An all-digital comprehensive simulation platform for power station

Abstract

A comprehensive simulation platform for graphical modeling of a power station realizes graphical modeling of the power grid part, flow network system, and control system of the power station. The established simulation model can not only carry out independent simulation calculation of subsystems or devices, but also carry out joint closed-loop calculation of the whole system model of the whole power station; it can carry out all-digital real-time simulation, and can also carry out simulation analysis experiments; the platform includes a simulation machine module, the real-time calculation data can be automatically linked with the virtual power plant monitoring screen of the simulator or the equipment variables in the virtual equipment or physical subsystems to realize the real-time digital simulator function. The invention directly invokes the simulation model in the analysis and calculation, and conveniently realizes the simulation needs of the power station transient process, medium and long-term process, fluid network, 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...

Problems solved by technology

The real-time simulation data can automatically correspond to the equipment variables of the monitoring screen of the power station. Users can operate and monitor the operation of the entire virtual power station through the same screen operation as the actual monitoring system, so as to achieve the purpose of training, teaching and assessment, and realize the function of the real-time digital simulator of the power station. , due to the use of strict mathematical models, it also solves the problem that traditional simulators are generally only suitable for junior and intermediate training
