请问TI例程里定义的这些标幺值(pu),它的基准值在哪啊?

Other Parts Discussed in Thread: CONTROLSUITE

标幺值=实际值/基准值,基准值在程序里没找到,那怎么确定它的实际值呢?

  • 一般在头文件,例如HVPM_Enhanced_Sensorless-Settings.h

    C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.1\HVPM_Enhanced_Sensorless_2803x

    // Define the electrical motor parametes (Estun Servomotor)
    #define RS 2.35 // Stator resistance (ohm)
    #define RR // Rotor resistance (ohm)
    #define LS 0.0065 // Stator inductance (H)
    #define LR // Rotor inductance (H)
    #define LM // Magnatizing inductance (H)
    #define POLES 8 // Number of poles

    // Define the base quantites
    #define BASE_VOLTAGE 236.14 // Base peak phase voltage (volt), Vdc/sqrt(3)
    #define BASE_CURRENT 10 // Base peak phase current (amp), Max. measurable peak curr.
    #define BASE_TORQUE // Base torque (N.m)
    #define BASE_FLUX // Base flux linkage (volt.sec/rad)
    #define BASE_FREQ 200 // Base electrical frequency (Hz)

    #endif
