项目摘要

A topology of the interconnected hybrid generating system with photovoltaic cells and a wind turbine to the AC power grid has been investigated in this research. We have first discussed the interconnected wind generating system. DC Motor simulating the wind turbine drives the Permanent Magnet Synchronous Generator. The generating AC power should be converted to the DC by diode rectifier, and then be interconnected to the AC power grid through the three-phase current source inverter. By adjusting only the modulation factor in the inverter appropriately, the maximum power in each wind velocity can output to the grid regardless of the wind fluctuation.Next, the solar generating system has been discussed so that plural PV panels under the different solar irradiances can output the respective maximum powers. The cascaded boost choppers are connected to such two PV panels. It has been made clear by several experiments that the proposed system can carry out the above purpose.Finally, in order to combine properly the both PV and wind generating voltages, the DC-DC converter applied with the series-parallel chopper is employed. Even if the solar irradiance and the wind velocity are fluctuated violently, the inverter circuit can be operated stably, and the respective maximum output powers can be supplied to the grid by controlling the duty factor in the converter and the modulation factor in the inverter.

本研究研究了具有光伏电池和风力涡轮机与交流电网的互连混合发电系统的拓扑。我们首先讨论了互联风力发电系统。模拟风力发电机的直流电机驱动永磁同步发电机。产生的交流电需通过二极管整流器变换为直流电，然后通过三相电流源逆变器并入交流电网。只需适当调整逆变器中的调制系数，无论风力波动如何，每种风速下的最大功率都可以输出到电网。接下来，讨论了太阳能发电系统，使得多个光伏板在不同太阳辐照度下可以输出各自的最大功率。级联升压斩波器连接到这样的两个光伏电池板。通过多次实验表明，所提出的系统可以实现上述目的。最后，为了正确地结合光伏发电和风力发电电压，采用了带有串并联斩波器的DC-DC变换器。即使太阳辐照度和风速波动剧烈，逆变电路也能稳定工作，通过控制变换器中的占空因数和逆变器中的调制因数，可以向电网提供各自的最大输出功率。
