“…Taking phase A of the transformer as an example, the primary harmonic currents are derived below. Equations (15) I A1k and I A2k are the harmonics produced by one converter transformer individually. For the total harmonics in the power grid, we need to add up the same order primary harmonics produced by two converter transformers, =…”

“…The grid current is decomposed into the sum of some simple functions. Each simple function harmonics can be calculated separately, which is analogous to the Laplace operator method [14,15]. By applying this approach, this paper presents a piecewise method to calculate the characteristic harmonics in three different operation modes of the PF converter.…”

Poloidal field (PF) converters provide controlled DC voltage and current to PF coils. The many harmonics generated by the PF converter flow into the power grid and seriously affect power systems and electric equipment. Due to the complexity of the system, the traditional integral operation in Fourier analysis is complicated and inaccurate. This paper presents a piecewise method to calculate the harmonics of the ITER PF converter. The relationship between the grid input current and the DC output current of the ITER PF converter is deduced. The grid current is decomposed into the sum of some simple functions. By calculating simple function harmonics based on the piecewise method, the harmonics of the PF converter under different operation modes are obtained. In order to examine the validity of the method, a simulation model is established based on Matlab/ Simulink and a relevant experiment is implemented in the ITER PF integration test platform. Comparative results are given. The calculated results are found to be consistent with simulation and experiment. The piecewise method is proved correct and valid for calculating the system harmonics.
