in addition, the paper simulate a parameter identification method which doesn「t need no-load test to resolve the limitations of the method used by system. the result show that the method is feasible.
另外,针对于本文所采用辨识方法需要进行空载试验的局限性,还对一种不需要空载试验的参数离线辨识方法进行仿真试验,试验结果表明该方法可行。
developed the device manufacturers, installation, debugging, and then for no-load test and actual field test.
所研制的装置经制造、安装、调试,然后进行空载试车和实际现场应用试验。
the modifications were prompted by results of a no-load test of the pump in the us that showed the original design wouldn」t work correctly westinghouse said.
这些修改是由无在美国泵,发现原设计将无法正常工作负载测试结果提示,西屋电气公司说。
at present, most methods of the parameter identification need no-load test and locked rotor test.
该方法无需做堵转和空载实验,即可得到电机无速度传感器矢量控制系统中所需要的全部参数。
in the no-load test of transformer, because of the low power factor and non-sinusoid current waveform, the high precision measurement is difficult.
变压器的空载试验中,由于功率因数低,空载电流不是正弦信号,高精度测量其有功功率具有一定的难度。
