基于新能源并网的多端柔性直流输电系统协调控制方法

Coordinated Control Method of Multi-terminal FLEXIBLE DC Transmission System Based on New Energy and Network

为解决传统直流输电系统协调控制波特率低的问题,设计新能源并网下多端柔性直流输电系统协调控制方法。采集多端柔性直流输电系统协调控制信号,计算多端柔性直流输电系统协调控制频率,实现多端柔性直流输电系统协调控制。设计实例分析,结果表明,设计方法控制波特率明显高于对照组,能够解决传统多端柔性直流输电系统协调控制波特率低的问题。

In order to solve the problem of low baud rate of coordinated control of multi-terminal FLEXIBLE DC transmission system based on traditional new energy and off-grid,the coordinated control method of multi-terminal FLEXIBLE DC transmission system based on new energy and off-grid is designed.The coordinated control signal of the MULTI-terminal FLEXIBLE DC transmission system is collected,and the coordinated control frequency of the multi-terminal FLEXIBLE DC transmission system is calculated to realize the coordinated control of the multi-terminal FLEXIBLE DC transmission system.The analysis of the design example shows that the baud rate controlled by the design method is obviously higher than that of the control group,which can solve the problem of low baud rate of coordinated control in the traditional multi-terminal FLEXIBLE DC transmission system.
