摘　　要：提出了一种新的轴系扭振响应计算方法；根据补偿原理导出了一种快速求解电网络方程的方法；利用四阶Ｒｕｎｇｅ－Ｋｕｔｔａ方法，实现了多机电力系统机电联合振荡的同步仿真计算．基于上述方法，开发了相应的机电耦合轴系扭振动态仿真程序ＭＥＤＰ。A new approachto the calculation of the torsional response of the turbogenerator shaftis proposed.A quick method for solving network equations is developed using the principleof Compensation. Numerical integration by the fourth-order Runge-Kutte method is success- fully used to carry out the synchronous simulation calculation of electro-mechanical coupledvibration of a power system with multiple machines. A dynamic simulating program,MEDP,for torsional vibration in electro-mechanical coupling is developed.
