| 摘要: |
| 根据电路的基本理论，在一定假设条件下推导得出发电机有功输出功率与其在输电线路上的功率份额近似呈线性关系。针对用于发电权交易的线路潮流安全校核的灵敏度法计算精度不高的问题，采用最小二乘拟合技术求得具有统计意义的发电机有功输出功率线性分布因子。与基于灵敏度方法求得的功率分布因子相比，所提方法计及了有功和无功潮流的耦合。IEEE 3机9节点系统的分析结果表明，当发电机出力在额定范围内进行较大调整时，依照该因子进行线路潮流的快速计算更加精确。 |

| Abstract: |
| According to the circuit theory and some reasonable assumptions，the approximate linear relationship between generation and its components is deduced. As the precision of sensitivity method applied for the security check of generation rights trade is low，the least square fitting technique is used to calculate the statistically significant generation linear distribution factors． Compared with the sensitivity method，the proposed method considers the coupling between active and reactive power flows. Analytical results of IEEE 3-generator 9-bus system show that，when the generation output is adjusted greatly in a rated scale，the proposed method is more accurate. |
