“…Underground cables have an increased capacitance compared to overhead lines. The resonance frequencies of the power system may therefore be reduced which leads to overvoltages and consequently to the overheating of components such as transformers due to the resulting harmonic currents [6]- [8]. This The number of grid connected power electronic converters is increasing due to both HVDC lines and renewable energy sources.…”

Medium to long-distance underground AC lines and both short-and long-distance HVDC are frequently integrated into network expansion plans. In conjunction with growing numbers of power electronic converters in the grid there is a rising risk related to the effects of harmonic currents. Resonance analysis should therefore be part of power system expansion planning. In this paper, network harmonic modeling and analysis are discussed, in particular power transformer and power converter frequency models are proposed. Frequency scanning and resonance mode analysis are compared and discussed. The changes in resonance response due to transmission network expansion are drawn. The methods are applied to the investigation of the impact of one link reinforcement, both AC and DC solutions, as well as the impact of the power transformer disconnection. The performed analysis allows to find the resonance location at each studied case. The frequency analysis methods presented in this paper enables to foresee network frequency behavior that is valuable for both network analysis and network expansion planning.

“…It is also concluded that the switching operations of any series or shunt power system component may dramatically influence the system resonance. Harmonic issues associated with a long underground cable in the transmission system are discussed in [9]. In [10] subsea power cables are considered.…”

Presently there is a great interest in underground cable transmission lines in extra high and high voltage level networks. The undergrounding of the transmission system can lead to the decrease of the resonance frequencies resulting in high overvoltages and possible power system component damages. It is therefore necessary to analyze possible resonance problems in the mixed power transmission system. In this work a frequency dependent model for transmission systems is implemented and the frequency scan results are presented. In order to gain a better understanding of the nature and extent of the resonance, a resonance mode analysis is also executed. The proposed procedure is tested on two examples: a ten-node power system and the Swiss extra high voltage (EHV) power transmission system. Power systems comprising solely overhead lines and different variations of mixed power system are examined.

“…However, detailed layouts and field data measurements better reflect the cable models [14]. Low order (lumped) impedance models can be considered with high accuracy for some studies, such as current control assessment [14], [18]. However, distributed models are more accurate when studying harmonics over a wider frequency range [12], [18].…”

Abstract-This work reviews the state-of-the-art in the field of harmonic resonance problems in Wind Power Plants (WPPs). Firstly, a generic WPP is modeled according to the equivalent circuits of its passive and active components. Main focus is put on modeling active components, i.e. the ones based on power converters. Subsequently, pros and cons of frequency and time domain analysis methods are outlined. The next sections are devoted to mitigation methods implemented in the power electronics converters. From the wind turbine perspective, different techniques to enhance the robustness of the controller are analyzed. Subsequently, the suitability for active damping of harmonics using STATCOM devices is assessed, with focus both on control techniques and power converter technologies.
