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 10kV 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.
