Abstract

An all-digital comprehensive simulation platform of a power station achieves graphical modeling of a power station power grid part, a flow net system and a control system. The established simulation models can perform independent simulation calculation of subsystems or devices or the like, united closed-loop computation of all system models of the whole power station, all-digital real-time simulation and simulation analysis experiments. The platform comprises a simulator module, real-time calculated data can be automatically linked with simulator virtual power station monitoring images or equipment variations in virtual equipment or physical subsystems, and then functions of the real-time digital simulator can be achieved. The platform directly calls the simulation models in analysis and computation, and conveniently meets simulation demands of a power station transient process, a middle-and-long term process, a flow network, the control system and the like.

Description

technical field [0001] The invention relates to an all-digital comprehensive simulation platform for a power station, which belongs to the field of electric power system digital simulation. Background technique [0002] Existing real-time digital simulation systems generally use mature electromechanical transient simulation programs or electromagnetic transient simulation programs. Real-time digital simulation focuses on realizing the interface with the physical system, so as to realize the testing and inspection of the physical system with the digital simulation system, and Use a dedicated hardware platform, which is expensive, such as RTDS, ADPSS, etc., to highlight the accuracy of the simulation results and the real-time performance of the calculation. Taking ADPSS as an example, the mature electromechanical transient simulation program of PSASP is used as the core calculation program; taking RTDS as an example, the mature electromagnetic transient simulation program of E...
