“…Although its simplicity and ease to implement the control this solution provides very poor attenuation of current ripples. To ensure good attenuation of these ripples and, at the same time, low attenuation of harmonics within the APF compensation bandwidth it is necessary to apply 3 rd order LCL connecting circuit [1].…”

The paper presents the concept of 2 MVA, medium voltage active power filtering system. The system is modular, thus provides full scalability. All the power modules of the system share a special, unified topology of 3 rd order LCL passive circuit, which together with predictive control provides very high filtering effectiveness and, at the same time, zero current ripples. This paper contains preliminary simulations. The full power, MV system is currently being applied.

Grid-connected inverters require a third-order LCL filter to meet standards such as the IEEE Std. 519-1992 while being compact and cost-effective. LCL filter introduces resonance, which needs to be damped through active or passive methods. Passive damping schemes have less control complexity and are more reliable. This study explores the splitcapacitor resistive-inductive (SC-RL) passive damping scheme. The SC-RL damped LCL filter is modelled using state space approach. Using this model, the power loss and damping are analysed. Based on the analysis, the SC-RL scheme is shown to have lower losses than other simpler passive damping methods. This makes the SC-RL scheme suitable for high power applications. A method for component selection that minimises the power loss in the damping resistors while keeping the system well damped is proposed. The design selection takes into account the influence of switching frequency, resonance frequency and the choice of inductance and capacitance values of the filter on the damping component selection. The use of normalised parameters makes it suitable for a wide range of design applications. Analytical results show the losses and quality factor to be in the range of 0.05-0.1% and 2.0-2.5, respectively, which are validated experimentally.
