FAQS about Calculation formulas involved in base station power supply

What is the base voltage of a power company?

If the power company delivery voltage is 13.2kV, the base voltage will likely be 13.2kV unless otherwise noted. Voltages are always line-line or phase-phase voltage. Base MVA or Base kVA: A widely used base is 100MVA. But it is possible to select any other base if the operator chooses so. 1MVA=1000kVA.

Can a PU value be converted back to a voltage?

A PU value can readily be converted back to a voltage, power, or any other value as long as the base value is known. Although the PU system could most likely be used for systems other than electrical systems, it is probably used mostly with electrical values. The PU system deals primarily with values of power, voltage, current, and impedance.

What does Pu stand for in electrical power systems analysis?

The article explains the Per Unit (PU) system used in electrical power systems analysis, focusing on how it simplifies calculations by expressing electrical quantities as ratios to base values.

What parameters are normalized before a power system analysis?

Power system parameters, such as voltage, current, and impedance, are often normalized to a base power and voltage before analysis. This simplifies the analysis of the power flow in the system. For example, for a transformer, you can ignore turns ratios of transformers. The units generally used in power systems studies are built into Maple.

What is analysis of a three-phase power system?

Analysis of a three-phase power system is a process that analyzes the power flows on a per unit basis. Power system parameters (such as voltage, current and impedance) are often normalized to a base power and voltage before the analysis.

What is a PU system of calculations?

More specifically, the per unit method of calculation is often used in the calculation of short circuit currents. The PU system of calculations was more prevalent in the past years. However, the availability of computer programs for system analysis has diminished to some extent the need for the PU system of calculations.
