This paper introduces a novel tangential radial hybrid excitation synchronous generator (or T/R-HESG, for short). Firstly, the author deeply analyses its magnetic path model, completes the design and gives some improved methods with the assistance of Ansoft Maxwell 14 software. Then the author developed two models of T/R-HESG, but only one, a 380V/1.5KVA prototype, has been fabricated and its corresponding...
Global solar radiation is need knowledge for solar energy system design. In this work, the artificial neural networks (ANN) were applied to estimate the daily global solar radiation in China. Eight-year meteorological data from ten weather stations, which located at very different locations and climate zone, was randomly split into training, validation and test set with the proportion of 2:1:1. Daily...
Solar radiation knowledge is important for the solar energy conversion and utilization. In this work, least squares-support vector machine (LS-SVM) algorithms were applied to estimate the yearly and monthly average daily global solar radiation in China using the ordinary meteorological data and geographic parameters. The monthly climatic data from 101 radiation measurement stations were divided into...
