光纤射频传输系统中相干正交频分复用的研究，介绍了系统的结构和性能,是一份很不错的学习材料。(Coherent optical fiber radio transmission system using orthogonal frequency division multiplexing, introduces the system structure and performance, is a very good learning materials.)

本压缩包 包含 任务书、论文以及答辩ppt，虽说是课程设计，但是按照毕业设计书写，内容充实 本次课程设计主要是对象湖变的电网进行保护整定，对d1至d6共6个地方进行了最大方式与最小方式运行情况下的短路电流计算。计算完短路电流后，对L1至L5共5条线路进行电流保护整定。但是由于线路较短，线路阻抗较小。经计算后均不适合三段式电流保护。所以采取了纵联差动保护作为主保护，定时限过电流保护作为后备保护。对于变压器，采用纵联差动保护与气体保护共同作为主保护，过负荷保护作为后备保护。(The curriculum design is the object variable grid lake protection setting of D1 to D6, 6 places for the maximum and minimum operation mode under the condition of short-circuit current calculation. Calculation of short-circuit current after the end, L1 to L5 a total of 5 lines of current protection setting. But because of shorter lines, line impedance is small. The calculations are not suitable for three phase current protection. So take a longitudinal differential protection as the main protection, timing and limiting current protection as a back-up protection. For transformers, using longitudinal differential protection and gas protection as the main protection, overload protection as a back-up protection.)

DAQ数据采集基础，介绍数据采集的基本组成，和各元素注意事项。(DAQ data acquisition based on the basic composition introduced data collection, and the elements of note.)

说明：  PLC、变频器在中央空调节能改造中的应用，本人从事这方面工作，感觉帮助很大(PLC, inverter in the central air-conditioning energy saving application, I have engaged in this work, feeling very helpful)

该程序是我硕士毕业论文《单相并网逆变器》源程序，调试成功的。（直流直接逆变为交流的单相全桥逆变拓扑，有离网并网功能，锁相环过零检测再采用PI.）(This program is my master' s thesis, " single-phase grid-connected inverters," the source, debugging success. (DC-AC inverter direct single-phase full-bridge inverter topology, there are off-grid and network functions, PLL zero crossing detection and then using PI.))
