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.)

站长，不好意思... 我将我的信箱写错了... 写成：ddccbbaa@sina.cn了... 前面我传输的文件是：“qibaoshanplan.doc”这个文件，并且，是我的一篇论文底稿，我还想您提出了建议“增加创意文案的文件上载”的类型。 我的名字叫：褚江。 这篇文建，我又重新上传了一下... 我会为我的错误买单，马上我再传一篇论文，是我在《云计算》的课堂上书写的... 希望站长，能够将弟我，重新添加到PUDN的大家庭中。(Master, I am sorry ... I was wrong ... in my mailbox written: ddccbbaa@sina.cn up ... in front of my files transferred are: " qibaoshanplan.doc" the file, and it is my a thesis papers, I would like your recommendations " to increase creative copy of the file upload" type. My name is: Chu River. This CCA, I re-uploaded it ... I' ll pay for my mistake, I immediately re-transmission of a thesis, I was in the " cloud computing" classroom writing ... hope that the station can be The brother I re-added to PUDN the family.)
