Interaction influence of harmonics in MIDC transmission systems
Owing to the particular distribution of energy and load, the high-voltage direct current transmission system has been greatly developed in China. A number of areas have formed the multi-infeed direct current (MIDC) transmission systems. In MIDC transmission systems, the electrical distance between t...

Owing to the particular distribution of energy and load, the high-voltage direct current transmission system has been greatly developed in China. A number of areas have formed the multi-infeed direct current (MIDC) transmission systems. In MIDC transmission systems, the electrical distance between the inverter stations is close and the coupling effect is strong, therefore, the interaction influence of harmonics is complex. In order to analyse this complex interaction influence, this study first introduces the influence factors multi-infeed influence factors of power (MIIF-Pd) and multi-infeed total harmonic voltage distortion (MITHDu), which are used to describe the interaction influence degree of harmonics between inverter stations. Then based on the Shanghai power grid, a simulation model of the MIDC transmission systems was built in PSCAD/EMTDC, and the interaction influence degree of harmonics in MIDC transmission systems was studied in the case of large disturbance and small disturbance exists in the inverter stations. The results show that the interaction influence of harmonics between inverter stations is related to the electrical distance, the style of disturbance, transmission power and so on. Meanwhile, the disturbance on a commutation bus mainly leads to the increase of the harmonic distortion rate in this inverter station, and has less influence on the other stations. |
