Embodiment Construction
[0074] The block diagram of the specific embodiment of the present invention is as figure 2 , the asynchronous parallel calculation method based on single-machine multi-core transient stability calculation efficiency of power grid includes the following steps:
[0075] (1) According to the requirements of power grid analysis and calculation, from the power flow topology model data of the power grid network, according to the composition of power grid equipment including generators, busbars, AC lines, transformers, transient stabilizers, DC equipment, etc., form the power grid transient stability analysis requirements failure set. Realize the power flow calculation based on the steady state model of the power grid, and form the base state operation mode of the power grid simulation calculation. The parameters of the transient stability model of the power grid established based on the level of the ground state power flow, mainly include the prime mover model of the generator in...
