A multifunctional photovoltaic power generation system independent of utility power line conditions was investigated. The investigated utility interconnected system with cooperate functions each others is available for not only strong utility line but also week line. Summarized results are as next ;1. Operating phase of an interconnected inverter can be controlled by the DC capacitor voltage.2. Power balance among the invertter systems is proportional to the reciprocal of a coupling reactor.3. Instantaneous voltage control at the interconnected point is applicable to the stand alone system.4. The voltage control system is suitable for an active filter to reduce current and voltage harmonics.5. Limiter circuit not to reduce the operating voltage less than the optimum value is important.6. Multilevel inverter with waveform control and inverting operation is useful to noise reduction.7. Hardware MPPT control composed of the discrete IC chips is useful for simplicity of the system.

研究了一种不依赖于电网条件的多功能光伏发电系统。所研究的具有相互协调功能的公用互联系统不仅适用于强公用线路，也适用于弱公用线路。总结结果如下：1.互联逆变器的工作相位可以通过直流电容器电压来控制。2.逆变器系统之间的功率平衡与耦合电抗器的倒数成正比.互联点瞬时电压控制适用于独立系统.电压控制系统适合于有源滤波器，以减少电流和电压谐波.限幅电路的工作电压降低不小于最佳值很重要.多电平逆变器的波形控制和逆变操作是有用的，以降低噪声。采用分立IC芯片构成的硬件MPPT控制有利于系统的简化。
