paper introduces a quick classification method of the power quality
disturbances. Based on analyzing the characteristics of different electrical
disturbance signals in time domain, four distinctive features are extracted
from electrical signals for classifying different power quality disturbances
and then an automatic classifier is proposed. Using the proposed classification
method,a PQ monitor of the classifying
power quality disturbances is developed based on the TMS320F2812DSP
micro-processor. Semi-physical simulation, lab experiment and field measurement
results have verified that this proposed method can classify single or complex
disturbance signals effectively.
Based on the analysis of the theories of value chain and multinational merger and acquisition, we research the merger and acquisition of petrochemical industries based on value chain, according to the trait of the value chain of the petrochemical industries. And we propose the implementation process and the integration method for the merger and acquisition of petrochemical industries based on value chain.
