Abstract

This paper presents new simulation software that allows the efficient and accurate fixed-time-step simulation of complex event-based dynamic systems. The software, named ARTEMIS/sup TM/ (Advanced Real-Time Electro-Mechanical Transient Simulator), accurately simulates time-segment linear systems with discontinuities occurring anywhere between time-steps. The new software is used for the simulation of energy and power system dynamics, and is implemented in the ARTEMIS Add-On for Simulink's Power System Blockset. With ARTEMIS Discrete Time Compensation of Switching Events (DTCSE), the between-step events are transparently taken into account and compensated for in the simulation results. This eliminates sub-synchronous jitter while causing only minor increase in both the average time-step and real-time time-step (typically less than 1.0%) making ARTEMIS with DTCSE suitable software for real-time simulation of precision-critical hardware-in-the-loop (HIL) systems. The DTCSE algorithm is very good at handling typically challenging fixed-time-step simulation cases, like multiple single time-step discontinuities.

用于电力系统精确实时仿真的开关事件离散时间补偿

本文提出了一种新的仿真软件，可以对基于事件的复杂动态系统进行高效、精确的固定时间步长仿真。该软件名为ARTEMIS/sup TM/(高级实时机电瞬态模拟器)，可以精确地模拟时间步长之间任何地方发生不连续的时间段线性系统。新软件用于能源和电力系统动力学仿真，并在Simulink电力系统块集的ARTEMIS附加组件中实现。利用ARTEMIS开关事件离散时间补偿(DTCSE)，可以在仿真结果中透明地考虑和补偿步间事件。这消除了次同步抖动，同时只导致平均时间步长和实时时间步长小幅增加(通常小于1.0%)，使具有DTCSE的ARTEMIS适合用于实时仿真精度关键的硬件在环(HIL)系统。DTCSE算法非常擅长处理典型的具有挑战性的固定时间步长模拟情况，如多个单时间步长不连续。
