Title

A wavelet based protection scheme for micro-grid with multiple distributed generations and Static Var Compensator

Abstract

Microgrid technology can effectively integrate the advantages of distributed generation, and also provide a new technical way for large scale application of grid-connected generation of new energy and renewable energy. Microgrid combines distributed power, load, energy storage devices and control devices, forming a single and controllable power supply system. Protection must respond to both utility grid and Microgrid faults. If the fault is on the utility grid, the desired response may be to isolate the Microgrid from the main utility as rapidly as necessary to protect the Microgrid loads. If the fault is within the Microgrid, the protection coordinator isolates the smallest possible section of the Microgrid to eliminate the fault. In order to cope with the bi-directional energy flow due to large numbers of micro sources new protection schemes are required. This paper proposes a protection scheme for microgrid with multiple distributed generations and Static Var Compensator using Wavelet based multi-resolution analysis is used to find the detailed coefficients of the signals to calculate the fault index. Fault indices of all phase currents at each terminal are obtained by analyzing the detail coefficients of current signals using bior 1.5 mother wavelet. The approximate decomposition of the current signals is utilized to detect and discriminate the faults from their respective terminals. This scheme is tested for various types of faults in the proposed system and it is found effective for detection of faults with various fault inception angle, the fault impedance at different distances with and without static var compensator.
