Embodiment Construction
[0052]The actual process of the electromagnetic transient numerical calculation method based on the 3-step 4-order implicit Taylor series method proposed by the present invention is basically the same as that of the traditional electromagnetic transient numerical calculation method. The difference is mainly the numerical integration in step 4 The scoring methods used are different.
[0053] by Figure 4 The shown single-phase power frequency uniform long transmission line is an example of the electromagnetic transient simulation calculation of no-load closing under different initial phase angles. The specific implementation steps of the present invention are summarized as follows:
[0054] 1): Input the initialization data, establish the differential equations of each component of the system, and form the basic mathematical model of electromagnetic transient numerical calculation:
[0055] well known, used to describe Figure 4 The mathematical model of the electromagnetic t...
