The satisfaction of the energy needs of a computer laboratory requieres a systematic study of the consumption of the various electrical receivers listed. A compromise must be found between the time of use of these receivers and the number of needed to be connected to the photovoltaic power source in order to minimize, as much as possible, the daily energy consumed by the installation. We note the peak power (P_c), the number of the panels (N_(pa,t)), the power of the inverter (P_Ond) and the current of the regulator (I_rég) are lineary a function of the daily energy (E_cj). The total number of batteries (N_(b,t)) is a linear function of the daily energy (E_cj) and the autonomy of the battery bank (N_Au).
In this paper, we propose a simplified and reliable method for sizing, selecting and wiring of the photovoltaic components in order to ensure an effective and secure supply of electrical energy.
The electrical energy supplied to industrial consists of an active (userful) part used to transform electrical energy into another form of energy (mechanical, thermal, …) and a reactive part necessary for magnetic and capacitve uses. The main concern here is to produce reactive energy in the industrial plant of Congo-Oil company in order to minimize the power passed through the pipes and the load rate of the electrical power supply (transformer). This article proposes a reliable mathematical method to be used to compensate reactive electrical energy in an industrial enterprise with bad power factor. We find that the demand power (S) and the load ratio (Tx) àf the transformer are inversely proportional to the power factor. Also, the reactive energy (Qc) to be produced tends towards zero when the power factor progressively tens towards the unit. This method compensation allowed us to reduce the apparent power and the transformer load rate by approximately thirteen percent. (≈13%).
