摘要

海底电缆较大的充电功率导致海上风电输电系统的工频过电压较严重

可采用高压并联电抗器进行限制。文中以中国某220 kV海上风电场为例

对其工频过电压进行了理论计算

并利用电磁暂态计算程序(alternative transient program-electro magnetic transient program

ATP-EMTP)建立了海上风电场经交流海缆送出系统模型

计算了输电系统工频过电压分布

进而对高压并联电抗器配置方案进行了分析。研究表明系统侧甩负荷过电压远大于风场侧甩负荷过电压;总补偿度相同时

在陆上进行单端补偿的效果略优于双端补偿。在此基础上给定了该海上风电场工频过电压限制的高压并联电抗器配置方案

并计算了不同海缆长度下所需的最小补偿度

为工程设计及设备选型提供技术依据。

Abstract

The serious power frequency over voltage of offshore wind power transmission system due to higher charging power of submarine cables can be limited by the use of high-voltage shunt reactor. In this paper

one 220 kV offshore wind farm in China is taken as an example

its power frequency over voltage is calculated theoretically and the transmission system model of offshore wind farm through AC submarine cable is set up by using alternative transient program-electro magnetic transient program（ATP-EMTP）. The power frequency over-voltage distribution of offshore wind farm transmission system is calculated

and then the configuration of high voltage shunt reactor is analyzed.The results show that the load dropping over-voltage at the system side is much larger that at the wind farm side. In case of same total compensation degree

the effect of single terminal compensation in land is slightly better than that of double terminal compensation. On this basis

the high voltage reactor configuration of the offshore wind farm to limit power frequency over-voltage is given

and the minimum compensation degree required under different length of submarine cable is calculated

which provides technical basis for engineering design and equipment selection.
