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

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
technical field [0001] The invention belongs to the technical field of joint scheduling between regional power grids and various power sources in a power system, in particular to an RTDS-based source-network coordination joint real-time simulation system and a data transmission method. Background technique [0002] The joint dispatching technology of the power grid and various new energy sources (such as wind power, solar energy, etc.) is one of the difficulties in the current research of power systems at home and abroad. It uses RTDS microsecond real-time simulation power grid operation, and uses source-side millisecond-level full-scale simulation systems such as thermal power units, wind turbines, pumped storage units, energy storage systems, solar photovoltaic power generation and solar thermal power generation as power points to form various power sources. The joint real-time simulation system of source-grid coordination combined with the power grid can be used as a rese...
