| 摘 要： | 结合规划中的山东与华北电网互联工程，给出适合评估联网后原山东电网内部低频振荡模式变化趋势的方法。通过跟踪互联前后原系统中弱阻尼振荡模式，借助振荡模态图，分析低频振荡问题受联网影响的变化趋势。对联网后原山东电网内部低频振荡模式的变化，联络线交换功率对振荡模式的影响等问题进行计算分析，总结出电网互联对山东电网内部2类低频振荡模式影响的规律。

| Abstract: | Approaches are presented to assess the low frequency oscillation modes of Shandong Power System as affected by power system interconnection between North China and Shandong Power Systems in the near future. To trace the changes of low frequency oscillation modes, the possible modes of the interconnected power systems are compared with the original modes of the stand-alone Shandong Power System aided by mode shapes analysis. Some oscillation stability problems are simulated including the changing tendency of the low frequency oscillation modes of Shandong Power System and the effect of power transfer of tie lines on different low frequency oscillation modes. |
