An Integrated Protection and Control System for 10kV Electricity Distribution Networks Based on Package Transmission Communication Network
The application of a Wide Area Monitoring Protection and Control (WAMPAC) system in a 10 kV electricity distribution network (three 110 kV substations and nine 10kV ring main units) is presented in this paper. It provides current differential protection for 10kV feeders in order to meet the requirements of speed and selectivity of 10 kV feeder protection. The integrated protection and control system uses wide area information transmitted in Package Transmission communication Network (PTN) for feeder current differential protection, and to provide an auto-closing scheme for fast post-fault restoration of supplies. Laboratory tests and site trial have been done to prove the effectiveness of the system.
