This paper presents a comparison of results between inserted and non-inserted series compensation technology in the network during healthy and faulty conditions. The numerous types of fault have been examined in compensated and uncompensated conditions. It was found in the literature that the transfer of power without series compensation led to increase the transient current and voltage. Therefore, a fixed series compensation scheme is adopted in normal and faulty conditions of the transmission line to solve the problem mentioned above using MATLAB/SIMULINK. Also, this paper introduces the addition of two compensated units associated with a suitable protection system in a transmission line. This technique can improve the performance of 500 kV extra high voltage transmission line and mitigate the fault current magnitude during various type of faults such as phase to ground (Ph-G), double phase to ground (2Ph-G), three phase to ground (3Ph-G). In addition, concerning the overvoltage problems across a series capacitor bank during the disturbance, the system is boosted by a protection technique associated with a suitable control system. The design is inserted into the system to protect the series capacitor bank, which in turn overcomes the severity of overvoltage on several types of faulty conditions. It also simulated and evaluated with the help of MATLAB/SIMULINK.

本文介绍了在健康状况和故障状况下，网络中插入式和非插入式串联补偿技术之间的比较结果。在补偿和未补偿条件下检查了多种类型的故障。在文献中发现，没有串联补偿的功率传输导致瞬态电流和电压的增加。因此，在传输线的正常和故障情况下，采用固定的串联补偿方案可以解决上述使用MATLAB / SIMULINK的问题。此外，本文还介绍了在传输线中添加两个与合适的保护系统关联的补偿单元的方法。此技术可以提高500 kV超高压输电线路的性能，并减轻各种类型的故障（例如相接地（Ph-G），双相接地（2Ph-G），三相接地）中的故障电流幅度（3Ph-G）。另外，关于扰动期间串联电容器组两端的过电压问题，该系统通过与合适的控制系统相关的保护技术得到了增强。该设计被插入到系统中以保护串联电容器组，从而克服了几种类型的故障条件下过压的严重性。它还在MATLAB / SIMULINK的帮助下进行了仿真和评估。考虑到干扰期间串联电容器组上的过电压问题，该系统通过与合适的控制系统相关的保护技术得到了增强。该设计被插入到系统中以保护串联电容器组，从而克服了几种类型的故障条件下过压的严重性。它还在MATLAB / SIMULINK的帮助下进行了仿真和评估。考虑到干扰期间串联电容器组上的过电压问题，该系统通过与合适的控制系统相关的保护技术得到了增强。该设计被插入到系统中以保护串联电容器组，从而克服了几种类型的故障条件下过压的严重性。它还在MATLAB / SIMULINK的帮助下进行了仿真和评估。
