Embodiment Construction

[0026] figure 1 It is a schematic diagram of the composition principle of the impact load modeling system based on actual measurement of the present invention. figure 1 , the data acquisition card of the front PC collects the shock load information into the front PC, and the host in the station monitors the shock load data collected by the front PC in real time through the serial port; the remote host communicates with the front PC through the dedicated network. Communication, realize remote data file management, remote setting and downloading of fixed value files, system file management and real-time data display; background analysis software processes the data of the remote host, and combines the load survey information to use the impact load. The modeling platform is used for modeling and analysis, and finally the load model parameters are added to the power system simulation software to participate in the calculation.

Abstract

The invention provides an impact load modelling system and a method on the basis of practical measurement, belonging to the measurement and identification technique field of impact characteristic load modelling of modern power system; the system comprises six parts: a micro-computer typed impact load dynamic characteristic recording instrument, an impact load modelling platform, a remote management system, an impact load surveying information platform, a background analysis software system and a power system simulation software interface; the technical proposal of the invention is that digital data collecting, processing, managing and exchanging system which uses computer technique as core is combined with the practical production; a load model which can describe the impact load characteristic is established by the impact load modelling platform; the established impact load model is applied to the digital simulation analysis of power system by the interface of the power system simulation software.

Description

technical field [0001] The invention relates to the technical field of measurement and identification of impact characteristic load modeling of modern power systems, in particular to an impact load modeling system and method based on actual measurement. Background technique [0002] The development of power system digital simulation technology provides an economical and convenient means for studying the stability of power system under various disturbances, examining the effects of various stabilization measures and the performance of stability control. At present, digital simulation has become the main tool for power system planning, design and operation. The accuracy of digital simulation results directly affects the correctness of decision-making in operation and planning. The degree of agreement between the digital simulation of the power system and the actual situation depends on the accuracy of the model used, which directly affects the simulation results and the decisi...
