中文摘要：
首先论述基于公共节点电压的逆变器并联功率理论的局限性，从新的角度推导基于逆变器输出端电压的并联功率理论。通过线性组合定义“类功率”变量，类有功功率和类无功功率分别只与相位差和幅值差有关，从而提出无互联线并联“类功率”下垂控制策略。推导新型控制策略下的并联系统小信号数学模型，为并联系统的性能分析和参数设计提供理论依据。在2台三相逆变器并联平台上进行实验研究，仿真和实验均表明并联系统具有良好的均流效果。
英文摘要：
This paper analyzed the limitation of traditional power theory of parallel operation of inverters based on the voltage of point of common coupling （PCC）. An improved power theory of parallel system was deduced based on output terminal voltage of an inverter from a viewpoint of micro-grid autonomy operation. The ＂quasi power＂ variables were defined by linear combination and quasi active power and quasi reactive power were only related to the phase and amplitude difference respectively. A quasi-power droop control method for parallel connected inverters was proposed based on the improved power theory. The small-signal mathematical model of the parallel system was derived in a novel droop control scheme, which provided a theoretical basis for the parallel system performance analysis and droop coefficient design. The experiments and simulation were studied in the platform formed by two parallel connected three-phase inverters. The experimental results show that the proposed control strategy is feasible and the good sharing current effect is obtained.
