| 摘 要： | 提出一套机电暂态–电磁暂态混合仿真方案,包括接口母线的选取方法、机电暂态子系统对电磁暂态子系统的等效、等值电路正序和负序参数不相等情况的处理(基波负序补偿法),并采用最小二乘法求取3序基波电流来反映电磁暂态系统仿真结果对机电暂态网络的影响。仿真计算结果证明了该套仿真方案的有效性和可行性,解决了机电暂态网络发生各种对称和不对称故障复杂情况下局部电路的详细电磁暂态仿真问题,并通过了大型电网仿真的检验。

| Abstract: | An effective solution of electromechanical transient and electromagnetic transient hybrid simulation was proposed, including interface selection, mutual equivalence methods between electromechanical transient and electro-magnetic transient network. It is able to deal with the situation that the positive and negative sequence parameters of equiva-lence circuit are different. Least square method was adopted to obtain three-sequence fundamental frequency current which indicated the influence of electromagnetic... |
