Embodiment Construction

[0036] The following takes the Three Gorges to Shanghai DC transmission project as an example to illustrate the system debugging method of the DC transmission project.

[0037] The Three Gorges-Shanghai ±500kV DC transmission project is another ultra-high voltage, large-capacity DC transmission project in my country following the Gezhouba-Shanghai, Three Gorges-Changzhou, and Three Gorges-Guangdong DC transmission projects. Together with the Three Gorges-Changzhou and Gezhouba-Shanghai DC transmission projects, this project will constitute a powerful transmission channel for the Three Gorges Power Station to be sent to East China.

[0038] The rated transmission power of the Three Gorges-Shanghai DC transmission project is 1500MW for unipolar and 3000MW for bipolar; the rated DC voltage is ±500kV; the rated DC current is 3000A. The project starts from Yidu Converter Station in Yichang, Hubei near the Three Gorges Power Station in the west, passes through Hubei, Anhui, Jiangsu,...

Abstract

The invention provides a system debugging method for a high voltage direct current transmission project, which comprises the following steps: (1) compiling a system debugging outline; (2) implementing a system calculation and analysis as well as an analog simulation test; (3) establishing a system debugging proposal and a test plan of the system debugging; (4) monitoring the debugging work of a converter station on site; (5) technically monitoring the debugging work of the converter station; (6) according to the system debugging proposal compiled, implementing and completing the system debugging test; (7) summarizing the system debugging.

Description

technical field [0001] The invention relates to a system debugging method for a high-voltage direct current transmission project, belonging to the technical field of high-voltage direct current transmission. Background technique [0002] The high-voltage direct current transmission project is a project that realizes electric energy transmission in the form of direct current. With the gradual promotion of the application of high-voltage direct current transmission technology in power systems, direct current transmission and alternating current transmission cooperate to form a modern power system. Moreover, direct current transmission projects are moving toward Large-capacity, long-distance, and ultra-high voltage are developed. The commissioning of the DC transmission project is the last technical check before the project is put into operation. Therefore, the commissioning of the HVDC transmission system is a very complicated system engineering, involving a large number of p...
