CONVERTER PARAMETERIZED CONSTANT ADMITTANCE MODELING METHOD BASED ON CROSS INITIALIZATION

A converter parameterized constant admittance modeling method based on cross initialization, comprising the following steps: step (1), performing parameterization modeling on a converter, employing, by a switch, a parameter historical current source constant admittance model, and establishing, by other elements, a model on the basis of an EMTP theory; step (2), detecting whether state switching occurs, and if yes, performing cross initialization correction; step (3), determining model parameters, and establishing a whole-network equivalent admittance matrix and an injection current source to obtain an electromagnetic transient simulation equivalent model; step (4), solving for the network power flow according to a basic solving equation I=YU to obtain a simulation result of the electromagnetic transient model of the converter at a current time; and step (5), calculating an equivalent admittance matrix and an injection current source at a next time by means of the current network state quantity, and returning
