含分布式电源的低压配电网串补双向调压仿真系统设计

含分布式电源的低压配电网中普遍存在较为严重的电压波动问题,传统的稳压方法无法有效解决。该文结合串联补偿原理,分析了基于交流斩波技术的低压配电网双向自动调压实现方法,设计了含分布式电源的低压配电网串补双向调压仿真系统,给出了各种扰动下的电压调整结果,并验证了该方法的有效性。该实验系统从电气专业学生的知识结构出发,通过研-教-学深度融合,能够以问题导向为思路锻炼学生分析与解决实际问题的能力,可有效落实突出能力培养的"新工科"教育改革理念,实践效果良好。

Design on simulation system for series compensation and bidirectional voltage regulation of low voltage distribution network with distributed generator

The voltage fluctuation is serious in the low voltage distribution network with distributed generator.However,the traditional voltage regulation method cannot cope with it effectively.Based on the series compensation theory,this article analyzes the bidirectional voltage regulation method in low-voltage distribution network.The simulation system of bidirectional voltage regulation method in low-voltage distribution network with distributed energy resources is designed.The effectiveness is proved by the simulation results with all kinds of disturbance.Based on the knowledge structure of students with electrical engineering major,scientific achievement and teaching experience can be combined by this way.The system can help students to train how to analyze and settle practical problems by the problem-oriented way.It can implement the"New Engineering"education reform concept of the electrical engineering major,and the practice effect has been proved.
