Embodiment Construction

[0165] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0166] The present invention provides a ±800kV UHV DC transmission engineering system. The system includes a converter station at both ends and a DC transmission line. The converter stations at both ends are connected by the DC transmission line; the converter stations at both ends adopt bipolar conversion. Each pole converter includes two 12-pulse converters connected in series, and the series voltage is ±(400+400) kV in series;

[0167] The normal operating DC voltage of the single-ended converter station is ±800kV, and the operating DC voltage of the single 12-pulse converter is 400kV. The main circuit wiring diagram of ±800kV UHV DC transmission project provided by the present invention is as follows figure 1 Shown.

[0168] According to the design principles of ±800kV UHV DC transmission engineering, the main circuit has the followi...

Abstract

The invention relates to a debugging method for a + / - 800 kV ultra-high voltage direct-current transmission project system. The system comprises convertor stations at two ends and a direct-current transmission line. The debugging method for the + / - 800 kV ultra-high voltage direct-current transmission project system comprises the following steps that (I) the + / - 800 kV ultra-high voltage direct-current transmission project system is subjected to calculation and analysis; (II) a debugging scheme for the + / - 800 kV ultra-high voltage direct-current transmission project system is formed; (III) a debugging plan for the + / - 800 kV ultra-high voltage direct-current transmission project system is made; (IV) the + / - 800 kV ultra-high voltage direct-current transmission project system is subjected to a field debugging test; (V) the + / - 800 kV ultra-high voltage direct-current transmission project system is subjected to a pilot run; (VI) the + / - 800 kV ultra-high voltage direct-current transmission project system is subjected to a debugging summary. According to the debugging method for the + / - 800 kV ultra-high voltage direct-current transmission project system, a single current converter and a monopolar and bipolar system debugging test are combined for the first time, therefore, the efficiency of a system debugging test is improved, the system debugging speed is increased, good conditions are created for finishing system debugging in advance, and experience and reference are provided for the debugging of a direct-current transmission project system in future.

Description

Technical field [0001] The invention relates to the field of UHV DC transmission, in particular to a ±800kV UHV DC transmission engineering system and a debugging method thereof. Background technique [0002] The ±800kV UHV DC transmission project is to transmit electric energy in the form of direct current. Compared with the ±500kV DC transmission project, it is characterized by large transmission power capacity, long distance, more than 2000km, multiple main circuit wiring operation modes, and complex system structure. The commissioning of the UHV DC transmission system is a very complex system project. It involves more primary and secondary equipment of the DC project than the ±500kV DC transmission project, more test items, and the operation mode of the AC system, which requires careful assessment and Inspection and system debugging are closely combined with the characteristics of UHV DC transmission projects to carry out the power flow and stability calculation of the sendin...
