Electrical Model of Line 0.4 kV for Research Compensation of Reactive Power
Abstract
In Russia, it is believed that the compensation of reactive power in low voltage networks is impractical due to the low transmit power and the absence of reactive power consumers. In addition, in most such networks there is no information about power flows and voltage values, which complicates the task of effective compensation of reactive power. To study the compensation of reactive power in 0.4 kV networks, a model electric circuit for replacing the 0.4 kV line was developed and created. The model line contains a three-phase step-down transformer (TZSI-1.6 VA, 380/42), variable resistors and inductors are used as loads, and electric capacitors are used as capacitor batteries. All parameters of the model are the power of resistors and inductors, the voltage values are proportional to the actual parameters of the 0.4 kV line. The created model line most fully reflects the processes of power flows, voltage losses and power in the line phases, the change in power factor with the changing nature of the loads.
