Description

一种抑制电力机车轴隔离后产生高次谐波的方法及系统 技术领域
本发明涉及电力机车运行技术领域,尤其涉及一种抑制电力机车轴隔离后产生高次谐波的方法及系统。
背景技术
随着电力机车的不断发展,电力机车在我国的保有量逐步变多,但同时由于电力机车的特殊性,尤其在不同机车混跑其IGBT开关频率不同时,在使用过程中会产生不同程度的高次谐波,这种高次谐波在接触网容量有限的情况下,由于电力机车在同一供电臂下的数量扩大,导致变电所在不扩容的前提下,无法吸收越来越多的电力机车高次谐波。
电力机车目前在切轴运用时,经过测量,会导致1800Hz附近高次谐波的增加,高次谐波的叠加,会导致其供电臂下的网压变高,严重时会超出机车允许接收网压的保护值,使机车断开主断路器,从而保护机车内部元器件不被损坏,但同时由于主断路器的断开,机车会失去牵引力,影响正常行车,严重时会造成机车晚点,影响运用秩序。
目前,抑制轴隔离导致高次谐波产生的方式为增加低通滤波器,既在接触网网压进入变流器前使用滤波器将多余的高次谐波过滤。具体地,其方式主要是在过滤高次谐波,使变流器在检测网压时将高次谐波过滤,从而避免机车因接触网网压高导致牵引封锁,但此种方法仅起到过滤的作用,但并未做到抑制高次谐波的产生,接触网上的高次谐波环境并未得到改善。
基于此,现有技术仍然有待改进。
发明内容

另一方面,本发明实施例还公开了一种电力机车,采用上述的抑制电力机车轴隔离后产生高次谐波的方法。
第三方面,本发明实施例还公开了一种电力机车轴隔离控制系统,其包括:
指令获取单元,所述指令获取单元用于获取轴隔离指令;
判断分析单元,所述判断分析单元基于所述指令获取单元获取额轴隔离指令,计算得到剩余工作轴的个数,并基于所述剩余工作轴的个数得出整流器相位再分配方案;
处理单元,所述处理单元基于所述整流器相位再分配方案控制剩余工作轴的整流器的相位再分配。
进一步地,所述相位再分配方案为对剩余工作轴的整流器相位平均分配。

采用上述技术方案,本发明至少具有如下有益效果:
本发明通过采用在轴隔离后对剩余轴进行相位再分配,有效拟制切轴运用时所产生的高次谐波,进而有效避免由此产生的供电臂下的网压变高所带来的不利后果。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。
图1为本发明一实施例所公开的实施例的对比图。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白,以下结合具体实施例,并参照附图,对本发明实施例进一步详细说明。
需要说明的是,本发明实施例中所有使用“第一”和“第二”的表述均是为了区分两个相同名称非相同的实体或者非相同的参量,可见“第一” “第二”仅为了表述的方便,不应理解为对本发明实施例的限定,后续实施例对此不再一一说明。
目前机车每个轴的载波相位为固定值,即使进行轴隔离操作,轴隔离后的载波相位也不发生改变,目前具体载波相位见表1。
表1
  CI1 CI2 CI3 CI4 CI5 CI6
无轴隔离时 120° 60° 150° 90° 30°
本发明要利用目前的载波相位模式,当任意轴被隔离时,对剩余工作轴的整流器相位进行分配调整,从而减少高次谐波的产生。具体地,本发明一些实施例公开了一种抑制电力机车轴隔离后产生高次谐波的方法,在任意轴被隔离时,对剩余工作轴的整流器相位进行再分配。具体地,所述对剩余工作轴的整流器相位进行再分配为对相位进行平均分配。
本发明一些实施例所公开的抑制电力机车轴隔离后产生高次谐波的方法中,控制系统基于操作端的轴隔离操作发出轴隔离指令;指令获取单元获取该轴隔离指令,并将该轴隔离指令传送至判断分析单元,判断分析单元基于所述轴隔离指令,得到剩余工作轴的数量,并基于剩余工作轴的数量对剩余工作轴的整流器相位进行再分配,得到剩余每个工作轴的相位。所述轴隔离指令包括单轴隔离,双轴隔离和多轴隔离中的任意一种。相位再分配优选采用平均分配的方式。通过平均分配剩余隔离州的整流器相位,抑制其高次谐波的产生,从而达到改善接触网环境,减少机车因网压高造成机车保护,减少机车非正常运用情况。
采用上述抑制电力机车轴隔离后产生高次谐波的方法的电力机车,当任意轴被隔离时,对剩余工作轴的整流器相位进行平均分配调整,从而减少高次谐波的产生。避免了供电臂下网压变高,进而避免了由于供电臂网压过高而超出机车允许接收网压的保护值,使机车断开主断路器以保护机车 内部元器件不被损坏的情况。进一步避免了机车会失去牵引力所导致的无法正常行车,机车晚点等。
本发明实施例还公开了一种电力机车轴隔离控制系统,其包括:
指令获取单元,所述指令获取单元用于获取轴隔离指令;
判断分析单元,所述判断分析单元基于所述指令获取单元获取额轴隔离指令,计算得到剩余工作轴的个数,并基于所述剩余工作轴的个数得出整流器相位再分配方案;
处理单元,所述处理单元基于所述整流器相位再分配方案控制剩余工作轴的整流器的相位再分配。
进一步地,所述相位再分配方案为对剩余工作轴的整流器相位平均分配。
本发明实施例还公开了一种计算机设备,包括:
至少一个处理器;以及
存储器,所述存储器存储有可在所述处理器上运行的计算机程序,所述处理器执行所述程序时执行上述的抑制电力机车轴隔离后产生高次谐波的方法。
一种计算机可读存储介质,所述计算机可读存储介质存储有计算机程序,所述计算机程序被处理器执行时执行上述的抑制电力机车轴隔离后产生高次谐波的方法。
本发明一实施例公开了一种电力机车,其采用上述的抑制电力机车轴隔离后产生高次谐波的方法,在不发生轴隔离操作时,载波相位如上表1所示,通过移相载波调整相位角后具体相位分配情况见表2。当任意轴被隔离时,对剩余工作轴的整流器相位进行平均分配调整。
表2
  CI1 CI2 CI3 CI4 CI5 CI6
CI1隔离 - 36° 72° 108° 144°
CI1,2隔离 - - 45° 90° 135°
CI1,2,3隔离 - - - 0 60° 120°
CI1,2,3,4隔离 - - - - 90°
CI1,2,3,4,5隔离 - - - - - 30°
通过软件变更后,经过软件装车测试,机车在1800Hz左右的高次谐波明显减少,具体对比如图1所示。当发生一个轴隔离至四个轴隔离时,未采用本发明的载波相位再分配的方法时,1800HZ谐波电流增加,采用本发明的载波相位再分配的方法时,1800HZ谐波电流减少。
