Thus, the power transfer is doubled by 50 % compensation. Improvement in System Stability – For same power transfer and for the same value of sending and receiving end voltage, the phase angle δ in the case of the series impedance line is less that for the uncompensated line.The reduced value of δ gives higher stability. Load Division among Parallel Line – Series …

In Figure 4, the power transfer, P, is shown as a function of angular displacement, c, for two cases: with no compensation, and with series compensation. At a certain moment, a fault occurs in the system, during which the transmitted electrical power P becomes zero, while the mechanical input power to the generator remains constant, Pm.
The following four cases of reactive power compensation are considered and discussed: adequate, conditionally adequate and total compensation, as well as overcompensation.
The current-unbalance mechanism is illustrated and a current-sharing compensation method for IPT coils is proposed, where a compensation capacitor with a specially designed value is connected in each branch so that the current unbalance can be suppressed by the increased branch impedance. Expand

Further as load 2 turns on, capacitor bank 2 also turns on along with 1 to provide compensate the dip in the power factor. Therefore, when both the loads are switched in the circuit, all the capacitor banks are active thus providing full compensation to the system and correcting the power factor to 1.

3.1 Analysis of fault characteristics under active operation. Open circuit faults can be separated into three categories. Case I, Case II, and Case III denote a failure in T 1, a failure in T 2, and simultaneous failures in T 1 and T 2, respectively.The fault features are shown in Table I where U smi, V cap_i, and S i represent the output voltage, the voltage of the …
A current‐sharing compensation method is proposed in [13] to balance the current in the DWP coil, but the complete compensation method equivalent to the traditional compen-sation method is not proposed. In this work, the reason for the unbalanced current stress of the DWP coil in the conventional compensation method in the WPT is investigated.
Both techniques adopt two compensation capacitors, which exploit the Miller effect, to split low-frequency poles and to achieve the desired phase margin and transient response. ... where ϕ B is in Table 2 (equal to the DACFC second case) and the Miller compensation capacitor is reported in Table 1. 4.5 CBMCPC and CLIA topologies. Although ...
