three-phase power calculation from voltage, current, and phase angle or power factor ; estimation of other types of power from the given type of power and phase angle or power factor; and finding line quantities and other phase quantities from a phase quantity, one type of power, and phase...
First, select the type of calculation. To calculate the power and load from known voltage and current, select the load connection (star or delta) and enter the voltage (line OR phase), current (line OR phase), and power factor. Click or tap the Calculate button. The power and the load...
The Power Measurement (Three-Phase) block measures the real and reactive power of an element in a three-phase network.
The calculation is shown as follows: (VoltageRise=fracCapacitorKVARxTransformerReactanceTransformerKVA) Legend A Amps V Volts KV Kilovolts (1000 volts) KW Kilowatts (1000 watts) KVA Kilovolt-Ampere KVAR Kilovolt-Ampere-Reactance PF Power Factor C Capacitance (in microfarads)...
Single‐phase loads and photovoltaic generation cause three‐phase imbalance in distribution systems, and prospective growth of normal chargers of electric vehicles may even increase the imbalance. The analysis of such unbalanced systems requires the three‐phase power‐flow calculation. Since existing ...

In the traditional three-phase power flow calculation of the low voltage distribution network, the load model is described as constant power. Since this model cannot reflect the characteristics of actual loads, the result of the traditional calculation is always different from the actual situation. ...
