摘要
针对常规技术中变电站离线监测效率低的问题,研究了新型的在线监测方法。建立了电能损耗数值计算模型,反映出有功、无功、空载、负载损耗之间的关系,设计了单向树搜索法,能够优选功率损耗最小的变压器并列运行方式,最大程度地减少了损耗。设计出新型数据采集器,利用信息融合技术对采集到的信息进行综合处理和协调优化,最终实现变压器的在线监测流程。实验表明,所提方法的监测方法误差在10%以内,可靠性好。
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.
