Abstract

The invention relates to a real-time digital hybrid simulation interface method based on frequency division impedance compensation. A studied power system network is divided into an electromechanicaltransient network and an electromagnetic transient network, simulation models of each network are established, the interface equivalent model of the electromechanical-electromagnetic transient networkis established according to frequency division impedance compensation interface algorithm, the corresponding data conversion model and interaction mode are established, and a real-time digital simulator is adopted to realize the electromechanical-electromagnetic transient real-time hybrid simulation.

Description

technical field [0001] The invention belongs to the technical field of power system transient digital simulation, in particular to a real-time digital hybrid simulation interface method based on frequency division impedance compensation. Background technique [0002] As a large number of power electronic equipment (especially a large number of renewable energy generation equipment) is connected to the grid, the operating characteristics and control characteristics of the grid become very complicated, and the strong nonlinear characteristics of the power system become increasingly prominent. The new trend of power system development has put forward higher requirements for power system simulation technology, that is, in the simulation process, it can not only simulate the electromechanical transient process of large-scale interconnected networks, but also simulate the electromagnetic transient process of local fast-changing power electronic devices. . Electromagnetic transien...
