Title

Development of Algorithm based on Block Pulse Function for Numerical Differential Protection of Synchronous Generator

Abstract

A synchronous generator, which is major and very important equipment in a power system, requires very efficient and reliable protection scheme. Percentage differential relays of electromagnetic and static type are conventionally used for protection of synchronous generator against internal faults. With the advent of fast and sophisticated microprocessor and special purpose processor, there is a growing trend it design and develop digital processing relays. The main features of digital relay are there economy, compactness and improved performance over conventional relays. In digital relaying scheme processor acquires the digitized samples of relaying signals and processors under the elaborate program control to extract the fault discriminate. The digital filtering algorithms for differential protection of synchronous generator extract the fundamental and second harmonic frequency components of the differential current it provide the operating and restraint signals respectively. The work described in this paper deals with the development of a digital filtering algorithms based Block Pulse Function (BPF) for the differential protection of synchronous generator for its high speed of response, computational burden, simplicity and accuracy and the capability to extract the fundamental and other harmonic components from post fault signal and to check the suitability of the algorithm for the digital differential protection of synchronous generator. In the present work an attempt has been made to calculate fundamental component and second harmonic component by relationship developed between Fourier and BPF coefficients. By choose test signal, it has been found that BPF algorithm is suitable for the numerical differential protection of synchronous generator.
