Real-time digital simulation mimics a physical system to reproduce the system’s true behavior under simulated stresses applied under controlled conditions in a laboratory. In the context of electrical power grids, the applications of real-time digital simulation has grown from its initial function of testing prior to commissioning of control and protection systems (over 30 years ago) to encompass all manner of studies in the generation, transmission, distribution, and end use sectors of electrical energy. High voltage direct current (HVDC) technology is the conduit for bulk power transfer from large conventional generation to distant load centers, between interconnected asynchronous alternating current (AC) grids, and today it is also the key enabler for the massive influx of far-flung renewable generation into AC grids. Advances in power electronic topologies, control and protection schemes are leading the future growth of multi-terminal direct current (MTDC) grids worldwide.

实时数字仿真模拟物理系统，以再现系统在实验室受控条件下施加的模拟应力下的真实行为。在电力网的背景下，实时数字仿真的应用已经从其最初的功能（30多年前）在控制和保护系统的调试之前进行测试，以涵盖发电，输电，配电和最终使用部门的各种研究。高压直流（HVDC）技术是将大容量电力从大型传统发电机传输到远程负载中心的管道，在互连的异步交流（AC）电网之间，今天它也是将遥远的可再生能源发电大量涌入AC电网的关键推动因素。电力电子拓扑、控制和保护方案的进步正在引领全球多端直流（MTDC）电网的未来发展。
