|
摘要
协调控制是保证交直流混合配电系统稳定运行的核心技术。针对多电力电子变压器互联的10kV中压交直流混合配电系统设计了集中式协调控制方案。首先提出了电力电子变压器站控层控制器的统一架构,然后提出了稳态和故障两种工况下系统的协调控制方案。最后基于RT-Lab设计了半实物仿真实验平台并将其用于实验验证。实验结果证明了所提出的协调控制方案的有效性。
Coordinated control is the core technology to ensure the stable operation of AC/DC hybrid distribution systems. In this paper, a centralized coordinated control scheme based on interconnected communication is designed for power electronic transformer based 10 kV AC/DC hybrid distribution system. Firstly, the unified architecture of the controller of the PET station control layer is proposed. Secondly, the coordinate control strategies under steady state and fault state are proposed. Finally, a hardware-in-the-loop simulation platform is designed based on RT-LAB and is used for experimental verification. The experimental results prove the effectiveness of the proposed coordinated control scheme.
