Problems solved by technology
More and more new technologies are introduced into the smart grid, such as simulation technology, but the existing smart grid simulation method only builds two out of the three, the primary system simulation, the secondary equipment simulation, and some real secondary equipment. The coordination and synchronous operation system among the participants does not constitute a complete simulation system

[0080] The invention provides a real-time simulation method of a smart grid, including:
[0081] Step A, building a primary system model and a secondary system model respectively;
[0082] Step B, after the primary system model calculates each step and obtains the simulation data, it is written into the real-time database, that is, the primary system model is always in the calculation state, and it will be written immediately after calculating each step In the real-time database; when the primary system model calculates any step length to obtain the simulation data and writes it into the real-time database, the analog signal conversion device and the secondary system model simultaneously read the simulation data from the real-time database. data, if the GOOSE signal conversion device and the secondary system model return information to the primary system model at the same time, the primary system model forms a new topology according to the returned information for simulation, ...

Abstract
The invention discloses a panoramic real-time simulation method for a power system, which comprises the following steps: respectively constructing a primary system model and a secondary system model of a substation; writing the simulation data of each step into the real-time database after the system model is calculated once. Once the system model has computed and written simulation data of any step size to the real-time database, the secondary system model collects the data from the real-time database; simultaneously, the primary system model transmits the simulation data to the signal converting device, and if the primary system model receives the action information sent by the secondary system model and simultaneously receives the information returned to the primary system model by thesignal converting device, the simulation is carried out according to the topology structure formed at present. The invention coordinates and synchronizes the primary system simulation, the secondary equipment simulation and part of the real secondary equipment, and has the interoperability, thereby forming a complete simulation test system, which can ensure the seamless docking of the simulation platform with the real secondary equipment and the virtual digital protection.
