摘要:
为了解决异步电机软起动仿真中,因电机模型不准确带来的误差问题,通过对起动过程中电机等效电路参数变化规律的研究,提出一种变参数异步电机模型用于软起动仿真.该模型基于异步电机工作原理,直接通过电机铭牌额定数据估算起动和稳态时的等效电路参数,其中转子电阻和转子漏抗在起动过程中随转速的上升而变化,确保在关键运行点上的电机仿真计算性能与真实电机基本一致.在Matlab中建立了变参数异步电机和软起动仿真模型,对16 MW样机进行电流斜坡起动仿真,起动时间与现场实际起动时间的误差不超过3%.实验证明,该模型简单易行,且具有较高的精度,可以有效地模拟异步电机起动过程.
Abstract:
In order to reduce the error introduced by the conventional motor model in the induction motor soft starting simulation, an induction motor model with variable parameters is proposed by investigating the variation patterns of the equivalent circuit parameters during starting. Based on the operating principle of the induction motor, the proposed model estimates the motor equivalent circuit parameters in starting and steady state directly from the nameplate data. During starting, the rotor resistance and leakage reactance are varied according to the increasing rotor speed to ensure that the simulation model is close to the actual motor on critical operating points. The proposed model is applied to soft starting simulation of a 16MW induction motor in Matlab. Simulation results are verified by experiment and the variation of the starting time is within 3%. It can be seen that the proposed model is simple in construction and high in accuracy, and can simulate the starting procedure of the induction motor validly.
