大规模新能源接入弱同步支撑直流送端电网的运行控制技术综述

Reviews of Control Technologies of Large-Scale Renewable Energy Connected to Weakly-Synchronized Sending-End DC Power Grid

随着我国科学技术水平的不断发展与进步,开辟新能源成为当前需要关注的重点问题。本文主要从频率调节、无功电压控制及次同步振荡机理与抑制技术这三个方面对运行控制技术进行综述,并针对新能源大规模发展过程中的一些盲点提出亟待研究的内容,对新能源大规模发展的前景进行展望。

With the continuous development and progress of science and technology in China,the development of new energy has become a key issue to be concerned.This paper summarized the operation control technology from three aspects:frequency regulation,reactive voltage control,subsynchronous oscillation mechanism and suppression technology,and put forward some urgent research contents in view of some blind spots in the process of large-scale development of new energy,and looked forward to the prospect of large-scale development of new energy.
