| 1 | Modelling, parameter estimation and assessment of partial shading conditions of photovoltaic modules显示文摘This paper proposes a method for assessing the effect that different features of partial shading conditions(PSC) may have on the operation of a photovoltaic(PV)system.Simulation studies, based on an experimentally validated model of a PV system, are used to assess the influence of PSC.Three classifications of PSC are defined based on the timescale of their influence on the irradiance experienced by the PV module and the relative location of the voltage at which the global maximum power point occurs is assessed.Sample case studies are presented to illustrate the application of the proposed PSC assessment method.The results have implications for the design of future maximum power point tracking methods. | S.LYDEN M.E.HAQUE | 2019 | Journal of Modern Power Systems and Clean Energy2019，7，1： | 2 |
| 2 | VARIATION OF PHYSICO-CHEMICAL PROPERTIES OF RADIATION CROSSLINKED RUBBER WITH STORAGE TIME显示文摘The effect of storage on physico-chemical properties of non-irradiated natural rubber and radiation vulcanized natural rubber (RVNR) were evaluated. The rubber films were stored under two different conditions, namely in open air and sealed polyethylene bags. The antioxidant, tris(nonylated phenyl) phosphite (TNPP) was used for preventing degradation of RVNR films. Gel content, cross-link density, tensile strength at break and 500% elongation of rubber films were measured.The results show that the retention (%) of tensile properties of rubber films with TNPP is higher than that of rubber films without antioxidants. The rubber films stored in polyethylene bags also show better retention of tensile properties than those of rubber films stored in open air. | N.C.Dafader M.E.Haque F.Akhtar | 2005 | Chinese Journal of Polymer Science2005，23，5： | 0 |
| 3 | ROLE OF SYNTHETIC ANTIOXIDANTS ON THE AGING PROPERTY OF ELECTRON BEAM IRRADIATED NATURAL RUBBER显示文摘The aging property of radiation vulcanized natural rubber was studied using various kinds of antioxidants. Aging test was done at 100℃ for various lengths of time. It was found that some antioxidants are excellent in preventing the oxidative degradation of the irradiated rubber. DAH (2,5-di-tert-amylhydroquinone) + CBP (2,2'-dihydroxy-3,3'-di(-methylcyclohexyl)-5,5'-dimethyl diphenyl methane) + P16 (tris(2,4-di-tert-butylphenyl)phosphate) in a proportion of (1:0.5:0.5)was found to be the best combination to achieve 100% retention of tensile strength. | M.E.Haque K.Makuuchi F.Yoshii H.Mitomo | 2005 | Chinese Journal of Polymer Science2005，23，4： | 0 |
