Abstract

The invention discloses a source-network cooperative combination real-time simulation system and an experimental method, and belongs to the field of electric system simulation and control. The source-network cooperative combination real-time simulation system comprises a source side real-time simulation sub system and a network side real-time simulation sub system, the source side real-time simulation sub system comprises a data interface server, a coordinate server, a core switch and a simulation server cluster, and a source side full range simulation model with three thermal power generating units, six hydroelectric generating sets and seven wind power plants is established. The network side real-time simulation sub system comprises a GTFPGA communication card, a PB5 board card and an RTDS real-time simulator, and a regional power grid real-time simulation model is established. The two sub systems are in hardware connection in an SFP photoelectric transmitting and receiving interface mode, and carry out optical communication based on an Aurora protocol. The real-time simulation and control system can simulate various power grid faults and various generator set faults effectively, and can achieve load optimized scheduling among regional power grids and various power plants, operation is simple and convenient, and work stability is good.

Description

technical field

[0001] The invention belongs to the technical field of real-time simulation between a regional power grid and various power sources in a power system, and in particular relates to a source-network coordination joint real-time simulation system and an experimental method. Background technique

[0002] As renewable energy (such as wind power, solar energy, etc.) is connected to the grid on a large scale, due to the randomness and volatility of its output power, the existing grid is facing difficulties in accommodating it. This is no longer a problem of the power system itself in the traditional sense, but a problem of the entire power system that needs to take into account the adjustment characteristics of various power prime movers. Power change / adjustment process and system-level closed-loop control algorithms for network source coordination, plant level, regional dispatching level, and large area dispatching level. But there is no effective method and means...
