Intelligent Management Design on Air Conditioning Nonlinear Group Load

Abstract

Large-scale accessing to the power grid of non-linear load affects the power quality of the grid. The monitoring requirements of load electrical characteristics are more urgent with rapid increase in power energy demand. Aiming at the characteristics of non-linear group load operation of air conditioners, a systematic monitor project construction scheme is proposed. Firstly, the simulation software is used to build air-conditioning nonlinear group load model to observe characteristics and performance. Then, according to the energy characteristics of the nonlinear group load, the parameters and control variables, the data communication between the monitoring environment and the non-linear load operating simulation environment is designed, and the electrical characteristics of the nonlinear group load are monitored dynamically. Finally, the waveform analysis of the electrical characteristics is done and given the analysis result. Appropriating measures are taken to make the power quality meet the actual requirements, active power management is achieved in demand side.
