An Interconnected Power System Educational Laboratory

9452344 Nwankpa互联电力系统实验室旨在让学生了解在操作和控制现代电力系统时所表现出的重要现象。这个实验室的主要特点是，它使用真实的发电机、变压器、电机、负载和继电器通过传输线相互连接，形成一个频率为60赫兹、电压水平为22伏的电力系统。在这样的实验室工作中获得的经验是很难使用软件模拟包获得的。电力课程有四个正在进行的实验室，学习机器、保护继电系统、电力电子和高压，这些实验室正在相互连接，使学生有能力实际学习相互连接的部件的动态和操作。该系统通过一组模拟能量管理系统(EMS)和远程终端单元(RTU)的个人计算机(PC)进行监视和控制。这使学生能够很好地了解系统的动态、其局限性和控制方法。本质上，一个真正的现代电力公司EMS中心的简化版本掌握在学生手中。

9452344 Nwankpa The interconnected power system laboratory is designed to give the student an understanding of the important phenomena exhibited when operating and controlling modern day power systems. The main feature of this laboratory is that it uses real generators, transformers, motors, loads and relays interconnected through transmission lines to form a power system which operates at a frequency of 6O Hz and voltage level of 22O V. Experience gained at working in such a laboratory cannot be easily obtained using a software simulation package. The power curriculum has four on-going laboratories for studying machines, protective relaying systems, power electronics and high voltage, which are being interconnected so that students have the ability to practically learn about the dynamics and operation of the interconnected components. The system is monitored and controlled via a set of personal computers (PCs), which emulates an energy management system (EMS) and remote terminal units (RTUs). This allows the student to obtain a good understanding of the dynamics of the system, its limitations and methods of control. In essence a reduced version of an actual modern-day EMS center for a power utility is at the hands of the student.
