Introduction of Real Time Digital Simulator-RTDS in Power System

RTDS (Real Time Digital Simulator) is a fully digital electromagnetic transient power system simulator which was created specifically for real time power system simulation, utilizing advanced custom computing hardware and software. It provides power systems simulation technology for fast, reliable, and accurate study of power systems even with complex High Voltage Alternating Current (HVAC) and High Voltage Direct Current (HVDC) networks. It has a short modeling cycle, high dependability and flexibility,big scope of frequency characters , visual results,and its calculation accuracy and model rationality have been proved to be reliable after years of running practice at home and abroad.RTDS technology has many advantages, such as being easy to control and fault process could reappear etc, so it replaces the previous generation of network analyzers which were based on analogue technology. This article introduces the real-time digit simulator's function applications and the software and hardware's structure in detail.
