Accordingly, small wind power grid system is an inevitable trend of wind development. A wind power inverter used in independent / grid dual mode is proposed in the paper, which analyzed the main circuit structure of dual mode inverter. 因此,小风电系统的并网是风电发展的一个必然趋势。本文研究一种适用于独立/并网双模式的小风电逆变器。
Meanwhile, a relatively perfect dual - mode dialogue function is realized with the usage of a double line tranformation circuit. 采用双线变换电路,实现较完善的双工对讲功能。
