The invention discloses a
data exchange method for electromechanical and electromagnetic transient
hybrid simulation and relates to the technical field of transient stability research and digital
simulation of power systems. The method comprises the following steps of: simulating an electromagnetic transient
simulation power grid to obtain the electromagnetic transient simulation data, simulating an electromechanical simulation
power grid to obtain the electromechanical simulation data,
processing the electromechanical simulation data to obtain a three-phase instantaneous value Thevenin
equivalent circuit model of the electromagnetic transient simulation
power grid, correcting a power supply frequency and transmitting the parameters of the three-phase instantaneous value Thevenin
equivalent circuit model to the electromagnetic transient simulation power grid through an interface
bus; and
processing the electromagnetic transient simulation data to obtain the active power and the reactive power injected into the electromechanical simulation power grid through the interface
bus and form an electromechanical simulation interface
bus model, so that the active power and the reactive power can be transmitted to the electromechanical simulation power grid. According to the
data exchange method for electromechanical and electromagnetic transient
hybrid simulation disclosed by the invention, the real-time simulation of the power grid in a relatively large scale is realized; and the
hybrid simulation is not limited by the scale of the power grid.
