摘要
以abc相坐标建立与系统侧直接接口的同步发电机模型,参考节点取自发电机中性点,相应地电机定子绕组电压为机端节点电压,定子绕组电流则相应成为节点注入电流。系统侧与同步发电机直接接口,消除了预测校正和机网接口环节,可以有效地提高同等条件下的运算速度和仿真精度。
We used the phase coordinates model to simulate the generator,so that could directly connect with the system.The reference node was taken from the generator neutral point.Accordingly,the voltage of the stator winding was the terminal node voltage,and the current of the stator winding was the node injection current.Generator with the system was synchronous.Therefore,it could eliminate the generator system interface and avoid forecast correction.The computing speed and simulation accuracy could effectively improve under the same conditions.
