For the LCL-type grid-connected inverter, grid voltage full feedforward scheme is an effective method to improve the quality of the injected grid current. However, in the applications where a step-up transformer is adopted and its leakage inductance serves as the grid-side inductor, it is difficult to directly measure the grid voltage.

6 FAQs about [Capacitor local compensation scheme]
What is a compact capacitive compensation scheme?
In this article, a compact capacitive compensation scheme using a minimal number of compensation capacitors is proposed to realize series/series–parallel (S/SP) compensation for adjustable CV output and series/parallel–series (S/PS) compensation for adjustable CC output, achieving reduced system weight, volume, and cost.
What is fault location in series capacitor compensated three terminal transmission lines?
Fault location in series capacitor compensated three terminal transmission lines based on the analysis of voltage and current phasor equations and asynchronous data transfer Accurate fault location algorithm for shunt compensated double circuit transmission lines using single-end data
What is the output voltage of s/PS compensation?
The output voltage of the S/SP compensation or the output current of the S/PS compensation is independent of the load and the IPT transformer parameters, making the system design straightforward.
What is the protection system of series capacitor bank?
Protection system of series capacitor bank. Where, i MOV is the MOV current, v x is the MOV voltage, V max is the maximum permissible capacitor voltage, p and α are characterizing constants. p is the current that flows through the MOV when V max is applied across it.
What is the resistance of a compensating capacitor?
For the proposed scheme the compensating capacitor is varied from 0.5 to 7.5 PF (continuous curves). For the circuit using ESR, the resistance is varied in the range of 0.1—2.5 (dashed curves); the results are shown in Fig. 12. For small ESR values, some parasitic oscillations are present due to the limited phase margin.
How does a capacitor reduce the frequency of an error amplifier?
The capacitor added to generate the zero also reduces the frequency of the pole at the output of the error amplifier. The proposed method starts with the addition of a pole—zero pair as in [1 Il and proceeds toward eliminating the pole from the pole—zero pair.
