90년대 후반 부터의 초고압 XLPE 케이블 시스템의 연구개발 및 납품 성과에 힘입어 국내 업계 최초로 2006년 미국시에 345kV 광복합 XLPE 케이블 시스템을 수주하였다. 본 논문은 미국 뉴욕주 최대 전력시스템 운용 회사인 KeySpan사가 발주하여 LS전선이 Turn-Key 방식으로 수주, 뉴욕주 롱아일랜드에 성공적으로 준공하여 운전 중인 345kV XLPE 광복합 케이블 시스템 project에 대하여 기술하고 있다.

지중송전라인에서 전압등급의 상승은 선로손실을 줄이면서 밀집된 전력수요에 대응하거나 특별히 고전압 수요를 맞추기 위한 것으로 이것은 XLPE Cable의 제조기술이 향상되면서 지속적으로 진행되어온 초고압송전계통의 일반적 추세이다. 이러한 경향으로 국내에서는 지중송전선로로서 최고전압인 345kV가 시공되어 운전중에 있으며 해외에서는 220kV~275kV급을 넘어서 400kV급 초고압케이블라인의 수요가 증가하고 있는데, 이러한 지중송전라인의 초고압화는 높은 신뢰성이 함께 요구되며 특히 접속재 분야에서 매우 높은 신뢰성이 요구된다. 당사는 UAE 400kV AL TAWEELAH Project에 400kV XLPE 1Cx630SQ 광복합 초고압송전라인을 준공하였는데 본고에서는 여기에 적용된 400kV XLPE 1Cx630SQ 광복합 케이블 부속재의 신뢰성을 높이기 위한 설계방법, 시험 및 시공에 대하여 요약하였다.

In this study, We developed the optical fiber incorporated high-voltage underground power cable which is combined optical fibers with conventional high-voltage underground power cable. Optical-Unit that optical fiber is inserted in stainless tube is tested, and we got good results enough to safe optical fibers. Also we put the optical fiber incorporated high-voltage underground power cable to the test of electrical characteristics and optical characteristics, we knew that the electrical characteristics were the same characteristics as conventional high-voltage underground power cable and the transmission loss change was almost zero.

Since power system is switching to smart grid, on-line monitoring technology has become necessary for underground distribution power cable. Therefore, the application of DTS(Distributed Temperature Sensing) technology using OFCPC(Optical Fiber Composite Power Cable) capable of monitoring underground distribution power cables has been developed. These can bring about reductions in faults and increases in operating capacity of underground distribution system. To date, the test-bed of optical fiber composite power cable on-line monitoring system has been constructed. Then, matters to be improved have been drawn through verification experiments. This paper presents the improvement and experiment results of the optical fiber composite power cable on-line monitoring system to apply to underground distribution lines in the field.

Intelligent distribution equipment is inevitable to realize self-healing which is one of smart grid functions in distribution network. Therefore, most of distribution equipment have been developed with self diagnostic sensors. However, it is not effective to construct on-line monitoring system for underground distribution cable because of high cost and low sensitivity. Recently, optical fiber composite cable is being considered for communication and power delivery in order to cope with increasing communication in distribution network. This paper presents the design and performance assessment results of underground cable on-line monitoring system using DTS(Distributed Temperature Sensing) and optical fiber composite underground cable.
