| 摘 要： | 详细阐述了静态安全分析辅助决策的快速计算方法。在常规灵敏度算法的基础上,提出了计算支路开断分布因子的方法,并利用基态潮流方式下的灵敏度及开断分布因子,快速计算设备开断以后的节点注入功率对支路功率的开断灵敏度。依据开断灵敏度等量配对法原理,按照每台发电机对越限支路灵敏度和最大缓解量进行排序,形成辅助决策表。辅助决策过程只是在原有网络分析基础上增加了少量的计算,计算过程能够满足在线应用要求,实际系统的验算结果证明了方法的正确性。 |
| 关 键 词： | 静态安全分析 灵敏度 开断分布因子 辅助决策 |

| Abstract: | The algorithm of assistant decision-making for static security analysis is described in the paper. Based on the conventional sensitivity method, a new method is introduced to calculate outage distribution factors and the outage sensitivity which can reflect the relationship between node power and branch power after an element is out of service. Assistant decision-making for static security analysis can be easily acquired with the help of equal and opposite quantities in pairs for strategy of outage sensitivity. The assistant decision- making can satisfy the requirement of on-line application. Simulation results on real power system show that the proposed method is effective. |
| Keywords: | static security analysis sensitivity outage distribution factor assistant decision-making |
