static hybrid network based on a D-Q electric network full-order model; step 3, algebraizing the relational expression describing the dynamic network through an implicit trapezoidal integral method, and then simultaneously establishing the relational expression with the algebraic relational expression of the static region to form a network global algebraic relational expression; 4, solving the nonlinear relational expression by adopting a Newton method, and analyzing a network dynamic process through a numerical calculation result; the method provides a new thought and reference for high-frequency dynamic characteristic analysis of a novel power sys
