| 摘要: |
| 对电力稳定控制系统中母线低频低压减载这一运行故障处理的控制策略进行了分析。以18条运行负荷线路为例,列出其最优策略数学模型。分别用穷举法、过切法、动态规划法加以实现,比较各自运算过程、计算分析次数以及特点和不足。结果显示:动态规划法相比于穷举法计算量少、计算结果丰富;相比于过切法,计算量没有大的增加且计算结果准确。 |

| Abstract: |
| The low-frequency and low-voltage load reduction control strategy of power system stability control system is analyzed.Mathematical model of the optimal strategy is established for eighteen load lines as an example.The exhaustedness approach,over switching-off method and dynamic planning method are applied respectively with comparison of operation process,computing time,merits and deficiencies.Results show that,compared with exhaustedness approach,dynamic planning method achieves richer result with less computing;while compared with over switching-off method,it achieves more precise result with a little more computing. |
