本文讨论了补偿性能的恒定直流电容电压控制（CDCVC）为基础的智能充电器的策略与先前提出的无功功率控制算法在单相三线配电馈线（SPTWDF）在电源电压失真的条件下。详细讨论了瞬时功率流入智能充电器的问题。流入智能充电器的瞬时功率表明，基于CDCVC的策略与先前提出的无功功率控制算法实现了平衡，并且实现了功率因数为0.9的正弦电源电流，该功率因数为0.9，这是预定义的值。因此，先前提出的无功功率控制算法与CDCVC是适用于失真的电源电压条件下。通过计算机仿真验证了在电源电压畸变情况下，本文提出的基于CDCVC的无功控制算法的有效性和实用性。仿真结果表明，正弦和平衡的电源电流的功率因数为0.9，这是一个预定义的和可接受的值由日本法规，实现在SPTWDF的电源电压失真的条件下。
This paper addresses compensation performance of the constant dc-capacitor voltage-control (CDCVC)-based strategy for smart charger with the previously proposed reactive power control algorithm in single-phase three-wire distribution feeders (SPTWDFs) under distorted source voltage conditions. The instantaneous power flows into the smart charger is discussed in detail. This instantaneous power flowing into the smart charger shows that the CDCVC-based strategy with the previously proposed reactive power control algorithm achieves balanced and sinusoidal source currents with a power factor of 0.9, which is a predefined value, are achieved. Thus, the previously proposed reactive power control algorithm with the CDCVC is applicable under distorted source voltage conditions. A computer simulation is implemented to confirm the validity and practicability of the previously proposed reactive power control algorithm with the CDCVC under distorted source voltage conditions. Simulation results demonstrate that sinusoidal and balanced source currents with a power factor of 0.9, which is a predefined and acceptable value by Japanese regulations, are achieved in SPTWDFs under the distorted source voltage conditions.
