基于OPNET考虑延时特性的小干扰稳定仿真研究
Simulation Research on Small Signal Stability Based on OPNET Considering Delay Characteristic
摘要
Abstract
Application and development of wide-area measurement system (WAMS)has provided a new method for solving the problem of inter-regional oscillation caused by interconnection of large power grids,but time-delay in its communication process may affect control effect of the damping controller using wide area signal and then affect small signal stability of the power system. It is helpful to study influence of the information system on the damping controller and small signal stability by constructing a dynamic co-simulation platform based on cyber-physical power system (CPPS). Thus,based on the commu-nication simulating tool OPNET and combining MATLAB,this paper builds a CPPS co-simulation platform and presents a method for simulating actual random delay by means of normal distribution delay. It proves accuracy and effectiveness of this method by using this co-simulation platform to make simulation on small signal stability of the power system.关键词
