Dynamic simulation system for substation

Abstract

The invention discloses a dynamic simulation system for a substation. The system comprises a host; a primary system model, a secondary system model and a dynamic graphics module are arranged in the host; the primary system model adopts a graph, model and database integration mode and comprises a substation simulation model; the substation simulation model includes a secondary side current model of a CT, a secondary side voltage model of a PT, an on-off state model and a transformer tap position model; the data of the primary system model is stored in a real-time database in real time; the secondary system model adopts a secondary graph-model mode; the exchange of variable data in the secondary system model and data in the real-time database is realized through the dynamic graphics module; and the host is connected with a real physical simulation device through an interface box. With the dynamic simulation system for the substation of the invention adopted, in-place monitoring and accurate monitoring can be carried out timely; online simulation can be realized; maintenance operators can carry out fault maintenance accurately; efficiency can be greatly improved; maintenance errors can be greatly reduced; and offline simulation can be realized. The dynamic simulation system for the substation has advantages of real simulation and better simulation results.

Description

technical field [0001] The invention relates to a dynamic simulation system for substations, belonging to the technical field of substations. Background technique [0002] Existing substation fault monitoring and fault maintenance are difficult to carry out at the same time. Due to the low professional level of maintenance operators and the monitoring accuracy of monitoring equipment, the fault monitoring data is unreliable, the maintenance efficiency of maintenance operators is low, and maintenance errors are prone to occur, which leads to the failure of the entire power grid. Operation has an impact. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dynamic simulation system for substations. Through the graphical model simulation mode, the real-time data of the substation can be matched, and when a fault occurs, it can be monitored in time and accurately. Under the guidance, fault maintenance can be completed ...
