不希望发生但不可避免的自然事件或人为错误会破坏电力系统的正常运行。工程师必须根据实际判断，为最可能发生的事件应用保护继电器系统，以最大限度地减少服务中断和设备损坏。了解不同继电保护系统的性能和局限性在其应用中至关重要。人们可以解释系统保护的哲学，保护继电器系统的基本理论，以及课堂会话和/或计算机仿真的继电器算法。然而，这是困难的，如果不是不可能的，评估的实际性能和可能的误操作的继电器在现场，只是通过计算机模拟或台式测试。本文介绍了利用能源系统研究中心电力系统仿真实验室加强继电保护教育的教学和科研活动。简要介绍了实验室的配置和继电器测试站的设计。本文还包括一些示例，以说明使用该设施的本科和研究生继电保护系统的教育。
Undesirable but unavoidable natural events or human errors will occur to disrupt normal power system operation. Engineers must apply protective relay systems for the most probable events based on practical judgment to minimize service interruptions and damage to the equipment. Understanding the performance and limitations of different protective relay systems is vital in their application. One can explain the philosophy of system protection, the basic theory of a protective relay system, and the relay algorithms from classroom sessions and/or computer simulation. However, it is difficult, if not impossible, to evaluate the actual performance and possible misoperation of a relay in the field just through computer simulation or benchtop testing. This paper introduces the usage of the Power System Simulation Laboratory at the Energy Systems Research Center to enhance the teaching and research activities in relay education. A brief description of the laboratory configuration and the design of the relay testing station are presented. Some sample examples to illustrate the use of this facility for undergraduate and graduate education in protective relay systems are also included in this paper.
