Electromechanical-electromagnetic transient hybrid simulation negative resistance processing method and system

The invention provides an electromechanical device. The invention discloses an electromagnetic transient hybrid simulation negative resistance processing method and system, and the method comprises the steps: obtaining an equivalent circuit between a first bus and a second bus, and enabling the equivalent circuit to be in an electromechanical state; and during electromagnetic transient hybrid simulation, converting the equivalent circuit into an equivalent circuit. The circuit (equivalent circuit) after equivalence and the circuit (equivalent circuit) before equivalence are kept consistent onthe admittance matrix, the negative resistance can be converted into the positive resistance, the negative resistance appearing during simulation is replaced, and subsequent modeling is facilitated. 本发明提供了一种机电-电磁暂态混合仿真的负电阻处理方法和系统，其中方法包括：获取第一母线和第二母线之间的等值电路，在机电-电磁暂态混合仿真时，将所述等值电路转换为等效电路。本发明使得等效之后的电路(等效电路)与等效前的电路(等值电路)在导纳矩阵上保持一致，能够将负电阻转换为正电阻，代替了在仿真时出现的负电阻，有利于后续的建模。
