System Characterisation and Component Modelling for a Power Hardware-in-the-Loop System

实时硬件在环（HIL）仿真平台彻底改变了电力系统评估。通过将功率放大器与HIL系统相结合，将实际功率设备连接到平台中的模拟电网中进行power -HIL仿真。然而，电源设备和PHIL平台由于其非线性和延迟特性而表现出不稳定性问题。因此，PHIL系统会产生振荡，并且运行不稳定，这阻碍了项目合作伙伴RTDS技术公司等电力系统仿真公司的采用。拟议的项目将确定在PHIL系统中观察到的不稳定性的原因。PHIL中的每个组件将使用增益相位分析仪进行表征，并建模以研究组件的频率响应。这些特征可用于确定不稳定的原因，并通过PHIL设置对其进行验证。这是一个与RTDS技术公司合作的为期6个月的项目，包括建模、表征、系统实现和实验评估。本项目将培训2名HQP。在项目结束时，实验室设置和技术报告将移交给公司，这将通过提供稳定的电力设备评估平台使RTDS技术公司受益。

Real time Hardware-in-the-Loop (HIL) simulation platforms have revolutionized power system evaluation. By using a power amplifier with a HIL system, real power apparatuses can connect to a simulated grid in the platform to perform Power-HIL simulations. However, power apparatuses and PHIL platforms exhibit instability issues due to their nonlinear and latency characteristics. As a result, PHIL systems generate oscillation and suffer from unstable operation, and this has prevented their adoption by power systems simulation companies like project partner RTDS Technologies Inc. The proposed project will identify causes for instability observed in PHIL systems. Each component in the PHIL will be characterized using a Gain-Phase analyser and modelled to study the frequency response of the component. These characteristics can be used to determine the cause of the instability and verify them with a PHIL setup. This is a 6-month project working with RTDS Technologies Inc. that includes modelling, characterization, system implementation, and experimental evaluation. Two HQP will be trained in this project. A laboratory setup and technical reports will be transferred to the company at the end of the project, and this will benefit the RTDS Technologies Inc. by providing a stable power apparatus evaluation platform.
