摘要:

现代电力电子技术对智能电网的发展做出了突出贡献。随着电力电子技术的发展,逆变器的应用前景日益广阔。微网是未来智能配电网的一种新的组织形式。并网逆变器是连接微电网和公用电网的核心装置。微网并网逆变器能实现分布式电源并网的基本功能。为了高效完成微网并网,并有效降低并网逆变器对电网的冲击,一些更先进的并网逆变器成了迫切的需求。未来的微网并网逆变技术的发展趋势,是将不同的控制方法进行整合形成复合控制,在向公共电网同步传输有功功率的同时,也能实现无功调节、谐波抑制的功能,可以有效提高并网逆变器的性价比。本文详细介绍了PWM并网逆变器的各种控制策略,以及其优缺点。对各种复合控制策略进行了综述。

The modern power electronics technology makes great contribution to the development of the smart grid. With the progress of the power electronics technology, the inverter is widely used. Mi-cro-grid is a novel organization form of smart grid in the future. The grid-connected inverters are the key devices in micro-grid and extensively concerned in the world. The grid-connected inverter can realize the grid-connection of distributed energy sources. To effectively connect micro-grid into utilities and validly reduce the influence of grid-connected inverter for utilities, some grid- connected inverters with advanced functionalities are emergently expected. The prospective in-verting techniques should be the compound and complex control systems by combination of dif-ferent control strategies, with active power transfer, inactive power regulation and harmonic suppression simultaneously achieved. Grid-connected inverter gets higher performance-price ratio. The control strategies for PWM inverters are introduced in detail, as well as their advantages and disadvantages. A variety of the control strategies for PWM grid-connected inverter are reviewed.
