The invention relates to a power distribution network real-time simulation time correction method and device. The method comprises the following steps: setting a virtual power supply in a slave simulation model in a power distribution network simulation model, obtaining the power supply voltage of a main simulation model and the virtual power supply voltage of the slave simulation model during the parallel simulation of the power distribution network simulation model, determining virtual power between the master simulation model and the slave simulation model according to the power supply voltage of the master simulation model and the virtual power supply voltage of the slave simulation model, and correcting simulation time of the slave simulation model according to the virtual power between the master simulation model and the slave simulation model. According to the technical scheme provided by the invention, by correcting the simulation time between the master simulation model and the slave simulation model, the problem of time synchronization among multiple simulation machines is solved, and safe and stable operation of the system is ensured.
Description
technical field [0001] The invention relates to the field of distribution network simulation, in particular to a method and device for real-time simulation time correction of a distribution network. Background technique [0002] The real-time simulation of the distribution network can interact with external physical equipment in real time. However, as the scale of the distribution network becomes larger and larger, the real-time simulation of the complex distribution network divides the distribution network model to achieve a substantial reduction in the order of the distribution network. The space capacity of the simulator is saved, the simulation time of the simulator is accelerated, and the real-time simulation of the distribution network model is realized. [0003] However, when the distribution network model is divided, the simulation of the distribution network is realized by multiple machines, and there may be corresponding errors due to time asynchrony between the mu...
