For lucubrating the UHVDC technologies and the characteristics of UHV integrated AC/DC power systems,the closed-loop simulation model of ±800 kV UHVDC power transmission system was developed based on the RTDS and the world first ±800 kV control and protection equipment designed by Nari-relays Cooperation.
由于能够在任何工况下准确模拟直流输电系统行为的仿真方法只有电磁暂态仿真,所建基于RTDS的仿真模型较之机电暂态仿真模型能够提供更深刻和准确的仿真结果;由于考虑了实际UHVDC控制与保护设备的控制作用,仿真将更能反映实际交直流系统的动态特性和更具备实际工程的参考价值。
