Power Systems
电力系统是电气工程专业的核心专业课程，讲授电力生产、传输、分配与运行分析的基本理论。课程内容包括电力系统组成与额定电压、输电线路与变压器的参数及等值电路、标幺制与网络方程、潮流计算的牛顿-拉夫逊法与快速解耦法、短路故障分析与对称分量法、发电机与系统稳定性、电力系统调度与无功补偿。课程为从事电力调度、规划与运行工作奠定基础。
Power Systems is a core course for electrical engineering majors, teaching the basic theory of generation, transmission, distribution, and operation of power systems. Topics include system configuration and rated voltages, line and transformer parameters and equivalent circuits, per-unit system and network equations, Newton-Raphson and fast decoupled power flow, short-circuit fault analysis with symmetrical components, generator and system stability, and dispatch with reactive power compensation. It lays the foundation for power dispatch, planning, and operation.
学生使用 MATLAB 或 PowerWorld 搭建 IEEE 14 节点标准测试系统，采用牛顿-拉夫逊法完成潮流计算，分析节点电压与支路功率分布。在此基础上调节变压器变比与无功补偿装置容量，优化系统网损，要求网损下降不低于 5%。撰写报告附潮流图与优化前后对比数据，提交程序代码或工程文件。
Students use MATLAB or PowerWorld to build the IEEE 14-bus standard test system, perform power flow using the Newton-Raphson method, and analyze bus voltages and branch power distribution. They then adjust transformer tap ratios and reactive compensation capacity to reduce system losses by at least 5%. Submit a report with power flow diagrams and before/after comparison data, along with code or project files.
