摘要：

In this paper, ETAP (Electrical Transient Analyzer Program) GUI (Graphical User Interface) simulation tool has been used to perform the short circuit analysis of power transmission lines. The existing 500KV Hubco-Jamshoro Transmission network of National Transmission & Dispatch Company, Pakistan has been selected to simulate the network. We provide a method for the analysis of short circuit current values for four different faults, i.e. 3-phase, line-ground, line-line and line-line-ground. It also covers the improvement of voltage stability of the network after integration with proposed projects of Jhimpir and Gharo wind power plants. The results of 3-phase and single phase line to ground faults are carried out using conventional method and to validate them these are compared with that of simulated ones. This paper also provides a way of improvement in voltage stability of Hubco-Jamshoro transmission network after adding the proposed projects of wind power plants at Jhimpir and Gharo.
