基于OPNET的继电保护信息系统信息流仿真方法

Simulation Methods for Relay Protection and Fault Information System Information Flow Based on OPNET

目前对保信系统信息流的研究主要是以运行实测为主的工程应用,没有深入分析信息流特性以及建立相关的模型,因此很难把握信息流对保信系统的关键影响因素,不利于分析和处理电网故障信息。基于上述现状,提出一种保信系统信息流仿真方法,先分析了信息流的仿真需求;再建立保信系统关键对象的仿真模型;最后基于OPNET对保信系统典型的应用业务进行仿真。通过对仿真结果进行分析,验证该仿真方法的可行性和实用性。

The interactive information flow between its master station and sub-station reflects relevant information of protection devices, fault recorder and other equipment, revealing the operation condition of power grid indirectly. The study of PI system information flow, nevertheless, concentrates on the engineering applications based on operation measurement currently without making any in-depth analysis of the characteristics about the information flow nor building any related models, which makes it difficult to investigate how the information flow affects PI system and it is thus not conducive to the analysis and process of power grid failure information. Given the above situation, the paper has put forward a simulation method of PI system information flow. It has analyzed the simulation demand of information flow, establishing a simulation model about the key objects of PI system and simulating the typical business of PI system information flow, this paper has managed to verify the feasibility and Practicability of simulation method.
