Description

一种有轨电车非接触供电和接触供电共存的供电系统
技术领域
本发明属于城市轨道交通新型供电系统的实际应用领域，具体涉及一种有轨电车非接触供电和接触供电共存的供电系统。
背景技术
伴随着城市化建设的推进及汽车产业的发展，我国城市交通压力问题日益严峻。为缓解拥堵，改善交通，多种形式的城市轨道交通工具得到快速发展，包括地铁、轻轨、市域铁路、有轨电车和中低速磁浮等。其中地铁以其环境友好、运行速度快，载客量大等优势发展最为迅猛，但是地铁建设受到了城市GDP、人口等客观因素的制约，且地铁建设周期十分漫长，难以满足当前迫切的交通需求。作为地铁系统的重要补充，中运量的有轨电车进入人们的视野。目前北京、上海、广州、武汉、苏州、成都等多个大城市已经实现了有轨电车线路的运营，另有多条有轨电车线路项目正在积极的规划和建设中。
有轨电车线路往往采用受电弓从架空接触网受流，钢轨回流的方式对列车进行供电，这种供电方式结构简单，建设及维护成本低，但是城市的景观有不小的负面影响，尤其是在道路交叉口，架空接触网带来的视觉污染是冲击性的。
为了调和有轨电车安全供电与城市美观之间的矛盾，可以考虑采用非接触供电的方式。但非接触供电系统同时也面临着控制系统复杂、建设及维护成本高、再生制动能量无法反馈回电网、电能质量较差等一系列问题，因此非接触供电系统难以大规模使用。当有轨电车线路的部分路段对城市景观的要求较高时，这部分路段可采用非接触供电系统，其余路段仍采用成熟的架空接触网供电系统。
发明内容
为了克服上述问题，本发明提供一种有轨电车非接触供电和接触供电共存的供电系统。
本发明的有轨电车非接触供电和接触供电共存的供电系统包括非接触供电区域、接触供电区域和无电区域，该供电系统中所用列车为双流制列车。
在接触供电区域，电能经牵引变电所传送至接触网上，列车受电弓受流，经牵引变流器给牵引电机供电，再经钢轨和回流线回到牵引变电所负极。
在非接触供电区域，电能经牵引变电所传送至电能变换装置，电能变换装置将直流电逆变为高频交流电，经谐振补偿装置和发射线圈发射，列车拾取线圈上感应出高频交流电，通过另一个谐振补偿装置、整流滤波装置、DC-DC变换器和逆变装置为牵引电机供电。
牵引变电所将城市电网AC 10kV作为外部电源，经所内整流设备转换为DC 750V输出。
进一步的，供电系统的某个牵引变电所只为非接触供电区域供电，则该牵引变电所不安装再生能量吸收装置。
进一步的，列车中不同制式的牵引传动系统安装在不同的车厢。
进一步的，牵引变电所包括若干发射线圈组，每个发射线圈组包括一个电能变换装置、谐振补偿装置和发射线圈。
本发明与现有技术相比的有益技术效果为：
本发明的非接触供电克服了导线裸露、器件磨损、接触电火花等一系列问题，具有便捷、灵活、安全及环境友好等优点，能有效化解供电安全可靠性和城市景观之间的矛盾。同时结合接触供电以降低制造和维护成本。
附图说明
图1为本发明有轨电车非接触供电和接触供电共存的供电系统示意图。
图2为本发明双流制列车示意图。
图3、图4为本发明发射线圈换流方案示意图。
具体实施方式
以下结合附图和具体实施例对本发明作进一步详细论述。
本发明的有轨电车非接触供电和接触供电共存的供电系统如图1所示，该供电系统可在现有接触式有轨电车供电系统的基础上进行改造或者新建。该供电系统的供电区域包括非接触供电区域、接触供电区域和无电区域，供电系统中的非接触供电区域和接触供电区域均由牵引变电所SS供电。
如图2所示，该供电系统中所用列车为双流制列车，包括两套牵引传动系统，其中一套为直流制式，一套为交流制式。为降低不同制式设备之间的短路风险和控制难度，提高系统的安全可靠性，将不同制式的牵引传动系统安装在不同的车厢。
牵引变电所SS沿用现有城市轨道供电系统中的牵引变电所设计方法，所内主要设备为整流机组，配电变压器，再生能量吸收装置等。由于非接触供电区域的再生制动能量无法反馈回交流侧，若该供电系统的某个牵引变电所只为非接触供电区域供电，则该牵引变电所无需安装再生能量吸收装置，以节约投资建设成本。
供电系统中的牵引变电所将城市电网AC 10kV作为外部电源，经所内整流设备转换为DC 750V输出。在接触供电区域，DC 750V电能传送至接触网上，列车受电弓受流，经牵引变流器给牵引电机供电，再经钢轨和回流线回到牵引变电所负极。在非接触供电区域，DC750V电能传送至电能变换装置PCDi，电能变换装置PCDi将直流电逆变为高频交流电，经谐振补偿装置PHCi和发射线圈发射，列车拾取线圈上感应出高频交流电，通过谐振补偿装置、整流滤波装置、DC-DC变换器和逆变装置为牵引电机供电。
由于发射线圈通过的是高频的交流电，高频交流电附近会感应出电磁场，如果长期暴露在空气中会产生一定的安全隐患，因此只有当列车行驶在发射线圈上方时，发射线圈接通，当列车驶离发射线圈时，发射线圈关断。
由于有轨电车的行进方向是固定的，那么只需检测列车的位置就可以确定某固定发射线圈的关断情况。参见图3、图4所示。图3中，Sn-1为位置传感器，当列车行进到图示位置时，位置传感器Sn-1检测到列车的存在，此时，位置传感器Sn-1向下一个发射线圈的换流控制器发射信号，将发射线圈Ln的状态由关断切换为开通。图4中，拾取线圈中的S0为高频信号发射线圈，高频信号发射线圈S0中通过一个高频的小电流信号，高频信号发射线圈S0中电流的频率比拾取线圈的电流频率大一个数量级，因此高频信号发射线圈S0与拾取线圈之间的耦合效应可忽略不计。发射线圈中加入辅助检测线圈Ti,开路形式放置。当高频信号发射线圈S0经过辅助检测线圈Ti上方，辅助检测线圈Ti可检测到开路电压，如图4所示，高频信号发射线圈S0行驶至图示位置，这时，辅助检测线圈Tn向上一个发射线圈的换流控制器发射信号，将发射线圈Ln-1的状态由开通切换为关断。
