Silicon Carbide Gto Thyristor Loss Model for Hvdc Application
With the increase in use of power electronics in transmission and distribution applications there is a growing demand for cost effective and highly efficient converters. Most of the utility applications have power electronics integrated in the system to improve the efficiency and functionality of the existing system. The development of semiconductor devices is vital for the growth of power elec...
متن کاملHvdc Based on Voltage Source Converter —a New Generation of Hvdc Technique
人类对电的认识和应用以及电力科学的发展首 先是从直流电开始的。1882年,法国物理学家 M·得 彼列茨进行了历史上第一次直流输电试验,将 1.5kW 、1.5~2kV的直流电通过电报线路驱动 57km 外的水泵旋转 ,这次试验虽然线路功耗高达 78%,几乎没有使用价值,但它标志着高电压、 远距离大容量输电的崭新开始。这次试验由于具备 发电、输电和用电设备,所以也被认为是世界上第 一个电力系统。1954 年,第一座高压直流(HVDC) 输电工程投入工业化运行,它是从瑞典本土至果特 兰(Gotland)岛之间的一条 20MW、100kV 海底电 缆直流输电线,线路全长 96km。1972 年,加拿大伊 尔河(Eel River)HVDC输电工程正式投入使用,这 座 20MW 、2×80kV背靠背式 HVDC输电工程以首 次全部采用晶闸管阀而著称于世。到目前为止,全 世界共有 70 多个 ...
متن کاملHigh Voltage Surge Arresters for Protection of Series Compensation and HVDC Converter Stations
The efficiency of overhead power lines can be increased by series compensation or HVDC transmission. These complex systems can be protected from overvoltages by metal oxide surge arresters. Both porcelain and polymer tube design surge arresters are used for these applications, however, polymer tube design surge arresters offer various advantages over porcelain arresters such as light weight, ex...
متن کاملForced Commutated HVDC Converters
Since the implementation of the first HVDC thyristor valve at Eel River (Canada) in the early 1970’s, HVDC transmission has experienced tremendous growth. As power systems grow and become more integrated, interconnections to neighboring ac systems are becoming increasingly necessary to enhance stability, security of supply, flexibility and for other economic benefits. Primarily for stability re...
متن کاملResearch of Bipolar HVDC Transmission Lines based on Traveling Wave Differential Protection
The principle of the traveling wave based differential protection for bipolar HVDC transmission lines is proposed in the paper. Unlike the traditional current differential protection, the quantity of current is replaced by the quantity of the traveling wave for comparison. The traveling wave at the remote end is transferred to the local end for comparison to the local traveling wave. For the bi...
