Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] The invention provides a power grid long dynamic process simulation method based on the PSS / E power flow calculation API interface. Firstly, the power grid model is generated by analyzing and importing CIM / E, BPA and other format data files, including the generation of simulation real-time database and PSS / E power flow data files. Then use the API interface provided by PSS / E to realize the external drive of PSS / E power flow calculation through the secondary development and packaging of the interface. Finally, a custom model of the generator governor is established, and the power grid frequency calculation and generator primary frequency regulation function simulation are performed. The simulation results interact with the PSS / E power flow calculation through the interface, and the node injection of the system is changed, so as to realize the characteri...

Abstract

The invention provides a long-dynamic-process simulation method based on a PSS / E trend API. The method includes the following steps of establishing a power grid model, forming a PSS / E trend calculation interface layer, calling the interface layer to calculate a trend and building a simulation system to achieve long-dynamic-process simulation of a power grid. The method achieves control over the whole PSS / E trend calculation process of an external application program; the simulation method maintains the accuracy of PSS / E trend calculation, further extends the functions of PSS / E trend calculation, and achieves long-dynamic-process simulation of the power grid; the method supports the mode that modeling is conducted through leading-in from model files in various standard data formats, and has high flexibility and adaptability; according to the method, a Fortran API provided by PSS / E is used, the Fortran API can be directly called by C++ and the like, can be directly embedded into a developed program of a user and is suitable for development of a large-scale application program.

Description

technical field [0001] The invention relates to a power system analysis method, in particular to a long dynamic process simulation method based on a PSS / E power flow API interface. Background technique [0002] Automatic generation control (AGC) and other control software are widely used in dispatching at all levels, and play an important role in stabilizing the power grid. With the advancement of my country's smart grid construction, the scale of the power grid has been further expanded, and an integrated power grid connected by UHV main grids has gradually formed. The electrical connection between the power grids has become closer, the difficulty of operation control has increased, and the active power control strategy of the power grid has become more complicated. And refinement, the correctness of the control strategy has an increasing impact on the security of the power grid, and the strategy needs to undergo rigorous testing and simulation verification before it is put ...
