储能逆变器双模无缝智能切换系统及其切换方法
摘要：
本发明公开了一种储能逆变器双模无缝智能切换系统，其特征在于，包括：储能式逆变器、DSP、并网开关，储能式逆变器一端与DSP连接，另一端与并网开关连接。本发明还公开了储能逆变器双模无缝智能切换方法。本发明通过接触器实现并离网储能逆变器的双模智能切换，实现了孤岛工况和并网工况的无缝切换，同时确保在两种运行模式切换过程中没有电流、电压的瞬时过冲，有效保护了用电设备免受损坏。
摘要（英）：

The invention discloses an energy storage inverter dual-mode seamless intelligent switching system, which is characterized by comprising an energy storage type inverter, a DSP and a grid-connected switch, wherein one end of the energy storage type inverter is connected with the DSP, and the other end of the energy storage type inverter is connected with the grid-connected switch. The invention further discloses an energy storage inverter dual-mode seamless intelligent switching method. According to the invention, dual-mode intelligent switching of an on-grid and off-grid energy storage inverter is realized through a contactor, and seamless switching between an island operating condition and a grid connection operating condition is realized. Meanwhile, the switching process of the two operating modes is ensures to be free of transient overshoot of current and voltage, thereby effectively protecting electrical equipment from being damaged.
