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)

sobel vi in labview.this might help or give some basic idea about it.

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.)

为了给变频调速系统提供必要的设计参数，依据空间电压矢量脉宽调制（SVPWM）基本原理，介绍了 异步电动机及 SVPWM 算法在 Matlab/Simulink 环境下的建模过程及基于矢量控制理论的变频调速系统动态 模型建立。详细地阐述了实现仿真的方法，并针对仿真中的关键问题及系统的仿真结果进行了分析。仿真结 果表明，采用该控制系统，电压及转矩波动小，转速响应迅速，系统的各项指标都满足电机实际运行特性要 求。其仿真算法对于实现数字化控制变频调速系统具有一定的价值。 (To provide the necessary design parameters for the actual motor control system, the modeling course of voltage space vector pulse wide modulation（SVPWM）agrithmetic and AC motor under Matlab/Simulink environment are introduced. The dynamic model of variable frequency speed regulating system based on vector control is discussed according to the principle of SVPWM. The new method of realizing simulation, key problems and results of the simulation are analyzed in detail. The experimental simulation results show that this system has smaller fluctuations of voltage and torque, quicker response speed, and all of the indicators accord with the performance of the actual motor. The simulation agrithmetic have value to realize controlling motor with digital signal processing. )
