Then based on the best slip formula of three-phase asynchronous motor total loss smallest, permanent best slip U/f coordination control strategy was proposed.
5Hz的输出带电机平稳运行;然后通过推导三相异步电动机总损耗最小的最佳转差率公式,提出恒最佳转差率U/f协调控制策略,在电机轻载时它通过U/f协调控制提高了异步电动机效率和功率因数,实现了全变频范围力能指标最优的控制目标;最后在设计制作六脉波的晶闸管换流电路、专用换流变压器和控制保护电路、开发控制保护软件程序的基础上搭建了六脉波双变量交交变频调速系统实验平台,在不同分频下验证理论研究成果和控制效果,并与仿真实验对比分析。
