交直流协控技术在大电网的应用及配置
摘要
基于华中电网跨区交直流"送受并存"的特点
采用交直流协控技术
当受入型直流故障后
调制送出型直流功率
以减少不平衡功率在特高压长南线、500 k V交流电网的转移量
进而保持系统稳定运行
消除大功率大范围转移可能引发的"次生灾害"
同时避免大量切除负荷减少对民生的影响。该技术已在德宝直流、天中特高压直流工程中应用
有效提高了直流工程和长南线综合输送能力。随着特高压电网发展
交直流协控技术将得到更广泛地应用。
Abstract
Based on the characteristics of coexistent of receiving and sending
DC sending power is modulated to reduce the unbalanced power transfer in UHA Changnan line and 500 k V AC grid
remain system reliable operation
eliminate the faults caused by the transfer of large-scale high power and avoid the influence of people’s livelihood by AC / DC coordinated control technology. The AC / DC coordinated control technology has been used on Debao DC and Tianzhong UHV DC
which enhances the comprehensive transfer capability of both DC and Changnan AC line successfully. With the development of UHV
AC / DC coordinated control technology will obtain more and more application.
