Abstract

The invention discloses an automatic transform system simulation calculation method in an energy internet system. The automatic transform system simulation calculation method comprises the steps of establishing an automatic transform system parameter model in a dispatcher training simulation system; after the dispatcher training simulation system starts training, creating an equipment state classobject and an automatic transform system model class object according to the automatic transform system parameter model, and establishing connection between the equipment state class object and the automatic transform system model class object based on signals and a slot mechanism. When the dispatcher training simulation system carries out training, the equipment state class object and the automatic transform system model class object communicate with each other to simulate the action logic process of the actual automatic transform system of a power grid. Invalid calculation of other irrelevant automatic transform system models is reduced, and the calculation efficiency is improved; the design idea of the method better conforms to the working principle of an automatic transform system in an actual power grid, and the method has universality and can be applied to simulation calculation of a protection device and a safety and stability control device.

Description

technical field [0001] The present invention relates to the technical field of the energy internet, in particular to a simulation calculation method for backup and self-injection in the energy internet system. Background technique [0002] Dispatcher Training Simulation System (DTS) is a computer simulation software for power grid dispatchers, which provides a simulation training environment completely consistent with the actual power system. The dispatcher simulates the state change process of the power grid after the power equipment fails in the DTS system, and performs fault location, isolation and restoration of power supply operations to improve emergency response capabilities and increase practical experience. After the failure of equipment in the power system, when the working power supply or working equipment is disconnected due to failure, the standby automatic switching device (AAT) can automatically and quickly put the backup power supply or backup equipment into ...
