基于电流分解的逆变器无连线并联控制

针对基本 PQ 控制法对非线性负载均流性能较差的缺点,采用了基于电流分解的方法对逆变器进行无连线并联控制。给出了功率均分和电流分解原理,提出了逆变器并联控制的实现方案和 DSP 在并联控制中的应用。实验表明,该方案对于非线性负载也具有很好的均流性能。

Wireless and parallel operation control technology of inverters based on current decomposition

Wireless and parallel operation control approach based on current decomposition has been developed for independent inverters,which have the shortcomings of poor capability of current sharing for the nonlinear loads used basic PQ control approach. To start with,the principles of power sharing and current decomposing are introduced,then parallel operation control scheme and the application of DSP are supplied.The results of experiment have illustrated that the system has good capability of current shar- ing for the nonlinear loads.
