Flexible direct current power transmission full-digital real-time simulation device based on RTDS

The invention discloses a flexible direct current power transmission full-digital real-time simulation device based on a RTDS. The simulation device comprises a host computer region, a RACK region, a valve control region and a MMC current conversion valve region. Through simulation of control protection programs of valve control and a current converter pole, flexible direct current primary devices and control protection logics can be simulated, a RTDS full-digital simulation system can be formed, closed loop test is indirectly achieved and advantages of the RTDS real-time simulation test can be brought into play. The C language can be directly into a function module, so the operation is simple, a logic language conversion problem does not exist, the operation is simple and convenient and test results are precise and reliable. 本发明公开了种基于RTDS的柔性直流输电全数字实时仿真装置，上位机区、RACK区、阀控区和MMC换流阀区，通过对阀控和换流器极控制保护程序的模拟，能够模拟柔性直流次设备和控制保护逻辑，能够构成RTDS全数字仿真系统，间接实现了闭环测试，可发挥RTDS实时仿真测试的优势；C语言可直接转化为功能模块，操作简单，不存在逻辑语言转化问题，操作简单方便，测试结果准确可靠。
