随着大学准备或修改他们的电力工程课程，包括对智能电网，微电网，分布式能源和可再生能源的讨论，对适合列入典型的4年制本科工程课程的新材料的需求从未如此明显。为了实现这一目标，一个旧的机器实验室被改造成一个小型电网，可以在并网和电网孤岛微电网模式下运行。本文的目的是设计实验室实验，以补充在本科水平的传统电力系统分析课程。在改造过程中，实验室中六台同步电机中的两台被转换为代表基于实验室的微电网中的分布式发电机组。机电分布式发电机（EDG）的使用具有较低的启动时间允许系统作为传统的电力网络运行，并提供频率和电压变化。学生可以在孤岛模式下实验EDG之间的电压控制和功率共享。在LabVIEW®中开发了实验室电网中央控制器（LGCC），用于协调EDG、公用电网和负载的运行。它的功能类似于中央调度办公室，尽管规模要小得多。2012年秋季学期，密苏里州S & T首次在该实验室开设了一个学分的实验室课程。
As colleges prepare or revise their power engineering courses to include discussions on the smart grid, the microgrid, distributed energy sources and renewable energy resources, the need for new material suitable for inclusion in a typical 4-year undergraduate engineering course has never been more obvious. Toward this effort, an old machines lab was remodelled and converted into a small power network that can be operated in both grid-connected and grid-islanded microgrid modes. The intent of this paper is to devise laboratory experiments to supplement a course in conventional power systems analysis at the undergraduate level. During the remodeling process, two of six synchronous machines in the lab were converted to represent distributed generating units within a laboratory-based microgrid. The use of electromechanical distributed generators (EDG) with a low start-up time allows the system to operate as a conventional power network with provisions for frequency and voltage variations. Students can experiment with voltage control and power sharing between the EDGs in islanded mode. A Laboratory Grid Central Controller (LGCC) was developed in LabVIEW® to coordinate the operation of the EDGs, the utility grid and the loads. Its functions are similar to those of a central dispatch office, albeit on a much smaller scale. A one credit hour lab course held on this laboratory was offered for the first time during the Fall semester of 2012 at Missouri S&T.
