As the smart grid concepts are emphasized lately the need to modernize the power engineering education is also well recognized. This paper presents a set of newly developed modeling, simulation and testing tools aimed at better understanding the design concept and related applications for protective relaying and substation automation solutions for the smart grid. Since the smart grid applications...
DC offset has significant effect on extracting fundamental frequency components. It directly impacts the accuracy of the fundamental frequency component based protective relaying algorithms. This paper proposes a novel method for estimating the fundamental phasor while eliminating the DC offset using improved recursive wavelet transform. The proposed approach converges to the actual value in less...
This paper presents a new test methodology for evaluating the security and dependability of protective relay operations. A discussion of the important impact of relay security and dependability on power system reliability especially during cascading events and unusual operating conditions is presented. The new test methodology includes comprehensive power network modeling, generating test scenarios...
Transmission line protective relays are assuring normal operation of power system by automatically isolating faulted sections. Different disturbances in power system could affect relay behavior and may result in relay misoperation or unintended operation. This paper explores various aspect of the performance analysis of existing protective relays. Three categories of solutions are discussed: 1) relay...
