Research the distortion of applying CVT to measure harmonic in the high-voltage power network
Simulation of the CVTs harmonic measurement distortion, and analyze the sensitivity of the main components parameters use of the steady-state circuit were conducted in the thesis. The transformation ratio characteristics have been simulated by using the high-frequency equivalent circuit, and the relationgship between the main stray capacitances change and the change of CVTs pass band have been analyzed. At the same time, combining the engineering application, we propose to make use of the combination of experimental data with artificial neural network to correct the CVTs transformation ratio. This method can be used to monitor harmonic chronically through the CVT. Testified by emulators, this method is feasible.
