背景技术Background technique
向相关联的电网设备（例如，输电线路在线监测装置）进行供电可以保证电网设备的正常运行。目前，向电网设备进行供电，通常采用的方式为：单独采用太阳能供电系统进行供电，或单独通过取电互感器向一次线路取电的方式来向电网设备进行供电。Supplying power to associated grid equipment (for example, transmission line online monitoring devices) can ensure the normal operation of the grid equipment. At present, power is usually provided to grid equipment by using a solar power supply system alone, or by taking power from a primary line through a power transformer.
然而，采用上述方式通常存在以下技术问题：However, there are usually the following technical problems with the above approach:
第一，由于太阳能电池板只能在阳光充足的环境下将太阳能转换成电能，而在阳光不充足的环境下无法获取到太阳能，导致难以对相关联的电网设备进行供电；First, since solar panels can only convert solar energy into electrical energy in an environment with sufficient sunlight, but cannot obtain solar energy in an environment with insufficient sunlight, it makes it difficult to supply power to related grid equipment;
第二，当取电互感器从一次线路采集到的电能大于相关联的电网设备所需要的电能时，取电互感器会将采集到的电能均传输至相关联的电网设备，从而导致电能资源的浪费；Second, when the power collected by the power transformer from the primary line is greater than the power required by the associated power grid equipment, the power transformer will transmit all the collected power to the associated power grid equipment, resulting in a loss of power resources. waste;
第三，当一次线路负荷电流较低时，取电互感器难以向一次线路取电，导致无法对相关联的电网设备进行供电。Third, when the load current of the primary line is low, it is difficult for the power transformer to draw power from the primary line, resulting in the inability to supply power to the associated power grid equipment.
