Research And Application Of Setting Method For Relay Protection Of Nuclear Power Plant

With the enlargement of power system,the causes of blackouts became more and more complicated.The blackout in USA and Canada happened in 2003 makes people pay attention to the large area blackout.With Suzhou’s rapid economic and social development and the city’s electricity consumption,the rapid growth of electricity load,the power system of Suzhou has achieved a leapfrog development.The scale and capacity of the grid rapidly evolving,electric power safeguard ability and grid operation and management level have improved significantly.But the risk of blackouts in Suzhou still exists.So it is necessary to carry out the research of black start scheme for Suzhou’s power grid and formulate feasible scheme.Starting from the actual situation of Suzhou power grid,the article elaborates the grid black start program of Suzhou,and give an outline of the feasibility of distributed generation in black start.It explicits the black-start power and recovery path of Suzhou gird black-start,the black-start process is studied and calculated.It also introduces the matters needing attention in black-start process.And work out the black-start scheme of Suzhou’s power grid,,makes the black start scheme for Suzhou’s power grid has a strong practical operablility...
