The invention discloses a multi-task method for outputting a transient simulation calculation result of a power system. Channel processing and output management are carried out through different stream processors in a GPU program calculation is carried out through default streams in the GPU, data transmission and processing are carried out through non-default streams in the GPU, and finally, recording of channel files is completed. According to the embodiment of the invention, the problems that the number of observation channels is limited due to the channel output problem in the existing transient simulation process, the simulation speed is influenced by excessive channels, and the channels need to be set before simulation can be well solved. The simulation speed can be increased, channel setting is not online, and the problem of recalculation under the condition of channel missing is not needed. According to the method, the speed of simulation calculation can be improved, better software use experience can be provided for users, and then the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of power system simulation, in particular to a multi-task method for outputting calculation results of power system transient simulation. Background technique [0002] Due to the scale of the modern power system network and the large-scale increase in the calculation scale brought about by the application of large-scale power electronics technology, due to the need to ensure the efficiency of system calculation, the number of channel outputs for power system transient simulation will be limited to ensure the system operating efficiency. The limitation of the number of channels will lead to the limitation of the observation point of the system, and when there is an error in the channel setting, the channel must be reset before the simulation, which reduces the efficiency of the simulation. Contents of the invention [0003] The purpose of the present invention is to provide a multi-task method for the output of powe...
