التحليل المكاني لاستهلاك الطاقة الكهربائية في مدينة الخارجة: دراسة في جغرافية الطاقة باستخدام نظم المعلومات الجغرافية

الملخص EN

The importance of studying electrical energy consumption in al Kharja city is twofold: first, the city relies on a single source of electrical energy, which is Naga Hammadi transformer station; second, it is located so far from the paths of the unified electrical network.

therefore, this research aims at studying the current situation of electrical energy consumption in al Kharja city by identifying the date of electricity entry, studying the components of the electricity transmission and distribution network, studying electrical energy consumption, studying the quantitative development of the number of subscribers, studying the average per capita electricity consumption, and studying the future of electrical energy consumption in the city relying on solar energy, thus aiming at finding a renewable source of electrical energy in the city.

-according to the neighborhood link coefficient factor, the geographical distribution pattern of some components of the electricity distribution network takes a convergent pattern orienting randomly, except the medium voltage lines, that take a dispersed or divergent pattern in distances due to a number of factors, most important of which are: the population, the diversity of economic activities, the transportation network, and the vacant spaces.

-the volume of electrical energy consumption in the city increased highly, as the rate of change in the volume of consumed electricity reached 70.9% from 2010 to 2019, close to five-fold the population increase that reached 14.9% in the same period.

-there is imbalance in the volume of consumed electricity in the various sectors of consumption in the city, whereas the domestic and governmental sectors are 79.9% of the total electricity consumed in the city in 2019; while the amount of electricity consumed in the economic sectors amounted to 10.3% of the total electricity consumed in the same year.

thus, it is necessary to direct electricity consumption in the city to achieve economic development.

-the city is a most suitable place for constructing central solar stations linked to the unified electric grid.

this is due to the fact that the annual average rate of sunshine hours increased by 12.2 hours / day from 1983 to 2019.

this was reflected in the increase in direct solar radiation rates of 26.2 mega joules / m 2 / day in addition to the availability of large areas of uninhabited desert lands.
