The invention discloses a method and device for building a closed-loop test platform suitable for multiple scenes. The method comprises a step of building a control protection system of multiple converters according to a hierarchical distribution principle, wherein the control protection system comprises monitoring systems, station control systems, pole modules and valve group modules, a pluralityof application programs corresponding to different application scenes are stored in the control protection system in advance, the application programs can call corresponding station control systems,pole modules and valve group modules according to corresponding application scenes such that a corresponding communication connection is established in the control protection system, a step of establishing a plurality of real-time simulation models according to the electrical main loops of the different application scenes, and a step of connecting the control protection system with a real-time simulation model through an optical fiber or a cable to form a closed-loop test platform. The invention provides the closed-loop test platform which can be flexibly adjusted and switched according to different application scenes so as to be quickly suitable for DC power transmission application type control protection systems of various major loop topologies.
Description
technical field [0001] The invention relates to the technical field of real-time simulation of direct current transmission systems, in particular to a method and device for building a closed-loop test platform applicable to various scenarios. Background technique [0002] Flexible DC transmission is an important development direction of DC transmission technology. It is widely used in offshore wind power grid connection, grid flexible interconnection, long-distance large-capacity power transmission and other occasions. Large-capacity flexible DC transmission is about to enter the UHV era. The world's first UHV hybrid multi-terminal DC transmission project is also under construction. The new features of UHV, three-terminal and hybrid DC, as well as complex and changeable operation modes, have outstanding innovation and demonstration effects, but are also full of technical challenges. The closed-loop real-time simulation system of the control and protection system is an import...
