Hardware-in-the-loop systems are an essential tool to verify controllers and deployed control algorithms in a risk-free environment. The inaccessibility of the converters used in applications such as pumped hydro storage power plants due to their high ratings, require the development of a hardware-in-the-loop platform to perform the validation of the deployed control structures and algorithms. This paper presents the modeling and splitting of the model of the matrix modular multilevel converter to allow the usage of small-scale simulators, such as the RT Boxes, to deal with the complex system exceeding capabilities of a single unit. To achieve an acceptable simulation step-size, this paper demonstrates the splitting of the model into multiple independent instances using the concept of virtual capacitance implementation. The verification of the proposed concept is done on a hardware-in-the-loop system compromising ten RT Boxes, where the physical model of the matrix modular multilevel converter is deployed, and control algorithms are implemented on the ABB PEC800 industrial controllers.

使用小型模拟器的 HIL 系统的 M3C 分布式实时模型

硬件在环系统是在无风险环境中验证控制器和部署的控制算法的重要工具。抽水蓄能电站等应用中使用的转换器由于额定值高而无法访问，因此需要开发硬件在环平台来执行部署的控制结构和算法的验证。本文介绍了矩阵模块化多电平转换器模型的建模和拆分，以允许使用小型模拟器（如 RT Box）来处理超出单个单元能力的复杂系统。为了获得可接受的仿真步长，本文演示了使用虚拟电容实现的概念将模型拆分为多个独立实例。
