Modeling of phase detector for reactive power regulator
The task of developing a compensator of reactive power for residential consumers of electricity is solved by application of the analog circuit of the transmitter. The first stage of calculation capacity balancing capacitors is to determine the phase difference of voltage and current consumption. Circuit implementation phase detector most simple method based on transforming an interval of time in voltage. Consider three schemes of detectors: -phase detector on limiters; -phase meter on comparators with transistor keys; -phase meter on comparators with D - trigger. Circuit simulation with service Electronics Workbench was made at various values of input voltage in the range ∆φ from 0 to 100 angular degrees. Analysis of results of modeling allowed us to highlight the scheme of phase meter on comparators with transistor keys. This scheme has a maximum sensitivity and linear directly proportionate the dependence of the output voltage from the phase difference of the input signals.
