Power system real-time frequency regulation simulation and teaching experiments design

为提高电力系统分析课程的教学质量,加深学生对频率动态过程的系统性理解,基于电力系统仿真工具包(simulation toolkit for electrical power systems,STEPS)开发实时仿真功能,可视化展示系统中各电气量的动态响应曲线。结合频率教学相关内容,模拟实际电网的自动发电控制策略,构建电力系统实时调频仿真实验案例,分别模拟电力系统一次调频和二次调频过程。该仿真系统和实验为学生提供交互式模拟频率动态过程的机会,加深学生对所学知识的理解,引导学生参与实验设计并自主优化调频策略,提高学生的基本科研素质。

To enhance the teaching quality of the power system analysis course and deepen students'systematic understanding of frequency dynamic process,the real-time simulation function was developed based on simulation toolkit for electrical power systems(STEPS).This function enabled the visualization of dynamic response curves for various electrical quantities in the power system.Combining relevant teaching content,the automatic generation control strategies for simulating actual power grid were established,creating real-time frequency regulation simulation experiments for primary and secondary frequency regulation process in power system.This simulation system and experiments provided students with the opportunities to interactively simulate the frequency dynamic process,deepen their understanding of the learned knowledge.Meanwhile,the system and the experiments could also guide students to participate in the experiment design and optimize the frequency regulation strategies independently,thereby improving students'fundamental research abilities.
