摘　　要：针对分布式发电系统涉及的电力电子并网装置控制结构多样、建模方式繁杂的特点,构建了一种电力电子装置控制系统通用控制结构。将控制部分分为外环和内环2个通用模块,这些模块内含有模式控制开关,通过改变这些开关的状态,可使外环分别实现功率控制、电压控制、下垂控制及恒压/恒频控制,内环则可实现电流控制。该模型具有很强的通用性,可以表征一大类不同的电力电子并网装置的控制系统结构及控制策略,具有模块化特征,特别适合基于面向对象建模的分布式发电系统仿真软件的开发。According to the diversity of control structure and complexity of modeling methods of power electronics devices in distributed generation system, a universal structure of control system for power electronics devices is proposed. The control system is composed of outer and inner loop controller modules. Both controller modules contain mode switches. By changing the state of mode switches, power control, voltage control, droop control and constant voltage/frequency control can be realized with outer-loop controller, while current control can be achieved with inner-loop controller. The universal model can represent a specific kind of control system structure and control strategy for various power electronic power devices, which are suitable for simulation software development of distributed generation system based on object-oriented modeling.
