Abstract

Voltage-Source Converter-Based High-voltage dc (VSC-HVdc) technology has received growing interest during recent years due to its benefits for separated active and reactive power control. Before the installation of VSC-HVdc links, different simulation-based studies need to be performed, usually by different parties and using different electromagnetic transient (EMT) simulation platforms. This paper provides a systematic method to assess discrepancies between simulation tools. Models of the VSC and its control systems are implemented from scratch in two different tools. A metric and a methodology to quantitatively assess the discrepancies between simulation results is proposed and illustrated. The paper shows that even with a pedantic re-implementation of the models from the ground up, simulation results are still inconsistent. The objective of this paper is to develop a quantification method for comparing the models developed in different EMT simulation tool and to emphasize differences that can arise with the numerical solvers in such tools.

EMT工具中VSC-HVdc控制器仿真的定量评估方法

基于电压源变换器的高压直流(vcs - hvdc)技术由于其分离有功和无功控制的优点，近年来受到越来越多的关注。在安装vcs - hvdc链路之前，需要进行不同的基于仿真的研究，通常由不同的方使用不同的电磁瞬变(EMT)仿真平台。本文提供了一种系统的方法来评估模拟工具之间的差异。VSC及其控制系统的模型在两种不同的工具中从零开始实现。提出并说明了定量评估模拟结果之间差异的度量和方法。本文表明，即使对模型进行了彻底的重新实现，仿真结果仍然不一致。本文的目的是开发一种量化方法来比较不同EMT模拟工具中开发的模型，并强调这些工具中数值解算器可能出现的差异。
