Problems solved by technology

However, these distributed real-time simulation systems do not consider the transmission efficiency of model data in distributed systems, and in these distributed simulation systems, the simulation model required by a certain site is transmitted by a site with a complete model. It takes a long time and the network transmission efficiency is low, which greatly affects the real-time performance of the simulation

Abstract

The invention discloses a rapid transmission method of model data in distributed simulation of power equipment. The method comprises the steps of constructing a network topological graph of each site in a simulation system of the distributed power equipment, obtaining mean data transmission time between the sites, generating a shortest path tree taking a target site as a root node by using a Dijkstra's algorithm, generating a structure tree of a simulation model, analyzing a required submodule in a target included in each site, forming a submodule transmission candidate list, carrying out submodule transmission path planning from small to large from a leaf node according to the transmission time based on the list and the structure tree of the model to achieve rapid distributed transmission of the simulation model of the power equipment. The method greatly improves model transmission efficiency in the distributed simulation system, shortens the transmission time of a model network, and therefore ensures a simulation effect and continuity.

Description

technical field [0001] The invention belongs to the technical field of power system simulation, and relates to three-dimensional simulation technology, in particular to a method for fast transmission of model data in distributed power equipment simulation. Background technique [0002] Power system simulation technology can be divided into two categories: physical simulation and digital simulation. Among them, real-time digital simulation technology has been more and more widely used in power system test research, and the development of computer technology and distributed control technology has further promoted the in-depth development of real-time digital simulation technology. In recent years, power system simulation technology is changing from centralized simulation control system to distributed simulation control system. Distributed simulation technology is an advanced simulation technology, which is based on computer network simulation and is mostly used for simulation...
