摘要(Abstract)：

针对采用柔性直流方法评估含特/超高压直流的弱送端电网安全无法抵抗系统潮流转移以及系统功能失衡的动态波动问题,安全稳定评估性能差,提出基于弹性映射的弱送端电网安全品质评估方法。设计了含特/超高压直流的弱送端电网三道防线安全稳定控制流程,分析弱送端电网弹性力学空间映射、弱送端电网交流支路映射模型以及交流支路的映射弹性势能的内容,将弱送端电网当成一条"源-网-荷"弹性支路,将广义弹性系数作为弱送端电网安全性能快速量化评估判据,管理人员对广义弹性系数曲线实施检测,则可完成弱送端电网安全状态的在线评估。实验结果说明,所提方法能够实现弱送端电网安全品质的准确评估,确保电网的稳定运行。
