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.)

GNT08.1.2
gps导航工具包，可用于分析GPS误差，伪距及导航融合算法(This report include the review of
• Principle of Radio Navigation: navigation base on trilateration has been investigated and the over determined Eq. for navigation has been solved.
• GPS Ephemeris Data: for GPS navigation, the position of GPS satellite is very important so the by receiving ephemeris data the position of the satellite is determined.
• GPS Errors: Three different sources of errors in GPS navigation has been investigated (Ionosphere, Troposphere and Satellite clock). Ionospheric Error model is generated base on Parkinson [1] and the Tropospheric Error Model based on Hopfiel model [2].
• Simulation & GPS Toolbox: One of the targets of this work is generating Matlab GPS Toolbox and in one case study the performance of generated toolbox will be verified.)
