Narrowband, low data rate communications on the low-voltage mains in the CENELEC frequencies. II. Multiplicative signal fading and efficient modulation schemesIEEE Transactions on Power Delivery - Tập 17 Số 3 - Trang 724-729 - 2002
D. Cooper, T. Jeans
This is the second of a two-part series on communications over the European 240 V domestic powerline, in the frequencies identified by the CENELEC European mains signalling standard, suitable for low-cost equipment in applications requiring data rates of no more than hundreds of bits per second (b/s). To minimize costs, narrow-band modulation techniques are considered. The series of two papers ide...... hiện toàn bộ

Adaptive power flow method for distribution systems with dispersed generationIEEE Transactions on Power Delivery - Tập 17 Số 3 - Trang 822-827 - 2002
Y. Zhu, K. Tomsovic
There has been great interest in the integration of dispersed generation units at the distribution level. This requires new analysis tools for understanding system performance. This paper presents an adaptive distributed power flow solution method based on the compensation-based method. The comprehensive distributed system model includes 3-phase nonlinear loads, lines, capacitors, transformers, an...... hiện toàn bộ

An accurate fault classification technique for power system monitoring devicesIEEE Transactions on Power Delivery - Tập 17 Số 3 - Trang 684-690 - 2002
T. Adu
This paper presents a novel method of classifying transmission line shunt faults. Most algorithms employed for analyzing fault data require that the fault type be classified. The older fault-type classification algorithms are inefficient because they are not effective under certain operating conditions of the power system and may not be able to accurately select the faulted transmission line if th...... hiện toàn bộ
