Abstract

Abstract: The common ground pole design of multi-circuit UHVDC/HVDC system has become the developing trend of UHVDC/HVDC system ground pole design in order to save pole sites and cost. At present, position and status of the electrode side disconnector can only be monitored manually which is inefficient and expensive for the project life cycle. A feasible scheme based on GPRS/CDMA communication technology and solar wind hybrid power generation is proposed to provide cost effective and efficient disconnector remote monitoring for system opeartion and construction. The method adpots many mature technologies such as GPRS/CDMA communication, clean energy generation, smart microgrid and high voltage insulation monitoring.

Key words: common grounding electrode, GPRS/CDMA technology, disconnector, monitoring scheme
