RECOGNITION METHOD OF POWER QUALITY DISTURBANCE SIGNALS BASE D ON IMAGE FEATURES
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
In order to meet the requirements of power quality monitoring and grid active control of distributed generation, in this paper, a new method to identify power quality transient disturbances by digital image processing is proposed. First, the power quality signal in the form of one-dimension time series was converted into two-dimensional digital image, and then the image feature enhancement was carried out by Gamma change. A unified feature extraction method of disturbance signal was established, and the automatic recognition method of disturbance type was established to improve the feature extraction efficiency. The results indicated that the proposed method performed a high efficiency and low hardware cost than existing methods in power quality signal recognition, which can further improve the power quality and reliability of distribution network
