By use of time-varying Fourier coefficient series of power system variables, new dynamic phasor models of thyristor-controlled reactor are developed. In this model the higher order harmonic components that have less impacts on dynamic characteristic of TCR are neglected, and through the average operation of time-domain model of TCR, a dynamic phasor state-space model of TCR is derived.

The results show that whether the stiffness profiles are smoothly varying or layered, the fundamental mode dominates the surface wave field and the effective phase velocity approaches to the phase velocity of the mode in far field for the regular profiles. For the irregular profiles, the higher modes have a significant influence on the surface wave field. The intensity and the frequency range of the influence are related to variation of the profile stiffness.
结果显示,无论剖面刚度是缓变还是分层变化,对规则剖面,表面波场基阶模态占主导地位,远场表面波有效相速度与基阶模态相速度接近;对不规则剖面,表面波场中高阶模态影响较大,影响程度及频率范围与剖面刚度变化有关。
