A kind of rtds data transmission device and method based on serial port communication

Abstract

The invention relates to an RTDS data transmission device and method based on serial port communication, belonging to the technical field of data transmission. In the present invention, by setting the RTDS serial communication simulation module library between the RTDS simulation system and the terminal equipment, the data sent by the RTDS simulation system to the terminal equipment is synthesized into a message of a corresponding format and then sent to the terminal equipment through the RTDS input and output board. When the device sends data to the RTDS simulation system, the data is sent to the RTDS serial communication simulation module library in the form of a message. The RTDS serial communication simulation module library judges the validity and type of the message data through the check code and flag bit of the message. And distribute the effective message data to different positions of the RTDS model according to the type. The serial port communication mode of the present invention enables the RTDS simulation system to be flexibly connected to terminal equipment such as monitoring platforms, relay protection measurement and control devices, and solves the situation that the RTDS simulation system can only be connected to terminals through hard wiring.

Description

technical field [0001] The invention relates to an RTDS data transmission device and method based on serial port communication, belonging to the technical field of data transmission. Background technique [0002] The full name of RTDS is Real Time Digital Simulator (Real Time Digital Simulator). It was developed and manufactured by RTDS Company in Manitoba, Canada. It is a device specially designed to study electromagnetic transient phenomena in power systems. It has been widely used at home and abroad In the simulation research and experiment of AC relay protection and DC control protection of power system. By establishing the simulation model closest to the actual power system, it realizes the real-time simulation of the power system in the way of large-scale DSP parallel computing and operation. It forms a closed-loop system through hard-wired communication with the actual control and protection devices. That is to say, it is possible to conduct simulation research on va...
