柔性直流输电网的电压控制原理研究

Research on Voltage Control Principle of Flexible HVDC Transmission Network

基于电压源换流器(VSC)的柔性直流输电技术出现以后,由于直流电流可以反向,直流电网的优势可以充分发挥,因而发展柔性直流电网技术已成为电力工业界的一个新的期望。但发展柔性直流电网除了在设备制造方面还存在瓶颈之外,在控制策略方面同样存在挑战。基于此,本文对柔性直流输电网的电压控制原理进行了探讨。

with the emergence of flexible dc transmission technology based on voltage source converter(VSC),the advantages of dc grid can be fully brought into play because the dc current can be reversed.Therefore,the development of flexible dc grid technology has become a new expectation of the power industry.However,in addition to the bottleneck in equipment manufacturing,the control strategy is also challenged.Based on this,this paper discusses the voltage control principle of flexible dc transmission network.
