Novel Voltage Source Converter based HVDC Transmission System for Offshore Wind Farms
Offshore wind farms have recently emerged as promising renewable energy sources. For increasing distances between offshore generation and onshore distribution grid, HVDC transmission systems based on voltage source converters can be a feasible and competitive solution. This thesis presents a comprehensive evaluation of a novel integrated wind farm topology that includes the generator drive syst...
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 کاملVoltage Source Convertor Topology for Hvdc Grid
Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connect alternative to conventional AC transmission above a certain cable length. This paper presents a new VSC transmission topology for HVDC grid connection of offshore wind farms.
متن کاملModel Predictive Control of Voltage Source Converter in a HVDC System
Model Predictive Control (MPC) method is a class of advanced control techniques most widely applied in industry. The major advantages of the MPC are its straightforward procedure which can be applied for both linear and nonlinear system. This paper proposes the use of MPC for voltage source converter (VSC) in a high voltage direct current (HVDC) system. A MPC controller is modeled based on the ...
