摘要
对舰船电网环境给定子磁链定向矢量控制算法带来的影响进行了理论分析,对舰用双馈调速系统进行了数学建模和仿真建模,并在实际电机系统上进行了试验。仿真与试验结果表明:在舰船电网电压、频率存在较大稳态波动的情况下,双馈调速系统动态响应快、调速精度高,其稳态调速率不超过±0.2%,瞬态调速率不超过±0.5%,大大优于现有的舰船异步电动机调速系统。
The theoretical application of stator flux oriented vector control in electric network on naval vessels was analyzed,the mathematic and simulation models were established for the double-fed system of naval vessels,and then the experiments on a real electric machine were done. The simulation and experiment results showed that the double-fed system could work well in the electric network on naval vessels,the voltage and frequency’s range of which were wide. The response of double-fed system was fast and the speed regulation was accurate,the ratio of steady-state speed regulation was less than ± 0. 2% and the ratio of dynamic speed regulation was less than ± 0. 5% , which were greatly better than the existing speed regulation system on naval vessels.
