اندازه گیری و مدل سازی انتشار سیگنال کنترل رطوبت از طریق شبکه توزیع

The paper deals with the estimation of the vertical propagation of the Ripple Control Signal (RCS) through the distribution network segment. Magnitude of the RC signal is determined at various points in the network using in-situ selective pulse measurements as well as simplified model of the distribution network based on the antenna theory. Measurements are carried out in the 3-phase system on 3 voltage levels, 110 kV, 10 kV and 400/230 V, respectively, in either indirect or direct configuration, depending on nominal voltage. Distribution network segment is modeled as an antenna excited with voltage source on one end and terminated with corresponding impedance on the other. The current induced along the distribution cable is determined by solving the corresponding Pocklington integro-differential equation in the frequency domain. The numerical solution is undertaken via Galerkin–Bubnov scheme of the Indirect Boundary Element Method (GB-IBEM). Results obtained via different methods seem to agree satisfactorily.
