摘　　要：为了解决传统电站仿真系统无法合理利用电站真实数据的问题,提出电站在线仿真系统。介绍电站在线仿真系统的三个关键技术,给出网络部分的结构模型,并对网络中数据传输的时间延迟部分进行探讨。基于粗糙集理论,分析得出在线仿真控制器节点与在线执行器节点之间的网络时延在总时延中的占比对系统稳定性影响较大,并通过仿真实例给予验证。In order to solve the problem that traditional power plant simulation systems cannot make reasonable use of real data from power plants,an online power plant simulation system is proposed.It introduces three key technologies of the online simulation system for power plants,provides a structural model of the network part,and explores the time delay part of data transmission in the network.Based on rough set theory,it is analyzed that the proportion of network delay between the online simulation controller node and the online actuator node in the total delay has a significant impact on system stability,and verified through simulation examples.
