Abstract

110 kV modular substation adopts a modular construction approach

featuring standardization

factory prefabrication and intensive design

making it the preferred construction model for smart substations.110 kV modular substation in operation is affected by the difference of climate environment in different regions

and the problem of heat accumulation and condensation of electrical equipment is existed

which affect seriously both life

safe and stable operation of the electrical equipment. In this paper

the heat generation characteristics of 110-A2-6 modular substations and their electrical equipment in Jiangsu province are taken as the research subject. The heat generation characteristics of such main electrical equipment as transformers

capacitors

switchgear

GIS are modelled and analyzed

and the heat generation patterns of the electrical equipment in modular substations are obtained. Finally

the method of placing loop control sensors is introduced in the 110 kV modular substation

and the measured data is matched with the heat generation model

thus providing a reference basis for the improvement of the heat and humidity environment in the modular substation.
