Ultrahigh-voltage direct-current transmission simulation training method and device

Abstract

The invention relates to an ultrahigh-voltage direct-current transmission simulation training method and device. A simulation training service module acquires and stores SCADA real-time data; the simulation training service module receives an issued operation command, and then transmits the operation command and measurement point real-time data to a power system real-time model and a control protection model built with corresponding tools of Matlab, through corresponding access interfaces; the power system real-time model runs in an XPC real-time operating system; the models run dynamically and output results to the simulation training service module which uploads the results. The ultrahigh-voltage direct-current transmission power system model is built with the Matlab; after being complied, the power model runs in the XPC real-time operating system environment, and the model has response timeliness and high reliability; computing results are highly consistent to field actual operating system data in terms of both time and space; efficient data interaction is achieved through a packaged organic access interface; development efficiency is improved, development cost is saved, and practical value is good.

AI Technical Summary

Problems solved by technology

[0003] At present, the domestic existing HVDC-DTS simulation training system products are represented by Tsinghua simulation training system (hereinafter referred to as Tsinghua simulation system), its power system model is a self-developed model, and the blocking logic of partial protection is generated through the model, and the design ideas are compared Advanced, but due to the limitation of manpower, capital investment and technical level, the model is not mature enough, there are many defects, the real-time performance and accuracy of data are poor, and the fault tolerance is not good, especially in the locking logic. The complexity of the auxiliary logic is relatively complex. In this regard, the Tsinghua simulation system cannot provide a better solution. The system’s response to on-site problems is slow, and it is difficult to meet the user’s requirements.
