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。

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.

Key words:information fusion technology; transformer reduction; online monitoring of energy consumption; operation switching times; one way tree search

在变电站中,主要有变压器、隔离开关、互感器、母线、避雷器、避雷针、电容器、电抗器、继电保护装置、电动装置、测控装置、计量装置等,其中变压器是變电站中电能损耗最高的设备,其使用量大,运行时间长,产生的电能损耗最多能够达到总发电量的10%,造成了大量的电能浪费[1]。目前对于变电站降耗与能耗监测的管控非常局限,仅仅依靠变电站离线的计量数据进行简单统计,无法及时且准确地掌握各部分的电损情况。电动装置是在变压器变压后进行分布式自动输出电力的一种装置,该种装置将变压后的电力集中在一起,根据各个供电局所计算出来的当地地区供电需求进行集中分布输出电力。

为了提高变压器损耗的测量精度,市面上已经出现了一……
