提出了一种改进的发电机聚合参数解析求解方法． 该方法首先通过加入等价移相变压器消除同调发电机合并至公共母线所带来的电压偏差，然后基于发电机结构的系数矩阵不变特性，利用发电机聚合前后在同步平面各轴系投影分量相等的特点，直接获取等值发电机模型参数． 文中方法能弥补传统的基于频域传递函数拟合和时域仿真优化的方法对工作点设置或寻优方向选取的依赖性，对发电机模型具有更强的适应性，更可应用

Proposed in this paper is an improved analytical method of generator aggregation parameters． This method
first adds a phase shift transformer to a common bus to eliminate the voltage deviation caused by moving coherent generators，and then directly obtains the parameters of the equivalent generating units based on the coefficient matrices structure preservation characteristic of the generator structure and the fact that the sum of the current phasor on every axis of the synchronous planes is equal． This method overcomes the deficiencies of the traditional methods，which depend on the transfer function fitting in the frequency domain or the time domain simulation and thus rely on the setting of working points and the selection of optimization directions． Therefore，the proposed method is more adaptive for generating unitsand can be applied to the on-line calculation．
