摘要： An underground power cable having an optical fiber sensor for measuring temperature distribution is disclosed. In the power cable, an optical fiber for measuring temperature distribution is received in a stainless steel tube having excellent strength, and this optical tube is interposed between a core and a sheath of the power cable. When arranging the optical tube in the power cable, a supporting material having a relatively low strength than the optical tube is arranged in the cable together in order to prevent the optical fiber from being damaged by external force and prevent the inner insulation layer from being broken down by the optical tube. In addition, a fixing tape for fixing the optical tube in contact with the core may be added to prevent the optical tube from being bent seriously or inclined to one side when the cable is bent.

The method includes: real-time measuring a surface distributed temperature of the link by using a distributed temperature sensor installed along a longitudinal direction of the link; calculating a conductor temperature of the link on the basis of the surface distributed temperature and an electric current flowing through the link; calculating a heat flow emitted out of the link on the basis of the surface distributed temperature and the conductor temperature; and real-time calculating a thermal parameter of an environment around the link on the basis of the heat flow. Thus, it is possible to calculate operating conditions of the link more accurately and improve safety of electric power transmission by real-time calculating the thermal parameter of the environment around the link.

摘要： A power conditioner for supplying controlled power generated from a power source such as a fuel cell or a solar battery to a load. The power conditioner includes a main converter converting the output voltage of the power source; an auxiliary converter converting the output voltage of the main converter to a voltage that is supplied to BOP elements; and a direct connecting line connecting the output voltage of the power source to the auxiliary converter bypassing the main converter. Accordingly, because the voltage for the power to be supplied to the BOP elements is converted only once, the power loss can be significantly reduced compared to the power loss from a conventional power conditioner.
摘要翻译：一种用于将诸如燃料电池或太阳能电池的电源产生的受控电力提供给负载的功率调节器。功率调节器包括转换电源的输出电压的主转换器; 辅助转换器将主转换器的输出电压转换为提供给BOP元件的电压; 以及将电源的输出电压连接到旁路主转换器的辅助转换器的直接连接线。因此，因为供给BOP元件的电力的电压仅被转换一次，所以与以往的功率调节器的功率损失相比，能够显着地降低功率损耗。
