| 摘 要： | 为了揭示电磁转矩系数的实质,证明了用电磁转矩系数表达电磁转矩只是某种近似,还证明了将单机系统的电磁转矩定义推广于多机系统,其前提条件是所研究的机组相对于惯性中心COI(center of inertia)只有1个运动模式;基于状态空间模型,提出了单机、2机和2机群的电磁转矩系数的定义,给出了理论计算方法.在多机情形下,...

| Abstract: | In order to investigate the essence of electrical torque coefficients,it is proved that the equation between active power and electric torque based on two coefficients is not satisfied completely and electric torque method lead to a simplified path of accurate power system model essentially.If the electric torque definition of single machine is applied to multi-machine system,the given machine must be dominated by only one oscillation mode on the center of inertia(COI).This paper also presents electric toqu... |
