Method For Substation Intelligent Consumption Reduction and Monitor Based on Information Fusion Technology
Abstract:Aiming at the low efficiency of offline monitoring of substations in conventional technologies, a new online monitoring method is studied.In this study, a numerical calculation model for power loss was established to reflect the relationship between active power, reactive power, no-load, and load loss. A one-way tree search method was designed to optimize the parallel operation mode of transformers with the smallest power loss and minimize loss.A one-way tree search method was designed, which can optimize the parallel operation mode of the transformer with the smallest power loss, and minimized the loss. A new type of data collector was designed, information fusion technology was used to comprehensively process and coordinate and optimize the collected information, and finally the online monitoring process of the transformerwasrealized.Tests show that the monitoring method error of the proposed method is within 10%,with the reliability is well.
