摘要
传统方法在分析同期线损系统线路空载、轻载损耗时,计算量过大,抗干扰能力很差。针对上述问题,分别对同期线损系统线路空载、轻载损耗进行研究,当线路两侧的断路器处于停处热备用状态、停处冷备用状态、停处检修状态时,线损系统线路会出现空载,通过计算线损耗电量AP,计算出线损率,以数据采集层、数据处理层和数据应用层建立管理模型,解决同期线损系统线路空载损耗量过大这一问题。变换器的一些主要元器件或部分磁性元件出现问题会造成轻载损耗,轻载损耗量计算过程分为参数输入、线路负载电流计算、线损率计算三步。与传统研究方法进行对比实验,结果证明,给出的同期线损系统线路空载、轻载损耗研究方法计算过程简单,抗干扰能力强,具有很大的发展空间。
The traditional method has too much calculation and poor anti-jamming ability when analyzing the no-load and light-load losses of line loss system in the same period.Aiming at the above problems,the no-load and light-load losses of line loss system in the same period are studied separately.When the circuit breakers on both sides of the line are in hot standby state at the stop,cold standby state at the stop and maintenance state at the stop,no-load will occur on line loss system lines.By calculating line loss power,line loss rate is calculated to collect data.Layer,data processing layer and data application layer establish management model is used to solve the problem of excessive no-load loss of line loss system in the same period.Some main components or some magnetic components of the converter will cause light-load loss.The calculation process of light-load loss can be divided into three steps:parameter input,line load current calculation and line loss rate calculation.Compared with the traditional research methods,the results show that the proposed research methods for line loss system with no-load and light-load are simple in calculating process,strong in anti-interference ability,and have great development space.
