电力电子负载（power electronics load ，PEL）作为新型电气实验模拟负载装置，不仅可以模拟多种负载装置对电源产品进行多种检验测试，而且能把被测电源设备的能量回馈给电网，是一种绿色环保节能设备。但在恶劣的工况下PEL的动态性能与模拟指令电流突变，被试电源（device be tested ，DBT ）电压突变和电网电压变化有关，为了抑制上述扰动对 PEL的影响，提出了一种基于功率平衡的前馈控制和基于风电并网的低电压穿越技术。并使用仿真和实验验证前馈控制方法的正确性和有效性。

Power electronic load as a new experimental simulator of electrical load device not only can simulate a variety of load devices for power products to be tested ,and also can bring power back to the grid ,so it is a green and energy‐saving device .However in severe conditions the relationship between PEL dynamic performance and mutation of simulation instruction current ,mutation of voltage of DBT ,the change of grid voltage is concluded .And the feedforward control strategy based on pow er balance w hich is used to restrain the effect of above disturbance on the PEL is put forw ard .Sim‐ulation and experimental results verify the correctness and effectiveness of the control schemes .
