We find out the ground faults quickly they are more important for safety, economy and electric power quality. Thus it is essential to detect and analysis the fault quickly and separate the faulty part of the HV transmission line. The deformation of insulator materials are also to occurs a short circuit faults. A flash over, lightning strikes to birds, wind, snow and ice load lead to short circuits. So, it is necessary to determine the types of fault and location of fault on the transmission line and clear the faults as soon as possible in order not to cause some damages. When there a major fault which occurring on long transmission lines not only affects the all equipment and it also effect the electrical power quality. L-G, LL-G and LLL- G faults gradually rise to serious damage on electrical power system equipment. When different fault are occurred two or more conductors come in contact to each other or ground in three phase systems, for it is at such times that the electrical power system components are the greatest stresses from excessive currents. Simulation is done by using MATLAB simulation in computer and then analysis of Maximum voltage transmission line faults can be easily Detect and analysis. The triple line fault current is much higher as compare to other faults current. Protected system are circuit breakers and its rating is totally depends on L-L-L fault. The extra high voltage transmission line fault detection and analysis helps to selected and developing for a better to protection purpose and their protection of transmission line. In this case of three phases electrical power system mainly they are two faults occurs such as three phase balance fault and three phase unbalance fault on transmission line of electrical power system faults are classified are L-G fault, 2L-G fault and 3L-G fault. This methods to find out such types of fault analysis and detection, direction estimation and faults distance location can be classified into the following three categories name are transient signals-based methods, power frequency components- based methods and superimposed components-based methods The main purpose is to study the general fault types which are balance and unbalance faults of long transmission line in the electrical power system and we have to perform the detect and analysis and obtain the result of various MATLAB software. The electrical power system is terms bus voltage and bus current of high transmission line are very important. In High Voltage Transmission lines there are different types of fault occurs in electrical power system and then in the process of ,transmission line fault analysis and detection, determination of bus voltage and the line current. Keywords UHV Transmission line, MATLAB Software, L-G fault. The whole simulation of different operating and different conditions of fault on UHV transmission line, their faults are L-G fault, LL-G fault, and LLL-G fault circuit of the proposed all work presented in this Report.
#Modelling analysis using power world simulator software#
The Complete proposed model of HV transmission lines are simulated in MATLAB software to Detect and Identified the faults.Fault element was taken from the Sim-Power system block library. The major faults in HV transmission lines is Single Line to Ground Fault which are harmful to the electrical equipment. These types faults are affecting the electrical power system component which are connect in High Voltage Transmission Line. During some faults are occurred in the High Voltage transmission line system, such as Single Line to Ground Fault (L-G), Double Line to Ground (LL-G), Triple Line to Ground Fault (LLL-G) and Line to Line fault (L-L). Pranay Anil Kulkarni Department of Electrical EngineeringĪbstract- Electrical power is increases day by day and transmits more electrical power transmission line capacity from one station to another station.The main aim of this project is to detect and identified the location of the different faults on High transmission lines.
