Abstract

The increasing applications of CVTs can cause significant error in the harmonic voltage measurement. The correct measurement of the frequency response and the accurate parameter estimation are two main components for the calibration of CVTs. This paper establishes an experimental platform for the measurement of the frequency response of high voltage and medium voltage oil-immersed CVTs. Because the parameters of the oil-immersed CVTs are consistent, a key parameter optimal estimation model is developed based on the comparison of the measurement and simulation. A simplified equivalent circuit model is taken as the simulation model. The estimation results show that the optimal model brings more accurate parameters and reduces the experimental workload.
