基于开关平均模型进行 PID 调试 将上图中的开关网络用 “Average-Model Based VSC” 替代 —— Simscape Electrical 中的 “Universal Bridge” 中选择这个类型即可。这样就是一个开关平均模型。 然后在双击 PID 模块,选择 Tune。 这一步会打开 PID tuner。在此之后,需要找一个稳态工作点来线性化被控...
Change Model 1 to represent the Ideal Switch, and then run the model to compare the "Switching-function based VSC" and the "Average-model based VSC." You can view the outputs by double-clicking the green Scope. Model 1 is displayed in yellow, Switching-function approximation in blue, and...
当你选择切换功能的VSC(变压设备),开关功能的电压源整流器型等效模型,其中开关是由两个交流侧电压源和直流源的电流代替的。该模型使用与其他电力电子设备相同的发射脉冲,它正确地反映正常产生的电桥谐波。 When you select Average-model based VSC, an average-model type of voltage source converter is used to ...
The average model (discrete) - The model in this example. In this type of model the IGBT Voltage-sourced converters (VSC) are represented by equivalent voltage sources generating the AC voltage averaged over one cycle of the switching frequency. A similar method is used f...
Diodes (default) | Thyristors | GTO / Diodes | MOSFET / Diodes | IGBT / Diodes | Ideal Switches | Switching-function based VSC | Average-model based VSC Ron (Ohms)— Internal resistance 1e-3 (default) Lon (H)— Internal inductance 0 (default) Forward voltages [ Device Vf(V) , Diode...
When you select Average-model based VSC, an average-model type of voltage source converter is used to represent the power-electronic switches. Unlike the other power electronic devices, this model uses the reference signals (uref) r 16、epresenting the average voltages generated at the ABC ...
Open the VSC Controller subsystem to see the details. The sample time of the controller model (Ts_Control) is 74.06 µs, which is ten times the simulation sample time. The later is chosen to be one hundredth of the PWM carrier period (i.e., 0.01/1350 s) giving an acceptable simulati...
