Regarding the issue of power consumption

I hope experienced colleagues can offer some guidance. Our company’s estimated electricity consumption is 2150; what other data is needed to calculate it? What is the relationship between power consumption and current, voltage, as well as the voltage per cell? # ， ， &
The AC power consumption is: actual alkali production / actual AC power used. As the current increases, power consumption and cell voltage also rise accordingly. Theoretical power consumption: Cell voltage/(Cell voltage*1.492)
Theoretical power consumption: cell voltage / (cell voltage * 1.492), is that correct? I remember it as: Theoretical power consumption = (Theoretical decomposition voltage / 1.492) × 1000, Actual power consumption = Actual cell voltage / (1.492 × current efficiency) × 1000
Actual power consumption = Total AC power consumed / Alkali production volume
There are specific accounting procedures that outline how to calculate power consumption
Theoretical power consumption = Actual cell voltage / (1.492 × current efficiency) × 1000. Actual AC power consumption = AC electricity consumption for the month / Actual caustic soda production for the month
1. The calculation formula for AC power consumption is included in the above responses. However, statistics may be classified into two types: one is to calculate the alkali production by counting the alkali delivered from the alkali concentrate tank, and the other is to calculate the alkali production by deducting the alkali used internally and the lost alkali from the total amount of alkali. Usually the latter one on the report. 2. The relationship between power consumption and current is relatively complex, and it is likely to be similar to a parabola. With all other conditions unchanged, at a fixed current, the higher the current, the lower the power consumption; beyond a certain threshold, however, the higher the current, the higher the power consumption. 3. Under normal production conditions, for the same system, with constant current, the higher the voltage, the greater the power consumption. The level of voltage depends on the resistance of the cell; the greater the resistance, the more unnecessary energy is consumed. A change in current level significantly affects the cell voltage; with constant resistance, if the operating current increases, the voltage must also increase, and it is at this point that the critical current comes into play. 4. The single-cell voltage mainly reflects the operating condition of the cell, and has little impact on the overall power consumption. Generally, the lower the voltage of a single slot, the better its operating condition. The above are merely personal opinions.
