The accurate and rapid detection of voltage and current in non-sinusoidal and unbalanced voltage condition is the prerequisite for grid power quality management and stable operation. Based on analyzing the vectors of the grid voltage and current, the rotating vector detection is carried out which can detect the voltage and current specified harmonic component and reactive and active current in non-sinusoidal...
Traditional methods for positioning accuracy is not high and takes long time consuming problem. A real-time positioning algorithm is proposed based on improved median filter people trapped in the thick fog. first of all, Visual zoning of heavy fog environment is initialized, after initialization operation, to average filtering processing of heavy fog environment, and the heavy fog in the environment...
