摘要
通过建立基于输电线路运行电热耦合的虚拟仿真交互实践教学系统,有效克服传统电力系统课程的不足.在虚拟仿真技术的支持下,通过分析电热耦合模型,建立了电力系统电热耦合潮流模型和算法;结合导体本身热惯性的特点,研究了在不同外界条件变化情况下的电热耦合过程,揭示了制约输电线路电热耦合特性的影响因素.实践证明,该实践教学系统能够有效提高学生的实际操作水平.
Abstract
By establishing a virtual simulation interactive practical teaching system based on the electro-thermal coupling of trans-mission line operation,the deficiency of traditional power system courses is effectively solved.With the support of virtual simula-tion technology,the electro-thermal coupling model is analyzed to establish the power system electro-thermal coupling load flow model and algorithm.Combining the characteristics of conductor thermal inertia,the electro-thermal coupling process under differ-ent external conditions is studied,and the influencing factors on the electro-thermal coupling characteristics of transmission lines are revealed.The practice has proven that this practical teaching system can effectively improve the practical operation level of students.
