  用GAL16V8设计可变长度序列信号发生器,在掌握伪随机序列性质的基础上,设计给定长度的伪随机序列信号发生器,也即设计给定n后(n为移位寄存器的级数)最长线性反馈移位寄存器序列。并在给定n产生的最长序列的基础上,截短出课题给出的序列长度,并用FM软件对可编程器件GAL16V8进行编程,以实现长度不同的序列信号发生器。(GAL16V8 design variable-length sequence signal generator based on the master pseudo-random sequence nature, the design of a given length pseudo-random sequence Signal generator, designed for the series) up to linear feedback shift register sequences given n (n is the shift register. And given n Sequence length given by the subject on the basis of the longest sequence, truncated, and FM software for programming the programmable device GAL16V8, in order to achieve Different length of the sequence signal generator.)

7. TheDesignof35kVGridRelayprotection

  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.)
