Research on Integrated Circuit inElectronic Capacitive Voltage Transformer
摘要
Abstract
For amplitude and phase of the integration circuit in electronic voltage transformer based on capacitance division susceptible to frequency conversion in power system,using a program which combined passive integrator circuit and active integrator circuit together in the integration circuit,passive integrator circuit performs high-band signal processing and active integrator circuit to complete the low-band signal analysis,then compared with the simulation results of composite circuit.Experiments show that,through rational design parameters of the active and passive integrator circuit,it is possible to realize the coordination of the intersection of frequency magnitude and phase angle,and waveform measurement error can be reduced.关键词
