Optimising the thermal environment and the ampacity of underground power cables using the gravitational search algorithm
(The Institution of Engineering and Technology, 2018-01)
This study takes into consideration a problem that commonly occurs at the design stage of underground cable lines and that relates to the manner of determining the optimal values for dimensions of cable trench and bedding, ...
Controlling the thermal environment of underground cable lines using the pavement surface radiation properties
(IET Generation, Transmission & Distribution, 2018-05-03)
The main purpose of this study is to show how the emissivity and absorptivity of a pavement surface aboveunderground cables affect their ampacity. The use of cool pavements whose surfaces absorb less heat ...
THE EFFECT OF DIFFERENT SKY TEMPERATURE MODELS ON THE ACCURACY IN THE ESTIMATION OF THE PERFORMANCE OF A PHOTOVOLTAIC MODULE
(Technical University of Gabrovo, 2019-11-22)
This paper considers the effect of different sky temperature models on the accuracy in the estimation of the performance of an open-rack-mounted photovoltaic (PV) module. It is found that, for the same ambient conditions, ...
Thermal aging management for electricity distribution networks: FEM-based qualification of underground power cables
(Thermal Science, 2022-03)
It is well-known that there is no PLAN-DO-CHECK-ACT (PDCA) approach that is used by electricity distribution network operators and asset managers of power cable systems. Accordingly, this paper proposes a novel application ...
Eliminating the effect of hot spots on underground power cables using cool pavements
(Electrical Engineering, 2019-10-24)
It is well known that hot spots limit the ampacities of underground power cables. There are many commonly applied methods
to control the thermal environment in hot spots of underground power cables. However, applications ...
A thermal model for open-rack mounted photovoltaic modules based on empirical correlations for natural and forced convection
(Thermal Science, 2019-01-12)
This paper proposes a thermal model for calculating the temperature of open-rack mounted photovoltaic (PV) modules taking into account the meteorological conditions, position (i. e. the inclination of one PV module and the ...
GA-based approach for optimal placement and sizing of passive power filters to reduce harmonics in distorted radial distribution systems
(Electrical Engineering, 2019-09)
This paper presents a Genetic Algorithm-based approach for optimal placement and sizing of passive power filters to mitigate harmonics in radial distribution systems with linear and nonlinear loads. The problem is formulated ...
Modelling the thermal effect of solar radiation on the ampacity of a low voltage underground cable
(International Journal of Thermal Sciences, 2018-08)
Compared with other underground cables, low voltage cables are most intensely heated by the sun due to the low laying depth. Accordingly, the main purpose of this paper is to show how the heat of solar radiation affects ...
A transient thermal model for flat-plate photovoltaic systems and its experimental validation
(ELEKTRONIKA IR ELEKTROTECHNIKA, 2019-04)
This paper describes a transient thermal model that accurately predicts the temperature of the open-rack mounted photovoltaic (PV) modules under varying atmospheric conditions. The PV module temperature is predicted by ...
