摘要

特高压直流大功率失去将对受端电网安全运行造成严重冲击。文中针对特高压直流大功率失去下的频率恢复、直流近区输电断面过载、联络线功率超用，以及系统旋转备用不足等稳态控制问题，提出了源网荷协调控制策略。利用可中断负荷，建立调度—营销协同及省地一体化的负荷控制架构，实现特高压故障情况下发电、负荷及电网的协调优化控制，为特高压受端电网应对直流大功率失去下的调度故障处置提供了参考及借鉴。

Abstract

It will be a serious impact on the receiving power system of safe operation when power of the ultra-high voltage direct current(UHVDC)system gets lost. A “source-grid-load” coordinated control strategy is proposed for steady control problems such as frequency restoring

transmission section overloading

tie-line power overusing

spinning reserve lacking

etc

with the power of the UHVDC system lost. By using interruptible loads

through integrated dispatch-marketing and provincial-regional control

the generation

load and grid coordinated optimization control is achieved

which provides an important reference for the dispatcher to cope with the receiving power system with the power of the UHVDC system lost.
