Embodiment Construction

[0054] The present invention will be further described below by taking the ±500kV Guiguang II HVDC transmission project as an example and in conjunction with the accompanying drawings.

[0055] The calculation process for the user to use the present invention to perform insulation coordination analysis on a Guiguang II HVDC power transmission project converter station is as follows: figure 1 shown.

[0056] First, go through the arrester configuration steps, such as figure 2 Shown:

[0057] (1) The user chooses the main wiring of the converter station: since Guiguang II is a ±500kV DC system, the user chooses the main wiring of the unipolar twelve-pulse converter bridge;

[0058] (2) The user inputs the basic parameters of the system; the rated power of the Guiguang II system is P r =3000MW, rated voltage U r =500kV, rated current I r =3kA, design firing angle α=15°, cut-off angle β=17°, DC line length l=1225km, DC line maximum operating voltage U dcm =515KV, current I ...

Abstract

A converter station insulating co-operating design method of a high-pressure direct-current power transmission system belongs to a high-pressure direct-current power transmission system analyzing method, and aims at simplifying calculating working capacity, avoiding excessive man-made interference, and guiding users to highly-effectively finish insulating co-operating analysis. The converter station insulating co-operating design method comprises the lightning arrester configuration step, the system analysis step and the insulating co-operating step. The converter station insulating co-operating design method greatly simplifies the calculating working capacity of insulating co-operating analysis, avoids excessive man-made interference factors of users, and guides users to highly-effectively finish insulating co-operating analysis through a guiding mode.

Description

technical field [0001] The invention belongs to an analysis method of a high voltage direct current transmission system. Background technique [0002] The insulation coordination of the power system is to comprehensively consider the various acting voltages (including working voltage and overvoltage) that the electrical equipment may bear in the system, the characteristics of the protection device and the withstand characteristics of the equipment insulation to various working voltages, and reasonably select the equipment Insulation level, so that the cost of equipment, maintenance costs and accident losses caused by equipment insulation failure, to achieve the highest overall benefits in terms of economy and safe operation. [0003] The insulation coordination design of the power system is to reasonably formulate the insulation tolerance level of the equipment in consideration of the overvoltage characteristics of the system, the configuration and performance of the protect...
