    The complexity of the power system increases as hundreds of lines due to the penetration of conventional and non-conventional energy sources. Transmitting the power for hundreds of kilometres through large number of transmission lines makes complexity in the network to locate the fault. Thus it is necessary to develop suitable algorithms to identify the location of the fault accurately in presence of large number of transmission lines. In this paper a novel Wavelet-ANN (Artificial Neural Network) based method is developed where the Detailed coefficients (D1 coefficients) obtained from post current signals are used for wavelet analysis. The D1 coefficients obtained from wavelet analysis are used for training and testing ANN at various distances. This analysis is worked out almost within half cycle. The fault location is carried out for various distances, fault impedance's on 2-bus connected transmission system. A 2-bus transmission system is simulated using simulation software and the analysis of fault is done by wavelet analysis. The proposed wavelet based algorithm is tested for all fault conditions at the faulted area and hence it is proved that the proposed method provided the best results for different fault impedance's, fault generator capacities, fault inception angles (FIA).

    This paper presents a novel protection scheme for the protection of transmission system with microgrid (MG) having of wind energy, solar PV energy and fuel cell sources. MGs provide environmental, economical benefits for the end consumers, power usages and society. However, transmission line and MGs poses major technical challenges. Protection system must respond both MG and utility grid failures. Technical challenges of MG protection are to respond to main and MG faults. A MG model is designed and it is connected to a transmission line. Later, for detection and classification of faults wavelet Analysis (WT) is used. Faults are detected by the fault indices and compared with defined threshold value. The location of fault is done by artificial neural networks (ANN) on MG connected transmission system using detailed (D1) coefficients of energy current signals. This proposed algorithm is tested and more effective for the detection, classification and location of faults on MG interconnected transmission system. This algorithm is accurate and independent of fault inception angle (FIA), fault impedance and fault distance on line.
  • Renewable energy integrated multi-terminal transmission system using wavelet based protection scheme

    International Journal of Power Electronics and Drive Systems, 2019
    The power plants behavior is crucial under faulted conditions and responses on protection systems. Major microgrid (MG) protection problem is the problem between the fault current in utilitygrid mode and microgrid mode. As conventional protection system doesn’t offer solution for all MG protection challenge, but it needs advanced protection strategy. Protection system must response to both the utilitygrid and MG faults. Fast response of protection is necessary as early as possible if the fault is occurs on utilitygrid and if the fault is occurs on MG, the protection scheme must seperate the small possible portion of MG to remove the fault. This work presents a typical MG protection scheme using digital relaying and satellite communication with wavelet detailed D<sub>1</sub>-coefficients of mother wavelet Bior 1.5. This research work is done for the detection, discrimination and locality of faults at distributed generators (DG’s) integration in multi-terminal transmission system. The algorithm tested under various faults with fault inception angles (FIA), fault impedances and fault distance of feeder line.
  • A transient current based micro-grid connected power system protection scheme using wavelet approach
    S. Chandra Shekar, G.Ravi Kumar, S.V.N.L Lalitha
    International Journal of Electrical and Computer Engineering, 2019
    Micro-grids comprise Distributed Energy Resources (DER’s) with low voltage distribution networks having controllable loads those can operate with different voltage levels are connected to the micro-grid and operated in grid mode or islanding mode in a coordinated way of control. DER’s provides clear environment-economical benefits for society and consumer utilities. But their development poses great technical challenges mainly protection of main and micro grid. Protection scheme must have to respond to both the main grid and micro-grid faults. If the fault is occurs on main grid, the response must isolate the DER’s from the main grid rapidly to protect the system loads. If the fault ocuurs within the micro-grid, the protection scheme must coordinate and isolates the least priority possible part of the grid to eliminate the fault. In order to deal with the bidirectional energy flow due to large numbers of micro sources new protection schemes are required. The system is simulated using MATLAB Wavelet Tool box and Wavelet based Multi-resolution Analysis is considered. Wavelet based Multi-resolution Analysis is used for detection, discrimination and location of faults on transmission network. This paper is discussed a transient current based micro-grid connected power system protection scheme using Wavelet Approach described on wavelet detailed-coefficients of Mother Biorthogonal 1.5 wavelet. The proposed algorithm is tested in micro-grid connected power systems environment and proved for the detection, discrimination and location of faults which is almost independent of fault impedance, fault inception angle (FIA) and fault distance of feeder line.
