Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0028] During the simulation, due to the delay in the communication interface between the platform and the hardware, the transmitted data will be misplaced, which will eventually lead to a decrease in the accuracy of the system simulation. Therefore, in this embodiment, a compensation method for communication delay based on a power system digital-analog hybri...

Abstract

The invention provides an electric power system simulation platform communication time delay-based compensation method and apparatus. The method comprises the following steps: an original transmissioncurrent is obtained; the original transmission current is a current between an electric power system digital-analog hybrid simulation platform and a hardware communication interface, a maximum characteristic root of the original transmission current is calculated, total time delay of the electric power system digital-analog hybrid simulation platform and the hardware communication interface is obtained, and a compensated transmission current is obtained according to the maximum characteristic root and the total time delay. The compensation method and apparatus can help solve a problem that low simulation precision of simulation modeling of a direct current device is caused due to time delay of the electric power system digital-analog hybrid simulation platform via conventional technologies, and good error compensation effects can be exerted during real time capacitive current and voltage interaction between the electric power system digital-analog hybrid simulation platform and a hardware board card.

Description

technical field [0001] The invention relates to the technical field of communication between software and hardware in power system simulation, in particular to a communication delay compensation method and device based on a digital-analog hybrid simulation platform of a power system. Background technique [0002] Flexible DC transmission is an important technical means for the development of smart grid. Compared with conventional DC transmission methods, flexible DC transmission has strong technical advantages in island power supply, interconnection of large-scale AC systems, new energy grid integration, etc., and has very broad development prospects. As one of the key equipment to ensure the safe and reliable operation of flexible DC systems: DC equipment plays a very important role in establishing DC grids, improving grid operation flexibility and power supply reliability. [0003] In the simulation analysis of DC system, in order to save simulation resources and improve ...
