Problems solved by technology

Real-time, high-speed, continuous, stable, and reliable data transmission is required between the RTDS microsecond-level real-time simulation system and the source-side millisecond-level real-time simulation system. Because the simulation time steps of the two are inconsistent, there is currently no effective method and means

Abstract

The invention discloses a source-network coordinating combination real-time simulation system and data transmission method based on an RTDS, and relates to the field of power system simulation and control. The source-network coordinating combination real-time simulation system comprises a source side millisecond-level real-time simulation system and a network side RTDS microsecond-level real-time simulation system, wherein the source side millisecond-level real-time simulation system is formed by connecting a GTFPGA board card and a PB5 board card in an SFP photoelectric receiving and dispatching interface mode, and the network side RTDS microsecond-level real-time simulation system is formed by a data interface machine and a coordinating server through a TCP / IP protocol in a data buffering block mode. Data transmission between the source side millisecond-level real-time simulation system and the network side RTDS microsecond-level real-time simulation system is achieved through the data transmission between communication interfaces. According to the data transmission method, the data transmission between the two simulation systems is achieved through the data transmission between the communication interfaces, working stability is enhanced, and the anti-jamming capability of the simulation system is improved.

Description
