变压器磁滞设计工具

可饱和变压器块的可饱和核心的查看和编辑磁滞特征

Description

磁滞设计师app allows you to view and edit a hysteresis characteristic for the saturable core of the多方面变压器,,,,Saturable Transformer,,,,三相变压器(两个绕组),,,,andThree-Phase Transformer (Three Windings)块。磁滞特征包括位于磁滞回路极限的饱和区域。

A default hysteresis characteristic displays when you open the app, but you can build as many hysteresis characteristics as you want and save them in different MAT-files. You can use the same characteristic for all your transformer blocks, or you can use different characteristics for each transformer block in the circuit. In the mask of a transformer block, selectSimulate hysteresisand specify a MAT-file to use.

磁滞设计师app includes a flux animation tool that can visualize how bySIMSCAPE™Electrical™专门的电力系统软件执行磁滞的模拟。这是模型参数化不需要的可选工具。该应用根据定义的滞后特征计算初始轨迹。该工具假设启动通量之前的最后一个反转点位于主要循环上。操作点会传播,直到定义的停止通量为止。

参数

滞后参数

转换定义滞后特性的通量和电流sipuor frompusi

用于定义滞后环的右侧的线性段数量。环的左侧是右侧的对称图像。

Remnant flux point of the hysteresis characteristic (flux at zero current). The remnant flux point is identified by a + mark in the plot.

Coercive current point of the hysteresis characteristic.

Slope of the flux at the coercive current point (current at zero flux).

饱和磁滞回路成为单值饱和曲线的饱和通量点。饱和通量点通过图中的一个 *标记识别。

滞后循环成为单值饱和曲线的饱和电流点。饱和区域由饱和区域电流范围。

Nominal parameters (nominal power in VA, nominal voltage of winding 1 in volts RMS, and nominal frequency in Hz) used in the conversion of the hysteresis parameters.

定义饱和特性的电流值的向量。指定点的数量必须与饱和区域通量范围。您只需要指定特征的积极部分。

该参数主要用于最大程度地减少多余的,非常小的内部环或新轨迹的生成,因为它们的效果很小,并且消耗了计算机存储空间。该模型可以随时记住多达50个嵌入式小环。

tol_f参数是用于检测wh公差值ether, after a flux reversal, the operating point remains on the same minor loop or a new embedded loop is created. The smaller the value, the lesser the effect on the normal trajectory behavior. The bigger the value, the lesser the generated number of embedded minor loops.

Finally, when the distance between the I coordinate of the actual point of reversal and the penultimate one is less thantol_i,然后在这两个点内的演变遵循线段而不是循环。
