Good knowledge of VSC-HVDC technology is presently held only by the manufacturers (who for competitive reasons do not want to share). Given the potentially large number of VSC-HVDC links into the UK, and the rapid planned rollout of the technology the utilities and government need to develop a better understanding of VSC-HVDC. A key weakness is that presently most public domain R&D on VSC-HVDC is based on simplified simulation models. This fails to capture key hardware complexities. The limitations real-time control places on system operation is a key element here. Nonlinearities in the hardware are a further problem. There is an urgent need for research to develop a low-power hardware model that particularly addressed the real-time control issues to develop better models of this component and allow the utility networks to develop a better understanding of the hardware. The PhD will construct a low-power reduced-scale hardware model of a modular multi- level VSC-HVDC converter. As far as possible the control dynamics will be preserved so that the controller for each sub-module will be partitioned from the master controller, to test multi-layer control concepts. Algorithms for such system control will be explored. The fidelity of power system models presently used for network modelling will be assessed in this context, and improvements suggested as appropriate. If time permits, interfacing the hardware model with Real-Time Digital Simulation (RTDS) will be examined of the type used in the UK utility MTTE project. The PhD will involve software programming (both FPGA and microcontroller), real-time control, sensing and measurement, electronics, power electronics, hardware-in-the-loop, as well as some power systems modelling and analysis.

VSC-HVDC技术的良好知识目前仅由制造商持有（由于竞争性的原因不想分享）。鉴于可能有大量的VSC-HVDC链接到英国，并且公用事业公司和政府需要对技术的快速推出，以便对VSC-HVDC有了更好的了解。一个关键的弱点是，目前，VSC-HVDC上的大多数公共领域研发都是基于简化的仿真模型。这无法捕获关键的硬件复杂性。实时控制位置在系统操作上的限制是这里的关键元素。硬件中的非线性是另一个问题。迫切需要研究开发低功率硬件模型，该模型特别解决了实时控制问题，以开发出该组件的更好模型，并允许公用事业网络对硬件有更好的了解。博士将构建模块化多级VSC-HVDC转换器的低功率降低硬件模型。将尽可能保留控制动力学，以便将每个子模块的控制器从主控制器分开，以测试多层控制概念。将探索用于此类系统控制的算法。在这种情况下，将评估目前用于网络建模的电力系统模型的保真度，并在适当的情况下进行改进。如果时间允许，将检查硬件模型与实时数字仿真（RTD）的连接，将检查英国公用事业项目中使用的类型。博士学位将涉及软件编程（FPGA和微控制器），实时控制，传感和测量，电子，电力电子，硬件在环上以及某些电源系统建模和分析。
