基于DSP的变压器局部放电在线监测系统
DEVELOPMENT ON THE PARTIAL DISCHARGE ON-LINE MONITORING SYSTEM OF TRANSFORMER BASED ON DSP
【摘要】 作为电网中重要设备之一 ,电力变压器的正常工作与否直接影响电网的安全稳定运行。变压器的局部放电信号是判断其工作状态的重要参数。本文介绍了一种基于DSP处理器的变压器局部放电在线监测系统 ,实现对变压器绝缘状态的监测。该系统充分利用其强大而高速的数据处理能力对采集的局部放电数据进行快速、复杂的运算。本文主要介绍了该系统的检测原理、整体结构及硬件构成
【Abstract】 It is well known that the transformer is one of the most important equipments in power system and its operation condition greatly influences the safety of power system.The Partial Discharge (PD),as one of the important parameters,can be monitored to inspect the insulation condition of transformer.In this paper,a PD on line monitoring system for transformer based on the Digital Signal Processor (DSP) is developed.In this system,the DSP,possessing of powerful and high speed data treatment ability,can complete the complex mathematic operation to PD data.The measurement principle,the structure of the whole system and the hardware are detailedly introduced in this paper.
