本文利用径向基函数（RBF）网络建立了电容直流平滑非控制整流桥的稳态频域模型。将非线性负荷模型引入平衡谐波潮流程序中，以评估该装置给电网带来的谐波畸变。在谐波潮流算法中，将非线性负载的有功和无功灵敏度纳入雅可比矩阵，从而增强了基频潮流。利用RBF网络建立的非线性负荷模型可以很容易地计算出这些灵敏度。
In this paper, a steady-state frequency-domain model of an uncontrolled rectifier bridge with capacitive dc smoothing, developed with radial basis function (RBF) networks, is presented. The nonlinear load model is incorporated in a balanced harmonic load-flow program in order to evaluate the harmonic distortion introduced in the networks by this device. The fundamental frequency load flow, used in the harmonic load-flow algorithm, is enhanced with the incorporation to the Jacobian matrix of active and reactive power sensitivities from nonlinear loads. These sensitivities can be computed easily from the nonlinear load model built with RBF networks.
