Parameters Selection and Arrangement of Smoothing Reactors for ±800 kV YunnanGuangzhou UHVDC Transmission Project
摘要
Abstract
To restrain the rising speed of fault current due to disturbance in UHVDC transmission system, avoid the discontinuity of direct current in light load condition,and reduce the harmonic at DC side, smoothing reactors are needed at the DC side outlet of the converter. On the basis of the main circuit structure of ±800 kV Yunnan-Guangzhou UHVDC Transmission System, the inductance values of the smoothing reactors are calculated in this paper. Because of the special connecting tructure of the converters of UHVDC system, the smoothing reactors arrangement is different from that of ±500 kV HVDC system. A simulation model of ±800 kV Yun-Guang UHVDC Transmission System based on PSCAD/EMTDC is built, and three arrangement schemes of smoothing reactors are compared in terms of harmonic characteristic and switching DC over-voltage via simulations.关键词
