摘要

本文提出了一种采用电压源变换器(VSC)技术的多终端高压直流输电系统的控制结构。该研究侧重于高层次的控制，以保持直流电压稳定，减轻由于交流电网中突发事件产生的输入功率变化而引起的振荡，并为系统提供足够的动态响应[1]。除此之外，控制器需要在HVAC电网合规性方面进行验证，为此目的，英国国家电网规范将用于验证频率/电压响应和低电压穿越(LVRT)的实现。因此，将根据MTDC控制目标和网格代码遵从性执行不同的测试。

Integral control of a Multi-Terminal HVDC-VSC transmission system

This paper proposes a control structure of a Multi-Terminal HVDC (MTDC) system employing Voltage Source Converters (VSC) technology. The study focuses on high-level control to keep DC voltage stable, mitigate oscillations due to the change in incoming power produced by contingencies in the AC grid and to provide the system with an adequate dynamic response [1]. Apart from this, controllers need to be validated in terms of HVAC grid compliance and for this purpose the UK National Grid Code will be used for verifying the fulfilment of frequency/voltage response and Low Voltage Ride-Through (LVRT). Thus, different tests will be performed considering the MTDC control objectives and the Grid Code compliance.
