讲述基于定子电流补偿理论的永磁同步电机弱磁控制策略研究(Research on Weak Magnetic Control Strategy of Permanent Magnet Synchronous Motor Based on Stator Current Compensation Theory)

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.)

说明：  以齿轮箱的历史故障数据为依据,提出了齿轮故障诊断数据仓库的功能架构,并对数据的收 集、集成、存储等方面进行了研究,建立了齿轮故障诊断模型。为齿轮故障诊断提供了一种新的方法。 (The functional structure of datawarehouse of gear fault diagnosis is proposed based on gear fault date previously. Research on data collect, data integration, data storage is carried out. The diagnosis model of gear fault diagnosis is established. A newmethod of gear fault diagnosis is provided )

论文写作中最好的画图软件 解压后，先安装软件，结束时不要直接启动软件，先用破解过的2个exe文件替换安装目录的同名文件，再双击reg文件进行注册即可。(The best essay writing drawing software After decompression, install the software, do not start the software directly to the end, the first two with a cracked exe file to replace the installation directory of the same file, and then double-click the reg file to be registered.)
