In order to meet rapidity and reliability of leakage protection, transient zero-sequence current wave form difference characteristics between leakage line and normal line is give through theory analysis; A novel leakage line detection method using multi-correlation criterion fusion is presented. According zero sequence wave form characteristics, by D-S evidence theory, from making of leakage measures,...
Analysis of regional power demand cycle is the foundation of researching the national power demand cycle. Firstly the growth rate data of power demand in China from 1994 to 2005 is dealt with the H-P filter, and the periodicity factors of the nation and provinces power demand are obtained. Secondly the periodicity factors of the provinces power demand are treated with cluster analysis, and the problem...
A deregulated power market is making short-circuit currents likely to exceed the thermal or mechanical permissible limits of switchgear. Consequently fault current limiters (FCL) become more applicable in power systems. The use of FCLs has an impact on the protection schemes and functions in electrical systems. Thus, before FCLs will be applied in the network the interactions between this new substation...
As an experimental tool for analyzing movement of chaos, we intend to introduce the correlation dimension for analyzing vibration signals of rotor system in this paper. For noise corruption existing in field-measured vibration signal, morphological filter is also introduced for de-noising the vibration signal. The analysis and comparison between the correlation dimensions of the noised and de-noised...
