PPT-Novel Protection Schemes for HVDC System

Inventors Alex Huang aqhuangncsuedu Chang Peng cpeng3ncsuedu Background DC transmission and distribution systems are more efficient when compared with traditional AC transmission system and therefore is gaining significantly market share in todays electric power grid. -through a series of public measures against economic and social distress. -caused by stoppages or substantial reduction of earnings. -resulting from sickness, maternity, employment injury, unemployment, disability, old age, death, provision of medical subsidies for families with children..
