Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] A method for automatically generating a fault circuit in a direct current transmission project. First, a circuit template file is established based on actual direct current project structure information, mainly including three types of equipment configuration circuits, DC switchyard configuration circuits, and lightning arrester configuration circuits. The equipment configuration circuit is divided into three layers of sub-circuits. Certain switching devices are preset at key positions in the second layer of sub-circuits, including circuit breakers and isolating switches. Various fault circuits are generated by selecting the operating status of the switching devices. Build corresponding control and protection circuits for each fault circuit in the main circuit, set up certain ID numbers for these configuration circuits, each part of each layer circuit and related...

Abstract

The invention discloses a direct current power transmission engineering fault circuit automatic generating method. Through a linked file and an ID (Identity) number, a primary loop sub circuit structure module, an equipment model and a circuit element model in direct current engineering and a control and protection circuit module in a switch device and a secondary loop are associated with the configuration of a relevant arrester; a fault configuration file is built through selecting the operation state of a switch; and finally, a fault circuit is automatically generated. Through associating the ID numbers and combining the direct current engineering equipment information file and the arrester scheme configuration information file, the equivalent circuit diagram generation and the direct current engineering fault circuit network topology modeling with the arrester and the control protection scheme are completed. A user can complete a direct current engineering instantiation application only through configuring certain fault files; the modeling on each kind of fault is not needed; the workload of direct current engineering fault network topology equivalence and modeling is greatly reduced; and the direct current engineering fault modeling efficiency is improved.

Description

technical field [0001] The invention belongs to the field of high-voltage direct current transmission system analysis, and in particular relates to a method for automatically generating a fault circuit in a direct current transmission project. Background technique [0002] At present, my country's high-voltage direct current transmission system is mainly responsible for the important tasks of long-distance, large-capacity power transmission and regional power grid interconnection. Once the DC transmission system suffers from overvoltage caused by lightning, operation, failure or other reasons, once the equipment insulation breakdown accident causes the DC system to shut down, it may cause the load center to lose large-capacity power supply, and then endanger the regional power grid. The consequences will be very serious, especially the damage to a large-scale AC-DC hybrid system like my country's Southern Power Grid will be unimaginable. In recent years, with the rapid devel...
